The study area includes the northern part of the city of Bogota and adjacent rural areas, as well as several mountain ridges reaching elevations between 2800 and 3100 m. Its center at 4º48N, 73º11W. The area includes a variety of habitats including urban parks, rural areas with crops and pastures, natural and artificial wetlands of different sizes and surroundings, natural and planted forests (mostly Eucalyptus) and secondary scrub. We used the Audubon´s Christmas Bird Count methodology in which for a period of 24 hours between approximately December 14 and January 5, parties (groups) of bird watchers identify and count all birds they can detect in a 15 mi diameter circle (24.1 km) with a fixed center. We followed this methods for 26 years between 1989 and 2014. A total of 29 plots were visited over the course of the study with variations each year between 7 and 19. We standardized sampling effort by dividing the abundances of every species by party-hours per sampling event (year-plot).Citation(s)
