eastern Massachusetts, June 9 (Maynard), and we have the same 
authority for its departure from Upton, Maine, June 5 ; Central Ver- 
mont, “only a few days in the first of June” (N. A. Birds), while 
Audubon gives it as arriving in Labrador, June 1 to 10. As to the 
data of its breeding- we have the records of nests with eggs at Fort 
Yukon, June 1 and 9, and at Great Slave Lake the same month. In 
a paper read before the Linnsean Society of New York, an abstract 
only of which has appeared in print,* Mr. R. F. Pearsall said of this 
species that, on the island of Grand Menan, “ W e found them ( June 12, 
1878) with full complements of four, frequently five eggs, incubation 
having just commenced,” and also, that at the Rangeley Lakes, Maine, 
a nest with five eggs was taken June 19, 1879.'}" 
The facts above stated form a chain of evidence which strongly 
supports the probability that the individuals of the Black-poll War- 
bler found in southern New York after the middle of June were sum- 
mer residents of the mountain summit they inhabited. 
Deiulrorca Blackburn i;e (Gm.) Baird. Blackburnian Warbler. 
Though I did not myself meet with this species, Mr. Burroughs 
writes me that it breeds in Delaware County, just beyond Pine Hill. 
The same author, in a delightful account of the bird life of a Catskill 
forest, in “Wake Robin,” page 49, alludes to the capture of one of 
these beautiful warblers. 
Mr. Pearsall observed an individual of this species in the Big 
Indian Valley on May 30. 
Demlrceca virens (Gm.) Baird. Black-throated Green Warbler. 
Not uncommon; preferably inhabiting hemlock woods, and scattered 
sparingly through the deciduous forests. 
Siurus auricapillus (L.) Sw. Golden-crowned Thrush. 
Not uncommon in mountain woods; often its song was heard far 
in the forest. 
Siurus motacilla (Vieill) Coues. Large-billed Water Thrush. 
Had we not been prepared by Dr. A. K. Fisher’s recent announce- 
ments X of the presence of this species in its breeding season at 
Lake George for other records of its occurrence north of its known

f Since the above was penned Mr. Brewster has described a nest and set of three eggs of the 
Black-poll Warbler which was taken by Mr. M. A. B’razar at the Magdalen Islands, June 23, 1882. 
The eggs were fresh. — See Bull. Nutt. Ornith. Club, VII, 4, 2 53 — 2 S 4 , October, 1882.
