62 AMERICAN ORNITHOLOGY. 



clear and with a faint suggestion of the Indigo-Bunting melody, it 

 being an unusual song for a Warbler. Their habits are quite similar to 

 those of the Black and White Warbler, being in fact, as much like those 

 of a creeper as a Warbler. They are persistent gleaners and often 

 give voice to their little song as they clamber about among the branch- 

 es. It will be noticed that their bills are longer and more curved than 

 those of the other Warbler. 



GRACE WARBLER, 



A. O. U. No. 664. (Dendroica gracicp). 



RANGE. 



Western United States breeding in the mountains of Arizona and 

 New Mexico, and wintering in the western part of Mexico. 

 DESCRIPTION AND HABITS. 



This species averages about a quarter of an inch less in length than 

 the last, to which it bears some resemblance although it has a typical 

 warbler bill; the entire supercialiary line is yellow, the sides of the 



head are gray and the back is marked with black streaks or arrow 

 heads. These birds are quite abundant in pine woods at high elevations 

 in southern Arizona. Their nests are placed high up in coniferous 

 trees usually in a bunch of needles at the end of a limb. They are 

 therefore quite difficult to find and their eggs are scarce. The nests 

 are made of grasses, bark, needles, etc., and are lined with hair and 

 feathers; the eggs are white with reddish brown specks, chiefly on the 

 larger end. 



BLACK^THROATED GRAY WARBLER, 



A. O U. No. 665. ( l>eiidroi<'a nlgrescens.) 



RANGE. 

 Western United States, breeding from southern Arizona and south- 

 ern California north to British Columbia and east to the middle of Col- 

 orado. They winter in the southern part of Mexico. 



HABITS. 

 Black-throated Gray Warblers are easily identified by their black, 

 white and gray colors and the small yellow spot on the lores. These 

 birds return to our country from their winter quarters about the first
