Avian distribution in Dominican shade coffee plantations : area and habitat relationships
(1999)
Residents and wintering Nearctic migrants were sampled by point counts in 40 small to medium-sized (0 .07-8.65 ha) shade coffee plantations with an overstory of Inga vera in the Cordillera Central, Dominican Republic. The ...
Avian resource use in Dominican shade coffee plantations
(1998)
We quantified foraging behavior of 19 bird species in shade coffee plantations in the Dominican Republic to document and evaluate their use of food resources in the shade overstory relative to the coffee understory.
Breeding-season food habits of burrowing owls (Athene cunicularia) in southwestern Dominican Republic
(1998)
Diet data from 20 Burrowing Owl (Athene cunicularia) nests were collected in southwestern Dominican Republic in 1976, 1982, and 1996. Invertebrates (53.3%) comprised the most numerous prey items (N = 396) delivered to nests ...
Ecological relationships of two todies in Hispaniola : effects of habitat and flocking
(1996)
We studied microhabitat use, foraging and social behavior of Broad-billed (Todus subulatus) and Narrow-billed (T. angustirostris) Todies in two areas o f sympatry in the Cordillera Central of the Dominican Republic. Solitary ...
The composition and foraging ecology of mixed-species flocks in pine forests of Hispaniola
(1996)
[English] We determined the flocking propensity of 48 species of birds occurring in native pine forest in the Cordillera Central of the Dominican Republic, and the species composition of 180 mixed-species flocks.
Observations on the abundance, site persistence, home range, foraging, and nesting of the Pine Warbler on Hispaniola, and first record of ground nesting for this species
(1999)
[English] We studied the permanent resident Pine Warbler (Dendroica pinus) from October-April 1996–1997 and 1997–1998 in high-elevation Hispaniolan pine (Pinus occidentalis) forests of the Sierra de Bahoruco in the Dominican ...

Speciation, heterochrony, and genetic variation in Hispaniolan Palm-Tanagers
(1990)
We documented levels of genetic variability for two species of Hispaniolan palm-tanagers. Significant differences between age classes in levels of genetic heterozygosity were concordant with an age dimorphism in foraging ...
Behavioral and morphological correlates of heterochrony in Hispaniolan Palm-Tanagers
(1994)
We documented the occurrence of heterochrony for morphological and behavioral characters in two species of Hispaniolan Palm-Tanager.
