Autumnal and winter males have the feathers generally, especially on the back and breast, tipped with light brown, obscuring somewhat the blue, though producing a beautiful appearance. HABITS. The Blue Grosbeak, though more a bird of the Southern States, is also one both of an extended and of an irregular distribution. It was even met with one year in the vicinity of Calais, Me., although none have been known to occur in any part of the country between that point and New York City. It is found from the Atlantic to the Pacific coast. The extent to which it is distributed throughout California is inferred, rather than known. Dr. Cooper noticed one at Fort Mohave, May 6, and afterwards saw many more frequenting the trees and bushes along the river, and singing a lively song, which he compares with that of the _Carpodacus frontalis_. He also saw them at Los Angeles and at Santa Barbara, and states that they were found at Pit River, in the extreme northeastern part of the State, by Dr. Newberry. They were observed to frequent the banks of streams crossing the great interior plains and deserts, where there was little vegetation except a few bushes. The Blue Grosbeak was only met with by Mr. Ridgway and his party at Sacramento. It does not occur—or, if so, it was not seen—in the interior so far to the north as the route of Mr. King’s survey. At Sacramento it was found frequenting the same localities as the _Cyanospiza amæna_, and appeared to be characteristic of the cottonwood copses. Their nests were found between the 18th and the 29th of June, and were all in similar situations. These were built in small cottonwood-trees, on the edge of the copse, and were all about six feet from the ground.
