Remark*. The youn/ and adults in fall plumage are known an Reed- 

 l>ir.U. 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 -u;. ]...-..!, by a change in the color of the feathcra 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, 1898, p. 809). 



Rungt. Breeds from southern New Jersey northward to Nova Scotia, 

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

 Flori<la, and winter* in South America.
