northern sections. Is generally found in thick undergrowth in swampy 
localities. It is said to have a more musical note than other species of 
this genus; and, according to William Brewster, of Cambridge, its song 
somewhat resembles that of the Wood Pewee, but it is not so prolonged, 
and much more subdued. 
TURDUS NEVIUS. Varied Thrush.— But one instance on record of 
its capture in New England; at Ipswich, Mass., December, 1864. Acci- 
dental; from the West. 
SAXICOLA @NANTHE. Stone Chat.— Not as yet, I believe, actually ob- 
tained within the limits of New England; but as it has, according to 
Coues, been found in Nova Scotia, Labrador, and on Long Island, it 
may occur. ‘The species is a straggler from Europe, and entirely acci- 
dental. 
POLIOPTILA CEHRULEA. Blue-Gray Gnatcatcher.— An accidental sum- 
mer visitor to southern portions of New England. No recent instance 
of its occurrence on record. 
LOPHOPHANES BICOLOR. Crested Titmouse.— An accidental species, 
same as the preceding. 
TROGLODYTES AMERICANUS. Wood Wren.—I have never met with this 
species ; but was induced to include it in my list of Massachusetts birds, 
published in 1864, because several collectors and others had informed me 
that it was occasionally found here. Thompson and others include it in 
their catalogues, and its egg is even said to have been found by Dr. 
Brewer. I doubt that the species is well established, and have no knowl- 
edge of an authentic specimen in any collection. 
GEOTHLYPIS PHILADELPHIA. Mourning Warbler.— Chiefly a rare spring 
and autumn migrant; but it breeds in northern and elevated portions of 
New England. A nest said to belong to this species, found by Mr. John 
Burroughs about the head-waters of Delaware River, in the Catskill 
Mountains, N.Y., is thus described by him in the ‘‘ Atlantic” for June, 
1869 : — 
‘«Tt was placed in a bunch of ferns, and about six inches from the 
ground. It was quite a massive nest, composed entirely of the stalks 
and leaves of dried grass, with an inner lining of fine, dark brown roots. 
The eggs, three in number, were of light flesh-color, uniformly specked 
with fine brown specks. The cavity of the nest was so deep that the 
back of the sitting bird sank below the edge.” 
According to this writer, the song of this bird resembles that of the 
Maryland Yellow Throat. Like that species, it gives a preference to 
damp places.
