We evaluated the taxonomic and functional diversity of birds in a rural landscape in the north-eastern Andes of Colombia. We carried out seven field trips and used transects of 300 m, separated from each other by 500 m in the dominant plant cover of the rural landscape. We measured alpha (α) and beta (β) diversity at both the taxonomic and functional levels. We registered 10 orders, 21 families, 56 genera and 63 species of birds. In wooded pasture, we recorded 55 species and a relative abundance of 66% and 44 and 34% for an Andean forest fragment. The species that contributed the most to the dissimilarity between the covers were Zonotrichia capensis, Turdus fuscater, Mecocerculus leucophrys, Atlapetes latinuchus and Crotophaga ani. We identified nine functional types, where G1 was made up of small species with anissodactyl and pamprodactyl legs that were insectivorous, frugivorous and nectarivorous as the best represented. The FEve and FDiv were 0.51 and 0.74, respectively in the Andean forest fragment plant cover and, for the wooded pasture, the FEve was 0.45 and the FDiv was 0.81. Both cover types contributed to the diversity of the rural landscape and the dynamics that existed between them formed a complementary factor that favoured the taxonomic and functional richness of the characterised rural landscape.

The diversity of birds in the Las Quinchas mountain range amounted to 374 taxa in 2007, most of them distributed in the tropical region of the massif. We made five sampling trips between March and October 2019 to different locations in the Tropical and Sub-Andean regions of Las Quinchas, we added 11 species increasing in 3% the avian richness of the mountains. The 383 species are distributed in 55 families and 22 orders. One species is categorized as Critically Endangered and four are the Vulnerable. There was greater species richness in the upper part of the mountains and low turnover between altitude ranges.
