ao BIRDS OF LA PLATA 



in spring scattered about the plantation, screaming 

 and chattering in their usual manner when about 

 to breed. I watched them, and found that after a 

 time the flock broke up into small parties of three 

 or four, and not into couples, and I could not detect 

 them building. At length I discovered three broken 

 eggs on the ground, and on examining the tree

 eggs had been dropped. This was in October, and

 nests were made, each nest by one pair of birds, and 

 in the two fourteen or fifteen young birds were 

 reared. 



When taken young the Guira Cuckoos become 

 very tame, and make bold, noisy, mischievous pets,

 cloth. In a wild state their food consists largely of 

 insects, which they sometimes pursue running and 

 flying along the ground. They also prey on mice 

 and small reptiles, and carry off the fledglings from
