Evening Grosbeak


Evening Grosbeaks breed in coniferous forests, but winter in a variety of woodlands.


Primarily seeds, but also some insects and berries.  Flocks of Evening Grosbeaks can empty bird feeders full of sunflower seeds very rapidly.


Evening Grosbeaks forage mostly in trees or on bird feeders, and are usually in flocks during the nonbreeding season.


Evening Grosbeaks breed in Canada and parts of the western U.S. and Mexico, and winter, at least sporadically, over large parts of the U.S. Its population has declined in recent decades.

Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.
