Habitat

Rose-breasted grosbeaks prefer semi-deciduous or deciduous-coniferous forests, swamps, or forests along rivers. They usually avoid dry grasslands or woodlands. They breed in Northeastern America extending till southeastern and central Canada. In the winters, they prefer the southern and central areas.

Diet

They are basically insect-eating birds, but also eat seeds or wild fruits. Insects that they usually eat are beetles, bees, ants, sawflies, bugs, butterflies, and moths. Fruits they prefer are elderberries, blackberries, raspberries, mulberries, and juneberries. They also eat seeds of smartweed, pigweed, foxtail, milkweed, sunflower seeds and garden peas, wheat, oats, and tree flowers. They sometimes snag their food from dense foliage or branches. They also fly out to hawk for insects.

Call

The metallic chink is the most common call of the rose-breasted grosbeak. It also makes weep and eek-eek calls in social situations. Its songs are very melodious like American robins, but the notes are faster. They sound like a robin trained in music! The male as well as the female are beautiful songbirds, but the female usually sings a shorter and softer version than the male. Males sing while flying, to woo the female. They also sing together when nesting.

The male incubates the eggs for ⅓rd of the day. When the male and female exchange places, they sing. In fact, the male keeps on singing even when it is incubating the eggs! They love to sing on moonlit nights and prefer singing softly. Males sing to attract females and establish their territories. If a female approaches a male, he snubs her initially, but accepts her as a mate after a couple of days!

Rose-breasted grosbeaks are monogamous for a particular breeding season. They build the nest together and share incubation duties. The female usually lays 1-5 bluish-green eggs. They hatch in around 11-14 days and can fly in 9-12 days. The young are ready to breed in a year after hatching.

Migration

They migrate to warmer Southern or Central America in winters. They usually fly in large flocks and prefer high woodlands. Sometimes, they stay in thickets, second-level forests, or urban areas.

A group of grosbeaks are collectively known as a "gross" of grosbeaks.

The rose-breasted grosbeak sometimes breeds with the black-headed grosbeak in areas where both the birds are scarce. The hybrids can look like either parent.

The maximum lifespan in the wild is 7.3 years.

Rose-breasted grosbeaks have huge tough beaks. They can eat insects with a tough exoskeleton.
