This bri"lit blue Buntino^ is one of the most brilliant of 

 northern birds. The color of the male is so dark that at 

 a distance it seems almost black. The 

 male requires three 3'ears to attain full 

 plumage. It frequents bushy pastures, 

 sprout lands, and old fruit gardens 

 grown up to weeds. In late August 

 and September it is seen in sweet-corn 

 patches or corniields. 



Its song is a rather rich and pleas- 

 ing refrain, with a metallic ring or jingle. A few notes 

 seem to exhaust its vocabulary and its breath at the same 

 time, but it is soon ready to try again. Perseverance is its 

 unfailing virtue, for it sings, intermittently, all through the 

 long, hot summer day. Its alarm note is a sharp clu'p. 



It feeds more on the caterpillars that infest trees and 

 bushes than do most Sparrows, and takes manj^ such larvae to 

 its young. It is fond of grasshoppers, 

 and takes some insects from the garden. 



It eats the birch plant louse with avidity. 

 A few flies, mosquitoes, or gnats are 

 taken ; cankerworms and other measur- 

 ing worms, the larva? of several species of pig. 130— inciigo Bunt- 

 butterflies, and the imagoes of nocturnal mg, female. 

 and Tineid moths, with small beetles of difterent species, con- 

 stitute a portion of its insect food. The larger part of its food 

 consists of seeds, many of which are those of weeds. During 

 its short stay with us it is one of the few useful species seen 

 much about the garden, and is of some service in the orchard.
