Dendroica auduboni (I, 229). In July, 1870, Dr. Cooper found families of 

 this species fully lletlgcd, wandering through the woods, at the summit pass of the 

 Central Pacific Railroad, 7,000 feet altitvide, confirming his supposition that they 

 breed in the high Sierra Nevada. There they are very numerous in summer, 

 following the retreating snow to this elevation about May 1, when the males are 

 in full plumage, retaining it till August. Their song is always faint, and similar 

 to that of D. cestiva. 



Dendroica caerulea (1, 235). A nest, containing one egg, of the Cserulean War- 

 bler, was obtained in June, 1873, by Frank S. Booth, the son of James Booth, Esq., 

 the well-known taxidermist of Drummondville, Ontario, near Niagara Falls. The 

 nest was built in a large oak-tree at the height of fifty feet or more from the ground. 

 It was placed horizontally on the vipper surface of a slender limb, between two small 

 twigs, and the branch on which it was thus saddled was only an inch and a half in 

 thickness. Being nine feet from the trunk of the tree, it was secured with great 

 difficulty. The nest is a rather slender fabric, somewhat similar to the nest of the 

 Redstart, and quite small for the bird. It has a diameter of 2| inches, and is 1^ 

 inches in depth. Its cavity is 2 inches wide at the rim, and 1 inch in depth. The 

 nest chiefly consists of a strong rim firmly woven of strips of fine bark, stems of 

 grasses, and fine pine-needles, bound round with flaxen fibres of plants and wool. 

 Around the base a few bits of hornets' nests, mosses, and lichens are loosely fastened. 

 The nest within is furnished with fine stems and needles, and the flooring is very 

 thin and slight. The egg is somewhat similar in its general appearance to that 

 of B. cestiva, but is smaller and with a ground-color of a diff"erent shade of green- 

 ish-white. It is oblong-oval in shape, and measures .70 of an inch in length by 

 .50 in breadth. It is thinly marked over the greater portion of its surface with 

 minute dottings of reddish-brown. A ring of confluent blotches of purple and 

 reddish-brown siuTounds the larger end. 



Dendroica blackburniae (I, 237). Obtained at Ogden, Utah, in Septem- 

 ber, 1871, by Mr. Allen (Bull. Mus. Comp. Zool. Ill, No. 5, p. 166). 



Dendroica dominica (I, 240). A superb nest of the Yellow-throated War- 

 bler was taken by Mr. Giles, near Wilmington, N. C, in the spring of 1872. 

 The nest was enclosed in a pendent tuft of Spanish moss {Tillandsia usneoides), 

 and completely hidden within it. Its form is cup-shaped, and it is made of fine 

 roots, mixed with much downy material and a few soft feathers, and, except in its 

 situation, does not diff"er much from other nests of this genus. Other nests have 

 since been received from Mr. Giles ; also a nest of Panda americana similarly 

 situated. Mr. Ridgway, from an examination of the nests, infers that this situation 

 is not constant, but that in other localities where the moss is not found this "\\ ar- 

 bler may build in thick tufts of leaves near the extremity of drooping branches, or 

 in other similar situations.
