Remarks. — The young and adults in fall plumage are known as Eeed- 

 birds. Adults acquire this plumage by a complete molt after the breeding 

 season. The breeding plumage is regained by a complete molt in the spring, 

 and not, as has been supposed, by a change in the color of the feathers with- 

 out molting. Freshly plumaged males have the black veiled by yellow tips 

 to the feathers ; these gradually wear off, and by June have almost entirely 

 disappeared (of. Chapman, Auk, x, 1893, p. 309). 



^onj'e.^Breeds from southern New Jersey northward to Nova Scotia, 

 westward to Utah and northern Montana ; leaves the United States by way of
