Blue Grosbeak

The Blue Grosbeak is a migratory bird, with nesting grounds across most of the southern half of the United States and much of northern Mexico. It eats mostly insects, but it will also eat snails, spiders, seeds, grains, and wild fruits. The Blue Grosbeak forages on the ground and in shrubs and trees.

The Blue Grosbeak is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

Distribution of the Blue Grosbeak in North and Central America. The Blue Grosbeak is a large bunting of the southern forest edge, often seen singing from roadside wires and tree tops. Although widespread throughout its breeding range, it is generally scarce and virtually all aspects of its biology are poorly known, perhaps owing in part to its low numbers. More

Blue Grosbeak (Passerina caerulea, formerly Guiraca caerulea), is a medium-sized seed-eating bird in the same family as the Northern Cardinal, "tropical" or New World buntings, and "cardinal-grosbeaks" or New World grosbeaks. The Blue Grosbeak is a migratory bird, with nesting grounds across most of the southern half of the United States and much of northern Mexico. It eats mostly insects, but it will also eat snails, spiders, seeds, grains, and wild fruits. More

Blue Grosbeaks are large buntings of forest edge with a widespread breeding range in North America, Mexico and Central America. The males are often seen singing from roadside wires and tree tops. While the breeding biology of this bird is likely similar to its relative, the Indigo Bunting, there is little detailed information about Blue Grosbeak nesting ecology, courtship behavior and song structure available.

The Blue Grosbeak has a very large range, extending to around 5,300,000 square kilometers and can be found in subtropical and tropical forest or shrubland ecological systems. It is primarily found in North, Central, and South America, but has been seen in places such as Barbados and the Cayman Islands. The global population is believed to be about 7,700,000 birds and does not meet the criteria for the IUCN Red List. The Blue Grosbeak currently has an IUCN evaluation level of Least Concern. More

Blue Grosbeaks nesting in the U.S. winter in Mexico and Central America, and many of them migrate through the Caribbean to get there. There are records of Blue Grosbeaks at bird feeders in winter in the northern U.S., though few of these birds probably survive until spring. Follow the link on the left for additional information.

The Blue Grosbeak is often mistaken for its relative, the Indigo Bunting. Indigo Buntings are smaller overall, have a smaller bill, and the adult male lacks the wing bars present in the Blue Grosbeak. Both male and female Blue Grosbeaks have the habit of spreading and flicking their tails, and occasionally raising the feathers on the crown, giving the head a shaggy appearance. SPECIES DESCRIPTION - Length: 15. More

Central America, the Blue Grosbeak is migrating north to its breeding range, which extends over much of the southern half of the United States. Blue GrosbeakGuiraca caerulea The husky warbling song of the Blue Grosbeak is a common sound in summer around thickets and hedgerows in the southern states. Often the bird hides in those thickets; sometimes it perches up in the open, looking like an overgrown Indigo Bunting, flicking and spreading its tail in a nervous action. More

The California Blue Grosbeak is restricted to the Lower Sonoran Zone where it lives in the low dense thickets of willow on the bottom lands of the big rivers. It is therefore not likely to come to the attention of the mountain-seeking visitor unless he should stop off at some place in the lowlands and make special search for the bird. More

Reported densities are 30 males/km2 in Florida (Baker 1989 in Ingold 1993), and 31 males/km2 in e TX (Dickson Segelquist 1979 in Ingold 1993). BBS data from map in Ingold indicates CA densities to be less than 5 birds per route per year. Along the Colorado River, densities are reported as 4 to 6 pairs/40 ha (Rosenberg 1991). In Orange Co.

Blue Grosbeaks are somewhat secretive but can be found across Tennessee during the summer months. They arrive by the end of April and depart by the end of September, and occur in brushy fields, and hedgerows adjoining grasslands and croplands. Interestingly, they only started nesting in Tennessee in 1945, and had spread across the state by the mid-1960s. The reasons for this dramatic range expansion are unknown. More
