bars washed with yellow; in other words, about intermediate between typi- 
cal leucobronchialis and typical pinus. 
This hybrid between pinus and chrysoptera or color phase of pinus , 
has been found in Louisiana, from Virginia northward to Connecticut, 
and as far west as Michigan, Its breeding range apparently coincides 
with the northern portion of that of pinus . Upward of one hundred 
and fifty specimens, representing typical leucobronchialis and various 
phases of its intergradation with pinus are known, and in the Connect- 
icut River Valley the bird is stated to be more frequent than chrysoptera. 
In general habits it resembles both pinus and chrysoptera. Some in- 
dividuals sing like the former, some like the latter, while others 
have notes of their own. The significant facts in the bird’s interest- 
ing and puzzling history are given in the Warblers of North America, 
pp. 72-77, and by Faxon in the Memoirs Mus. Comp. Zool., 1910, XL, 
pp. 57-78. 
Vermivora lawrencei {Herrick). Lawrence’s Warbler. Ad. <?. — 
Forehead and forepart of the crown yellow, rest of the upperparts bright 
olive-green; wing-bars white; tail bluish gray, the three to four outer feathers 
marked with white; a black patch on the cheek divided by a yellow line 
from the black patch on the throat and upper breast ; lower breast and belly 
yellow, under tail-coverts white. Ad. 9 . — Forehead dingy yellow, rest of 
the upperparts bright olive-green; wing-bars white, tinged with yellow; tail 
as in the d\ black patches of the <? replaced by dusky olive-green. 
Remarks. — This bird combines the characters of pinus and chrysoptera; 
it has the black cheek-patches and breast-patch of the latter, but in other 
respects resembles the former, and is doubtless a hybrid between the two. 
Its history and a discussion of its relationships will be found under the refer- 
ences given above. It is a much rarer bird than Brewster’s Warbler, and 
less than a score of specimens have been recorded. 
The bird resembles Brewster’s Warbler in haunts and habits, and, 
like that puzzling bird, it sings like both pinus and chrysoptera. 
642. Vermivora chrysoptera {Linn.). Golden-winged Warbler. 
(Fig. 117.) Ad. cf. — Crown bright yellow; rest of the upperparts bluish gray,

rated from another on the throat by a white stripe; a white line over the eye; 
wings and tail bluish gray; tips of middle wing-coverts and outer webs of 
greater ones bright yellow, forming a large yellow patch on the wing; outer 
three tail-feathers with large white patches on their inner webs at the tip, 
fourth feather with a smaller patch; lower breast and belly white; sides 
grayish. . Ad. $ . — Similar, but the crown and upperparts duller, the patch
