ABSTRACT
Nests, egg, clutch size and hatchlings of red vented bulbul were observed from January, 2017 to December, 2019. During the observation we recorded 16 nests. Out of them 62.50% nests were observed with 3 eggs and 37.50% nests with 2 eggs. Total 42 eggs were recorded during study period. Out of 16 nests eight (50%) nests had eggs and hatchling while remaining eight (50%) nests had only eggs. Number of hatchling depends upon size of clutch. Egg laying and hatchling are directly related with environmental factors like availability of nesting material and food in breeding season. Food plays vital role for new born and adults survival.
