In this report, we provide information on food plants of the equatorial saki (Pithecia aequatorialis) and its competitors in highland forest of the micro-watershed of the Itaya River, Peruvian Amazonia. From May to November 2009 and from January to April 2010 we followed silently two family groups with the purpose to identify plants whose fruits are part of their diet. During the contacts we had 90 food events in 48 plant species grouped in 24 families. Of these, 36 live in low hill forest and the rest in high terrace forest. The highest diversity of food plants is grouped into seven families that together accounted for 60.4%, among them Moraceae (8 species), Fabaceae (6 species) and Annonaceae (4 species) families. The fruits were mostly eaten in ripe state, being the mesocarp the most appreciated (40%). Among mammals, seven of the competitors were primates, with the main competitor bei...

En este reporte proporcionamos información sobre plantas alimenticias del huapo negro (Pithecia aequatorialis) y sus competidores en bosque de altura de la microcuenca del río Itaya, Amazonía peruana. De mayo a noviembre del 2009 y de enero a abril del 2010 seguimos silenciosamente a dos grupos familiares con el propósito de registrar las plantas cuyos frutos forman parte de su dieta. Durante los contactos tuvimos 90 eventos alimenticios en 48 especies de plantas agrupadas en 24 familias. De ellas, 36 habitan en bosque de colina baja y el resto en bosque de terraza alta. La mayor diversidad de plantas alimenticias está agrupada en siete familias que en conjunto representaron el 60.4%, sobresaliendo entre ellas las familias Moraceae (8 especies), Fabaceae (6 especies) y Annonaceae (4 especies). Los frutos en su mayoría fueron consumidos en estado maduro, siendo el mesocarpio el más...
