PASSERINE BIRDS OF NEW YORK 257 



Female. — The females have corresponding plumages and 

 moults. Even in juvenal plumage a difference from the male 

 can be observed in the dull brown wings and tail with greenish 

 instead of bluish edgings, and the white area at the bases of the 

 primaries is dingy and sometimes absent. In first winter plu- 

 mage the bird is oliv^e-green above, and yellowish buff below ; 

 the wings and tail olive-brown, the latter without white blotches, 

 the superciliary line and the lower ej^elid are buffy-white ; the 

 lores and auriculars are a dull drab. The first nuptial plumage 

 is acquired apparently wholly by wear, which makes the bird 

 grayer above and whiter below. The adult winter plumage is 

 bluer above than the first winter, especially on the head, lesser 

 coverts and wing edgings, and paler below, the tail showing traces 

 of dingy blotches on the lateral rectrices. The white area of the 

 primaries is larger and whiter. The lores and auriculars are 

 dusky. The adult nuptial and later plumages are very similar 

 to the adult winter. 



I am of the opinion that the southern race described as cairnsi 

 may prove to be untenable, as the blackness of the back might 

 easily be due to age rather than locality. 



Dendroica coronata (Linn.). Myrtle Warbler 



1. Natal Down. No specimens seen. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, the feathers centrally dull black, edged with drab and buffy brown, produc- 

 ing a streaked effect. Below, much whiter but similarly streaked, a tinge of pale 

 primrose-yellow on the abdomen. Wings and tail dull black, edged with drab, 

 palest dn primaries and outer rectrices. Two very indistinct buffy white wing 

 bands. Upper and lower eyelids with dull white spots. Bill and feet dusky 

 pinkish buff, the former becoming black, the latter deep sepia. 



Birds at this stage (see Aiik, XVI, 1899, p. 217, plate III), 

 bear a striking resemblance to the young of Spiniis piuus. 



3. First Winter Plumage acquired by a partial postjuvenal 

 moult, in August in eastern Canada, which involves the body 

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

 tail.
