The blue grosbeak (Passerina caerulea), is a medium-sized North American passerine bird in the cardinal family Cardinalidae. It is mainly migratory, wintering in Central America and breeding in northern Mexico and the southern United States. The male is blue with two brown wing bars . The female is mainly brown with scattered blue feathers on the upperparts and two brown wing bars.

Taxonomy

The blue grosbeak was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Loxia caerulea. [2] The specific epithet caerulea is the Latin word for "blue", "azure-blue", "sky-blue" or "dark-blue". [3] Linnaeus based his own description on the "blew gross-beak" described and illustrated by Mark Catesby in his The Natural History of Carolina, Florida and the Bahama Islands. The book had been published in 1729–1732. [4] Catesby gave the location as Carolina and Linnaeus specified America. The type location is now restricted to South Carolina. [5]

Some taxonomists placed the blue grosbeak in its own monotypic genus Guiraca but in 2001 a molecular phylogenetic study of mitochondrial DNA sequences found that the blue grosbeak, in spite of being physically larger, nested within the Passerina and was most closely related to the lazuli bunting. [6] The species is therefore now placed with the North American buntings in Passerina , a genus that was introduced by the French ornithologist Louis Pierre Vieillot in 1816. [7] [8]

Seven subspecies are recognised: [8]

Description

The male blue grosbeak is deep blue, with both black and brown on its wings. The female is mostly brown. Both sexes are distinguished by their large, deep bill and double wing bars. These features, as well as the grosbeak's relatively larger size, distinguish this species from the indigo bunting. Length can range from 14 to 19 cm (5.5 to 7.5 in) and wingspan is from 26 to 29 cm (10 to 11 in). [9] [10] Body mass is typically from 26 to 31.5 g (0.92 to 1.11 oz). [11]

Distribution and habitat

This is a migratory bird, with nesting grounds across most of the southern half of the United States and much of northern Mexico, migrating south to Central America and in very small numbers to northern South America; the southernmost record comes from eastern Ecuador.

This species is found in partly open habitat with scattered trees, riparian woodland, scrub, thickets, cultivated lands, woodland edges, overgrown fields, or hedgerows.

Behaviour and ecology

Breeding

The blue grosbeak nests in a low tree or bush or a tangle of vegetation, usually about 1–2.5 m (3.3–8.2 ft) above ground, often at the edge of an open area. [12]

Feeding

It eats mostly insects, but it will also eat snails, spiders, seeds, grains, and wild fruits. The blue grosbeak forages mainly on the ground. [13]

<span class="mw-page-title-main">Oystercatcher</span> Genus of birds

The oystercatchers are a group of waders forming the family Haematopodidae, which has a single genus, Haematopus. They are found on coasts worldwide apart from the polar regions and some tropical regions of Africa and South East Asia. The exceptions to this are the Eurasian oystercatcher, the South Island oystercatcher, and the Magellanic oystercatcher, which also breed inland, far inland in some cases. In the past there has been a great deal of confusion as to the species limits, with discrete populations of all black oystercatchers being afforded specific status but pied oystercatchers being considered one single species.

<span class="mw-page-title-main">Cardinalidae</span> Bird family

Cardinalidae is a family of New World-endemic passerine birds that consists of cardinals, grosbeaks, and buntings. It also includes several other genera such as the tanager-like Piranga and the warbler-like Granatellus. Membership of this family is not easily defined by a single or even a set of physical characteristics, but instead by molecular work. Among songbirds, they range from average-sized to relatively large, and have stout features, some species with large, heavy bills.

The common reed bunting is a passerine bird in the bunting family Emberizidae, a group now separated by most modern authors from the finches, Fringillidae. The genus name Emberiza is from Old German Embritz, a bunting. The specific schoeniclus is from Ancient Greek skhoiniklos, a now unknown waterside bird.

The yellow-billed cuckoo is a member of the cuckoo family. Common folk names for this bird in the southern United States are rain crow and storm crow. These likely refer to the bird's habit of calling on hot days, often presaging rain or thunderstorms. The genus name is from the Ancient Greek kokkuzo, which means to call like a common cuckoo, and americanus means "of America".

The hairy woodpecker is a medium-sized woodpecker that is found over a large area of North America. It is approximately 250 mm (9.8 in) in length with a 380 mm (15 in) wingspan. With an estimated population in 2020 of almost nine million individuals, the hairy woodpecker is listed by the IUCN as a species of least concern. Some nomenclature authorities, such as the eBird/Clements checklist, place this species in the genus Dryobates.

<span class="mw-page-title-main">Indigo bunting</span> Species of bird

The indigo bunting is a small seed-eating bird in the cardinal family, Cardinalidae. It is migratory, ranging from southern Canada to northern Florida during the breeding season, and from southern Florida to northern South America during the winter. It often migrates by night, using the stars to navigate. Its habitat is farmland, brush areas, and open woodland. The indigo bunting is closely related to the lazuli bunting and interbreeds with the species where their ranges overlap.

The mourning dove is a member of the dove family, Columbidae. The bird is also known as the American mourning dove, the rain dove, the chueybird, colloquially as the turtle dove, and it was once known as the Carolina pigeon and Carolina turtledove. It is one of the most abundant and widespread North American birds and a popular gamebird, with more than 20 million birds shot annually in the U.S., both for sport and meat. Its ability to sustain its population under such pressure is due to its prolific breeding; in warm areas, one pair may raise up to six broods of two young each in a single year. The wings make an unusual whistling sound upon take-off and landing, a form of sonation. The bird is a strong flier, capable of speeds up to 88 km/h (55 mph).

<span class="mw-page-title-main">Grosbeak</span> Form taxon of passerine birds

Grosbeak is a form taxon containing various species of seed-eating passerine birds with large beaks. Although they all belong to the superfamily Passeroidea, these birds are not part of a natural group but rather a polyphyletic assemblage of distantly related songbirds. Some are cardueline finches in the family Fringillidae, while others are cardinals in the family Cardinalidae; one is a member of the weaver family Ploceidae. The word "grosbeak", first applied in the late 1670s, is a partial translation of the French grosbec, where gros means "large" and bec means "beak".
