Hay pocos estudios sobre la dieta en aves neotropicales, incluidos lo psitácidos. La lapa verde (Ara ambiguus) se alimenta de las semillas del almendro de montaña (Dipteryx panamensis), titor (Sacoglottis trichogyna) y otras especies. Sin embargo no hay repor- tes de esta especie alimentándose de almendro de playa (Terminalia catappa). Aquí informamos que lo hace y que usa hojas como herra- mienta. Su consumo podría deberse a la falta de frutos de D. pana- mensis y S. trichogyna, y al alto valor nutricional de la semilla. Usar las hojas para desprender el pericarpo puede ser una estrategia para evitar su sabor amargo.
We present new distribution information for 19 species of Costa Rican birds. Thirteen species show changes in altitudinal distribution, 9 are recorded at higher elevations such as Egretta rufescens (Gmelin, 1789), Heliomaster constantii (Delattre, 1843), Myiozetetes cayanensis (Linnaeus, 1766), and Lonchura malacca (Linnaeus, 1766), and 4 are recorded at lower elevations,
Gray-bellied Hawk (Accipiter poliogaster) is a diurnal raptor with a distribution range and movements poorly known. A juvenile was recorded in Costa Rica in 2008 and 2009 for in the Caribbean lowlands. In this note we reported the first adult observation for Costa Rica and a new locality. Even though is uncertain how this species of bird was able to arrive to Costa Rica, we discuss possible explanations for that.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
