The large-billed reed warbler (Acrocephalus orinus) really seems to be coming out of the woodwork. After the finding in Thailand, another specimen was discovered in the collection of the Natural History Museum at Tring, in a drawer of Blyth’s Reed-warblers, specimens collected in India in the 19th century.
Now another sighting has been reported from Narendrapur Sanctuary, though still unauthenticated. The full story's here.
