 toes with blackish, and soles with reddish ; iris dark brown.' {Stejneger.) 



''The exact method by which the rufous chest of the summer plumage 

 is gained is not easy to discover. In some specimens in winter dress 

 there is a distinct narrow line of brown across the fore neck; in most of 

 the series of skins in the Museum this is wanting, as it is also in young 

 birds. It may therefore be a sign of very old birds only, as there are 

 traces of brown feathers in an old bird which has not quite attained its 

 full summer plumage. In the specimen in question it is also evident that 

 tlie rufous breast is being acquired by a change of color in the feather, 

 from brown to rufous, as well as by a molt. Probably only very old birds 

 go through this double process, as in the majority of specimens the 

 rufous breast appears to be gained by a molt only. Wlien first devel- 

 oped all the rufous feathers are edged with white. 



"A young bird is described by Dr. Stejneger as somewhat resembling 

 the adult: 'Tbe brownish gray of the back is paler, and each feather 

 narrowly edged with isabella-color, with which also the lower parts are 

 suffused. On the pectoral region a huffish tinge replaces the rufous collar, 

 and the black markings are absent from tbe head, the cheeks and ear- 

 coverts being slightly dusky; the forehead between the bill and the eyes 

 whitish, suffused witli isabella-color.' 



''The winter plumage and young livery of the western and eastern 

 forms of 0. mongolus are, as might have been expected, very difficult to 

 distinguish, l)ut the western fonn seems always to have a longer tarsus 

 (about 3'^ mm.), whereas the eastern form has the tarsus al)out 2S mm."
