Abstract
The population density of Red-vented Bulbul Pycnonotus cafer was studied in three different habitats in a portion of Cauvery delata region of Tamil Nadu, between 2011 and 2013. Regardless of habitats and years the bulbul density varied from 16 to 51 birds per km2. Among the habitats the river banks supported relatively high number of birds than other habitats. Moreover, within habitats the population of bulbuls varied among seasons and summer supported relatively higher number of birds. Yearly variations of density showed that year 2013 had highest densities.
