Adult Male (Sartchy, May 24th). Upper parts pale hair-brown, the middle of the dorsal feathers darker; 

 rump and upper tail-coverts rose-red ; quills dark brown, externally margined with white, washed with 

 rose ; secondaries more broadly margined and broadly tipped with white ; larger and median wing- 

 coverts broadly margined with buffy white and rose-red ; tail dark brown, the feathers margined with 

 buffy white ; underparts generally buffy white, washed with rose-red : bill yellowish brown ; legs light 

 brown j iris dark brown. Total length about 5"5 inches, culmen 045, wing 3'5, tail 2'25, tarsus 07. 



Adult Female (E. Turkestan, June). Differs from the male merely in being rather duller in colour and 

 being less rose-tinted. 



In the autumn dress the light margins to the wing- and tail-feathers are broader, the back is rather paler 

 and more uniform in colour, the dark centres to the feathers being less apparent, and the underparts 

 are less tinged with rose-colour and are whiter. According to Severtzoff, in the full spring plumage 

 all the rose-coloured feathers become blood-red, and the whitish has changed to a snowy-white colour, 

 except on the stomach and under tail-feathers, which are protected from the sun. The rose-colour is 

 brightest on the wings, paler on the throat, breast, superciliary region, flanks, and rump, where only 

 the margins of the feathers are of that colour. The dark lines on the crown and back become darker 

 in the spring, and the grey margins to the feathers are lost. 



The young male in the first autumn resembles the adult female, but has no white margins to the larger 

 wing-coverts, which are brownish red, and the median coverts have very narrow white margins, which 

 do not form a white spot when the wings are closed. 



The young female in the first autumn has scarcely any red in the plumage, this colour being replaced by 

 light grey, which is faintly washed with rose on the breast.
