Características de la avifauna en un gradiente altitudinal de un bosque nublado andino en La Paz, Bolivia

摘要: This study analyzes the diversity and composition of birds at three locations within National Park Natural Area Integrated Management Cotapata, La Paz, Bolivia. The were distributed in altitudinal gradient Andean rainforests (ceja de monte -Cloud forest ridges- to 3170 m, cloud 2620 m secondary 1850 m) Yungas area. We make a total effort 3282 mist, 324 random walks hours 216 point counts sites. A 220 species recorded, most caught nets (100 spp., 45%). Twenty-five families represented catches by mist net 42 through censuses. Tyrannids Thraupids more representatives both methods. Species cumulative curves similar all sites with major number census data. richness elfin forest, based on netting data count was 44, 40, 44 69, 57, 86 species, respectively. 16 restricted range registered (e.g. Odontophorus balliviani, Andigena cucullata). Diversity for ridges H´= 1,41; (H´= 0,98) 0,96). Beta 0,74 0,79 from elevations.
