Western Blue Grosbeak in Northern Colorado
Western Blue Grosbeak in Northern Colorado.
While on a visit to my place August 15-20, 1901, Prof. A. H. Felger of Denver took a good specimen, a female, of Guiraca cærulea lazula, which was feeding in the orchard and the only specimen observed. There have been five or six pairs of the western blue grosbeak about the vicinity the past two weeks. I secured a few of them. They appeared to be on the move and have been observed as mated. This variety is not uncommon in some of the southeastern portions of the state, for which reason I desire to record its occurrence at this northern point.
