Birds of prey of a semi-arid ecosystem in Falcón State, Venezuela: Diversity and ecological patterns

Notes are presented on the species richness, diet, and reproduction of birds of prey in a semi-arid ecosystem of north­western Venezuela, based on nine months of daytime observations. A total of sixteen resident and two migratory species, belonging to four orders and five families, were recorded. Nests of eight species were observed and described. The diets of five species were determined through analyses of pellets and other prey remains collected around nests. The Easten Cotton­tail Rabbit, Sylvilagus floridanus (J. A. Allen, 1890), was the most frequent prey item. Additionally, negative interactions between rural communities and raptors are reported, including the use of pesticides by local residents to control species perceived as threats to domestic animals.
