Anidamientoydieta de Harpia harpyja Linnaeus en la Comunidad Nativa de Infierno, Madre de Dios, Perú

Abstract

El Águila Arpía (Harpia harpyja Linnaeus) es la rapaz de mayor tamaño que habita los bosques amazónicos, sin embargo en el Perú, es muy poco lo que se sabe de esta especie. Desde 1996 a 2001, realizó una investigación en la Comunidad Nativa de Infi erno para obtener información sobre la biología de la especie mediante la localización y observación de nidos activos y abandonados. La investigación permitió encontrar los primeros nidos activos descritos para el Águila Arpía en Perú e indicarían una cierta preferencia para anidar en castañales. Así mismo, la información recogida ha permitido establecer que el área de anidamiento de una pareja de Águilas Arpía en la zona de estudio es de aproximadamente 4300 hectáreas. El análisis de los restos de las presas consumidas y de las egagrópilas recolectadas dentro y alrededor de la base de los nidos nos han permitido hacer una primera descripción de la dieta de la especie, la cual está compuesta principalmente por mamíferos arbóreos.

Resource availability and diet in Harpy Eagle breeding territories on the Xingu River, Brazilian Amazon

“…Armadillos in the Harpy Eagle diet have been reported in the mosaic of Protected Areas of Carajás, Para state (Aguiar-Silva et al, 2012), at the Serra da Bodoquena National Park, Mato Grosso do Sul , in the Brazilian Cerrado, at Barra do Bugres, Mato Grosso state (Rosa, 2012) and in Peru (Piana, 2007). Occurrence of species restricted to or associated with riverine habitats (Remsen and Parker III, 1983), such as the hoatzin and common iguana, indicate that the pair is foraging in riparian areas.…”

“…Several studies over the wider Neotropics have reported on the composition of Harpy Eagle diet (Fowler and Cope, 1964;Rettig, 1978;Álvarez-Cordero, 1996;Galetti and Carvalho Junior, 2000;Sanaiotti et al, 2001;Piana, 2007;Muñiz-López et al, 2007;Anfuso et al, 2008;AguiarSilva et al, 2014a), and sloths are the main prey species (Aguiar-Silva et al, 2014a). One compared prey species use in relation to availability by standardized method in data collection (Galetti and Carvalho Junior, 2000), but no one has yet included data sets from fauna rescue/flushing counts.…”

Phylogenetic Relationships of New World Porcupines (Rodentia, Erethizontidae): Implications for Taxonomy, Morphological Evolution, and Biogeography

“…openly displaying such weapons might be advantageous for deterring attacks by predators that kill by biting (e.g., felids; Emmons, 1987;Moreno et al, 2006), which must often result in a painful (or even lethal) mouthful of spines. on the other hand, hiding quills under a long, thick coat of background-matching fur might be advantageous for avoiding detection by predators that kill with armored talons (e.g., harpy eagles; Izor, 1985;Piana, 2007), against which spines might be ineffective. unfortunately, evidence of taxonomic variation in habits that expose porcupines to different sets of predators is almost entirely anecdotal, consisting of chance observations (e.g., fig.…”

Translocation of Harpy Eagle (Harpia harpyja) (Linnaeus, 1758) nest

“…The nests, measuring up to 2 m in diameter, are built by the breeding pair together using thick twigs, in trees 50-70m high emerging from the canopy (Del Hoyo et al, 1994). The position chosen for the nest is usually the main branch of a tree at a height ranging from 25 to 35 meters (Piana, 2007). According to Alvarez-Cordero (1996), each breeding pair is linked to a territory centred on the nests, enabling one to calculate the mean breeding area for a pair.…”
