560 ORNITHOLOGY AND OOLOGY. 



shy, and difficult of approach ; and, when apprehending 

 danger, it immerses its body, and swims with notliing but 

 its head above the surface. This trick I liave noticed in 

 other allied species ; and it is, I think, common in all birds 

 of this class. It breeds in the most northern portions of 

 the continent, where it forms the same kind of nest " as 

 that of the Crested Grebe, and lays three or four eggs." 

 Audubon describes an egg in his possession as being two 

 inches in length by one and a quarter inch in breadth, and 

 of a uniform pale greenish- white.

This is not uncommon as a summer resident in northern 

 New England ; and, according to Mr. George A. Boardman, 

 it breeds about the lakes in the neighborhood of Calais, 

 Me. The nest is placed in a retired spot, in a swamp or 

 marsh, near the water; and is constructed, according to Dr. 

 Richardson, of " a large quantity of grass, placed among 

 the reeds and carices." The eggs are generally four in
