Dendroica auduboni (I, 220). in July, 1870, Dr. Cooi)cr fnuiul families of 

 this species fully Hedged, wniulering through the woods, at the suiiunit jiass of the 

 Central Pacific Railroad, 7,000 feet altitude, coutirnnuu' his sui)positiou that they 

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

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

 in fidl plumage, retaining it till August. THeir song is always faint, and similar 

 to that of IJ. astiva. 



Dendroica caerulea (I, 23r>). A nest, containing one egg, of the C'terulean War- 

 bler, was obtained in June, 187.'{, by Frank S. Booth, the son of James liimth, Esq., 

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

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

 It was })laced horizontally on the upper surface of ■: 'ender limb, between two small 

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

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

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

 Itedstart, and (piite small for the bird. It has a diameter of '!}, inches, and is 1] 

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

 nest ehieHy consists of a strong rim firmly woven of stri|)s of fine bai'k, stems of 

 grasses, and fine pine-needles, bound round with flaxen fibres of j)lauts ami wool. 

 Around the base a few bits of hornets' nests, mosses, and lichens av(^ loo.sely 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 apiiearance to that 

 oi D. (vstiva, but is smaller and with a ground-color of a diH'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 suiface with 

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

 reddish-brown surrounds the larger end. 



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

 ber, 1871, by Mr. Allen (Bull. Mns. Comp. Zoiil. Ill, No. 5, p. KIH). 



Dendroica dominica (I, 240). A su[)erb nest of the Yellow-throated AVar- 

 bler was taken by Mr. (Jiles, nc . r Wilmington, N. ('., in t'le spring of 1872. 

 The nest was enclosed in a pendent tuft of Spanish moss {Tillauihia usnenkten), 

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

 roots, nii.xed with much downy material and a few soft feathers, and evcept in its 

 situation, does not diflbr much from other nests of this genus. Otiier nests have 

 since been received from Mr. (;iles ; also a nest' of Puritln americ<i)i<i similarly 

 situated. Mr. Hidgway, 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 War- 

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

 in other similar situations.
