PASSERINE BIRDS OF NEW YORK 249 



Helminthophila celata (Say). Orange-crowned Warbler 



1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, brownish olive-green. Wings and tail olive-brown, broadly edged with 

 bright olive-green, the median and greater coverts tipped with buff. Below, 

 greenish buff paler and yellower on abdomen and crissum. Lores and auricu- 

 lars grayish buff. Bill and feet pinkish buff, dusky when older. 



3. First Winter Plumage acquired by a partial postju venal 

 moult which involves the body plumage and wing coverts, but 

 not the rest of the wings nor the tail. 



Above, bright olive-green, mostly concealed on the pileum and nape with pale 

 mouse-gray edgings that blend into the green. The crown brownish orange 

 concealed by greenish feather tips. Wing coverts broadly edged with dull 

 olive-green, sometimes the greater coverts with faint whitish tips. Below, 

 pale olive-yellow, grayish on the chin and sides of neck with very indistinct 

 olive-gray streaking. A dusky anteorbital spot. Lores, orbital ring and indis- 

 tinct superciliary stripe mouse-gray. 



4. First Nuptial Plumage acquired b}- a partial prenuptial 

 moult which involves chiefly the anterior part of the head and 

 the chin. A richer, half concealed, orange crown patch is ac- 

 quired ; the lores and adjacent parts become grayer, the anteorbital 

 spot darker. Wear makes birds greener above and slightly 

 yellower below. Young and old become practically indistin- 

 guishable. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult. Differs chiefly from first winter dress in possess- 

 ing a larger, more di.stinct crown patch. The color below is 

 uniform and paler. 



6. Adult Nuptial Plumage acquired by a partial prenuptial 

 moult, as in the young bird. Several March specimens, appa- 

 rently adults, show pin-feathers on the throat and head. 



Fcvialc. — The sexes and the moults are practically alike, al- 

 though the female is usually a little duller. In first winter plu- 

 mage, however, the crown patch is usually wholly lacking, and 

 the first prenuptial moult is more or less suppressed.
