HABITS. 



The only time that I ever met with the beautiful, little Blue Warbler was at Williams- 

 port, Pennsylvania, about the tenth of May. There was a large migration of Warblers 

 passing at the time, and this species was among them, but was rather rare. In general 

 habits, this bird resembled other Warblers, and I was not fortunate enough to hear the 

 song. 



DENDRCECA BLACKBURNI^J 



Blackbumian Warbler. 



Dendrceca Blackhurnut BD., Birds N. A.; 1858, 274. 



Si-. On. Eorm, slender. Size, large. COLOR. Adult male. Above, sides of head and neck, and streaks on sides, 

 black. Outer edge of secondaries, large patch on wings and one on inner webs of three outer tail feathers, white. Sjxit 

 on crown, superciliary stripe, patch on neck, throat, and upper breast, bright orange, becoming creamy on remainder of 

 lower surface. Iris, bill, and feet, brown. Female, himilar but duller, and the white patch on wings in divided into two 

 bands. Young, like adulfc female but very much paler, the yellow on the breast and streaking* above in young females 

 being nearly obsolete. 



Observations. Known by the dark colors above, orange throat and supercil iary line, which are discernible in all stag-

 wing, 2-65; tail, 1'85; bill, '75; tarsus, -38. 



HABITS. 



I .shot a female Blackburnian Warbler at Williainsport, Pennsylvania, that exhibited 

 unmistakable evidences of having recently deposited her eggs, and afterward saw several 

 other specimens there, so I have no doubt but what these. Warblers breed in that section, 

 though as a rule, they nest much further north, in the evergreen woods of Maine, where they 

 are very abundant. The Blackburnians are rare in Eastern Massachusetts during migra- 

 tions, but are remarkably abundant in the valley of the Susquehanna at this time, insomuch 

 so, that I have counted upward of twenty in sight at once. I have never met with the nest 

 and eggs of this species, but am confident that it breeds in high evergreen trees.
