The Yanachaga-Chemillén National Park is located in the central jungle of the Peru, in the department of Pasco, province of Oxapampa and the districts of Oxapampa, Pozuzo, Villa Rica and Palcazu. Its surface is 110658.25 Ha
(122000 Ha according to the Supreme Decree that established it).
The extension of this National Park is on the Yanachaga mountain, the same that belongs to the western Andean slope. The dominant landscape of Park are the mountains covered by forests and furrowed by deep cannons. The altitudinal variation is remarkable, ranging from 460 to 3643 meters above sea level. This altitudinal gradient, added to its climatic variety, generates a high variety of ecological formations in a relatively geographic space small, with a consequent high biological diversity. It is also considered to the Park area as a “Pleistocene refuge”, which means that it is an area that conserved wooded relics when in the geological period of the Pleistocene most of the areas occupied by Amazonian forests were occupied by herbaceous ecosystems, as a consequence of severe
Birds are an integral part of the mountain forest ecosystems that it has the Yanachaga-Chemillén National Park. They are the best known group in its ecological and taxonomic aspect, due to the ease of techniques for its
evaluation and monitoring. Likewise, in Peru, investigations to determine their ecology, ranges of distribution,
sensitivity and therefore can be considered to assess the conditions ecological conditions of a given area. Peru is the second country with the highest diversity of birds in the world, with 1815 species representing 18.5 approximately percent of all birds on the planet and 45% of the
Neotropical species. Birds in Peru are present in different ecosystems due to the variety of microclimates that the

The purpose of this work was to collect the information, field and cabinet, on the diversity of birds in the National Park Yanachaga Chemillén and its buffer zone .
