H. PEREGRINA : TENNESSEE WARBLER. 121 



only a migrant as far north as Massachusetts. Enter- 

 ing Maine, however, the face of the record changes 

 directly. Prof. Verrill reports the bird from the head- 

 waters of the Penobscot in June, where it was doubt- 

 less breeding ; it was found by Mr. Boardman in the 

 vicinity of Calais, in the breeding season ; and Mr. 

 Maynard reports it as very common at Umbagog in 

 the same period of its life, adding the following note : 

 " This beautiful little species breeds at Upton ; two or 

 three females were taken about June 8th, which showed 

 every evidence of incubating, yet we were unable to 

 discover the nest, though diligent search was made 

 for it in localities where it must have been built. The 

 nest is probably placed on the ground, after the man- 

 ner of all the genus. The bird is found in all wooded 

 localities in the region north of the neighboring moun- 

 tain range, which is without doubt its southern limit 

 during the breeding season." From the Canadian, 

 then, the bird breeds northward through the Hudso- 

 nian, Fauna, and even to Arctic America ; but I 

 am aware that an authentic nest has been found in 

 New England, and even so far south as Springfield, 

 Mass., where it was secured by Professor Horsford, 

 the parent having been also taken, confirming the 

 identification. It is described by Dr. Brewer as built 

 in a low clump of bushes, just above the ground, and 

 constructed of fine vegetable fibres, grasses, mosses 

 and the like, and lined with hair ; it was 2| inches 

 in diameter, by 2 in depth, with a cavity 2Xif. 

 The eggs, measuring 0.60x0.50, were pearly white, 

 wreathed about the larger end with brown and pur- 

 plish markings.
