NORTH AMERICAN BIRDS EGGS. 71 



134. Florida Duck. Anas fulvigula. 



Range. Florida and the Gulf coast of the Mississippi. 



This is a similar, lighter colored, locally distributed race of the foregoing.

 the absence of marking on the chin. The habits are the same, and the eggs, 

 which are deposited in April, are similar to those of the Black Duck, but 

 smaller. Size 2.15 x 1.60. 



I34a. Mottled Duck. Anas fulvigula maculosa. 



Range. Gulf coast of Texas and up the Mississippi Valley to Kansas.

 ten eggs are greenish buff in color. Size 2.15 x 1.55. 



135. Ga'dwall. Chaulelasmus streperus. 



Range. Northern Hemisphere, 

 breeding in America, chiefly in the 

 United States and north to Manitoba,

 males of these birds may be identified 

 by the white speculum and the chest-

 the ground among the reeds of marshes
