Dupetor flavicollis
Range
Tropical Asia from Pakistan, India, Bangladesh and Sri Lanka east to China, Indonesia and Australia
The black bittern (Botaurus flavicollis) is a bittern of Old World origin, breeding in tropical Asia from Pakistan, India, Bangladesh and Sri Lanka east to China, Indonesia and Australia. It is mainly resident, but some northern birds migrate short distances. It was formerly placed in the genus Ixobrychus, which a 2023 molecular study of the heron family found to be paraphyletic and merged into Botaurus. (Wikipedia, general species account)
