Abstract

Amazonia is undergoing rapid urbanisation, but nothing has been published on the structure and function of urban Amazonian avifaunas. Here we present the results of a year-long survey of the avifauna of an Amazonian city, exploring temporal variation in its taxonomic, phylogenetic and functional diversity. We found urban bird communities to be taxonomically depauperate and dominated by a small subset of common species typical of second growth and river-edge habitats. Broad patterns of phylogenetic community similarity typically resembled those found in other studies on urban Neotropical bird assemblages, with insectivores the dominant guild. There was significant temporal variation in taxonomic and phylogenetic structure owing to the seasonal arrival and departure of a regionally over-represented minority of migratory species. Although the urban avian assemblage is of limited regional conservation value, it may still offer significant biodiversity services and represent one of few points of contact for local people with biodiversity.
