The Lesser Antilles Incuding Trinidad
The brilliant Lesser Antillean Barn Owl again showed superbly. One of several potential splits not yet recognized by the IOC (Pete Morris) THE LESSER ANTILLES INCUDING TRINIDAD 5 – 20/25 JUNE 2015 LEADERS: PETE MORRIS After our successful tour around the Caribbean in 2013, it was great to get back again this year. It all seemed pretty straightforward this time around, and once again we cleaned up on all of the available endemics, po- 1 BirdQuest Tour Report:The Lesser Antilles www.birdquest-tours.com The fabulous White-breasted Thrasher from Martinique (Pete Morris) tential splits and other goodies. For sure, this was no ordinary Caribbean holiday! During the first couple of weeks we visited no fewer than ten islands (Antigua, Barbuda, Montserrat, Dominica, Guadeloupe, Martinique, St Lucia, St Vincent, Barbados and Grenada), a logistical feat of some magnitude. With plenty of LIAT flights (the islanders refer to LIAT as ‘Leave Island any Time’ and ‘Luggage in Another Terminal’ to name but two of the many funny phrases coined from LIAT) and unreliable AVIS car hire reservations, we had our work cut out, but in the end, all worked out! It’s always strange birding on islands with so few targets, but with so many islands to pack-in, we were never really short of things to do. All of the endemics showed well and there were some cracking highlights, including the four smart endemic amazons, the rare Grenada Dove, the superb Lesser Antillean Barn Owl, the unique tremblers and White-breasted Thrashers, and a series of colourful endemic orioles to name just a few! At the end of the Lesser Antilles adventure we enjoyed a few days on Trinidad. -

E-mail: [email protected] Abstract We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item. -

Robert Ridgway 1850-1929
NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS VOLUME XV SECOND MEMOIR BIOGRAPHICAL MEMOIR OF ROBERT RIDGWAY 1850-1929 BY ALEXANDER WETMORE PRESENTED TO THE ACADEMY AT THE ANNUAL MEETING, 1931 ROBERT RIDGWAY 1850-1929 BY ALEXANDER WETMORE Robert Ridgway, member of the National Academy of Science, for many years Curator of Birds in the United States National Museum, was born at Mount Carmel, Illinois, on July 2, 1850. His death came on March 25, 1929, at his home in Olney, Illinois.1 The ancestry of Robert Ridgway traces back to Richard Ridg- way of Wallingford, Berkshire, England, who with his family came to America in January, 1679, as a member of William Penn's Colony, to locate at Burlington, New Jersey. In a short time he removed to Crewcorne, Falls Township, Bucks County, Pennsylvania, where he engaged in farming and cattle raising. David Ridgway, father of Robert, was born March 11, 1819, in Harrisburg, Pennsylvania. During his infancy his family re- moved for a time to Mansfield, Ohio, later, about 1840, settling near Mount Carmel, Illinois, then considered the rising city of the west through its prominence as a shipping center on the Wabash River. Little is known of the maternal ancestry of Robert Ridgway except that his mother's family emigrated from New Jersey to Mansfield, Ohio, where Robert's mother, Henrietta James Reed, was born in 1833, and then removed in 1838 to Calhoun Praifle, Wabash County, Illinois. Here David Ridgway was married on August 30, 1849. Robert Ridgway was the eldest of ten children. -

The Feeding Ecology of Tanagers and Honeycreepers in Trinidad

Growth Rate Variation Among Passerine Species in Tropical and Temperate Sites: an Antagonistic Interaction Between Parental Food Provisioning and Nest Predation Risk

Passerine birds represent an intriguing case because differing theories yield the possibility of an antagonistic interaction between nest predation risk and food delivery rates on evolution of growth rates. We test this possibility among 64 Passerine species studied on three continents, including tropical and north and south temperate latitudes. Growth rates increased strongly with nestling predation rates within, but not between, sites. The importance of nest predation was further emphasized by revealing hidden allometric scaling effects. Nestling predation risk also was associated with reduced total feeding rates and per-nestling feeding rates within each site. -

An “HO” placed after a species name means the bird was heard only and not sighted, while “LO” designates those few species only spotted by the trip leader or a lodge guide. The ordering of families and species follows the Asa Wright Nature Center booklet we used on the trip, with a few exceptions, i.e., where family affiliation or species-level taxonomy have been changed to reflect the most recent updates appearing in the Clements Checklist of Birds of the World (Cornell Lab of Ornithology; http://www.birds.cornell.edu/clementschecklist/).

Avian Distribution Along a Gradient of Urbanization in Northeastern Puerto Rico
Ecological Bulletins 54: 141–156, 2013 Avian distribution along a gradient of urbanization in northeastern Puerto Rico Edgar O. Vázquez Plass and Joseph M. Wunderle Jr We studied avian distribution along an urban to forest gradient in northeastern Puerto Rico to document how dif- ferent species, species groups, and diet guilds respond to urbanization. Mean avian abundance and species richness sampled at 181 point count sites increased with urbanization and was associated with measures of developed habitat, pasture and elevation. Endemic species were sensitive to urbanization as evidenced by their negative association with an urbanization index, positive association with forest cover, and their rarity in urban habitat in contrast to their abundance and species richness in forest. Exotic species showed the opposite pattern by a positive association with an urbanization index and highest abundance and species-richness in suburban/urban habitats and absence from forest. Resident (non-endemic) species were found throughout the gradient, although species differed in the locations of peak abundance along the gradient. Resident species also displayed a positive association with the urbanization index and their abundance and species richness increased with urbanization. The increased avian abundance and species richness with urbanization was attributed to exotic granivores and omnivores and resident insectivores, granivores and omnivores. We hypothesize that availability of nearby undeveloped habitats may be critical for maintaining avian abundance and species richness in Puerto Rico’s urban areas, but emphasize that research is needed to test this hypothesis.
