Hah. — North America. Europe. Asia. Australia. In this country throughout the 

 coutiiieut, breeding from Texas to Alaska, and wintering abundantly from the Middle 

 districts southward to Guatemala, Mexico, Cuba, and Jamaica. Replaced in South 

 America by a nearly allied species, A. platalea, Vieillot. 



Lieutenant Warren's Expedition. — No. 5452, Ayoway River. 

 Later Expeditions.— Wtih\-2, Sweetwater; 61111, Green River. 



1 Lave found the Shoveller to be abundaut in season in all parts of 

 the West, and determined its breeding in Northern Dakota, where I 

 ibund young still unable to fly in August, on the Mouse Eiver; and in 

 Montana, along the Milk River and its tributaries, where the bird is 

 common through the summer. The eggs have not, so far as I know, 

 been described from American specimens. They measure on an aver- 

 age 2.10 in length, by 1.50 in breadth; the shape is as usual in the 

 family; the color a uniform dull, pale, greenish-gray, sometimes with a 

 faint bluish tinge. These eggs were taken on the Yukon; the nest com- 

 l)lement was eight. Others from the region last mentioned are entirely 

 similar.
