Similar Species- Rose-breasted Grosbeak
Robin-like song with addition of some whirring and spik sounds; much longer than American Robin.
Breeds from portions of western Canada, northeastern Montana, and northwestern North Dakota, south along Pacific Coast to northern Baja California, central and southeastern Arizona, and eastern New Mexico, east through portions of Midwest, and further south into mainland of Mexico. Winters in Mexico.
Found in deciduous forests and woodlands, pine/oak associations, oak scrub, pinyon/juniper woodlands, and deciduous thickets. Often found on edges of ponds, streams, or forests. Results of an Idaho study in cottonwood forest indicated grosbeaks were most strongly associated with willow subcanopies and avoided grazed areas.
Feeds on insects, spiders, berries, seeds, and buds.
Builds cup-shaped nest in tree, or sometimes in shrub. Forages in crowns of deciduous trees, in shrubs, and on ground. Both male and female defend nesting territory against other breeding pairs. In New Mexico, jays are primary nest predators.
