surface, from which they also pick up any sort of garbage suited to 

 their appetite ; sometimes they pursue and attack the small terns and 

 gulls, to force them to disgorge the small fish that they have captured. 

 They are able to capture live fish with considerable dexterity, but can- 

 not feed on the wing; occasionally these birds alight on the backs of 

 cattle, to search there for the larvae which frequently harbor in their 

 skin. During the winter and spring, the Fish Crows are very fond of 

 feeding on many kinds of berries. As spring advances, and the early 

 fruits ripen the Fish Crows become fond of the mulberry, and select 

 the choicest of the ripe figs, more especially when they are feeding 

 their young. A dozen are often seen at a time, searching for the tree 

 which has the best figs, and so troublesome do they become in the im- 

 mediate vicinity of Charleston, that it is found necessary to station a 

 man near a fig tree with a gun. They also eat pears, as well as vari- 

 ous kinds of huckleberries.
