MENESES ORTEGON, LUZ ANDREA  y  HERRERA-MARTINEZ, YIMY. PRELIMINARY STUDY OF BIRD LIFE ASSOCIATED TO Polylepis quadrijuga (Rosaceae) PATCHES FROM "LA RUSIA", MOORLAND IN DUITAMA (BOYACÁ-COLOMBIA). Luna Azul [online]. 2013, n.36, pp.40-54. ISSN 1909-2474.

During 2007 a preliminary characterization of bird life present in the patches of Polylepis quadrijuga at "La Rusia" moorland, Duitama (Boyacá - Colombia), was carried out comparing two climatic seasons and three patches The patches were chosen according to their vegetation physiognomic similarity, interpretation of aerial photographs and field work. Sampling of bird life was carried out in each season and each patch through direct observation of birds in the morning and afternoon and through capture using mist-nets. Data obtained determined the bird species richness, and a multivariate analysis was made taking into consideration the species, the season and patch sampled.. Thirty-four species of birds grouped into 29 genera and 13 families were found from which Trochilidae and Emberizidae, were the richest. Six bird species were common to all three patches and patch number 3 showed the highest species richness (20), probably because this patch makes an ecotone with the high Andean forest, it is the largest (7 ha) and it is crossed by a stream. The three patches provide bird species to the overall ecosystem composition.
