- Abstract
Identification of threats contributing to occurrence and range distribution of avifaunal communities is poorly known in diversely urbanized landscapes of the Bengaluru city, south India. For the first time, we investigated the disturbance scores along the low (LDS) to high disturbance sites (HDS) with respect to various parameters, i.e. canopy cover, vegetation structure and its composition. We examined their habitat associations and the potential effects on them corresponding to various threats including human development pressure and other habitat suitability indices in urban landscapes of the Bengaluru region. HDS with a lower number of bird species harbour more threat scores than the LDS with the highest number of bird species. Habitat alteration, practice of monoculture plantations, improper waste management and grass cutting were more commonly observed threats in landscapes of the Bengaluru region. The maximum number of perching plant species was characteristic of low disturbance sites with a greater fraction of moist deciduous species. Canopy coverage of plants/trees and the structure of canopy cover were the highest in LDS with the highest strata of the vegetation cover. Human development pressure was the highest in HDS. Management further includes several approaches for the maintenance of urban landscapes for avian communities to minimize bird problems and promote management options that favour bird diversity.
