Methods

The study area is a forest reserve property of the Bogota Aqueduct and Sewage Company in the western buffer zone of Chingaza Natural Park in the eastern Andes of Colombia. Elevation ranges from ~2830 m to 3020 m. The area is covered by cloud forest with a 20-25m canopy and a high density of epiphytes. Dominant trees include Weinmannia spp., Clusia spp., Symplocos sp., Hieronyma sp., Brunellia sp., and several species of Lauraceae. The understory includes shrubs, small trees, and hemiepiphytes as well as areas dominated by bamboo (Chusquea sp.) and Geonoma weberbaueri (a small palm). In the fist study we visited the study area eleven times monthly between October 1991 and July 1992. In each visit we set mist nets to capture, measure and band birds for two consecutive days. Each day nets were set singly or in groups of up to four in different parts of the area, along different sectors of 3km of study trails and were opened each day from ~06:30 to 11:00, except during rainy intervals, for a total of 1232 mistnet hours (1 mistnet hour= 1 12m mistnet open for 1 hour).In the second study we visited the study area in six occasions at two month intervals from June 2015 to May 2016 and also set mist nets for two consecutive days following the same procedure of the first study, along 2 km of study trails wherever topography and vegetation permitted, but permitting coverage of all characteristic habitats and vegetation types. We set up 15 12-m nets and five 6-m nets (equivalent to 17.5 12-m nets) each day. Overall, we accumulated 804 total net-hours in this second study. Capture data was aggregated by year (as captures per sampling period for 1991/1992 samplings were not provided) and abundance was standardised to be captures per 1000 mist-net hours.
