Abstract
A
study was undertaken to know the abundance, diversity and species richness of
bird communities in urban landscapes of Bengaluru region, India. One hundred
and eighteen species of birds belonging to 43 families under 78 genera was
documented. Of them, Gyps indicus, Neophron percnopterus and Parus
nuchalis were critically endangered, endangered, and vulnerable species.
Among 19 landscapes, the mean population density (number of birds seen/km2)
was highest at Bannerghatta National Park and lowest at Kempegowda Bus
Station. Species diversity, species evenness and richness of bird communities
were significantly different between landscapes. Seasonal occurrence of bird
species was not significantly different. The mean population density of birds
was positively correlated with tree density and negatively correlated with
canopy coverage, human population density and buildings.
