PAGE 2 ISSUE 17 • JUNE 2014 THE PUERTO RICAN SHARP-SHINNED HAWK ( ACCIPITER STRIATUS VENNATOR): AN ENDANGERED INSULAR SPECIES ON THE EDGE By Julio C. Gallardo, Department of Wildlife, Fisheries and Aquaculture, Box 9690, Mississippi State University, Mississippi State, Mississippi, 39762, USA jgallardo@cfr.msstate.edu; and Francisco J. Vilella, U. S. Geological Survey, Mississippi Cooperative Fish and Wildlife Research Unit, Department of Wildlife, Fisheries and Aquaculture, Box 9691, Mississippi State University, Mississippi State, Mississippi, 39762, USA fvilella@cfr.msstate.edu I Island communities are known for higher levels of species extinctions than their mainland counterparts (Diamond 1984, World Conservation Monitoring Centre 1992). Since 1600, more than 75% of the world’s animal extinctions have occurred on islands and are still ongoing (World Conservation Monitoring Centre 1992). Reasons for a higher extinction risk on islands are primarily related to biogeographic dynamics determined by island size, topography, disturbance regime and degree of isolation. However, anthropogenic in uences have played a pivotal role in the last 500 years. These include habitat loss and degradation, over-exploitation and invasive species (World Conservation Monitoring Centre 1992, Frankham 1998). The Sharp-shinned Hawk ( Accipiter striatus ) is a widespread bird-hunting raptor found in most forested habitats in North America. Approximately eight of ten described subspecies breed Puerto Rican Sharp-shinned Hawk male, perched near its nest, Maricao Commonwealth Forest, Puerto Rico, 2013 Julio C Gallardo

The Puerto Rican Sharp-shinned Hawk ( Accipiter striatus vennator ; hereafter SSHA) is an endangered woodland raptor known to inhabit mature and secondary montane forests and coffee plantations of Puerto Rico (USFWS 1997). The SSHA in Puerto Rico exhibits insular population traits, such as small clutches, reduced dispersion, low productivity, stable age structure, long breeding periods, and populations characterized by adult individuals (Delannoy 1984, Gliwicz 1980, Adler and Levins 1994, Stuchbury and Morton 2000). Available information on the SSHA indicates populations are small and mostly restricted to montane forest reserves; virtually no information exists of SSHA on private lands, particularly the coffee growing regions of the Cordillera Central. Based on limited available information, all Caribbean subspecies appear to be declining and in Puerto Rico the SSHA has exhibited a population reduction of 40% on public lands, where 240 individuals were estimated in 1985 and 150 in 1991 (Delannoy 1992, Bildstein and Meyer 2000, Fergurson-Lees & Christie 2001). During the last surveys (Delannoy 1997) conducted during 1991-1992, approximately 82 individuals were Puerto Rican Sharp-shinned Hawk, immature male, Maricao Commonwealth Forest, Puerto Rico, 2012 Julio C. Gallardo

PAGE 4 ISSUE 17 • JUNE 2014 recorded on ve reserves encompassing 285.6 km2. The Puerto Rico-GAP Analysis predicted a total of 84,859 ha of SSHA habitat, of these 24.4% is federal or state-owned protected areas (Gould 2007). The Puerto Rico Ornithological Atlas documents the species as con rmed in four quadrangles, possible in three, probable in one, and observed in one (SOPI 2010). Population decline in Puerto Rico may be a result of a series of factors namely habitat loss, forest fragmentation, high rate of nestling mortality from bot y parasitism ( Philornis spp .), and posthurricane changes in forest vegetation structure and consequent effects on SSHA avian prey (Wiley 1986, Delannoy and Cruz 1988, Wiley and Wunderle 1993). Despite its legal protection and an approved recovery plan (USFWS 1997), information on SSHA population status has not been updated for over twenty years, and no conservation efforts have been implemented. In 2011 we started research to derive population estimates (with precision) and identify important habitat characteristics for the SSHA. We selected the Maricao Commonwealth Forest (hereafter, Maricao Forest) as the primary study area since the region was documented to support the largest population of SSHA on the island (Delannoy 1991, Delannoy 1992). Our preliminary results suggest the status of the SSHA may be critical, necessitating an update of the status of the species along its known distribution, including public and private lands. Study Site Puerto Rico and its satellite islands (1745’ 1830’ N and 6545’, 6715’ W) represent the smallest and easternmost of the Greater Antilles, encompassing 8,740 km2 (Daly et al. 2003). The landscape of the main islands (Puerto Rico, Vieques and Culebra) is predominately mountainThe adult female feeds her two chicks at the nest. Mike Morel, 2011.

The SSHA in Puerto Rico is restricted to montane forests where breeding populations have been reported in the Maricao Commonwealth Forest, Toro Negro Commonwealth Forest, Guilarte Commonwealth Forest, Carite Commonwealth Forest, and the Caribbean National Forest (Delannoy 1997). Previous studies located 40 active nests in Maricao Forest associated with the Subtropical Wet Forest and Subtropical Lower Montane Forest in forests dominated by caobilla ( Podocarpus coriaceus ), caimitillo ( Microphoiis chrysophylloides ), and plantations of maria ( Calophyllum brasiliense ) between 400 to 900 m of altitude (Delannoy 1984, Delannoy and Cruz 1988, Delannoy 1997). One nest territory was found in subtropical moist forest in a maria plantation with similar structural characteristics of plantations at higher elevations (Delannoy 1984). The Sharp-shinned Hawk in Puerto Rico shows a noticeable sexual dimorphism typical of birdhunting raptors, where the female is larger than the male. Mike Morel, 2011.

PAGE 6 ISSUE 17 • JUNE 2014 Methods Recognizing that the SSHA in Puerto Rico naturally occurs in low densities, we developed a spatial model of suitable habitat in order to maximize effort. We used two habitat variables identi ed as important to SSHA from previous studies; a) canopy closure 60%, and b) elevation over 400 m (Delannoy 1984, Delannoy and Cruz 1988, Rivera-Miln 1995). To identify potential areas, we used percent canopy cover (Huang et al. 2004), elevation above 400 m (NOAA 2012), and land cover types from the Puerto Rico GAP Analysis (Gould et al. 2007).To facilitate SSHA detections, we used playback surveys as described in Henneman and Andersen (2009). This method has been used extensively to attract territorial forest raptors (including Accipiter spp .), especially during the breeding season (Rosend eld et al. 1988, Kimmel and Yhanel 1990, Bosakowski et al. 1992, Hargis and Woodbridge 2006). We set calling survey stations on public and private lands along Left: In previous studies, the bot y ( Philornis spp ) was responsible for 30% of nest failures and a mortality rate of 90% in infested chicks.

Survey stations were placed every 0.4 km based on the average distance (365 m) between SSHA nests reported in previous studies (Delannoy 1984). Survey periods covered approximately 4 hours after sunrise (0630 to 1030). We used recordings of local SSHA on a game caller with a hand-held ampli er for broadcast and remained at each station for 20 min, recording data in four periods as described in Mosher et al. (1990) and King et al. (2011). As a complement to these surveys, we conducted searches for breeding indicators in historical territories and aerial displays searches from overlooks to identify active territories. Preliminary results Maricao Forest, 2012-2014 Data collection was conducted from January to April of 2013 when SSHA more actively defend their territories (Delannoy 1984). We set 116 calling stations (58 on private lands and 58 on public lands) along 22 routes located mostly within the area identi ed by our GIS model. Monthly surveys conducted from January to April (308 person-hours) detected no more than 7 individuals. Also, we spent 179 hours searching for nesting activity in historical territories identi ed by Delannoy (1984) and were accompanied by Dr. Carlos Delannoy in some of our searches. We found a single territory previously identi ed during the calling stations surveys. No further evidence of territorial or breeding activity (i.e. old nests) was found in the remaining historical territories. We conducted 21 searches from overlooks located in historical territories, spending a total of 66 hours of observation. We detected SSHA activity three times from overlooks, but individuals were always observed going to or coming from previously identi ed territories. One single adult male (SM territory) and two active nests (total of 5 individuals) were found within the boundaries of Maricao Forest, one immature male was sighted on private lands, and one adult male in the Ro de Maricao Protected Area under the administration of the Puerto Rico Conservation Trust. Both active territories were found near the end of the breeding season of 2012 (summer). SSHA males were observed delivering avian prey to nesting females and chicks including; Puerto Rican Tanager ( Nesospingus speculiferus ), Bananaquit ( Coereba aveola ), Puerto Rican Oriole ( Icterus portoricensis) and Northern Parula ( Setophaga americana ). During the current 2014 breeding season we have extended our searches to seven forests where the SSHA has been previously reported. To date, we have conducted 36 overlook searches and have surveyed approximately 95 calling stations, mainly in Toro Negro Forest, Guilarte Forest, El Yunque National Forest, Cayey Forest, Bosque Escuela La Olimpia and Bosque del Pueblo, and on private lands. From February to mid-March we found a total of two active territories in Toro

PAGE 10

PAGE 8 ISSUE 17 • JUNE 2014 Negro, two in Bosque Escuela la Olimpia, one in Guilarte and a single male in Toro Negro, for a total of 11 individuals. The number of individuals detected in Maricao Forest is similar to our results from last year. Adults in the 2013 territories are incubating. However, in one of the territories there appears to be a solitary male vocalizing and rebuilding an old nest from 2011, but there is no evidence of a female in the area. Potential explanations for decline and future perspective The Sharp-shinned Hawk was rst described in Puerto Rico in 1917 (Friedmann 1959) at a time when approximately 94% of the island had been deforested. At present, approximately 40% of Puerto Rico is covered by mature (i.e., 60-year old) secondary forest (Grau et al. 2003). By 1976, the Conservation Committee of the American Ornithologists’ Union reported an estimated 100-200 SSHA island-wide. This resulted in a petition to the US Fish and Wildlife Service for listing under the Endangered Species Act, but it was not until 1997 when the species was nally listed (AOU 1976, Delannoy 1986, USFWS 1997). By 1991-1992 SSHA populations exhibited a 40% Apparently Sharp-shinned Hawks in Puerto Rico remain together year round; the male hunts and delivers food to the female and part of the breeding courtship.

Our preliminary ndings suggest a major SSHA decline, at least in its former stronghold, Maricao Forest. During 2012-2014 we have detected no more than 7 individuals after intensive and systematic searches within and beyond the boundaries of Maricao Forest. Previous studies estimated between 60-70 individuals in Maricao Forest by the late 1980s and 40 individuals by the early 1990s (Delannoy 1986, Delannoy 1992, Delannoy 1997). We located additional territories in other montane forests but these appear to be isolated, with individual territories more than 12 km apart, instead of the aggregated pattern observed during previous studies (Delannoy 1984, Delannoy 1992, Delannoy 1997). The population collapse of SSHA in Maricao Forest may be a result of a combination of factors such as changes in prey availability, abandonment of coffee plantations after the “coffee crisis” of Puerto Rico during the 1980s, and termination during the late 1990s of silviculture management practices in timber plantations where Delannoy (1984) found the greatest number of nests. Moreover, a primary reason for the observed collapse may be related to changes in forest structure following hurricanes Hugo (1989) and George (1998). Increased forest openings after hurricanes have an effect on bird communities with species depletions, increasing nest predation and parasitism (Wiley and Wunderle 1993). After hurricane Georges, bird populations in Maricao Forest exhibited a slow post-hurricane recovery and a rearrangement of forest strata use by some species (Tossas 2006). Hurricane Georges, which moved east to west across the Cordillera Central, may have resulted in remnant isolated patches of forest with suitable SSHA prey availability and adequate forest structure for nesting and hunting. Furthermore, there is no recent information on bot y (Philornis spp.) parasitism on SSHA. Delannoy (1984) reported high nest failure (72%) as a result of bot y parasitism on SSHA nestlings. Approximately 40% of SSHA nests were infested by bot ies resulting in about 30% nest failures and a chick mortality rate of approximately 90% (Delannoy 1984 ). Beyond the potential effects of hurricanes on SSHA habitat, population traits resulting from adaptations to a tropical island (such as reduced dispersion and low productivity) may limit SSHA population recovery. On a fragmented landscape where suitable habitat may be isolated, immigration, colonization and location of suitable mates may place an undue burden on individual SSHAs. Movement of individuals between montane reserves has not been reported for the species (Delannoy pers. comm.).

PAGE 10 ISSUE 17 • JUNE 2014 Our preliminary results suggest the SSHA in Puerto Rico shows a signi cant population reduction in the former stronghold of the species (Maricao Forest) and an isolated distribution of breeding territories located along the Cordillera Central. Urgent conservation and management action must be taken to prevent the extinction of this native insular predator. The SSHA in Puerto Rico may be on the edge of extinction despite being listed as an endangered species by the U.S. Fish and Wildlife Service and classi ed as “Critically Endangered” by the Puerto Rico Department of Natural and Environmental Resources. Recovery plans and listing criteria are no guarantee against extinction. Therefore, research on the factors responsible for this marked population decline and management approaches to protect and recover this insular forest raptor are needed.

PAGE 14 ISSUE 17 • JUNE 2014 T NEST RECORD OF THE STYGIAN OWL ( ASIO STYGIUS) IN GUATEMALA By Denver W. Holt Owl Research Institute, P.O. Box 39, Charlo, Montana, 59824, USA; Jess Lucus Yux Los Andes Private Nature Reserve, Santa Barbara, Suchitepquez, Guatemala; Stephen Hiro Owl Research Institute, P.O. Box 39, Charlo, Montana, 59824, USA; and Omar Mndez 7 Calle 12 – 85 Zona 16 La Montaa, Guatemala, Guatemala. Corresponding author: Denver W. Holt, e-mail: owlmontana@blackfoot.net. The Stygian Owl ( Asio stygius ) is a large owl, and distributed from the highlands of western Mexico, south and east through Central America (Belize, Guatemala, Honduras, and Nicaragua), the Caribbean (Cuba, Hispaniola, Isle of Pines) south to northwestern South America (Colombia, Ecuador, Peru, Venezuela), and central South America (Argentina, Bolivia, Brazil, Paraguay) (Holt et al. 1999, Knig and Weick 2008). It has been recorded from sea level to 3100 m elevation, associated with many types of forests, and perhaps occurs near natural openings, clearings, and farmlands (Holt et al. 1999, Knig and Weick 2008). The Stygian Owls’ distribution appears discontinuous, but this may re ect a lack of distributional records. Based upon DNA evidence, four subspecies are currently recognized (Knig and Weick 2008). The Stygian Owl is believed to be closely related to the smaller Long-eared Owl ( A. otus ) of North America (Holt et al. 1999). Due to its secretive diurnal roosting behavior, and nocturnal activity periods, very little is known Stygian Owl ( Asio stygius robustrus) photographed in the Mountain Pine Ridge, Belize. Ryan Phillips, Belize Raptor Research Institute

WWW.NEOTROPICALRAPTORS.ORG PAGE 15 about its overall ecology. Consequently, most information is the result of observations from few nests (Lopes et al. 2004, Phillips 2011). In fact, few nests have ever been found (Lopes et al. 2004), and only one nest has been studied thoroughly (Phillips 2011). It was previously thought Stygian Owls lay only two eggs, and nested from November through May (Holt et al. 1999) However, new data suggest the Stygian Owl may breed throughout the year, lay 2-3 eggs, and nest on the ground more commonly than previously known (Lopes et al. 2004, Phillips 2011). In Guatemala, the subspecies ( A. s. robustus ) is rarely reported, and its distribution poorly known (Eisermann and Avendao 2007). In fact, the Stygian Owl has been reported from only seven sites in all of Guatemala (Eisermann and Avendao 2007), and is critically endangered on a national level (Eisermann and Avendao 2006, Eiserman and Avendao 2007). An observation and photographs by Claudia Avendao, Knut Eisermann, and Jess Lucas Yuxn, in Los Andes Private Nature Reserve on 16 July 2008, constitute the rst documented observation for this species at Atitln Volcano (Jones and Komar 2009). Herein we report the rst con rmed nest record of Stygian Owl for Guatemala, in the same area as the 16 July 2008 observation. Study area and methods The observation took place at Los Andes Private Nature Reserve (LAPNR), which is part of Los Andes Coffee and Tea Plantation, Santa Barbara, Suchitepquez, Guatemala (14.528 N : 91.191 E). The plantation is a private property approximately 608 ha located on the southern slopes of Atitln Volcano, in western Guatemala’s volcanic chain. Elevation ranges from 900 to 1800 m. Los Andes is planted with coffee, tea, macadamia, and rubber. However, approximately 60% of the plantation remains as original primary tropical forest habitat, with higher elevations reaching cloud forest habitat. Annual precipitation is 4500 mm. In 2001, LAPNR became part of the Association of Private Nature Reserves of Guatemala (APNRG, www.reservasdeguatemala.org). The APNRG was founded by coffee plantation owners. Its mission is the conservation of the environment and to contribute to bird and wildlife conservation, among other interests. For example, LAPNR maintains a certi ed organic product status, and is dedicated to protecting the Resplendent Quetzal ( Pharomachrus mocinno ), and other tropical forest wildlife species. We observed the owls for approximately 30 minutes, using binoculars and a 20-60 power Nikon Field Scope. Results In January 2011, Jess Lucas Yuxn (JLY) located one or more Stygian Owls roosting in a Eucalyptus tree ( Eucalyptus torreliana ) at approximately 1300 m elevation, on the LAPNR. JLY intermittently observed the owls throughout January and

On the other hand, other studies indicate breeding at the end of the dry season/beginning of the wet season (Lopes et al. 2004) and wet season (Frantz 1991, Oliveiria 1981, Neto 1985). Thus, the Stygian owl breeding season may be in uenced by food abundance, not just climatic conditions. The senior author herein (DWH) has studied the congeneric Long-eared Owl for twenty-seven years in Montana, U.S.A. Thus, if Stygian Owls are similar to Long-eared Owls, then based on DWH’s years of experience, the young owl was estimated to be at least 4 weeks old. If correct, then back dating estimates of 4 weeks old, preceded by about 25 day incubation period, preceded by about 6 day egg laying interval for 3 eggs, and perhaps 7 days for courtship, would mean the owls probably bred in mid-to-late December. Los Andes owners were some of the founding members of a Private Nature Reserve network established by plantation owners to conserve tropical forests, and encourage nature tourism, such as bird watching. Los Andes is one of the few places in the world where coffee and tea are grown on the same site. The plantation is environmentally friendly and produces certi ed organic tea (USDA Certi ed) and certi ed responsible coffee (UTZ Certi ed). It is now home to one of the rarest breeding owl species in Guatemala. February. On 28 February while serving as our birding guide, JLY showed the owls to our group. The observation was made during daylight hours. We observed one adult and one young Stygian Owl roosting approximately 10 m high. The owls were roosting in the same tree as in previous visits. The adult was identi ed by its dark brown plumage, few light colored spots and bars on the back and scapular feathers, yellow eyes, and distinctive ear-tufts, originating from the center of the forehead, and curved inward. The young owl was identi ed by a signi cant amount of down plumage on the head, lack of completely developed ear-tufts, and ight feathers. Discussion The ecology of the Stygian Owl is one of the least known of all Central America owls (Enriquez et al. 2012). Although the nest was not located, our observation of a chick that had recently left the nest, but may have not attained sustained ight, constitutes the rst con rmed nesting of the Stygian Owl for Guatemala (Eisermann and Avedano 2013). However, previous observations from Los Andes by JLY indicate Stygian Owls have bred there in other years. Available literature from Central and South America indicate the Stygian Owl breeding period could range from December to June and coincide with both dry and wet climatic seasons. The estimated December nesting of the Stygian Owl from Los Andes coincides with the dry sea-

PAGE 18 ISSUE 17 • JUNE 2014 H Historically, in Colombia, the Andean Condor ( Vultur gryphus ) was distributed along the three mountain ranges, the Perij and the Sierra Nevada de Santa Marta (Olivares 1963). However, by the late 1980s their populations had dropped considerably. They had disappeared from the majority of their historic range, and their geographic distribution was restricted to the Sierra Nevada de Santa Marta and Chiles Volcano on the border with Ecuador (Rodrguez et al., 2006, Negret 2001). The Andean Condor is currently listed as an endangered species, and it is believed the the population in Colombia today is comprised on no more than 60 individuals (Renjifo et al. 2002). In an effort to restore the species, the National Institute of Renewable Natural Resources and the Environment (INDERENA), with the support of the Zoological Society of San Diego, began a reintroduction program for the species in 1989. Since then they have released 71 condors in seven release areas along the Colombian Andean Region (Lieberman et al. 1993, Rodriguez et al., 2006).

To help contribute to the knowledge and assessment of the conservation status of the Andean Condor in Colombia, we present information on condor sightings between 2006 and 2014 in the Northeastern Colombian Andes, which is considered to be the principal dispersion corridor for the species in the country (Rodrguez et al. 2006). Sighting information was compiled by Fundacin Neotropical and the environmental group Fauna Libre Colombia. Methods We conducted interviews in local communities in several locations in the Northeastern Colombian Andes to identify areas of frequent condor sightings between 2006 and 2014. We corroborated this information through direct observations made between 0600hrs and 1800 hrs. We record-

Results Through direct observation of native and/or reintroduced condors, we were able to corroborate their presence in 12 locations reported by community members in different parts of the Northeastern Region of the Colombian Andes. Particularly noteworthy is the presence of juveniles in eight of the twelve localities, which is clear evidence of recent reproduction within the population. During the interviews, there were recurrent comments among community members that condor sightings have become more frequent since 2000. Moreover, in most of these places condors had not been seen since the 1950s. Discussion The existence of recent records of Andean Condors of different sexes and ages in several locations in the Northeastern region of the Andes is encouraging news for the conservation of the species in the country. These records highlight the importance of this region as a corridor for Andean Condor populations in three regions that were previously isolated: 1) north (Sierra Nevada

These new records generated several doubts about the causes of this increase in condor sightings: have the condor reintroductions, which began over 20 years ago in the country, contributed to the recovery of the species? Is this a result of re dispersion where existing condors in northern populations ( Sierra Nevada de Santa Marta and the Serrania Perija ) act as a gene pool for other regions of the country? Answering these questions will involve much follow-up work in the eld to gain information on population numbers the structure of local Map 1: Location of recent records for Andean Condor (green dots) and the nuclei of the repopulation efforts (red dots) in the Northeastern Colombian Andes.

This species is possibly one of the least known falcons in the world (Baker 2000).

There are records of Orange-breasted Falcons having been either collected or sighted within the three mountain ranges of Colombia, including from the areas of Tres Esquinas River (Caquet), Puerto Asis (Putumayo), Munchique (Cauca), Puri cation (Tolima), Moscopn River (Cauca), Hope (Magdalena) and the Serrania de la Macarena (Meta) (Hilty and Brown 1986, The Peregrine Fund 2014). This species has been classi ed as Data De cient in the Red Book of Threatened Birds of Colombia (Renjifo et al. 2002) and internationally it is considered Near Threatened. Deforestation and habitat fragmentation are its principal threats (Birdlife International 2012). In Colombia, in 2008, the Reserva Natural de las Aves Halcn Colorado (The Orange-breasted Falcon Natural Reserve) was created by Fundacion ProAves to preserve and investigate this species in the piedmont plains of the country. The Orange-breasted Falcon can be found in various habitats such as lowland forest, savanna edges, and some regions with lower rainfall, as well as on slopes and cliffs in the subtropical mountains where it has been reported to build its nests. This species is uncommon in urban landscapes that have been affected by strong human intervention, occurring in these areas only if there is mature forest coverage which provides habitat suitable in both size and resources (Berry et al., 2010). Though there are no reports so far in the literature of F. deiroleucus in Bogota or its surroundings., on 19 January 2014 around 19:00 hrs, we found an Orange-breasted Falcon which appeared to have been stunned, possibly by a collision that left a small wound on its cere in the Jos Celestino Mutis Botanical Garden in Bogota, The female Orange-breasted Falcon after rescue Carlos Forero – Jos Celestino Mutis Botanical Garden

They gave the falcon a complete physical examination and there were no abnormal ndings. They also took morphometric measurements which indicated that the individual was a female, as she was within the range of size and weight as recorded by Mrquez et al (2005).The falcon was kept under observation overnight. The following day, 20 January, 2014, after feeding it and testing its ying abilities, the falcon was released. On 26 April 2014, during a day of bird watching by the National University of Colombia Ornithology Group, an individual Orange-breasted Falcon was observed passing over the moors (2,610 m) of the Botanical Gardens ying from west to east. This region of the Botanical Gardens is where the highest number of bird species have been recorded during the surveys that we done so far in 2014 (53 species).

Located at 2555 meters above sea level, the Botanical Gardens are located in the heart of the city and contain 19.5 hectares of diverse vegetation including some of the most representative species of the Bogota savannah and Colombian ora. The garden provides resources for many bird-eating species. It is hoe to a large number of small birds, such as the Common Dove ( Zenaida auriculata ), which is a common prey species for the Orange-breasted Falcon (Mrquez 2005). Similar initiatives to those of the Botanical Gardens elsewhere in the city and a signi cant increase in vegetation cover could mean new opportunities for establishment and survival of species such as the Orange-breasted Falcon which have complex ecosystem requirements. The botanical gardens are a haven and place of passage for more than 80 species of resident and migratory birds ( Zerda et al 1992). Studies and efforts to promote awareness of this and other bird species will contribute to our knowledge another step towards the conservation of these species.

It is considered a patriotic emblem in 5 South American nations and serves as an inspiration for sacred myths in several Andean cultures in the region. This species, regarded as “the messenger of the Sun” by some cultures, is listed by IUCN as Near Threatened (NT) on a global scale. In Colombia it is categorized as endangered (EN). (Rodriguez and Orozco 2002, BirdLife International 2013), In Colombia, the Andean Condor once lived along the western, central and eastern cordilleras. Today, it is mainly con ned to a few ancestral strongholds some of which are protected as National Parks, Protected Areas or indigenous reserves.

PAGE 31

WWW.NEOTROPICALRAPTORS.ORG PAGE 29 The Andean Condor has one of the lowest reproductive rates in birds, it lays one egg every two years, is monogamous, and reaches sexual maturity at around 6-7 years of age. These features make this bird very sensitive to anthropogenic disturbance as the species requires a long time to recover individuals within the population. Thus a massive loss of individual Andean Condors could bring the population to a critical state. In 1989 an Andean Condor Reintroduction program began in Colombia through an international cooperative agreement between Fundacin RenaSer, el Instituto Nacional de Recursos Naturales (INDERENA) and The Zoological Society of San Diego. The goal of this effort was to repopulate condors in some moorland and mountain slopes of the Colombian Andes (INDERENA 1990). The San Diego Zoo bred Andean Condors in their facilities located in California. Captive-bred juvenile condors were then sent to Colombia for release in ve core areas where the species once existed and where some wild individuals still remained. This reintroduction project facilitated the study of the behavior of wild individuals and reintroduced birds, and allowed for an estimation of the rate of population recovery. Between 1991 and 1995, biologists monitered 8 condors that had been released in the High Andean Chiles Volcano System. In 1995, monitoring efforts were suspended in this core area due to the likely displacement of the condors to the El ngel Paramo, the Cotacachi and Imbabura Hills and the Cayambe Volcano in northern Ecuador (Barrera & Feliciano, 1994; Foundation RenaSer, 1995).

PAGE 30 ISSUE 17 • JUNE 2014 In 2001, 39 condors were released, each one tted with a wing tag. (Fundacin NEOTROPICAL, 2010). However, no one had been monitoring the condors in the area until 2009 when the Ministry of Environment and Sustainable Development (MADS) signed an agreement with Fundacion NEOTROPICAL to assess the current status of Andean Condor in the reintroduction sites in the High Andean Chiles Volcano System. Considering the importance of understanding the dynamics of the Andean Condor populations in the south of the country, in 2012 and after three years without records, we initiated this study to determine the current population status of this species in the Andes of southern Colombia and northern Ecuador, extending the monitoring and tracking range in the High Andean Chiles Volcano System Methods The research took place in the reintroduction areas of Nario Department, Resguardo Indgena de Chiles in southern Colombia and in La Esperanza, Municipality of Tulcn Parish Tu o, Carchi Province, Ecuador. The High Andean Chiles Volcano System is located 86km southwest of the city of Pasto (Nario Department’s capital), in the geographic coordinates 0 49 ‘N and 77 56’ W. It is located at an altitude extending from 3000 to 4770 masl. The area is composed of high Andean paramo ecosystems and is part of the volcanic complex covering an area of 5,626 hectares. (INGEOMINAS, 2000). The town of La Esperanza is located in Sierra Norte, Ecuador. To the north it borders with Colombia, to the south with the Reserva Ecolgica El ngel, to the west with subtropical lands that reach the Paci c and to the east with the eastern portion of the inter-Andean area of Tulcn. The geographical coordinates of Tu o are 0049’ N and 7751’ W. (Proyecto Pramo Andino, 2004). We collected data in the geographical unit corresponding to the high Andean Chiles Volcano paramo ecosystem during 2012, covering both the summer and winter months. We recorded eld data monthly. (Dry period: January, February, June, July, August and December; Rainy Period: March, April, May, September, October and November). We monitored and tracked individuals ying over the area, in both Colombian and Ecuadorian territories. We also conducted interviews with local community members in both countries. We recorded data from between 3500 and4770 masl covering 5626 hectares of the Chiles Volcano moor or 56.2% (3164 ha) of the monitoring area; and 9000 ha of La Esperanza, Ecuador, or 49.5% (4457 ha) of the monitoring area. During these surveys we took into account certain parameters such as ight paths in the Andean bio-

At two of these sites (La Puerta and Antenna) platforms were built to bait the condors in, thus allowing us to identify reintroduced individuals by way of their wing tags. Data were collected taking into account weather conditions, associated fauna, and behavior of the observed individuals. Behavior consists of a series of continuous events which are identi ed and constitute part of the data collection. (Zerda, 2004). The observation of the ethology of the individuals involved the description of patterns of behavior observed during monitoring which were placed in a behavioral category: ight, feeding, foraging, nesting, perching and interacting with other birds. Results We observed 7 Andean Condors over the year of the study, which took place in the Resguardo Indgena de Chiles (Colombia), La Esperanza and El ngel (Ecuador). Individuals were seen alone, in pairs, in groups of three (a pair and a juvenile female) and in groups of four in ight (a pair, a sub-adult and a juvenile female). We observed the behavior of two condors one adult female and one juvenile male of approximately three years of age, perched and feeding at the bait station platforms. We documented the juvenile male ying alone, unlike a juvenile female of about a year and a half old, which we observed traveling in the company of adults. We were also able to study competition and heirarchical behavior during feeding at the baitedplatform placed at La Puerta. We observed a juvenile Caranculated Caracara ( Phalcoboenus carunculatus ) chasing the juvenile male condor in ight over the platform. The caracara prevented the condor Core release sites since 1989.

Once the food was placed on the platforms (calves and cows that died of natural causes) the caracaras were the rst to arrive and to feed. We recorded up to 10 adult and juvenile P. carunculatus whose presence helped the condors detect the food faster. An adult female condor was the rst to y over the platform at La Puerta and days later she descended to the platform to feed. An adult male was observed feeding and then a juvenile male descended to the platform. Afterwards, the adult caracaras returned to nish eating followed by the juveniles. Discussion The eld observations show that part of the dif culty in determining the population status of the Andean Condor is due to the logistical problems at the time of monitoring a species with a small population size. Human activities and the subsequent changes generated in the ecosystem have led the species to a degree of threat and vulnerability which implies a greater investment of time over greater distances to locate and observe individuals in the eld. According to Hutchinson (1978), population size has often been used as a measure of the health of a species. It is a retrospective tool that indicates the existence of a population change after it has already taken place. Identifying the causes of this change requires not only information on the size of the population and its demographics including data on its composition and internal dynamics. (Temple and Wiens 1989). Climate patterns are critical in determining the characteristics of the vegetation and the presence of wildlife within a given ecosystem. The climatic in uence in the paramo ecosystem is very active, especially in the large diurnal temperature swings and constant humidity. These factors are important for development of the behavior and habitat use of living things. (Hedberg, 1964). Any modi cation of the paramo ecosystem, this species’ habitat, could generate a decline in the health and reproduction of the condor causing the birds to migrate into other regions or even more serious, it could cause the population to become decimated to the point of extinction. Like other species occupying the paramo ecosystem, the Andean Condor plays an important role within the food chain. Thus conservation of this species will contribute to the protection of other species within its range including the Andean bear ( Tremarctos ornaments ), white-tailed deer ( Odocoileus virginianus ), little red brochet deer ( Mazama ru na ), mountain tapir ( Tapirus pinchaque ), and puma ( Puma concolor ) among others. The results of the research conducted within the High Andean Chiles Volcano System demonstrate the need to continue binational efforts

We can infer that the number of individuals observed during the monitoring year is representative of the population of this species in southern Colombia and northern Ecuador and that without community engagement for their protection, condors could disperse from the area or worse, become extinct locally. Currently supported by the Ministry of Environment of Ecuador (MAE) Provincial Directorate of Environment of Carchi and Fundacin NEOTROPICAL Colombia, we continue to make systematic visits to the study area to observe the ethology of the condor in the wild, their movement patterns in response to rural-urban growth, and to conduct environmental education in local communities. These efforts strengthen their commitment to the Andean Codnor and help to generate conservation strategies and respect for the species.

WWW.NEOTROPICALRAPTORS.ORG PAGE 35 Markus Jais has been interested in nature since he was a kid. His main interests are the ecology and conservation of predators like big cats, wolves and large birds of prey, particularly eagles. He runs the www.europeanraptors.org website and is a contributor to www.africanraptors.org. He recently interviewed Thomas Hayes, of The Peregrine Fund, about his work with Buteo ridgwayi in Dominican Republic. Markus Jais: Where does the Ridgway’s Hawk ( Buteo ridgwayi ) occur? Thomas Hayes: The Ridgway’s Hawk is an island endemic which historically has been found throughout the island of Hispaniola and a few surrounding satellite islands. The current distribution is isolated to Los Haitises National Park (LHNP) in eastern Dominican Republic. A small number of additional birds reside in two areas where The Peregrine Fund (TPF) has been conducting experimental releases of the species. MJ : How many Ridgway’s Hawks are alive today in the wild? TH : The current estimated population of Ridgway’s Hawks is roughly 300 individuals. The species is listed as critically endangered making active conservation measures a necessity. Their isolation to a 1,600 km national park leaves them extremely vulnerable to catastrophic events such as hurricanes or disease outbreaks. MJ : What is the preferred habitat for Buteo ridgwayi ? TH : Historically Ridgway’s Hawks have been found in a wide variety of habitats throughout HisCONVERSATIONS FROM THE FIELDBy Markus Jais Adult Buteo ridgwayi The Peregrine Fund

The habitat on this island has been dramatically altered over the last several centuries which leave many questions as to what the ideal habitat for the species is. From our experience they require sections of intact forest for hunting and prefer to nest on forest edges or disturbed forest areas. The species is highly adaptable which makes them a good candidate for conservation activities. MJ : What is the species’ main diet? TH : Ridgway’s Hawks seem to prey on just about anything that is available. Their primary food source is reptiles such as anoles, skinks, and snakes, but they also readily prey on frogs, bats, rats, mice, small birds and even insects. MJ : What are the main threats this species is facing? TH : As with most endangered species, Ridgway’s Hawks are facing several anthropogenic threats. Habitat loss due to agricultural activities and especially clearing forested areas with unontrolled res. In Dominican Republic, as in many countries, raptors are persecuted by locals to protect their chickens and to be used as a food source too. Currently, we are monitoring a large nesting population of Christine Hayes and Thomas Hayes banding and weighing a nestling Ridgway’s Hawk in Los Haitises National Park The Peregrine Fund

PAGE 39

WWW.NEOTROPICALRAPTORS.ORG PAGE 37 Ridgway’s Hawks for infestations by an ectoparasitic y, Philornis pici We have documented these infestations to be lethal on many occasions and have now begun to take proactive measures to treat nestlings. Whether these parasites have increased in numbers due to climate change or habitat alteration is unknown, but they are considered a serious threat to the species. We have also documented many Ridgway’s Hawk nests falling during both the incubation and the nestling periods. Usually, nests which have been built in Hispaniola Royal Palms natural shed their fronds, and these nests have the potential to fall at any time depending on the individual nest tree. An additional threat for the species is that they are now isolated to Los Haitises National Park, and it is not at all protected as one might think for a national park. Thousands of small agricultural plots (conucos) are scattered throughout the park and parts of the forest are burned every year to make room for more conucos. The Dominican government is still trying to gure out how to make LHNP a secure national park and also how to handle the humanitarian problem of either moving existing villages outside the park or cooperating to help them form economies which fall in line with the protection of the national park. MJ : What is the general attitude of the local people towards the Ridgway’s Hawk? TH : The general attitude of most Dominicans towards raptors is to kill them to protect their chickens or for food. You have to understand that the average Dominican family makes very little in the way of income so they are highly dependent on their domestic crops and livestock or poultry for food. The good news is we have found that the people are generally willing to change their attitudes after learning about conservation and in some cases we have provided materials and helped people to build chicken coops to help resolve the con icts with the hawks eating their young chickens. In the areas where we have a real presence such as in the town of Los Limones, the people have begun to embrace the hawk as a treasure and have become an important part of protecting the species. MJ : What are the main goals of your project?

Also, research which helps us understand the species and the effect that our conservation efforts are making on this critically endangered species. MJ : How do you see the future of the Ridgways Hawk? TH : We feel that the Ridgway’s Hawk has a good chance for recovery as long as conservation organizations continue to work with the species. Several of the reasons that the species has suffered such a decline are also reasons why it should be able to be recovered. Ridgway’s Hawks are very adaptable so depending on pristine native habitat is not necessarily an issue. Ridgway’s Hawks are known to be very tame and often nest and hunt in close proximity to humans. This makes persecution of the species a real problem, but for this reason as long as humans are not killing the hawks then habitat close to people is suitable. One possible reason for the species decline is it’s a non-migratory nature. As populations have been wiped out over the last century, they have been unable to become re-established in other areas because the species does not disperse or range from their natal areas. For this reason, the assisted dispersal releases into suitable habitats is essential for creating new self-sustaining populations. Ultimately, education will be an essential conservation activity to help protect the species in the future.
