IMPACT OF HABITAT FRAGMENTATION ON
MIGRATORY SONGBIRDS IN BREEDING AND
WINTERING AREAS
(IMPACTO DE LA FRAGMENTACION DEL
HABITAT EN LAS AREAS REPRODUCTIVAS Y DE
INVERNAMIENTO)

ROBERT A. AsmsIs
Department of Zoology. Conneficu College, New London,
Connecticut, 06320 USA

Severe population declines of migratory songbirds occurred
at several sites in the eastern United States because of
fragmentation ofbrecding habitat. Forest fragmentation leads
to high rates of parasitism by cowbirds and nest predation.
Apparently as a consequence, in the temperate-zone breeding
areas many species of migratory birdsoccurat lowerfrequency
and densities in small patches of forest than in extensive
forests. Comparison of SL John and St. Thomas, two adjacent
islands in the U.S. Virgin Islands, suggest that habitat frag-
mentation may also result in low densities of migratory birds
in wintering areas. Only 12% of St. John is developed and
large areas of continuous forest are protected in Virgin
Islands National Park. In contrast, 62% of St Thomas is
developed, and moist forest is restricted to small remnant
patches. Both the density and species richness of winter
resident warblers were significantly higher in moist foreston
St. John than in similar habitats on St. Thomas. Although
habitat fragmentation may have an adverse impact on win-
tering migrants, it probably has an even greater impact on
many species of tropical residents.

Severos declives en las poblaciones de avyes migratorias
han ocurrido en el este de los EE. UU. debido a las
fragmentacidn del hAbitat reproductivo. La fragmeniaci6n
del bosque induce a una alta taza de parasitismo por Tordos
y depredacida del nido. Como un aparente consecuencia,en
las areas reproductivas de Yonas templadas, muchas especies
de aves migratorias ocurren en menor frecuencia y densidad
en pequefios parchos de bosques que en bosques extensos.

WINTER DISTRIBUTION AND FUTURE
PROSPECTS FOR NEOTROPICAL TERRESTRIAL

We surveyed wintering migrants in 15 terrestrial habitats in
the Bahamas and Greater Antilles. Of the 150species detected,
23% were migrants (74% warblers; Parulinac, Emberizidae).
Migrants constitute an average of 25% (1-71%) of the indi-
vidual birds in terrestrial habitats in the Bahamas and Greater
Antilles, but theirproportions decline southward in theLesser
Antilles. Current estimates show that 21% of the land area
(about 5 million ha) remains in forest on Caribbean and
Bahamian islands. Although reforestation occurs on a few
islands, remnant forest fragments are threatened by man or
natural disturbances. Th us,migran tsrequiring closed-canopy
forest are at greatest risk to habitat loss, whereas early-
successional species are not currently threatened. Policies
that protect mangrove, wet limestone, and montane broadleaf
forests in the Caribbean,and broadleaf coppicein the Bahamas
will benefit migrant and endemic species.

We have monitored birds in the Guinica forest of southeast
Puerto Rico since 1972. This has involved a single line of 16
mist nets for the period of 1973-1992, plus one additional line
during 1972-1980 and 8 additional lines in 1989-1992. Lines
are operated from dawn to dusk for 3 consecutive days in
January or February of each year. Such long-term studies
provide insights unattainable through short-term studies, in
this case long-term declines in populations of winter resident
birds and how drought affects resident birds. The decline of
winter resident birds evident during 1972-1988 is described,
along with the partial recovery during 1989-1992. We also
show how drought affects nectar and fruit eating birds more
rapidly that it does insectivores. Information on survival and
longevity rates of birds available from long-term studies is
also presented.

We used mist nets and point counts to sample bird popula-
tions in 61 sites in Belize during January-March of 1987-
1991. Sites were classified as forest, second growth, woody
agricultural crops (citrus, mango, cacao, and cashew), or
non-woody agricultural crops (rice and sugar cane). We
evaluated patterns of occurrence of wintering temperate
migrant bird species in these habitats. Mist net captures of 22
of 31 migrant species differed significantly among habitats,
Of these, 13 species were captured more frequently in the
agricultural habitats. American Redstart (Setophaga ruicilla),
Black-and-white Warbler (Mniotilta varia), and Magnolia
Warbler (Dendroica magnolia) were among the species
captured most frequently in woody agricultural habitats:
captures of Common Yellowthroat (Geothlypis trichas), In-
digo Bunting (Passerina cyanea), and Northern (Icterus
galbula) and Orchard orioles (I. spurianus) were highest in
the non-woody agricultural sites. We relate these occurrence
patterns to trends in breeding populations in North America.
While count data provide a wide picture of winter habilat
distribution of migrants, more intensive work is necessary to
assess temporal and geographic variation of migrant bird use
of agricultural habitats.

Although Canadians have long been interested in neotropical
ecosystems, declines in several Neartic breeding birds have
recently heightened Canadian interest in their conservation.
Canadian efforts haveincludedbanding studiesby the Ottawa
Banding Group on Andros Island, habitat studies by the
Canadian Nature Federation in a park in the Dominican
Republic, and several surveys by Canadian Wildlife Service
officials. A recent program in Cuba emphasizes cooperative
research and training. A two year banding project of the Latin
America Program of the Canadian Wildlife Service, the Long
Point Bird Observatory, and the Laboratorio de Aves
Migratorias in the Academia de Ciencias de Cuba (1988-
1989) has been followed by a five-year survey of Neartic
migrant and neotropical birds wintering in Cuban forest
ecosystems. This project is designated to help Cuban orni-
thologists participate more fully in the international orni-
thological community and we hope that it will lead to more
cooperative efforts and continuing dialog between Canadian
and Cuban scientists.

Avian m ixed-species flocks are a cosmopolitan phenomenon
occurring in various degrees of complexity in different bio-
geographical regions of the world. Since October, 1990, we
have studied their ecology at the Maricao Forest in the
Cordillera Cen tral of west-central Puerto Rico. Five routes in
upper cordillera forest and mixed upper cordillera-plantation
forest were regularly surveyed. Data on frequency of flocks,
species composition, habitat use, foraging, and interspecific
behavior were recorded. Preliminary results suggest the
Puerto Rican Tanager (Nesospingus speculiferus) (PRT)
appears to be the primary nucleus species. A total of 20
species were recorded participating in flocks. Flocks were
observed to contain as many as 12 species and as few as 1.
PRT use distinctive calls to congregate species as well as to
disperse theflock when hawks (Buteospp.) are in the vicinity.
A total of five species of migratory warblers were regularly
associated with the flocks. Of these, Black-throated Blue
Warblers (Dendroica caerulescens) and Black-and-white
Warblers (Mniotilta varia) were most common in the flocks.
Several aspects of habitat use and species interactions will be
discussed.

Birds that migrate among Western Hemisphere countries are
a shared natural resource. Their conservation requires co-
operative programs that are coordinated by all nations used
by these species. Partners in Flight- Aves de las Amricas is
a program created to meet this need for 250 species of
migratory landbirds that nestin the United States and Canada
and spend the non-breeding season in the Caribbean, Mexico,
Central America, and South America. U. S. federal and state
agencies, NGO's, universities, philanthropic groups, and
industry have come together to support the Partners in Flight
initiative. By working cooperatively, these groups reduce
program overlap and maximize financial resources available
for migratory bird conservation, and improved communica-
tions open doors to previously unrealized partnerships. The
cooperative nature of the Partners in Flight program has also
resulted in unprecedented public and political recognition, a
key to success. The United States component of Partners in
Flight has developed and stabilized over the last 18 months,
providing a solid base of support for complementary efforts
in the Caribbean.

As ornithologists faced with declining bird populations in
deteriorating habitats and limited time and financial re-
sources, we are obligated to direct research towards objec-
tives that can assist in achieving conservation needs. The link
between research and conservation, between knowledge and
land use policy, inevitably involves commmunications,money,
and politics. Partners in Flight encourages formation of a
West Indian working group for conservation of neotropical
migratory birds through habitat conservation that will in turn
benefit all the elements of regional biological diversity. The
goals of this working group can include: 1) increased com-
munication among scientists, conservationists, and policy
makers: 2) outreach to increase public awareness of threats to
biodiversity; 3) connections to United Stales-based parties to
Partners in Flight, potentially accompanied by a flow of
resources to the West Indies: and, hopefully, 4) increased
protection of habitat for migrants, endemic birds, and other
organisms throughout theregion. Eslablishmentofa bureau-
cracy is a necessary evil if these objectives are to beachieved.
Hints from involvement of The Nature Conservancy and the
growth of the Southeastern working group may be useful in
the early stages of a West Indian working group.

Since colonization by Europeans. the Florida Keys have
undergone two periods of widespread deforestation. The
first, in the late 1800s was primarily as aresult of conversion
of forested land to agriculture. Following the demise of the
agricultural industry in the early 1900s, the forests went
through a recovery phase.'The second period of deforestation
occurred from the mid 1900s to thepresent asaresult of forest
clearing for human settlement and development of a tourist
industry. In the upper keys, deforestation has resulted in the
loss of 45-75% of the historic upland forest acreage on keys
tha tare accesi ble by road. Keys that are notaccessibleby road
have lost less than 5% of their forested area. We found that
fourspecies of forest breeding birds in the Keys were sensitive
to the size of forest tracts. The minimum area requirements
were 2.3 ha for White-eyed Vireo (Vireo griseus), 3.5 ha for
the Northern Flicker (Colaptes auratus), 7.5 ha for Yellow-
Page 8


billed Cuckoo (Coccyzus anericanus), and 12.8 ha for the
Mangrove Cuckoo (Coccy:us min or). In 1991. in the upper
Keys. upland forest > 12.5 ha. comprised only 3% of the
number of forests and 67% of the forested area compared to
30% of the forests and 97% of the forested area in the historic
condition. Habitat fragmentation has probably had immense
impacts on the population and distribution of these four
species in the upper Florida Keys.

Populations of three primate species currently inhabit south-
western Puerto Rico. Two of these species are primarily in the
Sierra Bermeja and adjacent areas, whereas the third species
is widely distributed. Population densities of species I and 2
are relatively stable and are estimated at 2.2 individuals/km2.
In contrast, a 1990 census revealed a much higher, and
increasing, density of both resident and migratory popula-
tions of species 3. Although the impacts of species I and2 on
native biota is at most incidental, damage caused by species
3 is widespread and deliberate, including destruction of

The conservation of Antigua and Barbuda's remaining eco-
systems has become a priority of local environmental orga-
nizations. The push to protect the North Sound area is a fine
example. The North Sound area of Antigua is known for its
concentrations of wildlife, open spaces, natural beauty, and
recreational values. The government has been petitioned to
designate this unique area as a Sanctuary/Reserve. There are
also ongoing educational programs and community meetings,
to create awareness among the people whose actions and
activities would affect (positively or negatively) this area.
Environmental groups in Antigua and Barbuda am develop-
ing new approaches to the conservation of many of these
areas. The idea of Land Trust and assessment are currently
being explored for local use. But the single biggest obstacle
to the implementation of conservation projects in the island
is financing. With a couple of well-developed and -funded
projects much more can be achieved, and in a shorter space
of time.

A POPULATION ESTIMATE OF WHITE-

Mound Trail, Tavernier, Florida 33070 USA

During the 1991 nesting season, we developed a methodol-
ogy for estimating the population of White-crowned Pigeons
(Coluwmba leucocephala) nesting on mangrove keys in Florida
Bay. Remotely collected data from past studies of the pi-
geons' nesting ecology showed the average arrival time at the
nest for males to replace females was 09:49 (08:13-11:25 =
95% C.I., N = 158). We used the early part of the nesting
season (9-27 June) to develop a relationship between the
number of birds flying onto akey (between 08:13 and 11:25)
and the total number of nests on that key. We found the
highest correlation for the period 08:20 to 10:30 (r= 0.877,
P < 0.001), and developed a regression equation: (number of
nests) =0.83 (numberof incoming birds from 08:20-10:30)
- 8.10; (n = 14, F = 4036.P < 0.0001). From 15 July to 23
August, the peak period of nesting activity, we thencensused
incoming birds on dithe43 keys we felt had the highest nesting
populationand used the above regression equation to estimate
the total nesting population. Nesting population on the 43
keys censused was 3,313-6,432 nests (95 % C.L). We con-
ducted total.nest counts in conjunction with censuses on 6 of
the 43 keys and found no significant difference between the
actual and predicted numberof nests (paired t-test = 0.28,
P = 0.788), Using data from past censuses of an additional 48
smaller keys in Florida Bay, we estimated the total nesting
population to be 5,049 nests.

En este trabajo preliminar se desglosan en sus diferentes
componentes el patron de cortejo y c6pula de 4 parejas
cautivas de Paloma Sabanera (Columba inornata weinwrei)
que se observaron copulando en 27 ocasiones. Se observaron
los siguientes componentes en la conducata pre-copulatrfz
vocalizaci6n, acicalamiento de las plumas del ala, el sacudirse
y cabecdo exagerado. Mientras queen el patrdn copulatrfz se
encontraron el saltar sobre la hembra, cabecdo exagerado y

no resulto ser un patron estereotipado; se notaron variacidnes
a nivel de las diferentes parejas. Se observaron copulaciones
desde las 7:31 hasta las 18:00, habiendo mayor frecuencia de
esta actividad de 8:31 a 9:30 y 17:31 a 18:00. El tiempo que

forma do facilitaci6n social para reducir episodios de
agresividad o el resultado de hembras sobre exitadas.

In this preliminary work, we classify the different com-
ponents of courtship and copulation in 4 captive pairs of
Puerto Rican Plain Pigeons (Columba Inornata wetmorei)
that were observed copulating on 27 occasions. The following
components of the precopulation behavior were observed:
vocalization, wing feather preening, and exaggerated shak-
ing and nodding. In the copulation behavior it was found that
jumping over the female, nodding and wing flapping were
Page 11







used to achieve cloacal contacL The pre-copulation behavior
was ot a fixed pattern, since variation existed among pairs.
Copulations were observed from 7:31 lo 18:00, with a higher
frequency from 8:31 to9:30 and 17:31 to 18:00. Copulation
lakes from S to 45 seconds (mean = 15.81). Females mounting
males were observed after copulation. It is inferred that this
behavioral pattern is a form of social facilitation to reduce
violent episodes or the result of over excited females.

THE HAIRY WOODPECKER IN THE BAHAMAS
(EL CARPINTERO SERRANERO EN LAS BAHAMAS)

JEROME A. JACKSON
Departini of Biological Sciences, Mississippi State University.
Mississippi State, Mississippi 39762 USA

The Hairy Woodpecker, Picoldes villosus, occurs through
forested North America, south in mountains to Panama, and
to Abaco, Andros, Grand Bahama, Mores Island, and New
Providence in the Bahamas. It likely arrived in the Bahamas
during glacial maxima and has remained isolated since. Two
subspecies are recognized from the Bahamas, where popu-
lations have more white spotting on wing feathers than do
birds from adjacent Floridapopulations,considerablevariation
in the extent of white on the face, and some tendency towards
barring on the back. Some plumage characteristics resemble
featuresof theRed-cockaded Woodpecker (P. borealis) of the
southeastern United States. Sexes differ significantly in bill
dimensions, but there is less size variation between sexes in
the Bahamas than in mainland populations. Bahama Hairy
Woodpeckers are the most isolated of the species and miul-
tivariate analysis of plumage color pattern and mensural
characters suggests considerable divergence from mainland
birds. Hairy Woodpeckers in tle Bahamas seem limited to the
heavily exploited pine forests and may be threatened by

CRITICAL STATUS OF THE
WHITE-BREASTED THRASHER
(CONDICION CRITICA DEL
ZORZAL DE PECHO BLANCO)

LYNDoN JoIN
Forestry Department. Ministry of Agriculture, Castries, St. Lucia

In 1987 (14 June 14 August), an expedition was undertaken
in the northeastern region of SL Lucia. This program was
jointly sponsored by the University of East Anglia (U. E. A.)
and the International Council for Bird Preservation. The
primary objective of the project was to study the six endemic
species and subspecies of the birds in this region. Special
emphasis was placed on the critically endangered SL Lucia
While-breasted Thrasher (Ranphocinclus brachyurus), lo-
cally called "Gorge Blanc". A census was completed and its
habitat requirements and threats to its population assessed.
This species only occurs on one other island, Martinique,
where the nominate subspecies is restricted to the Carevalle
Peninsula. The estimated population in 1987 was 40 pairs for
Martinique (Benito Espinal, pers.comm.). A maximum of 58
pairs of White-breasted Thrashers was found for St. Lucia.
Other species noted were the Antillean House-Wren (Tro-
glodytes martinicensis), the St. Lucia Oriole (Icterus
laudabilis). the St. Lucia Black Finch (Melanospiza
fichardsoni) and St. Lucia Nightjar (Caprimulgus oaiosus).
From 22 April -12 June 1992. the Forestry Department, with
the assistance of a graduate of the Durrel Institute of Con-
servation and Ecology (D.LC.E), completed a census of the
White-breasted Thrasher in northeastern St. Lucia. Many of
El Pilirre 5(3)


the former activities had proceeded unchecked from the last
census with habitat destruction notably caused by squatting
and shifting cultivation. A total of 81 birds was noted from
this census. This species is restricted largely to the riverine
vegetation and conservation measures are urgently needed to
protect the remaining habitat

Forest birds inhabiting hurricane-prone islands have evolved
reproductive strategies to re-establish post-disturbance
populations. Ten Pearly-eyed thrasher (Margaropsfuscatus)
breeding seasons (1979-1988) prior to Hurricane Hugo (18
September 1989) wer compared to the firsttwo post-hurricane
(1990-1991) seasons to determine which reproductive pa-
rameters were adjusted in response to post-disturbance re-
source constraints. The average 7 months (January-July)

months (September 1990 to early August 1991).The number

but significantly higher in 1991 than during the 10 year pre-
disturbance period. Clutch size did not vary significantly in
1990 from the pro-disturbance season, but was significantly
smaller in .1991 than in the pre-hurricane period. Hatching
and fledging success were similar among pre and post-
disturbance seasons. Post-disturbance point count censuses
of singing birds showed that the reproductive cycles of other
forest birds were synchronized with that of the thrasher
following Hugo.

There are considerable differences in the nest and egg
descriptions of the Stripe-headedTanager (Spindalls zena) in
Puerto Rico (Danforth 1936, Biaggi 1983, Raffaele 1990). In
15 nests studied in localities in the Carite Forest and the Tres
Caminos rural sector in Barranquilas, I found variability
among the vegetation used for nesting and among the nests
and eggs. Nests were found in 10 species of trees at a mean
height of 8.5 m. The Stripe-headed Tanager nest varies from
shallow cup-shaped simple structures (66%) to massive and
deep nests (33%). The former are constructed with twigs on
the base. with vines covering the external surface, and vines
and thin fibers lining the interior. The massive nests are built
with twigs,vines,epiphyteroots. vegetal wbol, and occasion-
ally grass on the external part. The interior is lined with thin
fibers. The mean size of 16 eggs was 23.7 0.27 (S.D,) mm
by 17.3 0.31 mm, a little smaller than those described by
Biaggi. They vary in shape from elliptic to subelliptic.
General coloration ranges from white to bluish, and the eggs
are covered by spots that vary in coloration from a rusty tone
to a chocolate, almost black. Various hypotheses are pre-
senled to explain this variation phenomena.

ondary wet forest and fragmented secondary moist forest in
rural areas of eastern Puerto Rico. Six paired censuses were

number of owl responses, cloud cover, wind speed, moon
phase, and number of cars passing during 5-min stops at 60
locations. Owls responded in similar numbers (P > 0.05) in
both habitat types. Also, we detected no association with
cloud cover, wind speed, moon phase, or cars on number of
owls censused. We believe that Puerto Rican Screech-Owls
are not adversely affected by the reduction of continuous
forest habitat to a patchy habitat. We suggest that the owl
could be successfully restored to former ranges where frag-
mented forests exist, if suitable nesting cavities and food
resources are available.

William T. March observed and collected birds in Jamaica for
several years in the 1860s. Many of his specimens were sent
to Spencer Baird at the Smithsonian Institution. Others were
given or sold to Henry Bryant. and came to the National
Museum later with the Bryant collection. A few specimens
were sent to Dublin, Ireland, and it is likely that others went
to other institutions. March published a report about his
collection activities in 1863, but information on material
collected later apparently has never been published. The
USNM received more than 1,100 specimens taken by March,
including many sets of eggs. Among material never reported
is the only specimen of the Orinoco Goose (Neochenjubata)
from Jamaica, the Caribbean and North America, the last

IS THE PALM CROW (CORVUS PALMARUM)

Palm Crows are found in Hispaniola and Cuba. In the latter,
they are rare, found only in specific mountain areas in
Camagiley Province. A colony at Pinardel Rio Province has
not been seen recently and is possibly extinct. In Hispaniola,
it is not uncommon in widely scattered areas. Palm Crows
have been variously described as separate species, or sub-
species of Corvus palmarum, or as a monotypic species.
Specimens in most museums are scarce, making studies
difficulL Jobnson (Biosystematics ofAmerican Crows, 1961)
reported, as we do, similar morphology for the two island
populations, with a few differences. We both found Cuban
birds with slightly longer tarsi, and Hispaniolan crows had
longerbills. Wing and tail were longer in Hispaniola: this not
reported by Johnson. The differences in vocalization were
striking. In Cuba, calls include hoarse, grating, rising and
falling slurs,of 0.5 sec. length, including many harmonics. In
Hispaniola, phrases are shorter, 0.3 sec., also rising and
falling pitch, but more staccato, oscillatory phrases, with few
harmonics. Recordings and sonograms will be presented.

The Mexican Crow Corvus imparatus was recently divided
into two species, based on vocalization differences. Our
findings here lead us to suggest Corvus palmarunm as the
Hispaniolan Palm Crow, and Carvus minutus as the Cuban
Palm Crow.

In May and early June of 1991, we inventoried the nesting sea
birds of the;175 sq. mile Exuma Land and Sea Park in the
Bahamas. We recorded 10 nesting and probable nesting
species and'4 migrants and visitors. Two species (Puffinus
therminieri, Sterna sandvicensis) were not previously known
to nest in the Exuma chain and Laras articilla has expanded
its range southward in the island chain. Several unreported
nesting seabird colonies were discovered. The gulls and terns
were in the early stages of colony establishment during our
visit, so maximum colony size cannot be estimated for most
of these species. In comparison to the reported population


Page 16


size for the various species nesting in the Bahamas and the
Caribbean it is clear from our brief survey that the seabird
colonies in the Exumas are significant. Minimal colony size
for each confirmed nesting specie in as follows: Puffinus
Iherminieri 500 (1,000-3.000 maximum) pairs: Phaethan
lepturus- 30 (100 maximum) pairs; Larus atridilla 50pairs
Sterna daugalifi 50 pairs: Sterna fuscata 2,000 pairs.
Sterna alblfrons 25 pairs: Sterna sandvicensis 10 pairs;
Anous stolidus 2,000 pairs.

PROGRESS ON THE SOCIETY'S 1993 MEETING
IN CUBA

Arrangements for next year's meeting of the SCO at the
Cienaga de Zapata, Cuba, are progessing well. Hiram
Gonzalez has been named Chairman of tie Local Committee,
and Daysi Rodriguez is the Secretary. The local committee is
arranging for field trips in and around the Cienaga de ZapaLa.
Further in formation on the meeting and a tourpackage will be
provided in the next issue of the bulletin.



REPORT OF THE PSITIACINE WORKING

El Pitirm 5(3)







Parrot Working Group (Continued)
deuce with members of the Working Group. The plan for a
status report of the West Indian psilacine fauna prepared by
the local residents did not fare well. I received information
only from correspondents in the Bahama Islands and
Dominica. I plan to harass the Working Group members into
fulfilling their commitments until we compile enough infor-
mation to produce a meaningful document.
Most of 1992. however, was spent preparing the two-part
workshop on parrot conservation which was part of the
Society's annual meeting, held in Puerto Rico from 31 July
to 5 August 1992. A lota] of 50 individuals, representing
academic. non-government organizations, and government
institutions,participated in the workshop.lThe Bahama Islands,
Cayman Islands. Cuba, Jamaica, Dominican Republic, Puerto
Rico, SL Thomas (U.S. Virgin Islands), St. Lucia, Trinidad,
Canada, United States, Mexico, Venezuela, and Brazil were
represented. The first part of the workshop was a special
symposium on parrot conservation held on Tuesday, 4 Au-
gust, at El Convento Hotel in Old San Juan. A total of 11
papers were presented on Caribbean and South American
psittacines.
The second part of the workshop was an all-day practical
workshop held at the Caribbean National Forest on
Wednesday, 5 August. Several presentations on psiltacine
census methods, managementofbreeding populations,habitat
management, and forest planning were included. Addition-
ally, a two-hour field demonstration in the western section of
the Forest was conducted in which participants were able to
observe the use of tools, safety techniques for climbing trees,
observation blinds, and methods of improving natural cavi-
ties. Afterwards, atypical Puerto Rican luncheon wasprepared
for participants at La Mina House, adjacent to the captive
facility for the endangered Puerto Rican Parrot. The aviary
section of the workshop had tobe shortened because of severe
weather.
Because of the length of the workshop, we were forced to
delay the meeting of the Working Group. However, I informed
all Group members of my intention to publish the proceed-
ings of the workshop. By mail, I will provide all the speakers
who presented papers with the deadline and format for
submitting either an extended abstract or a complete manu-
script. A manuscript will also be prepared on the material
presented in the practical demonstrations. The publication
will probably be a cooperative effort of the Society of
Caribbean Ornithology, U.S. Fish and Wildlife Service, and
Institute of Tropical Forestry (U.S. Forest Service). I hope to
have the publication ready by next year's Society meeting in
Cuba-
Finally, after consulting with our Cuban colleagues, we
agreed that there will possibly be a half-day workshop on
psittacines during the Society's 1993 annual meeting in
Cuba, More information on this workshop will follow.

REQUEST FOR ASSISTANCE

The West Indian island of Dominica is home to two endan-
gered psittacines, the Imperial Parrot and the Red-necked
Parmr. Recent conservation efforts have been successful in
increasing the Red-necked Parrot population to about 500
individuals. However, the increased population is now pos-
ing a threat to the'citrus crop in Dominica. Anyone with
experience with or ideas on how to deal with parrot "depre-
dations" on citrus crops is asked to immediately contact Mr.
Felix Gregoire. Acting Permanent Secretary, Ministry of

OBSERVATIONS OF BLUE AND RED CATTLE Ecarts wN Tint
WEST INDIES

Several reports have been received of Cattle Egrets in the
West Indies marked on the wings with light blue orred. These
birds were intentionally marked with dye as part of a study of
their movements among islands. Dr. Joe L. Corn of the
University of Georgia is conducting a study of an introduced
disease-carrying tick which may be dispersed through egret
hosts. In 1991, Dr. Corn dyed egrets on Antigua light blue,
and red on another island. He has received sighting reports
from several islands, and even as far north as Florida. If you
have observed such color marked birds, please contact Dr.
Corn with full information at

IN MEMORY OF JACQUELINE "JILL" WEECH


ROSEMARtM S. GNAM

It is with much sadness that I inform Society members of the death of fellow SCO member, Jacqueline "Jill" Weech of
Abaco, Bahama Islands. Many of you had met Jill at our annual meetings in St. Lucia and San Juan.
Jill died as a result of a tragic boating accident at the end of September 1992. The exact details of the accident remain
unknown. The Society wishes to express its condolences to Jill's mother, Rose Weech. and her family during this
extremely difficult time.
Since 1988, Jill was employed as a Forestry Technician in the Bahamian Department of Lands and Surveys. She
received her Bachelor of Science degree in plant sciences from Tuskegee University. During her tenure with the Forestry
Section, she moved from Nassau to Abaco, which became her home. In the summer of 1990, Jill completed the conser-
vation training program at the National Zoo's Research and Conservation Center.Front Royal, Virginia. Jill was respon-
sible for the environmental education program in Abaco's schools and assisted Forestry Officers and visiting researchers
in the field. She helped found "Friends of the Abaco Parrot" a grassroots conservation group.
My first impression of Jill was a soft-spoken, smiling, Bahama Parrot T-shirt-clad, young woman who wanted to help
count parrots during our 1989 parrot survey. She was very enthusiastic and optimistic about conservation efforts for the
parrot. Every field researcher hopes of working with just such an individual and. indeed, I consider myself extremely
fortunate to have had her as an associate during our years of fieldwork. I learned much from Jill. She helped me see the
Bahama Parrot not only as a research topic, but as an invaluable part of a Bahamian's natural heritage, worthy of all of
our conservation efforts. Individuals like Jill made my work with the Bahama Parrot possible.
Jill became active in the Society of Caribbean Ornithology in 1991 and presented her first paper, "Conservation on
Abaco Islands," at the 1992 meeting in San Juan. She hoped to enroll in graduate school next year and pursue research
on Abaco's birds. Birds of special interest to her were Bahama Swallows, migrating warblers, and Hairy Woodpeckers.
She had vowed to give a paper on her "own research results" at the next SCO meeting in Cuba.
Jill was totally committed to ornithology and conservation in the Bahamas. Our last conversation centered on Jill's
efforts to distribute the new Bahama Parrot coloring book and my review of a project proposal that she sent me. After
talking to Jill, I always felt optimistic. She was a badly needed "breath of fresh air" to a sometimes frustrated, desk-
bound field biologist.
There are no publications to list here for Jill Weech, nonetheless, she contributed to Caribbean ornithology. Those of
us who had the opportunity to interact with her can not help but feel obligated to continue her commitment. It is indi-
viduals like Jill Weech who will help the Society of Caribbean Ornithology achieve its goals. She believed in the Society
and her hopes are our hopes. I can only wish that her dream of an Abaco parrot reserve will become a reality sometime
soon.
Jill Weech will be missed. With her passing, the Society has lost a devoted colleague, some of us a dear friend, and
the Bahama Islands a bright hope for the future. A memorial service is planned by her family for next year.
