Grey Partridge calling loudly from atop a rock! 

Grey Partridge of teetar (Francolinus pondicerianus) of India. Listen to its lovely call (by which it gets its Indian name - teetar!)
The Grey Francolin (formerly also called the Grey Partridge, but not to be confused with the European Grey Partridge) Francolinus pondicerianus is a species of francolin found in the plains and drier parts of South Asia. They are found in open cultivated lands as well as scrub forest and their local name of teetar is based on their calls, a loud and repeated Ka-tee-tar...tee-tar which is produced by one or more birds. The term teetar can also refer to other partridges and quails. During the breeding season calling males attract challengers and decoys were used to trap these birds especially for fighting.
