lemon-yellow. Vouiig may be distinguished usually by the dusky inner margins 

 of the tertiaries but differ very little from adults. 



4. FiR.sT Nuptial Plumage acquired by wear which removes 

 much of the wing edgings. Browner more worn remigcs and 

 especially primar\' coverts with distinct edgings distinguish young 

 birds. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult. Differs little from first winter dress, but fewer 

 edgings, and blacker primaries with their coverts and the ter- 

 tiaries white. 



6. Adult Nuptial Plumage acquired by wear. 



Female. — The moults and plumages correspond to tho.se of 

 the male but the colors and markings are quite different. The 

 sexes are similar in ju venal plumage. In first winter dress 

 females are deep mouse-gray about the head, paler on the back 

 and grayish wood-brown on the rump. The primaries have a 

 white spot at their bases and the secondaries and tertiaries are 

 wholly drab-gray with dull black on the inner webs. The tail 

 has the inner webs of all the rectrices white and the upper tail 

 coverts have white s[)ots. The first nuptial plumage is assumed 

 b}- wear and the adult winter dress by a complete moult, this 

 plumage being rather grayer than that of the first winter.

 especially on breast and sides, with ochraceous, the feather edgings wood- 

 brown. Bill and feet dusky pinkish bufi' becoming darker with age. 



3. P^iRST Winter Plumage acquired by a partial postjuvenal 

 moult beginning early in September in eastern Canada which
