YELLOW-HEADED WAGTAIL. 
males and females have no black cross on the occiput 
after the autumn moult. 
The distinctive characters of the female have been 
already noticed, and will be further observed in my 
figure, which is an adult female in summer plumage, 
after Middendorff. 
Figured by Gould, pi. 144; Middendorff, Sibirische 
Reise, ii., pi. 14, fig. 4.
