poses, is that they never pay any attention to the presence of the Cow BLxckbirds. These 

 latter named birds, when mature, never disturb any eggs or young of other species, which 

 may account for the forbearance on the part of those deceived; thus while the predatory 

 Cuckoos and Jays are greeted with loud cries and driven from the place, the Cow Black- 

 birds pass unnoticed, although they ihvubtlessly kill more young birds than all other species- 

 combined. 



I have mentioned that eggs of the Cow Birds vaiy considerably, this would suggest 

 the idea tliat they approximate in size and markings with tliase of the birds in whose nests 

 they are dejiosited. This is not so acconling to my oteervations, yet I would not be 

 surprised if, upjn careful examination and comparison of a large number of specimens,, 

 that they did in a measure agi*ce, at least in color. This species derives its common and 

 Latin names from its habit of associating with cattle. They usually settle around cows in 

 a pasture for the purpose of catching grasshoppers which are started by the movements of 

 these animals, and of which the birds are very fond. Our little friends appear to be on 

 excellent terms with their large associates, for they may often be seen perched on their 

 backs. 



During early autumn the Cow Blackbirds assemble in large flocks on the coast in order 

 to feed on locusts, and migi'atc early in October, accompanied by Red -winged and Crow 

 Blackbirds.
