grey francolin
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.
