The Harpy Eagle (Harpia harpyja Linnaeus) is the biggest raptor that inhabits the Amazonian rainforest, however, in Perú, little is known about the biology of the species. Since 1996 to 2001, a research on the nesting characteristics and diet of the Harpy Eagle was conducted in the Native Community of Infi erno, through the localization and observation of active and abandoned nests. This research has found the fi rst active nests reported for H. harpyja in Peru and its probable preference to nest in Brazil nut trees stands. The data collected showed that the nesting area for a couple of eagles in the study area is of approximately 4300 hectares. The analysis of prey remains and casts collected inside and under the nests allowed the fi rst description of the diet H. harpyja, which is mainly composed of arboreal mammals.

Entre el 19 y 23 de noviembre del 2000, y en el marco del curso “Uso de inventarios biológicos para revelar patrones de distribución geográfica de especies en la selva baja amazónica”, organizado por el proyecto DiversidadBiológica de la Amazonía Peruana, Perú - Finlandia (BIODAMAZ), con el apoyo del Instituto de Investigaciones de la Amazonía Peruana (IIAP) y la Universidad Nacional de la Amazonía Peruana (UNAP), fueron realizadas evaluaciones de la diversidad de especies de aves en la Zona Reservada Allpahuayo - Mishana (ZRAM), y en las colinas de la Formación Nauta, Loreto. Se evaluó la presencia de especies de aves en diferentes formaciones vegetales (varillal, colinas de la Formación Pebas en la ZRAM, incluyendo unas colinas de arena blanca, y unbosque de colina en la Formación Nauta), utilizando los métodos de transecto lineal y puntos de conteo.

We present the record of an individual of northern tamandua (Tamandua mexicana) with abnormal white coloration that was photographed with a camera trap in the equatorial dry forest in the department of Lambayeque, at elevation of 560 m, northwest Peru. We could not determine if this chromatic aberration was a case of leucism or albinism, but we highlight this uncommon record as the first for Peru. We also revised the information about its presence in the southern portion of its global range.
