614 MICHIGAN BIRD LIFE. 



contained three young ])ii'(ls with the feathei's just beginning to appear 

 on the wings. " 



Dr. Dunham found it in Kalkaslca county in the nesting season and 

 states that on June 22, 1899 he took a male near East Lake, Kallvaska 

 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. S. 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. 0. 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 Blacklnirnian 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 ]'»r()l)al)ly is just as valuable 

 to the agriculturist as many of its congeners.

280. Sycamore Warbler. Dendroica dominica albilora Ri(J(/ir. (663a) 



Synonyms: White-crowned Yellow-thi-oated Warbler, White-browed Warbler, White- 

 cheeked Warbler. — Sylvia and Syhicdhi ]>L'nsilis, Aud. — Dendroica superciliosa, Baird 

 (part). — D. d. albilora of most recent autliors. 



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-lxars, 

 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 repoitod fi'om the Raisin River valley in Moni'oe
