204 DWIGHT 



The description is from two specimens secured by me in New 

 Brunswick, Canada, July I2th, with tails about one-third 

 grown. 



3. FIRST WINTER PLUMAGE acquired by a partial postjuvenal 

 moult in August in eastern Canada which involves the body 

 plumage and the wing coverts but not the rest of the wings nor 

 the tail. 



Extremely like the previous plumage but with a greenish tinge above, the edgings 

 and median crown stripe paler. Below, whiter, the throat band deep pinkish 

 buff, a like tint on the malar bands which are bordered by black rictal and 

 submalar streaks, the sides, flanks and crissum grayer buff. The streaking s 

 below are narrow and black, merely flecking the white chin and not reaching 

 the white of the breast and abdomen. The superciliary line is deep olive-buff 

 extending on the sides of the neck. 



4. FIRST NUPTIAL PLUMAGE acquired by wear which produces 

 very little effect. Birds become slightly grayer and of a paler 

 brown above and the streakings below are a little more promi- 

 nent, the buff fading a little. 



5. ADULT WINTER PLUMAGE acquired by a complete post- 

 nuptial moult in August. Practically indistinguishable from first 

 winter dress, the tertiary edgings perhaps darker and all the 

 colors richer. 



6. ADULT NUPTIAL PLUMAGE acquired by wear as in the 

 young bird. 



Female. The sexes are practically indistinguishable in all 

 plumages, and the moults are the same in both sexes. 



Melospiza georgiana (Lath.). SWAMP SPARROW 



1. NATAL DOWN. Sepia-brown. 



2. JUVENAL PLUMAGE acquired by a complete postnatal moult. 



Similar to M. fasdata but darker especially on the crown, more washed with buff 

 below and more narrowly streaked with deeper black on the throat. 



Above, cinnamon-brown, dull chestnut on the crown, streaked with black. No ob- 

 vious median crown stripe. Superciliary line olive-gray duskily spotted. 

 Wings and tail black, edged largely with chestnut, the wing coverts and ter- 

 tiaries paler. Below, dull yellowish white washed with deep buff on sides of 

 chin, across jugulum, on sides, flanks and crissum and narrowly streaked with 

 black except on the chin and mid-abdomen. Bill and feet pinkish buff, the 

 former becoming dusky, the latter sepia-brown.
