Perdix dauurica

The Daurian partridge, also known as the steppe partridge, Asian grey partridge or bearded partridge, is a rotund gamebird 28–30cm long. Its name derives from the Dauria region of Russia, which forms part of its range. Chicks are pale yellow-brown dappled with dark brown and rufous (Wikipedia, general species account).

It breeds on open grassland, steppe and farmland across much of temperate East Asia, from Kyrgyzstan east to China and Mongolia. The nest is lined with grasses and twigs on the ground under a bush or in tall grass, with a typical clutch of 13–20 olive-brown eggs. Chicks can fly short distances at about two weeks. The song is a higher-pitched, sped-up version of the grey partridge's (Wikipedia, general species account).
