Discovery of a giant chameleon-like lizard (Anolis) on Hispaniola and its significance to understanding replicated adaptive radiations
(2016)
We report a new chameleon-like Anolis species from Hispaniola that is ecomorphologically similar to congeners found only on Cuba. Lizards from both clades possess short limbs and a short tail and utilize relatively narrow ...
Retrofitting power poles to prevent electrocution of translocated Ridgway’s Hawks (Buteo ridgwayi)
(2019)
Abstract: A translocation program for Critically Endangered Ridgway’s Hawks (Buteo ridgwayi) in the Dominican Republic initially met with limited success because hawks were being electrocuted on power poles around the ...
Surveys and breeding biology of Buteo ridgwayi (Ridgway's Hawk) in Los Haitises, Dominican Republic
(2005)
We conducted surveys for the endangered Ridgway's Hawk, Buteo ridgwayi, in Los Haitises National Park, Dominican Republic, and in areas outside the park during the breeding seasons 2002 and 2003. In 2002, we recorded 47 ...
Breeding season ecology and behavior of Ridgway's Hawk (Buteo ridgwayi)
(1981)
Ridgway's Hawk (Buteo ridgwayi) is endemic to Hispaniola and its satellites, where it occurs in a wide variety of habitats. We studied this hawk in the wet limestone karst forest of the Dominican Republic between January ...
Population genetics and relatedness in a critically endangered island raptor, Ridgway's Hawk Buteo ridgwayi
(2013)
Many island avian populations are of conservation interest because they have a higher risk of extinction than mainland populations. Susceptibility of island birds to extinction is primarily related to human induced change ...
Breeding ecology and predictors of nest success in the Critically Endangered Ridgway’s Hawk Buteo ridgwayi
(2015)
Ridgway’s Hawk Buteo ridgwayi is a Critically Endangered forest raptor endemic to the island of Hispaniola in the Caribbean. The species is currently limited to a small area on the north-east coast of the island, with fewer ...
Nestling sex ratio in a critically endangered dimorphic raptor, Ridgway's Hawk (Buteo ridgwayi)
(2013)
[English] Variation in nestling sex ratio is an important concept in population ecology, and has particular implications for the conservation status of small populations. Research on species exhibiting Reversed Sexual Size ...
Social and genetic mating system of Ridgway's hawk (Buteo ridgwayi), an endemic raptor on Hispaniola
(2013)
Patterns of social organization and mating systems have been shown to be functions of ecological factors such as resource allocation and breeding density. In some species, particularly birds, social organization and genetic ...
Observation of geophagy by Hispaniolan Crossbill (Loxia megaplaga) at an abandoned bauxite mine
(2012)
Abstract: I report an observation of endangered Hispaniolan Crossbill (Loxia megaplaga) feeding on soils near abandoned bauxite mines in the Sierra de Bahoruco, Dominican Republic. Although geophagy has been widely reported ...
Comments on the ecology and status of the Hispaniolan Crossbill (Loxia leucoptera megaplaga), with recommendations for its conservation
(1994)
The rare and unique Hispaniolan White-winged Crossbill (Loxia Ieucoptera megaplaga) is endemic to the mountains of Hispaniola. It is specialized for harvesting seeds from the cones of Pinus occidentals, and is dependent ...
