the Indigo. Mr. Brewster describes it tints : fwsrc-fii'scc-hi'scc- 

 sec\ the last two rising and terminating abruptly. I find no 

 mention of a .song period in fall. The song has a certain ven- 

 triloquial quality. 



The birds frequent the tops of trees bordering streams, 

 moving about rather leisurely for warblers. 



This species is confined to the southern United vStates, 

 north to southern Maryland and Virginia, rarely to southern 

 New England. The sub-species 



Sycamore "Warbler. Doniroira domhiica albilora. <)()8a. 



Is the form which inhabits the Mis.sissippi Valley from western 

 North Carolina to the Plains, north to .southern Michigan. 



The described songs seem to be practically identical with 

 those of the species. Prof. A. W. Butler gives the fullest de- 

 scription : tiuit, che-e, dic-t\ chc-e, chc-c\ che-a, the first abrupt 

 with ri,sing inflection, the next four following after a pause, 

 all on the same pitch, the last ri.sing sharply. While the syl- 

 lables are different the description is almost exactly as above. 



As the name indicates, this Warbler is mo.st at home among 

 the upper branches of sycamore trees which fringe the streams. 

 His untiring activity makes .study tantalizing. 



Kirtland's Warbler. Dcudroica kirtlaiidl. ()70. 



The song of this rare Warbler .shows a marked tendency 

 toward the Maryland Yellow-throat type, with a full oriole-like 

 quality, " in marked contrast to the high notes of many war- 

 blers." It also resembles the .song of the Yellow-throated. 

 Warbler. There are no syllable descriptions. 



The rarity of this Warbler makes his geographical distribu- 

 tion .somewhat uncertain. But he seems to be one of the 

 warblers of the eastern part of North America, west at least 

 into Illinois and Wisconsin, and east to Wa.shington, D. C. 

 He probably breeds north of the ITnited States 



Kentucky Warbler. Dcudroica formosa. (i77. 



The song of this species is probably more like the whistle 

 of the Carolina Wren than any other Warbler. Mr. Burns has
