pecially in the malar regions Bill and feet dusky pinkish buff, the bill be- 

 coming slaty (except flesh-color at base of lower mandible), the feet becoming 

 grayish black. 



3. First Winter Plumage acquired by a partial postjuvenal 

 moult, beginning the end of July in eastern Canada, which in- 

 volves the body plumage but not the wings nor the tail, young 

 and old becoming practically indistinguishable. 



Similar to previous plumage. Above, a darker bluer plumbeous gray, the pileum 

 and transocular stripes glossy black, the superciliary lines, sides of head and 

 chin clear white without speckling. Below, rich tawny ochraceous buff, deepest 

 on the sides and crissum, the under tail coverts terminally white. 



4. First Nuptial Plumage acquired by wear, the fading 

 so marked that breeding birds resemble those in ju venal dress. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult in July. Practically indistinguishable from first 

 winter. 



6. Adult Nuptial Plumage acquired by wear as in the young 

 bird. 



Females. — The plumages and moults are similar to those of 

 the male. In juvenal plumage the pileum is largely plumbeous

 paler. In later plumages the cap never becomes as black as 

 that of the male.

 a dingy white area on the outer webs of the lateral pairs. Below, dull white,

 eye and auriculars deep mouse-gray. Bill and feet pale sepia-brown becoming
