Rose-breasted Grosbeak
At a Glance
In leafy woodlands of the East, the Rose-breasted Grosbeak often stays out of sight among the treetops. However, its song -- rich whistled phrases, like an improved version of the American Robin's voice -- is heard frequently in spring and summer. Where the range of this species overlaps with that of the Black-headed Grosbeak on the Great Plains, the two sometimes interbreed.

Habitat
Deciduous woods, orchards, groves. Breeds mostly in open deciduous woods, sometimes in mixed woods, favoring edges or openings with combination of shrubs and tall trees rather than unbroken forest. In migration, may occur in any wooded or semi-open area. Winters in the tropics, mostly at forest edge or in second-growth woods in lowlands and foothills.

Behavior
Eggs
3-5, typically 4. Pale greenish blue, spotted with reddish brown. Incubation is by both parents, 13-14 days.
Young
Both parents feed the nestlings. Young leave nest about 9-12 days after hatching. Male may care for fledglings while female begins a new nest. 1-2 broods per year.
Feeding Behavior
Forages mostly in shrubs and trees, searching for food among foliage. Sometimes hovers to take insects from foliage or bark, or flies out to catch insects in mid-air.
Diet
Mostly insects, seeds, and berries. About half of annual diet may be insects, including beetles, caterpillars, grasshoppers, true bugs, and others, also spiders and snails. Eats many seeds, including those of trees such as elms, and sometimes eats buds and flowers. May feed heavily on berries and small fruits in late summer and fall. Young are fed mostly insects.
Nesting
Male sings to defend nesting territory, and may fight actively with intruding males. In courtship, male may partly spread wings and tail, draw head back, and approach female while singing. Nest: Placed in deciduous tree or large shrub (occasionally in conifer), usually 5-20' above ground, sometimes much higher. Nest (built mostly by female) is an open cup, rather loosely made of twigs, weeds, leaves, lined with finer twigs, rootlets, and sometimes animal hair. May be so flimsy that eggs are visible through the nest from below.
Climate Vulnerability
Conservation Status
Could be vulnerable to loss of habitat, but current numbers apparently stable.
