THE RED-NECKED GREBE. 559 



PODICEPS, LATHAM. 



Podiceps, LATHAM, Ind. Ornith. (1790), 780. (Type Colymtnts cristatus, L.) 

 Bill long, slender, tapering, and pointed ; nostrils situated in a groove, small, 

 linear, and pervious; wings short and narrow, second primary a little the longest, 

 emarginate near the ends ; tail a tuft of loose feathers ; tarsi short, much compressed, 

 the edges covered with small scutellse, and the sides with broad transverse sciitellae; 

 toes long, the outer longest, flattened, with the sides lobed, the most on the inner 

 side, and at the base united by webs ; hind toe short and broadly lobed, claws small, 

 depressed, and obtuse. 



These birds mostly frequent the fresh-water rivers and interior lakes ; but they are 

 also found near the seacoast. They are very expert swimmers, but make progress 

 with great difficulty on land ; their flight is rapid and direct. In the breeding season, 

 the head is ornamented with ruffs and elongated tufts, which disappear when they 

 assume their winter garb.

The Red-necked Grebe is common on our coast in winter, 

 where it is commonly called " The Diver," from its habit of 

 diving at the flash of a gun. It feeds, like all other birds 

 of this family, on small fishes and marine animals, which it 

 obtains by diving ; and such is its expertness and powers 

 of endurance in this respect, that I have known it to remain 

 certainly a minute beneath the surface, if not longer. It is
