This book reports the breeding ecology and conservation of the bank myna (ACRIDOTHERES GINGINIANUS) carried out between June 2007 and October 2009 in Chapai Nawabganj District of Bangladesh. The total population in the breeding colonies was estimated to be 4,452. The species mostly made holes in the eroded riverbanks and earth heap of brickfields during February to April and laid eggs during late April to early July. The incubation period was 15-17 days in 2009 and 18-19 days in 2008 (overall mean 16.6 days), and fledging period was 22-25 days in 2009 and 23-25 days in 2008 (overall mean 23.49 days) after hatching. According to the number of eggs laid, the hatching success was 80.67% in 2009 and 79.12% in 2008 (mean 79.9%), and the breeding success was 61.5% in 2009 and 61.11% in 2008 (mean 61.41%). The environmental and human impacts on the breeding colonies and future plan about conservation awareness of the species have been discussed.
