560 ORNITHOLOGY AND OOLOGY. 
shy, and difficult of approach; and, when apprehending 
danger, it immerses its body, and swims with nothing but 
its head above the surface. This trick I have noticed in 
other allied species; and it is, 1 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
