PASSERINE BIRDS OF NEW YORK 267 



streaks, the crown and auriculars distinctly black, veiled with 

 orange tips, the streaking below heavier and broader, the wings 

 and tail blacker and the edgings grayer. 



6. Adult Nuptial Plumage acquired by a partial prenuptial 

 moult as in the young bird. Two specimens, apparently adult 

 males judging from blackness of the primaiy wing coverts and 

 other characters show this moult. One Am. Mus. Nat. Hist., 

 No. 39748, from Bogota, Colombia, shows many feathers in 

 their sheaths; with No. 30330 from Quito, Ecuador, the moult 

 is less advanced. 



Female. — The plumages and moults correspond to those of 

 the male. In juvenal plumage the wing edgings are usually 

 duller the first winter plumage being similar to that of the male 

 but browner, the yellow tints nearly lost and the streakings ob- 

 scure and grayish. The first nuptial plumage assumed by a 

 more or less limited prenuptial moult, is grayer above and paler 

 below, except on the chin and throat where new pale orange 

 feathers contrast with the worn and faded ones of the breast. 

 The adult winter plumage is practically the same as the male 

 first winter, the auriculars and transocular stripe usually duller. 

 The adult nuptial plumage is brighter below than the first nuptial 

 and with more spotting on the crown, but the black head and 

 bright orange throat of the male are never acquired.

2. Juvenal Plumage acquired by a complete postnatal moult.

plumbeous gray, the tertiaries with olive-gray. Outer rectrices with white spots.

3. First Winter Plumage acquired by a partial postjuvenal 

 moult, early in June in Florida, which involves the body plumage 

 and wing coverts, but not the remiges nor rectrices. 



Above, smoke-gray veiled with sepia-brown edgings, the feathers of the forehead ba- 

 sally black. Below, white with black streaking laterally, the chin and throat
