R28 BIRDS OF OHIO. 
17. (21.) HELMINTHOPILA LEUCOBRONCHIALIS (Brewst.). 
Brewster Warbler. 
Synonym: Helminthophaga leucobronchialis. 
Jones, Wilson Bulletin, No. 42, June 15, 1903, 68. 
On May 23, 1902, while out with my class for 
early morning study, we discovered a singing male 
of this interesting form. The first part of the song 
was clearly Blue-wing. in all particulars, while the 
last was just as clearly Golden-wing. The students 
noticed the oddity of the song without having their atten- 
tion especially called to it. We studied the bird in all 
lights and positions for half an hour, many times within 
fifty feet, with a pair of stereo-binoculars, clearly making 
out the white underparts, faintly tinted with yellow on the 
breast and a slight darkening of the chin feathers, the yel- 
low crown and great yellow wing patch. On the 28th we 
again found the bird in the same situation, on the border 
of an open woods, and gave it even more attention than be- 
fore. It was in full song, and seemed less wary than be- 
fore. A week later it was gone. The evidence of nesting 
seemed so strong that I was unwilling to collect* the bird, 
hoping to secure a breeding record and be able to study the 
hybrid family. The bird was probably not strictly typical 
leucobronchialis, but came near to it, as indicated by both 
song and plumage. 
During the spring of 1903 two almost typical specimens 
have been secured and at least one other seems to be tarry- 
ing to nest in a woods half a mile west of Oberlin. I am 
hoping to add some direct testimony to the life history of 
this interesting variation. 
18. (22.) HELMINTHOPILA CINCINNATIENSIS (Langd.).

Cincinnati Warbler. 
Synonym.. Helminthophaga cincinnatiensis.
