- Abstract
The urban green spaces are emerging habitats for biodiversity, which respond to changes in urban landscapes. Psittacidae (parrots, parakeets, and macaws) represents a family of conspicuous birds that are common in tropical cities, where they use anthropogenic resources and emerging habitats. We aimed to evaluate how local distribution and the abundance of Psittacidae species change in a city of northern Andes of Colombia (Medellín; 6°15'N, 75° 34'W, ca. 1400-2000 masl) across an urbanization gradient determined from the percentage of impervious surfaces, based on supervised classification methods with satellite imagery. We counted birds at 10 sites in four to five visits along a 1 km transect for 1 hour each, between 06:00-10:00 h; total sampling effort was 45 h from September 2021 to February 2022. We recorded 181 birds of 8 species of Psittacidae along the gradient, with Brotogeris jugularis (72) and Forpus conspicillatus (42) being the most abundant species. F. conspicillatus was less abundant towards sites with more percentage of impervious surfaces, whereas B. jugularis showed the opposite response. Other species such as Amazona amazonica also showed a positive response to increasing percentage of impervious surfaces, whereas other species such as Ara spp. were rarely detected. Amazona ochrocephala and Eupsittula pertinax showed ambiguous responses, with relatively high abundances toward sites with contrasting percentages of impervious surfaces. F. conspicillatus, B. julugaris and A. amazonica by showing a clear and differentiated response to the percentage of urbanization, as well as also being easy to recognize, may be useful as bioindicators species in community science exercises.
