GREY-HEADED WAGTAIL. 417 
The young male in his first autumn plumage resembles 
the adult female in the breeding-season, except that the 
grey of the head is more mixed with brown, and the yel- 
low of the upper part of the breast is clouded with brown 
and buffy orange. In the following spring the grey fea- 
thers of the head still exhibit a slight mixture of olive- 
green, and the chin is yellow, which in the more adult 
male is white. 
The young female in spring has the head and ear- 
coverts greyish brown; the chin and throat buffy white ; 
the upper part of the breast mottled with brown; the 
lower part of the breast, and the other under parts, prim- 
rose yellow, enriched with a mixture of king’s yellow. 
This bird may be distinguished from our common sum- 
mer Yellow Wagtail, MW. Rayi, next to be described, by 
the white elongated line over the eyes and ear-coverts, 
which appear to be permanent at all seasons, and by the 
grey head, which is more or less conspicuous, also, at all 
seasons, but particularly in summer. In Ray’s Wagtail, 
the line over the eye and the ear-coverts is yellow; and 
the head, I believe invariably, of the same colour as the 
back of the bird. The females of the two species most 
resemble each other.
