Abstract

Breeding performance of the Black Crowned Night Heron- (Nycticorax nycticorax) was studied in Ahmedabad, Gujarat during January 2015 to December 2015. The population of Nycticorax nycticorax was observed in wetlands of the study area. During study period 21 nests were seen. Breeding period starts from July and extend up to September 2015. Black Crowned Night Heron mostly preferred the large leafy trees for nest building. Different species of plants were preferred for nest building by this bird species. Success of Hatching 62%, success of Nestling 56% and success of Nesting 35% was observed. Low breeding success of Nycticorax nycticorax was observed. Predation, food availability, heavy rainfall, high wind velocity was the reasons for the low performance of breeding.
