Grosbeaks are birds that are known for their sturdy looking build and thick bill. While they all share a similar appearance, grosbeaks are actually comprised of birds from two separate groupings. Out of five species of grosbeaks that live in the continental United States, three of them are technically in the cardinal family along with birds like tanagers, and the other two are in the finch family.
In South Carolina there are two species that can be found on an annual basis. Here is everything you need to know about them.
Blue Grosbeak
Identification
As their name suggests, male Blue Grosbeaks are a deep blue color. They have a gray bill, small black mask, and two rusty wing bars. Females and immature males are orangey brown with faint wing bars still visible.
Range
Blue Grosbeaks spend the winter in Central America and Mexico. Some of them stay in Mexico year-round while others move north into the United States where they can be found in the southern states as well as the Great Plains States for the duration of the summer.
Diet and Foraging Habits
Blue Grosbeaks eat a combination of insects and seeds. They will also eat other invertebrates such as spiders and snails.
Where to Find This Bird
Blue Grosbeaks are most at home in open areas such as scrub and desert. They are also fond of edge habitats where they can hide in trees and thickets while singing.
Rose-breasted Grosbeak
Identification
Rose-breasted Grosbeaks are dapper looking birds with a thick bill. Males have a black head, back, tail and wings with white markings also appearing on the wings. They have a white underside with their most noticeable feature appearing on their chest: A namesake bright red marking. Females have a mottled brown back with a yellowish underside and a white eyebrow stripe.
Range
Rose-breasted Grosbeaks migrate annually from Northern South America, Central America, and Southern Mexico into the Eastern United States. In summer, they end up in the Northeastern U.S. and parts of Southern Canada.
Diet and Foraging Habits
Rose-breasted Grosbeaks feed on different food items depending on the time of the year. During spring and summer, insects make up a large portion of their diet. While in fall, berries and other fruits become more of a staple. They will also eat seeds and other plant matter.
Where to Find This Bird
Rose-breasted Grosbeaks live in a variety of habitats including deciduous and mixed conifer woods, forest edges, areas with streams and other water sources, and in backyards. They will also visit both seed and fruit bird feeders, so this is a species that can be attracted to parks, backyards, and nature centers.
Summary
Grosbeaks are beautiful and popular birds to both birders and backyard bird lovers. Knowing more about the species that are expected in your area can be instrumental in finding and identifying them, especially since they have such irregular migratory patterns.
