 2 Species. 



Very dexterous diving birds of lakes and rivers, as well 

 as of salt water, variously crested in the breeding-season; 

 their bodies are held upright by the posterior position of the 

 legs ; they are practically tailless, and, though smaller, bear 

 a close resemblance to the Loons.
