17. Querquedula discors. Blue-winged Teal. — Not so common as 

 N. carolinensis, but seen quite often.

 than in summer. Usually found in company with the Mallard. 



19. Dafila acuta. Pintail. — Not nearly as numerous as the Mallard, 

 but quite often found nesting. 



20. Marila americana. Redhead. — Very rare; seen only during 

 spring and fall. 



21. Marila vallisneria. Canvas-back. — Very rare; about as common

 during the spring and fall and met with occasionally in summer. A nest 

 found near here with ten eggs. 



25. Charitonetta albeola. Buffle-head. — Almost as common as the 

 Mallard; nearly every small pond has its pair, and some of them two pairs, 

 of this beautiful little duck. When two or more pairs occupy a single 

 pond, the males are usually very pugnacious, often quarreling and trying 

 to drive each other off the pond for hours at a time.

 was brought in by a taxidermist.

 once in May and once in July.

 diate vicinity, but nests in large colonies some sixty miles to the southeast.

 stopping at least for part of the summer along the larger lakes. One nest 

 was located, which was afterwards abandoned. 



36. Grus canadensis. Little Brown Crane. — Seen occasionally,
