Nest, of reeds, grasses, etc., rather closely woven, in grassy marshes or 

 vegetation floating in a slough. Eggs, two to three, grayish olive-brown, 

 rarely whitish, heavily spotte"d and blotched with chocolate markings, fre- 

 quently confluent about the larger end, 1'35 x -98.

" It seems not to subsist on fish at all, but chiefly on dragon flies 

 and various aquatic insects. It finds both its home and its food in 

 the marshes usually, but its powers of flight are so great that it may 

 also be seen far out on the dry open plains, scouring the country for 

 food at a distance of miles from its nesting ground. . . . 



" The bird may frequently be seen dashing about in a zigzag man- 

 ner so swiftly, the eye can offer no 'explanation of its motive until, on 

 the resumption of its ordinary flight, a large dragon fly is seen hang- 

 ing from its bill. . . ." (Thompson).
