BLACKBURNIAN WARBLER 

 DENDROICA BLACKBURNLE (Gmel.) Plate III 



Distinguishing Characters. — The adult <? in Spring has the center of the 

 crown, line over eye, sides of neck and breast flaming orange; in the adult 6* 

 in Fall and adult 9 in Spring these parts are dull orange or yellowish orange, 

 in young birds these areas are still duller. Birds in the last-named plumage 

 may cause some difficulty in identifying but the marks named, in connection 

 with a brownish, obscurely streaked back, and generally white outer web of the 

 basal half of the outer tail-feather, should be diagnostic. Length (skin), 4.60; 

 wing, 2.65; tail, 1.95; bill, .40. 



Adult c?, Spring. — Center of crown, streak below eye, line over eye to a 

 patch on the side of the neck orange, ear-coverts and lores black; upperparts 

 black, the back streaked with white which, in some specimens, is tinged with 

 orange; tail black, edged with grayish, the inner web of the two to four outer 

 feathers largely white, the outer web white at the base, the next feather usually 

 with a white spot near the tip of the inner web; wings black edged with sage; 

 the median coverts white, outer greater coverts tipped with white, the inner 

 greater coverts with white margin or wholly white, forming a large white 

 patch in the wing; throat and breast flaming orange usually deeper than that 

 of crown, this color generally suffusing the whitish abdomen, sides streaked 

 with black. 



Adult <$, Fall. — Similar to adult c? in Spring but the orange much paler 

 and veiled with buffy tips; the black markings widely bordered with brownish; 

 wings with two white bars, not forming a patch. 



Young c?, Fall. — Similar to adult c? in Fall but orange markings less pro- 

 nounced and still paler, becoming dull yellow; black markings less pronounced 

 and mixed widely with grayish olive or olive-brown.
