NORTH AMERICAN BIRDS EGGS. 



305 



68 I a. Western Yellow-throat. G. t. occidentals. 



Range. This variety, which is said to be brighter yellow below, is ascribed to 

 the arid regions of western United States; not on the Pacific coast. 



68 I b Florida Yellow-throat. G. t. ignota. 

 Range. South Atlantic and Gulf coast to Texas. 



68 I c. Pacific Yellow-throat. G. t. arizela. 

 Range. Pacific coast from British Columbia southward. 



68 Id. Northern Yellow-throat. G. t. brachidactyla. 



Range. Eastern United States from New Jersey to Newfoundland and west to 

 the Mississippi Valley; winters south to the Bahamas and Mexico. 



This is the common Yellow-throat which breeds so abundantly in New 

 England and in the Mississippi Valley whose nests so many have tried to 

 find without success, for the birds are very knowing and glide off upon the 

 approach of anyone and are very careful not to betray their treasures; the 

 birds, the nests, and the eggs are like the ones described as trichas. 



68 I e. Salt Marsh Yellow-throat. G. t. sinuosa. 

 Range. Salt marshes of San Francisco Bay. 



682. Belding Yellow-throat. Geothlypis beldingi. 

 Range. Lower California. 



This peculiar species is like the common Yellow-throat but has the black 

 mask bordered by yellow instead of white, and the black on the forehead extends 

 diagonally across the head from in front of one eye to the rear of the other. 

 Their habits are like those of the other Yellow-throats and the nests are similar 

 to those of the latter, which are frequently placed in cane over the water. Nests 

 found by Mr. Walter E. Bryant were situated in clumps of "cat-tails" between 

 two and three feet above the water; the nests were made of dry strips of these 

 leaves, lined with fibres; the eggs were like those of the common Yellow-throats 

 but larger; size .75 x .56. 



682.1. Rio Grande Yellow-throat. Geothlypis poliocephala. 



Range. Mexico north to the Lower Rio Grange Valley in Texas. 



This Yellow-throat has the crown and ear coverts gray, only the lores and 

 forehead being black. The nests and eggs of these birds, which are fairly com- 

 mon about Brownsville, Texas, do not differ from those of the other Yellow- 

 throats. 



683. Yellow-breasted Chat. Icteriavirens. 



Eastern United States, breeding from the Gulf coast north to southern New 

 England and Minnesota. 



This strange but handsome species is very common in ^GS^^^ 



underbrush and thickets in the south; they are usually shy 

 and endeavor, with success, to keep out of sight, but their 

 strange song and calls, consisting of various whistles and 

 squawks mingled together, are often heard. Their nests 

 are built in bushes or briars at low elevations, being made 

 of grass, strips of bark and leaves, lined with finer grass; [White.] 



their eggs are white, sharply specked and spotted with vari- 

 ous shades of brown and lavender; size .90 x .70. 



683a. Long-tailed Chat. Icteria vir ens longicauda. 



Range. United States west of the Plains, breeding from Mexico to British 

 Columbia. 



This bird is said to be grayer and to have a slightly longer tail than the last, 

 i Its nesting habits and eggs are precisely the same.
