The Cow Bunting, Cow Blackbird, or Cowpen-bird, derives its various names from the 
circumstance of its following cattle in the fields, searching in their droppings for undigested 
grains and intestinal worms. Like the Cuckoo of Europe, it deposits its eggs in the nests 
of other birds to be hatched, and, according to the testimony of some writers, never builds a 
nest of its own : the eggs pale greenish, with olive brown points and confluent blotches, more 
numerous at the larger end. This species appears in this State about the beginning of April, 
and leaves us for the South in October. Its food consists of grubs and the hard-shelled in¬ 
sects, maize and other seeds. It has been observed from Mexico to the 68th parallel.
