Hab. Eastern United States and Southern Canada to the Plains. Rare 

 or casual east of Central New York and the Alleghanies. Cuba (rare) and 

 Central America in winter. 



Nest, in the outer fork of a branch, 20 to 50 feet from the ground ; com- 

 posed of bark strips, grass and rootlets, and lined with fine grass and fibre ; 

 outside are many pieces of gray moss fastened with spider's silk. 



Eggs, 4 ; creamy-white blotched with brown. 



The Cerulean Warbler is, I think, a regular summer resident 

 in Southern Ontario, but is somewhat local in its distribution. 

 One spring I searched for it carefully near Hamilton without 

 seeing a single individual, while across the bay, four miles off, 

 Mr. Dickson reported it as quite common, and breeding in the 

 woods near the Waterdown station of the Grand Trunk Railway. 

 Its home and haunts are among the upper branches of the trees, 

 and except on a blustering rainy da}^ it is seldom seen among 

 the lower branches. Its song is almost identical with that of 

 the Parula Warbler, but in that species it rises to a slightly 

 higher key at the close, while the Cerulean's ditty is uniform 

 throughout. The colors of the bird are very pleasing when it 

 is seen in a good light, fluttering among the topmost twigs of a 

 beech or maple, the azure-blue and silvery-white seeming like a 

 shred wafted from the drapery of the sky. Dr. Wheaton men- 

 tions the species as abundant in Ohio, but elsewhere it is con- 

 sidered rare. 



261. DENDROICA PENNSYLVANICA (Linn,). «59. 

 Chestnut-sided Warbler. 



Male, in spring, back streaked with black and pale yellow ( sometimes 

 ashy or whitish), whole crown pure yellow, immediately bordered with white, 

 then enclosed in black ; sides ot head and neck and whole under parts pure 

 white, the former with an irregular black crescent before the eye, one horn 

 extending backward over the eye to border the yellow crown and be dissipated 

 on the sides of the nape, the other reaching downward and backward to con- 

 nect with a chain of pure chestnut streaks that run the whole length of the 

 body, the under eyelid and auriculars being left white ; wing-bands generally 

 fused into one large patch, and like the edging of the inner secondaries, much 

 tinged with yellow ; tail spots white as usual ; bill blackish ; feet brown. 

 Female, in spring, quite similar ; colors less pure ; black loral crescent obscure 

 or wanting ; chestnut streaks thinner. Young, above, including the crown.
