VAGRANT WHITE STORK CICONIA CICONIA (AVES: CICONIIDAE) FOUND IN ANTIGUA:
A FIRST RECORD FOR THE WEST INDIES

NATHAN P. GRICKS
P.O. Box 672, St. John's, Antigua, West Indies


At 17:00 hr on 14 August 1993, I was scanning through
waders on an open area of mud adjacent to mangroves at
Cook's Dump, outside St. John's, Antigua, when I saw an
adult White Stork (Ciconia ciconia) about 300 m from me. I
immediately informed my companions, who also watched
the bird. The stork stood close to a much smaller Great Egret
(Casmerodius albus). I approached and managed to take two
photographs of the stork before it flew several meters away.
It fed in small rills on the open mud, possibly on crabs. The
stork's plumage appeared in good condition and the bird
displayed no leg rings or wing tags. It was present when we
left 40 minutes later, but it was not there the next morning and
subsequently could not be found.
An Old World species, the White Stork occurs widely in
the Palearctic region and tropical Africa. A small population
breeds in South Africa, but the species summers and pri-
marily breeds in northern continental Europe and central


Asia, to where it migrates in long flights. In Africa, it feeds
in the sub-Saharan savannah grasslands, often in large
numbers, whereas in the breeding region it seeks out mead-
ows and marshes, frequently close to human habitation. The
species faces a long-term threat from adverse changes in
land-use and agricultural methods, as well as from pest
control which kills one of its main prey items, the locust.
Intriguingly, a 'stork' was observed in Barbuda previous to
my sighting in Antigua. However, the two observers did not
get good views and dismissed it as possibly a Wood Stork
(Mycteria americana), itself a vagrant in the region.
The White Stork has not been previously recorded in the
West Indies, nor other parts of the Americas. It is possible that
the individual is a first for the New World. The bird was likely
blown off-course during migration, as a ship-assisted pas-
sage is most improbable. For all those who saw the bird, it was
a stunning discovery!

Pampero Mayor Puffinus gravis.-De acuerdo a Raffaele
(1990), hay un informed de Pampero Mayor cerca de Puerto
Rico y otro de un individuo varado en la Isla de Culebra. El
22 de junio de 1992, el Sr. Manuel Corbet encontr6 un
PapmeroMayormuertoenlasPlayaLas Ochentade Humacao.
Las medidas de este espdcimen son la siguientes: longitud
total, 456 mm; pico expuesto, 44.5 mm, pico desde la part
anterior de los orificios nasales, 31.4 mm; arco del ala, 308
mm; y tarso 57.4 mm. El esp6cimen, provisto por Corbet,
corrobora la presencia del Pampero Mayor en Puerto Rico.

Pigalo PomarinoStercorariuspomarinus.-De acuerdo con
Raffaele (1990), el Pagalo Pomarino es un visitante irregular
de las aguas lejanas a las costas de Puerto Rico, aunque se
acerca a estas luego de tormentas. Bond (1981) indica que el
ave se aventura ocasionalmente al Caribe de octubre a abril.
El colega Jose Col6n, me hizo llegar un espdcimen en
contrado en laLaguna de Pifiones el 27 de diciembre de 1990
por Cindy Gin6s. El ave tiene las siguientes medidas: largo
total, 56.2 cm; pico expuesto, 39.1 mm; pico desde orificios
nasales, 16.5 mm; arco del ala, 34.4 cm; y tarso, 54.3 mm. El
esp6cimen mencionado valida los informes hipot6ticos de
esta especie en Puerto Rico.

Juliin Chivi Gargantiamarillo Vireo flavifrons.-De
acuerdo con Raffaele (1990), hay dos avistamientos del
Julian Chivi Gargantiamarillo para Puerto Rico y uno para la
Isla de Vieques. El iltimo es possible que se refiera al
avistamiento hecho por Williams y Williams (1985) el 18 de
diciembre de 1984 en Play Roja, Vieques. El 31 de octubre de
1992, el segundo autor observ6 y fotografi6 a una de estas
aves en los manglares del Bosque Estatal de Aguirre. Se
observ6 al ave en varias ocasiones ingerir frutas de
Laguncularia racemosa. De ser vilidos los informes
anteriores, a este, se infiere entonces que esta ave es un raro
visitante otofial e internal para Puerto Rico. Bond (1981)
consider a la especie como un raro resident internal de
Cuba, Jamaica, San Vincente y Granada desde agosto 31
hasta el 8 de mayo. La presencia de esta ave en Cuba, Jamaica
y Puerto Rico permit postular el que el ave haya pasado
desapercibida en la Espafiiola.

HABITAT USE BY NORTH AMERICAN
LANDBIRD MIGRANTS ON ST. CROIX, U.S.
VIRGIN ISLANDS
FRED W. SLADEN
P. O. Box 706, New London, NH 03257, USA

Forty-seven species of North American landbird migrants
were observed on St. Croix from September 1981 to Novem-
ber 1988. Observations were made at random over the entire
island throughout the seven years. The occurrence of landbird
migrants was recorded for each of the major habitat types on
the island. Over 50% of the species were found using no more
than 3 types of habitat and more than half of these species
were found in only a single habitat type. Species density was
highest for mangrove forest, littoral forest, and wetlands, and
was lowest for open habitat, urban habitat, and dry forest.

THE PUERTO RICAN PARROT: ITS POTENTIAL
AS AN ENVIRONMENTAL EDUCATION TOOL
JAFET VILEz VALENTfN AND FRANCISco J. VILELLA
U. S. Fish and Wildlife Service, Puerto Rican Parrot Field
Office, P. 0. Box 1000, Palmer, Puerto Rico 00773

Recently, several education programs in the Lesser Antilles
aimed at promoting the conservation of endemic West Indian
amazon species (e.g., Amazona versicolor) have met with
much success. Unfortunately, although the Puerto Rican
Parrot (Amazona vittata) is the most studied and at present
most intensively managed of all Caribbean parrots, little
awareness exists among the public in Puerto Rico of its
present status and of these restoration efforts. To the environ-
mental community, its use as a symbol for conservation and
education has been ignored. We have begun a project
employing strategies proven in other Caribbean islands for
promoting the conservation of our endemic parrot and, through
it, all of Puerto Rico's natural resources.. We aim to work


intensively with schools from the different communities
adjacent to the Caribbean National Forest, an area of montane
rainforests in eastern Puerto Rico and home to the last
population of parrots. Other strategies will be used to reach
the publicat large. We will present preliminary results on the
materials and methods used, as well as the response these
have generated among the Puerto Rican public.

ROLE-CALL FOR INSULAR AVIAN
EXTINCTIONS IN THE WEST INDIES
ROBERT L. NORTON
961 Clopper Road, B-1, Gathersburg, Maryland 20878, USA

Extinctions (e.g., Grand Cayman Thrush Turduscaymanensis)
or extirpations (e.g., Puerto Rican Screech-Owl Otus nudipes
newtoni from St. John, Virgin Islands, and Puerto Rican
Parrot Amazona vittata gracilis from Culebra Island) of
forest-dwelling species occurred on small islands of the West
Indies primarily as a result of forest fragmentation or habitat
loss associated with colonial plantocracies. Other extinctions
of insular species in the Lesser Antilles forced by similar
processes of unchecked forest depletion and fragmentation
are in progress. A review of the literature indicates that the
possibility of another 21 species of birds becoming extinct in
the Lesser Antilles is very real. The potential causes are 1)

habitat degradation or manipulation, 2) introduced predators,
3) hunting, and/or 4) random climatic events. The case of the
Puerto Rican Bullfinch (Loxigilla portoricensis grandis) of
St. Kitts, last seen in 1929, is used to illustrate extinction
pathways. Since the precise cause of the bullfinch extinction
it is not clear, possible scenarios may illuminate pathways of
equally poorly known forest birds of the region. As more
species are erected from complex super-species groups in a
region of high endemism, the potential for greater extinction
rates is considered. Conservation and restoration of insular
habitats will be essential during the latter part of this century
if preservation of biological diversity is to be an international
goal in the next century.

FEEDING BEHAVIOR OF WHITE-CROWNED
PIGEON NESTLINGS IN RELATION TO DIET,
HATCHING SEQUENCE, AND HATCHING
PATTERN
REED BOWMAN
Department of Biology, University of South Florida
Tampa, Florida 33620, USA

Selection for asynchronous hatching in White-crowned Pi-
geons (Columba leucocephala) may occur because of high
rates ofpredation during the incubation period. This hatching
pattern leads to nestling size asymmetries that, in the Florida
Keys, result in decreased survival of last-hatched nestlings
when food is limited, and lower fledgling masses when food
is not limited. As nestlings can be readily distinguished by
their size differences, parents may respond by selectively
feeding the smaller nestling. I observed nestling feeding
behavior at 69 natural asynchronous and experimentally-
synchronized nests during and after food limitation. Larger
chicks from both asynchronous and synchronous broods
received more feeds per hour, more pumps per feed, and fed
longer than their smaller siblings when food was limited.
Feeding behavior did not differ when food was not limited,
but larger nestlings continued to receive more food. During
food limitation, smaller nestlings begged more than their
siblings, but a smaller proportion of those begs resulted in
feedings. After food limitation, no difference existed in
begging frequency or feedings between large and small
nestlings, regardless of hatching pattern. Larger nestlings
were closer to the adult prior to 42% of all feedings and were
fed first 92% of the time. Small nestlings were rarely close
to the adult prior to feedings and were fed first only 8 % of the
time. When food was not limited, nestling position or feeding
sequence did not differ. These data suggest that adult White-
crowned Pigeons in the Florida Keys have little potential to
counteract the competitive asymmetries between different-
sized young and, ultimately, the starvation of smaller nestlings
as a result of this competition.


MOVEMENTS AND MORTALITY OF WHITE
IBISES (EUDOCIMUS ALBUS) AS DERIVED FROM
RECOVERIES OF BIRDS BANDED IN THE
SOUTHEASTERN UNITED STATES
PETER C. FREDERICK
University of Florida, Gainesville, Florida 32611, USA

From 1957 to 1987, 18,713 White Ibises have been banded
with USFWS leg bands and/or color marks at colonies in the
southeastern United States. These bandings have resulted in
163 recoveries (0.8% recovery rate), 150 of which have
usable information. These returns indicate that ibises, in
general, migrate to the south during the winter months,
apparently often crossing the straits of Florida to Cuba (16%
of recoveries). Few returns were from further south, and it is
likely that there is little interchange with Scarlet (Eudocimus
ruber) and White Ibis populations in the southern Caribbean
rim. Juvenile ibises tend to undergo rapid postbreeding
dispersal, often towards the north. Although there are several
problems with the banding data (too few adults banded,
visibility bias for juveniles, inconsistent hunting pressure),
the band recoveries suggest that the North American White
Ibis population experiences 62% mortality in the first year of
life, 33% in the second year, and 26% mortality for adults.
With these rates, it is estimated that 2.07 young must be
produced on average per breeding pair to maintain a stable
population. These figures may, however, be obsolete, since
over 50% of the returns were from hunting, a condition which
may have been greatly reduced in the past two decades.

EFFECTS OF COLONIZATION PATTERNS,
DISPERSAL BARRIERS, AND ISLAND SIZE ON
GENETIC VARIATION PATTERNS IN CARIB-
BEAN YELLOW WARBLERS
NEDRA K. KLEIN
Museum of Zoology, University of Michigan,
Ann Arbor, Michigan 48109, USA

I used a restriction endonuclease analysis of mitochondrial
DNA (mtDNA) to estimate genetic variation within and
among Caribbean populations of the Yellow Warbler
(Dendroica petechia) sampled from 11 islands and 4 coastal
Venezuelan localities. There was no clear-cut pattern of
greater among-population genetic variation in the West Indies
relative to Venezuela. However, there was a significant
effect of island size on within-population variation (lower
levels of variation within populations on smaller islands).
There was also a phylogeneticc effect" on variation: multiple
colonizations of individual islands and of the West Indies as
a whole (inferred from a phylogenetic analysis of mtDNA)
was correlated with increased genetic variation within
populations and among islands.

THE GREATER ANTILLEAN NIGHTJAR:
IS IT ONE SPECIES?
ORLANDO GARRIDO1 AND GEORGE B. REYNARD2
1Museo Nacional de Historia Natural, La Habana, Cuba;
2105 Midway St., Riverton, NJ 08077, USA

The Greater Antillean Nightjar is found in Cuba, Cayo Coco,
Isle of Youth, and Hispaniola. It was described in Cuba as
Antrostomus cubanensis by Lawrence (1862), in Hispaniola
(Haiti) as A. eckmani by Lonneberg (1929), and currently is
lumped as Caprimulgus cubanensis (AOU 6th Check-list
1983). A note there suggests that two species may be present,
based on vocalization differences. The song in the Dominican
Republic is a 'click,' plus a 2-syllable phrase, fitting the
rhythm of the common name there, "Pitangua." In Cuba, the
song is a 4-syllable phrase, not 3 syllables, as indicated in the
common name "guabairo." It could be paraphrased as "gua
bai ah ro". In Hispaniola, the song is higher pitched by 250
Hz, longer in duration (1.2 vs. 0.6s), and slower in delivery (at
2 vs. 1.5s intervals). Among plumage differences are (1) the
size of the beige underside distal area of the rectrices-length
70mm in Hispaniolan vs. 25mm in Cuban birds, (2) blackish
crown and hind neck streaks wider than in Cuba, and (3)
coverts in the vent area are not streaked in Hispaniolan
specimens as they are in Cuba. Our information supports
returning to two species: Caprimulgus eckmani, the
Hispaniolan Nightjar; and C. cubanensis, the Cuban Night-
jar. Tape recordings and sonograms will be presented.

PRELIMINARY STATUS OF THE WEST INDIES'
ONLY NUTHATCH
P. WILLIAM SMITH AND SUSAN A. SMITH
South Florida Research Center, Everglades National Park
P. 0. Box 279, Homestead, Florida 33090, USA

We studied Sitta pusilla insularis, the endemic race of the
Brown-headed Nuthatch confined to Grand Bahama Island,
in both the museum and field, and compared it to south
Florida populations of the same species. The insularis race
was diagnosed largely based on a longer, straighter bill, but
we learned that the type's bill had been mismeasured and that
specimens from Grand Bahama differed only slightly from
those taken in nearby Florida. In life, the Grand Bahama
nuthatch is different visually, vocally, and behaviorally
compared to south Florida populations. We encountered it
with less than 5% the frequency that might be expected from
densities and detection coefficients determined by John Emlen
on Grand Bahama about 25 years ago. We believe that the
West Indies' only nuthatch has recently declined precipitously
and may be heading for extinction. We speculate that this
may be a consequence of its isolation and ecological re-
quirements compared to the nature of pine forest regenera-
tion following rapid massive clearcutting of its single-island
range.

CONSERVATION OF BIOLOGICAL DIVERSITY
IN THE NATURAL PINE FORESTS OF THE
BAHAMA ISLANDS
CHRISTOPHER C. RUSSELL
Forestry Section, Department of Lands and Surveys
P. 0. Box N-592, Nassau, Bahamas

The scientific management of the pine forests of the Bahama
Islands significantly contributes to the conservation of bio-
logical diversity of flora and fuana. Some notable plant
species adapted to varied site conditions include thatch palms
(Sabal palmettos) and poison wood (Metopium toxiferum),
among others. Enthusiastic bird watchers have a diversity of
bird life to view that rivals the finest elsewhere, and includes
Turkey Vulture (Cathartes aura), Red-tailed Hawk (Buteo
jamaicensis), and Bahama Parrot (Amazona leucocephala
bahamensis). All wild birds are protected by Bahamian law
and numerous national parks and bird reserves have been
dedicated to protect and conserve biological diversity.
Nevertheless, law enforcement is difficult. The concept of
multiple-use forestry, as practiced by the Forestry Section,
can be used to achieve a balance for the co-existence of all
facets of forest management and the environment. Further,
great care and control can be exercised in forest practices, and
adjustment made to conserve the genetic resources of both
flora and fauna of the pine forests.

HABITAT CONSTRAINTS ON THE DISTRIBU-
TION OF PASSERINE RESIDENTS AND
NEOTROPICAL MIGRANTS IN LATIN AMERICA
CHANDLER S. ROBBINS, BARBARA A. DOWELL, AND
DEANNA K. DAWSON
U.S. Fish & Wildlife Service, Patuxent Wildlife Research Center,
Laurel, MD 20708, USA

With continuing tropical deforestation, there is increased
concern for birds that depend on forest habitats in Latin
America. During the past 10 northern winters, we have
conducted quantitative studies of habitat use by wintering
migrant songbirds and by residents in the Greater Antilles,
Mexico, Central America, and northern South America.
Many migrants, but few residents, winter in forest fragments
and in certain arboreal agricultural habitats (citrus, cacao,
shade coffee). Many other agricultural habitats (sun coffee,
mango, commercial banana plantations, and heavily grazed
pasture) are avoided by most birds. Some species, such as
thrushes and ground-feeding warblers, depend on closed-
canopy forest. Some, such as Northern Waterthrush (Seiurus
noveboracensis) and Prothonotary Warbler (Protonotaria
citrea), winter primarily in mangroves or other swamp for-
ests. The majority of neotropical migrant passerines winter
in forest fragments and certain agricultural habitats, as well
as mature forest; but many resident species, especially
suboscines (Furnariidae, Dendrocolaptidae, Formicariidae,
Papridae), are heavily impacted by loss and fragmentation of
the forest.

and Horned Owl Bubo virginianus nests at the biosphere re-
serve of Sian Ka'an in 1992 and 1993. We recorded 25
Osprey nests, 11 of which were active and 5 were successful
with 8 fledglings. On the other hand, we recorded four
Homed Owl nests, three of which were active and one of them
was successful with two fledglings. Ospreys built their own
nests on isolated sites and they were exposed to the wind,
whereas Homed Owls used nests built by other bird species,
including Osprey, and may use active nests. We suggests that
the wind played a major role in the breeding success of
Ospreys and Horned Owls in Sian Ka'an.

ASSESSING THE EFFECT OF HABITAT
CHANGES ON THE WATERBIRD POPULATIONS
OF HELLSHIRE, ST. CATHERINE, JAMAICA

Waterbirds are valuable as indicators of habitat change. This
has been well documented in temperate wetlands, but no
studies have been conducted in such habitats in the Caribbean.
Studies were conducted in St. Catherine, Jamaica, on a
natural and a man-made wetland; the latter was a recently-
constructed natural sewage treatment plant. These studies
were made to determine the effect of the second habitat on the
waterbirds of Hellshire, St. Catherine. Numbers of adults and
juveniles were counted in populations in the natural wetland
during an 18-month period, and in the man-made wetland
during a 12-month period. The results were compared to
assess the effects of the man-made system. These results
showed that changes in extent and quality of the available
wetland habitat influenced the composition of the waterbird
population.

RAPTOR MIGRATION IN THE CARIBBEAN:
THE JAMAICAN PERSPECTIVE
MARCIA MUNDLEI AND CATHERINE LEVY2
1Department. of Zoology, University of the West Indies, Mona,
Kingston 7 Jamaica; 22 Starlight Avenue, Kingston 6, Jamaica

There is a general consensus among the birding community
in Jamaica that the migrant birds of prey observed on the
island are largely vagrants. To test this hypothesis, a 13-year
(1980-1993) record of data available from the Gosse Bird
Club (Jamaica) was analysed. A total of 8 species of raptors
were recorded during this period. Of these, the American
Kestrel (Falco sparverius) and the Red-tailed Hawk (Buteo
jamaicensis) are resident. The data support the hypothesis,
although there may be some degree of under-reporting due to
the inexperience of bird watchers with some species, and the
generally low numbers of migrating individuals. An assess-
ment is made of the suitability of Jamaica as a habitat for birds
of prey in terms of vegetation type and food availability,
taking into account the status of the species in their breeding
range.

A Biodiversity Monitoring Project was recently initiated in
Antigua under the auspecies of the Environmental Awareness
Group. One of the most important components of the project
is the assessment and cataloguing of native species of plants
and animals, targeting the remnant moist forest environments
and wetlands on Antigua. We hope this will lead to a better
system of classification and management for parks and
protected areas in Antigua and Barbuda.

Captive efforts for the Puerto Rican Parrot (Amazona vittata)
have been ongoing since 1972. Progress in this part of the
parrot project has been particularly slow and expensive. At
present, 57 Puerto Rican Parrots and 34 Hispaniolan Parrots
(Amazona ventralis) are housed in the Luquillo aviary. In
February 1992, a series of modifications on the physical plant
of the Luquillo Aviary, as well as on the management and
health care of the captive parrots, was initiated. All captive
breeding pairs have been supplied with a PVC nest prototype


with a palm tree entrance to mimic natural cavities. These
nests are reusable, and are proving to keep nesting females in
a drier, more sterile environment. All captive breeding units
(cage with breeding pair and nest structure) are being re-
motely monitored by a closed-circuit TV camera system. At
present, we have successfully pair-bonded 11 genetically
compatible pairs and placed these birds in breeding units.
Microbiology studies were conducted.

This presentation examines all available literature on this
Red Data Book endemic owl, and discusses the various
conflicting accounts of habitat use by this species and alarming
lack of behavioral and ecological data available for conser-
vation of this owl. The attendant habitat and species man-
agement concerns which arise because of this lack of data are
also addressed. I discuss present habitat availability on the
island of Tobago and possible threats posed to the species
there. I close with the outline of the Trinidad Wildlife
Section's proposal to study this species and the response of

SOME IMPLICATIONS OF SMALL POPULATION
SIZE FOR MANAGEMENT OF
WATERBIRDS IN JAMAICA
PETER R. BACON AND ANNE C. E. MORGAN
Zoology Department, University of the West Indies,
Mona, Kingston, Jamaica

Relatively little scientific work has been done on waterbird
populations and habitats in Jamaica. Consequently, the data
base for rational management is poor. Records from wetland
and coastal sites over the past 15 years contain little more than
a list of species present during a single observation period and
little consecutive monthly or seasonal data are available.
These and recent studies at north and south coast wetlands
show a high species diversity at some sites, but low numbers
at all sites. No site had more than 1000 birds of all species
recorded at any one time and passage migrants increased in
numbers only slightly; so small populations of waterbirds
appear to be characteristic of Jamaica. Research is needed to
determine whether habitat quality is restricting resident spe-
cies and the extent to which Jamaica is used as a shorebird
flyway; but small size has implications for waterbird man-
agement. Few sites in Jamaica meet international criteria of
importance for waterfowl conservation, can support sport
hunting, or have potential for birdwatching or ecotourism.
Consequently, funding for ecological research, waterbird
protection, or possible population enhancement activity may
not be readily available. These and other management
problems are discussed.

THE IMPACT OF THE LANDSCAPE ON AVIAN
COLONIZATION OF
ISOLATED PATCHES OF HABITAT

Laboratory, Drawer E. Aiken, South Carolina 29802, USA

The placement of a habitat patch within its local landscape
can strongly affect the ability of organisms to find and
colonize that patch. A habitat patch that is relatively isolated
from potential sources of dispersers may be less likely to
support a population than is a similar patch that is close to
such sources. We demonstrate that this landscape effect can
be seen even with relatively vagile organisms such as birds,
which are not generally considered dispersal-limited. We
have studied the distribution of Bachman's Sparrow
(Aimophila aestivalis) in the managed pine woodlands of the
Savannah River Ecology Laboratory in the coastal plain of
South Carolina. In 1991 and 1992, we followed the sparrow's
ability to colonize two "linear landscapes," which were sets


of clearcuts that began near a source of dispersing birds, and
extended in one direction through a landscape matrix of
unsuitable habitat. Thus, the clearcuts differed from one
another primarily in their isolation from potential sources.
Surveys of singing male sparrows during the breeding season
showed that densities of the sparrow decreased with increasing
distance from potential sources. The effect of patch isolation
within the landscape could provide an explanation for this
species' population decline during the last 50 years, and may
suggest management strategies for halting the sparrow's
decline.

COLLECTING INFORMATION FOR AN ISLAND
DATABASE OF BIRD RECORDS
or
WHO IS THE FINAL AUTHORITY?
CATHERINE LEVY
2 Starlight Avenue, Kingston 6, Jamaica

Using illustrations from recent unusual observations in Ja-
maica, this paper sets out what type of information can be
collected from regularly kept records of bird species. Ideas
are presented on the application and importance of this
information to programs for conservation of avifauna or of
natural areas. The compilation of records can be useful in
providing a basis for further study and research of a species
and its habitat, for producing an atlas and checklists, and for
involving groups and individual volunteers in bird observa-
tion and nature conservation. Finally, suggestions on types
of databases and headings will be presented. Examples of
acceptable records and standards will be discussed.

A system of monitoring of birds has been established in Lago
Enriquillo. During the first year, the main interest has been
the determination of species richness and the identification of
critical habitats, as well as the census of the populations of the
Greater Flamingo (Phoenicopterus ruber ruber), herons
(Egretta sp.), and migratory species. In a fringe of 325.4 km2
around the lake, 9 critical habitats used by birds for foraging
and breeding activities were determined; these are: the shore
and swampy areas (17%), mangroves (15%), mixed crops
(e.g., rice) (14%), temporarily inundated pastures (14%), and
dry forests around the lake and on the islets of Cabritos, La
Islita, and Barbarita (38%); others (2%). The water surface
of the lake is 238.0 km2. Three critical habitats are used by
the flamingo for foraging: Boca de Cach6n, with a monthly
average of 466 individuals during the period from March to
May 1993, and Villa Jaragua and Bahfa de Los Rios with
averages of 216 and 115 individuals, respectively.

VOCAL BEHAVIOR OF THE ST. ANDREW VIREO
(VIREO CARIBAEUS)
JON C. BARLOW AND MARK K. PECK
Department of Ornithology, Royal Ontario Museum,
Toronto, Ontario, M5S 2C6, Canada

Vireo caribaeus, of the southeastern Caribbean Isla San
Andr6s, is vocally unique among species of the subgenus
Vireo because it: (a) utters monosyllabic "chatter" song,
bisyllabic songs, and general polysyllabic song of three or
more kinds of syllables; (b) has incorporated repetitive
congested song into its song types repertoire; and (c) does all
of the above with only six different syllables and their
variants. Some of the six syllables are shared with other
western Caribbean insular and continental species of the V.
griseus superspecies complex. Isolation of a small founder
population on tiny San Andr6s (34 km2), which experienced
cultural drift or evolution, may explain in V. caribaeus the
origin of such complex song from such a simple syllable
repertoire.

THE RELEASE PROGRAM FOR THE PUERTO
RICAN PLAIN PIGEON
CARLOS R. Ruiz, JUAN J. MORALES, AND ANASTACIO ORTIZ
Department of Natural Resources, San Juan, Puerto Rico, 00906

Eight Puerto Rican Plain Pigeons (Columba inornata
wetmorei) were released to the wild in April 1993. All
pigeons were raised by their own parents representing six
different families. Birds were moved from the Humacao
Aviary to a releasing cage (3 x 3 x 10mn) at Cidra. We
provided daily pellets, natural food, and water. A total of 22
plant species were provided and most of them tried and
accepted. Preferred fruits were Roystonea borinquena,
Scheflera morototoni, Lantana camera, Psychotriaberteriana,
and Nectandra membranacea. The birds were acclimatized
for five weeks in the releasing cage. During the last two
weeks a radio transmitter was installed to each pigeon to
study their behavior with this device. All pigeons were
released and monitored with the radiotelemetry equipment.
Three pigeons were lost, one illegally shot and two killed by
Red-tailed Hawks (Buteo jamaicensis). Most of the birds
integrated into the wild population of plain pigeons and at the
end of the study two released pigeons started to breed in two
different areas. Dispersion of pigeons varied from 0.2 km to
over 7.0 km (maximum range of the receiver). All pigeons
were monitored for three months, the life of the transmitters'
batteries.

ORLANDO H. GARRIDO RECEIVES SCO AWARD AS OUTSTANDING ORNITHOLOGIST
ARTURO KIRKCONNELL


During the 1993 annual meeting of the SCO, Orlando Garrido
was presented with the Society's Outstanding Ornithologist
Award in recognition for his valuable contributions to the
fields of systematics, ecology, and conservation of Cuban
birds. Below is the text of the presentation made at the
banquet.

Members of the Society of Caribbean Ornithology
Guests: Ladies and Gentlemen,
Today I have the pleasure and great satisfaction to render
honor to the person Iconsider the most outstanding systematist
of Cuban vertebrates: Orlando H. Garrido.
His serious study of biology began when he was just 15
years old, when he dedicated most of his time to collecting
insects, mainly butterflies and beetles. His interest in orni-
thology was stimulated in 1952 when he met his professor,
Oscar Owre, at the University of Miami. Orlando stayed at
the University for 4 years, taking courses in biology and
business administration, but did not finish his studies there
because the funds from his tennis scholarship ran out. Rather,
he completed his education through self-teaching .
For 7 years he traveled the world with a tennis racket,
playing the European, African, Asian, and American circuits,
for a total of 54 countries visited. In 1961 he returned to Cuba
and began to study the country's birds in close collaboration
with James Bond.
As relevant as is his work in ornithology, so is his work with
other groups of Cuban vertebrates. His broad knowledge,
experience, and field skill made him the prominent authority,
not only of birds, but also of reptiles and coral reef fishes.
Orlando's knowledge of mammals and invertebrates, in
particular the systematics of the tenebrionid beetles, is also
remarkable.
Everyone who knows him has a favorite anecdote about
Orlando. Each is unique; for example when he discovered a
new species of hutia in a cay after he found only a fecal pellet,
or when he captured with his bare hands a Black-and-white
Warbler (Mniotilta varia) a few seconds after telling his field
assistant he was going to do it. On one occasion when I
wanted to test his field skills, I asked Orlando to guess a new
bird I had seen in my last field trip. He only asked about the
exact date of my observation. When I replied, Orlando told
me not only the correct species, but also the sex.


Orlando Garrido is an untiring investigator of our
biodiversity, as demonstrated by his many discoveries: of 9
species of Cuban hutia known to science, 5 were discovered
by Orlando; 91 taxa of reptiles, 13 taxa of birds, 30 new
records of fishes, and 3 new to science are attributed to
Orlando Garrido. He has found more than 50 new species of
invertebrates, 15 of which have been dedicated to him.
His publication record is also prolific, containing 181
titles, including several books, such as "The Catalogue of
Cuban Birds" and "Ecological Segregation in Cuban Avi-
fauna."
Recently I asked him what was his greatest satisfaction in
his long career. I was not surprised to hear that everything has
been a great satisfaction to him: every discovery, each de-
scription, the rediscovery of the many Anolis species, of the
Snowy Plover in Cuba, and on and on.
His greatest wish is to see the Zapata Rail (Cyanolimnas
cerverai), the only bird in Cuba that he has not observed. He
has never lost the hope to find it someday, but I feel sorry for
the rail that has the misfortune or disgrace of this long-wished
meeting.
Among the many international honors or charges bestowed
on him are an American Ornithologists' Union Fellowship,
membership on the International Council for Bird Protection,
Honorary Membership in the Polish Journal, The Ring, and
Scientific Advisor for the RARE Center.
For the human point of view, there are three adjectives that
can not be missed when we talk about Orlando. They are
giving, modest and last, but not least, that which forms much
of his personality his sense of humor.
"The Field Marshall," he is called by all of us who love,
praise, and respect his work. I feel lucky to be working with
him in this period of his life. I want to thank the Organizers
of this meeting for conferring to me the great honor of
contributing this short, but honest, homage to Orlando.
On behalf of all the persons present here, our most sincere
respect and admiration. We thank you, Orlando, for your
enduring contributions to Cuban natural history.
We wish you good health to continue your prolific work
which you have so freely shared with all of us.

Congratulations, Orlando!

ASSOCIATION FOR PARROT CONSERVATION


We wish to announce the formation of a conservation group,
the Association for Parrot Conservation (APC). Concerned
scientists met in Washington, D.C., in October 1993 to
discuss the present status, threats, and conservation of the
world's parrot populations. As a result, it was decided that
there was an urgent need to form an organization that provides
a forum for parrot specialists to address critical research,
management, and conservation needs.
The mission of the organization is to promote the con-
servation of wild parrot populations and their habitat through
scientific research, policy recommendations, and education.
Initial emphasis will be placed on New World parrots. APC
was founded to (1) scientifically evaluate conservation al-
ternatives for maintaining wild populations and their habitats
(e.g., field research and recovery, habitat preservation, eco-


El Pitirre 7(1)


system management, conservation education, ecotourism,
captive breeding, reintroduction, sustainable use, and trade
recommendations) as well as their application on a case-by-
case basis to parrots, (2) educate scientists, decision-makers,
and the public about the potentials and limitations of con-
servation alternatives, (3) create a communications network
for those concerned with the conservation of wild parrot
populations, and (4) facilitate local and regional conservation
projects. The guiding principle of the association is to promote
techniques and strategies that maximize the conservation of
biological diversity.
An Executive Council of 17 members was elected. The
President will be Dr. Enrique Bucher from Argentina, who is
well-known for his studies of New World parrots and the
sustainable use of biological resources. Dr. Bucher hopes that

"by initiating and facilitating effective parrot conservation
actions, the association will make a substantial contribution
to conserve the parrots of the New World, of which 30% of
the species are at present threatened."

REQUESTS FOR INFORMATION


BAHAMA WHrrE-CHEEKED PINTAIL INFORMATION NEEDED.-We
are compiling information on the distribution, status, and
conservation needs of the Bahama race of the White-cheeked
Pintail (Anas b. bahamensis) throughout the West Indies. We
especially need information from Hispaniola (Haiti and the
Dominican Republic), the U. S. Virgin Islands, Netherlands
Antilles (especially St. Martin), St. Barthelemy, St. Kitts,
Nevis, Montserrat, and Guadeloupe, but would also welcome
contributions from other islands. Please contact Dr. Frank
McKinney and Bethany L. Woodworth, James Ford Bell
Museum of Natural History, University of Minnesota, 100
Ecology Building, 1987 Upper Buford Circle, St. Paul,
Minnesota 55455, U.S.A. We request that contributors fill
out a simple two-page questionnaire, but unpublished data
would also be appreciated. All contributors will be ac-
knowledged and properly cited, and contributors will be
provided with a copy of the report.

INFORMATION REQUESTED ON GRASSHOPPER SPARROWS.-I hope
that some members of the Society of Caribbean Ornithology
might be able to provide information regarding the biology of
Grasshopper Sparrows (Ammodramus savannarum) from the
Caribbean region. I am responsible for the American Orni-
thologists' Union Grasshopper Sparrow account for the Birds
of North America series. Other than field guides and older
references, such as Wetmore and Swales' The birds of Haiti
and the Dominican Republic, I am not aware of any published
data or information for Grasshopper Sparrow from the Car-
ibbean. Inclusion of such information, if it exists, would be a
meaningful addition to this account. If members are aware of
any references (Spanish is fine), data, or colleagues working
in grassland habitats, I would be most appreciative if you
would let me know. I am especially interested in breeding
seasonality and behavior, population status, and taxonomy.
Any help will be greatly appreciated and full acknowledged.
