The painted bunting (Passerina ciris) is a species of bird in the cardinal family, Cardinalidae, that is native to North America. The bright plumage of the male only comes in the second year of life; in the first year they can only be distinguished from the female by close inspection.

Taxonomy

The painted bunting was originally described by Carl Linnaeus in his eighteenth-century work Systema Naturae.[2] There are two recognized subspecies of the painted bunting:[3][4]

Description

Painted Bunting from The Birds of America

The male painted bunting is often described as the most beautiful bird in North America and as such has been nicknamed nonpareil, or "without equal".[5] Its colors, dark blue head, green back, red rump, and underparts, make it extremely easy to identify, but it can still be difficult to spot since it often skulks in foliage even when it is singing. The plumage of female and juvenile painted buntings is green and yellow-green, serving as camouflage. Once seen, the adult female is still distinctive, since it is a brighter, truer green than other similar songbirds. Adult painted buntings can measure 12–14 cm (4.7–5.5 in) in length, span 21–23 cm (8.3–9.1 in) across the wings and weigh 13–19 g (0.46–0.67 oz).[6][7]

The juveniles have two inserted moults in their first autumn, each yielding plumage like an adult females. The first starts a few days after fledging replacing the juvenile plumage with an auxiliary formative plumage; the second a month or so later giving the formative plumage.[8]

Distribution and habitat

The painted bunting occupies typical habitat for a member of its family. It is found in thickets, woodland edges with riparian thickets, shrubbery and brushy areas. In the east, the species breeds in maritime hammocks and scrub communities. Today, it is often found along roadsides and in suburban areas, and in gardens with dense, shrubby vegetation. The wintering habitat is typically the shrubby edges along the border of tropical forests or densely vegetated savanna.[9] The breeding range is divided into two geographically separate areas. These include southern Arizona, southern New Mexico, southern and eastern Texas, Oklahoma, Arkansas, Louisiana, northern Florida, coastal Georgia, the southern coast and inland waterways such as the Santee River of South Carolina and northern Mexico.[1] They winter in South Florida, Cuba, the Bahamas, along both coasts of Mexico and through much of Central America. Occasionally, they may be vagrants further north, including to New York[10][11] Pennsylvania[12] and New Jersey.[13] The bird is also found every few years as far north as New Brunswick, Canada.[14]

Behavior

Painted buntings are shy, secretive and often difficult to observe for the human eye, though can be fairly approachable where habituated to bird feeders. Males sing in spring from exposed perches to advertise their territories. They also engage in visual displays including flying bouncingly like a butterfly or in an upright display, body-fluff display, bow display and wing-quiver display. These displays are used in agonistic conflicts with other males or in breeding displays for females, with females rarely engaging in displays. Occasionally, males may physically clash with each other and may even kill each other in such conflicts.[6] When their breeding season has concluded, buntings migrate by night over short to medium distances. Western birds (Arizona and northern Mexico) molt in mid-migration, while eastern birds tend to molt before they migrate.[9]

Feeding

Painted buntings often feed by hopping along the ground, cautiously stopping every few moments to look around. The painted bunting regularly eats a large quantity of grass seeds, including; Panicum, Amaranthus, Oxalis, Euphorbia and Carex. Seeds are eaten almost exclusively during winter. While breeding, painted bunting and nestlings mainly eat small invertebrates, including; spiders, snails, grasshoppers, caterpillars and other insects. They have been known to regularly visit spider webs to pick off small insects caught in them.[9]

Breeding

Painted buntings are mostly monogamous and are solitary or in pairs during the breeding season, but sometimes exhibit polygyny. The breeding season begins in late April and lasts through to early August, with activity peaking mid-May through to mid-July. The male arrives about a week before the female and starts to establish a small territory. The nest is typically hidden in low, dense vegetation and is built by the females and woven into the surrounding vegetation for strength.[9] Each brood contains three or four gray-white eggs, often spotted with brown, which are incubated for around 10 days until the altricial young are hatched. The female alone cares for the young. The hatchlings are brooded for approximately 12 to 14 days and then fledge at that time. About 30 days after the first eggs hatch, the female painted bunting usually lays a second brood.[9] Nests are often parasitized by cowbirds.[9] Common predators at the nest of eggs, young, and brooding females are large snakes, including coachwhip snakes, eastern kingsnakes, eastern racers and black rat snakes.[9] Bird-hunting raptors, including short-tailed hawks, Accipiter hawks, and even the small passerine loggerhead shrike, may hunt painted buntings, including the conspicuous breeding-plumaged male. The painted bunting can live to over 10 years of age, though most wild buntings probably live barely half that long.[9]

Status

The male painted bunting was once a very popular caged bird, but its capture and holding is currently illegal.[15] Trapping for overseas sale may still occur in Central America.[9] Populations are primarily declining due to habitat being lost to development, especially in coastal swamp thickets and woodland edges in the east and riparian habitats in migration and winter in the Southeastern United States and Mexico.[9] They are categorized as near threatened by the IUCN[1] and are protected by the U.S. Migratory Bird Act.
