than the eggs of the common black duck. In its 

 habit the bird closely resembles Anas obscura. 

 The flesh is excellent. 



Mr. N. B. Moore, in " Baird, Brewer, and Ridge- 

 way," gives an interesting description of this bird : 

 " In August and September small flocks leave the 

 fresh ponds and fly across the bay to sand-bars on 

 the inner sides of the keys, where they spend the 

 night in pools or coves, returning at sunrise. 

 Those shot at this time are all males. In the 

 late winter and early spring mated birds resort to 

 the same places." Mr. Moore suggests as a 

 reason for this species not being more common 

 in the districts it frequents, the sweeping fires 

 which destroy the dry grass.
