the wearing away of the edges to the feathers that the head is left 

 grey in its first summer plumage. 



The old birds in lu Inter plumage are distinguished from the young 

 hy their olive-yellow back and yellow under surface. I have not 

 found an old l)ird moulting from its winter to its summer dress, as 

 the young bird most certainly docs ; and I believe that the spring 

 moult is confined to the first year's bird, and that the old ones attain 

 their full plumage by wearing oft' the margins to the feathers, which 

 in course of time become much brighter. This opinion is corrobo- 

 rated by the fact that many of the blue-headed birds on their first 

 arrival in Europe have a little olive on the crown, remains of winter 

 plumage. 



In breeding-plumage the feathers get rather worn and the ear- 

 coverts somewhat blacker, the white eyebrow, however, being always 

 very distinct. 



Jfah. Europe generally in summer, wintering in Africa. An 

 eastern colony extends from Alaska and Northern Siberia to China, 

 wintering in the Moluccas.
