Darter - Photograph by Ron Saldino

Darter (Anhinga melanogaster), also called Snake Bird (Anhinga rufa), is a scarce breeding resident in Haryana. It is found in the wetlands. Chiefly feeding on fish, its habits are quite similar to those of the Cormorants. The yellowish dagger like bill and the long snake like neck are its main identifying features.
