, LIST AND DESCRIPTION 125 



646. ORANGE-CROWNED WARBLER (Vermivora celata celata.) 



Above, olive green with concealed orange crown patch; 

 below, dusky yellow. It is seen only in migration and might 

 asily be mistaken for the female Summer Warbler. 



647. TENNESSEE WARBLER (Vermivora peregrina.) 



Rare in migration over the State. Above, olive green; 

 below, whitish. Head light slate with white line over the eyes. 

 Plumage much like that of the Red-eyed Vireo but easily iden- 

 tified by its smaller size and bill. 



652. YELLOW WARBLER (Dendroica aestiva aestiva.) 



A common resident. Called also Summer Warbler. This 

 is the only South Dakota bird that has the appearance of being 

 wholly yellow. The yellow of the male is much less olivaceous 

 than that of the female, while his breast is obscurely striped with 

 broad bands of reddish brown. By many this bird is confused 

 with the American Godfinch. Although a bird of the under- 

 brush, in South Dakota, where there is so little underbrush, it 

 nests freely in orchards, and even in the bushes of our door yards. 

 It is the best known bird that discerns the danger of the Cow- 

 bird's egg, and when this egg is found in her nest, the little 

 mother will often bury it, together with her own, by laying a 

 new bottom and sometimes adding a second story to her nest. 



655. MYRTLE WARBLER (Dendroica coronata.) 



An abundant migrant. Bluish gray, heavily streaked and 

 blotched with black and white; easily recognized by the yellow 

 patches on crown, rump and sides. It is commonly called the 

 Myrtle Bird. 



656. AUDUBON'S WARBLER .Dendroica auduboni auduboni.) 



"Seen frequently in the Black Hills ; probably nests. Com- 

 mon spring migrant along the White River" (Sweet). It is easy 

 to mistake this beautiful bird for the more common Myrtle 

 Warbler. Its yellow throat patch, however, distinguishes it; 

 and, unlike the two bars of the Myrtle Bird, the white of its 

 'wings is a solid patch.
