578 APPENDIX. 



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 N2EVIUS. Varied Thrush. But one instance on record of 

 its capture in New England ; at Ipswich, Mass., December, 1864. Acci- 

 dental; from the West. 



SAXICOLA (EHANTHE. Stone Chat Not as yet, I believe, actually ob- 

 tained within the limits of New England ; but as it has, accordirig 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 C.ERULEA. Blue-Gray Gnatcatcher. An accidental sum- 

 mer visitor to southern portions of New England. No recent instance 

 of its occurrence on record. 



LOPHOPHANES BICOLOE. Crested Titmouse. An accidental species, 

 same as the preceding. 



TROGLODYTES AMERICANUS. Wood Wren. I have never met with thia 

 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 : 



" It was planed 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.
