The chukar partridge (Alectoris chukar), or simply chukar

INTERESTING THINGS ABOUT THIS BIRD : 

The chukar is a rotund 32–35 cm (13–14 in) long partridge, with a light brown back, grey breast, and buff belly. The shades vary across the various populations. The face is white with a black gorget. It has rufous-streaked flanks, red legs and coral red bill. Sexes are similar, the female slightly smaller in size and lacking the spur. The tail has 14 feathers, the third primary is the longest while the first is level with the fifth and sixth primaries.

It is very similar to the rock partridge (Alectoris graeca) with which it has been lumped in the past^[4] but is browner on the back and has a yellowish tinge to the foreneck. The sharply defined gorget distinguishes this species from the red-legged partridge which has the black collar breaking into dark streaks near the breast. Their song is a noisy chuck-chuck-chukar-chukar from which the name is derived.^[5] The Barbary partridge (Alectoris barbara) has a reddish-brown rather than black collar with a grey throat and face with a chestnut crown.^[6]

The Chukar is used to the national symbol of Pakistan. In North Indian and Pakistani culture, as well as in Indian mythology, the chukar sometimes symbolizes intense, and often unrequited, love. It is said to be in love with the moon and to gaze at it constantly. Because of their pugnacious behavior during the breeding season they are kept in some areas as fighting birds. In short, Chukar partridge have a huge reason to be the National bird symbol of Pakistan.
