a nest there, May 28, 1912, which contained 3 eggs. At 

 Ramah, June 4, 1898, nests contained young and eggs in ad-

 in trees and bushes, on the ground, and even in haystacks. 



Q^iscaIu8 quiscula aeneus. Bronzed Crackle. 



Summer resident; only locally common. Arrives the last 

 of April, the earliest date being April 19, 1899. Departs early

 town, always going in flocks and feeding in the yards and

 Grosbeaks, from which he killed five males. Both sexes were

 feed on the larvae of insects that were devouring the leaves 

 of the oaks. The contents of the gizzard of one bird examined
