There are a variety of Grosbeaks seen in the United States and Canada. The Rose-Breasted Grosbeaks are seen in the summer months in the Northeast and Midwest U.S. and eastern and central Canada. The Evening and Black-headed Grosbeaks are found year round through the western parts of North American and Canada.
All the varieties prefer hulled sunflower and black oil sunflower, but will also readily eat safflower and nutrasaff. They will visit any feeder that offers them their favorite seeds. Thank you to The Macaulay Library at the Cornell Lab of Ornithology, Ithaca, New York.
