BIRDS OF KANSAS., 565 



the tallest trees, out of gnnshot, and often, practically, out of 

 sight, although his presence is betrayed by his loud, very un- 

 Warbler-like song. The song of this species is so much like that 

 of the Indigo Bird, that it requires a practiced ear to distinguish 

 them; the tone is remarkably similar, but there is a difference 

 in the modulation, which, after one becomes thoroughly ac- 

 quainted with it, renders it distinguishable. In its motions, this 

 warbler partakes much of the character of a creeper, often 

 ascending or descending trunks of trees, or following their 

 branches, much in the manner of a Mniotilta. The first speci- 

 men which the writer ever saw was creeping about the eaves 

 and cornice of a frame dwelling house, in the center of the town 

 of Mt. Carmel. Very often, however, it could not be distin- 

 guished from other Warblers, so far as its actions were con-

In my "Revised Catalogue of the Birds of Kansas," I de- 

 scribed what I then supposed to be the nest and eggs of these 

 birds, I am now satisfied that the authority is not reliable, upon 

 which the entry was based, I have met with the birds at Neosho 

 Falls, Kansas, on several occasions, during the summer months, 

 and once as early as the last of April; always in or about the 

 large sycamore trees, along the banks of the Neosho Kiver; but 

 have never been so fortunate as to find them nesting anywhere, 

 neither can I find any authentic description of their nests and 

 eggs. They undoubtedly nest in the treetops, like the eastern 

 bird, D. dominica.
