Rose-breasted Grosbeak (Pheucticus ludovicianus)

27 May

Rose-breasted Grosbeaks often visit bird feeders. Breed in moist deciduous forests, deciduous-coniferous forests, thickets, and semiopen habitat. They gravitate toward second-growth woods, suburban areas, parks, gardens, and orchards, as well as shrubby forest edges next to streams, ponds, marshes, roads, or pastures.

During the breeding season Rose-breasted Grosbeaks eat a lot of insects, as well as wild fruit and seeds. They mostly feed on berries during fall migration, and on their wintering grounds they have a varied diet of invertebrates and plant material. Grosbeaks usually glean their food from dense foliage and branches. They also snag food while hovering, and sometimes fly out to hawk for insects in midair. The animal portion of their diet includes beetles, bees, ants, sawflies, bugs, butterflies, and moths. Their vegetarian fare includes elderberries, blackberries, raspberries, mulberries, juneberries, and seeds of smartweed, pigweed, foxtail, milkweed, plus sunflower seeds, garden peas, oats, wheat, tree flowers, tree buds, and cultivated fruit.

The male may help the female choose a nest site, which is usually in a vertical fork or crotch of a sapling. Nesting plants include maple, red-berried elder, balsam fir, eastern hemlock, and spruce, and may be in wet or dry areas. They are usually in forest openings, overgrown field edges, old pastures, shrubby roads, railroad rights-of-way, gardens, parks, or residential areas.
