614 MICHIGAN BIRD LIFE. 
contained three young birds with the feathers just beginning to appear 
on the wings.” 
Dr. Dunham found it in Kalkaska county in the nesting season and 
states that on June 22, 1899 he took a male near East Lake, Kalkaska 
county and saw about a dozen more in the evergreens. It is a not un- 
common summer resident in Emmet county, where Widmann found it 
feeding grown young in the tree tops in July 1901. §. E. White found it 
a rather common summer resident among the evergreens on Mackinac 
Island, in 1890 and 1891, and Dr. Wolcott found it at Charlevoix in summer 
and was confident that it nested there. Mr. O. B. Warren thought it 
might possibly breed in Marquette county in 1898, and Mr. T. B. Wyman 
in 1905 was positive that it bred near Negaunee in the same county. It 
was found at various times in the late summer in the Porcupine Mountains, 
Ontonagon county, by the University of Michigan expedition, and a pair 
with two young were seen in the tops of the birches July 14, and one adult 
female was taken while feeding young not able to fly. These facts show 
that the Blackburnian Warbler certainly nests rather commonly throughout 
northern Michigan and occasionally in favorable localities throughout the 
southern half of the state. 
So far as we are aware there is nothing peculiar about its food habits, 
but it consumes immense numbers of insects and probably is just as valuable 
to the agriculturist as many of its congeners. 
TECHNICAL DESCRIPTION. 
Adult male: Upper parts, from bill to tail, mainly clear black, middle of crown with 
a spot of pale orange; middle of back streaked with pure white; chin, throat, sides of neck, 
and line from bill over eye, rich orange; rest of under parts pale yellow, bleaching to white 
on the under tail-coverts, the sides and flanks streaked with black; lores, cheeks, and one 
or two spots on side of neck, black; two white wing-bars, often connected; most of the 
tail-feathers with white spots, the three outer pairs mainly white on their inner webs, 
merely black-tipped. Female similar, but smaller, the orange replaced with pale yellow 
or yellowish white, the black replaced mostly with brownish-gray; upper parts streaked

280. Sycamore Warbler. Dendroica dominica albilora Ridgw. (663a) 
Synonyms: White-crowned Yellow-throated Warbler, White-browed Warbler, White- 
cheeked Warbler.—Sylvia and Sylvicola pensilis, Aud.—Dendroica superciliosa, Baird 
(part).—D. d. albilora of most recent authors. 
The rich yellow chin and throat, bordered by clear black at the sides 
and fading into white on breast and belly, is nearly distinctive. Add 
to this the white line over the eye, the black forehead, two white wing-bars, 
and the white-blotched outer tail-feathers, and there can be no mistake. 
Only the expert can separate it from the Yellow-throated Warbler, 
Dendroica dominica, but this does not occur in Michigan (see Appendix). 
Distribution.—Mississippi Valley, west to the Plains, north to Lake 
Erie and southern Michigan, and east to Western North Carolina; in 
winter south to southern Mexico, Honduras, Guatemala and Nicaragua. 
This beautiful but little known warbler appears to be a somewhat regular 
visitor to certain regions in the southern and southeastern parts of the 
state. It has been reported from the Raisin River valley in Monroe
