Geographic Range
Painted bunting breeding range is divided into a western and an eastern population.The western population ranges from Kansas south to Louisiana and Texas. The eastern population is limited to the coastal regions of North Carolina south to northern Florida. The western population winters primarily in Mexico and as far south as Panama. The eastern populations winter in southern Florida, including the Florida Keys, and are occasionally seen to winter in the Bahamas and Cuba (Lowther et al. 1999).
Biogeographic Regions:
nearctic
(native
); neotropical
(native
).
Habitat
The western population's breeding habitat consists of partially open areas scattered with brush, riparian thickets and shrubbery. The eastern population's breeding habitat consists of scrub communities and the margins of maritime hammocks.
Wintering habitat is similar for both the western and eastern populations, consisting of tropical forest margins and tropical savanna.
Foraging habitat is the same as either their breeding or wintering habitat. During migration foraging can occur in mixed flocks with indigo buntings
(Kaufmann 1996, Lowther et al. 1999).
Terrestrial Biomes:
savanna or grassland
; scrub forest

Physical Description
(0.46 to 0.67 oz; avg. 0.56 oz)
Painted buntings are small brightly colored birds. They are 12 to 13cm in length with an average body weight of 16 grams. Adult birds are dimorphic, the males being brightly colored. The head and nape of the males is blue, the back is bronze-green and the rump and underparts are red.The females are less brilliantly colored having dark greenish upperparts and yellow-green underparts.The wings and tail of both the male and female are dark brown or black contrasting with the rest of the body. The feet and legs, eyes and bill of both sexes are dark in color. The feet and legs are dull to dusky brown, the eyes are dark brown to hazel and the bill is dark brown to blackish in color. Plumage of juvenile birds resembles that of the adult female. The males differentiate from the females during their second year where they begin to exhibit the blue feathers on their head (Lowther et al. 1999).
Some key physical features:
endothermic
; bilateral symmetry
.
Reproduction
The breeding season begins in late April through to early August peaking mid-May through to mid-July. Males usually arrive at the breeding territory one week before the females. Pairs are usually monogamous with rare instances of polygyny. Nests are located in low lying vegetation. The nests are built by the females and woven into the surrounding vegetation for strength. The females raise two broods per season laying between 3 and 4 eggs per brood. The eggs are incubated for a period of 11 days until the altricial young hatch. Parental care of the young is solely the female's responsibility until fledging occurs 12-14 days later . Time between fledging in the first nest to the second nest is around 30 days (Kaufman 1996; Lowther et al. 1999).
Key reproductive features:
iteroparous
; gonochoric/gonochoristic/dioecious (sexes separate); sexual
; oviparous
.
Behavior
Painted buntings are a social species where males are involved in vocal exchanges lasting for 30 seconds or more. The song serves as a means for self advertisement and/or territory defense during the mating season when the males become highly territorial. Young male buntings tend to wander until their own breeding territory can be established.
Painted buntings use a variety of visual displays (upright display, body-fluff display, bow display and wing-quiver display) especially during agonistic behavior and courtship displays during the mating season. Other forms of display are incorporated into unique flight patterns such as butterfly flight (slow,undulating flight with deep wing beats) and moth flight (slow descending flight that can incorporate the wing quiver display). The majority of the displays are exhibited by the males.
Main predators of painted buntings are snakes, primarily the coachwhip snake (Masticophis flagellum), common king snake (Lampropeltis getulus), racer (Coluber constrictor) and the rat snake (Elaphe obsoleta). Predatory response includes alarm calls and frantic fluttering.
Painted buntings are nocturnal, short to medium distant migrants. Fall migration runs from the end of July to mid October and the return trip in spring begins early April and lasts until mid May. The western populations undergo a mid-migrant molt in southern Arizona and northern Mexico (outside of both thier breeding and wintering habitat) before reaching thier wintering grounds in Mexico and Central America. The eastern population molts prior to migration and travels directly to their wintering grounds in southern Florida, the Bahamas and Cuba.

Key behaviors:
flies; motile
.
Food Habits
Painted buntings are diurnal foragers, mainly feeding on grass seeds (Panicum spp., Amaranthus spp., Oxalis spp., Euphorbia spp. and Carex spp.) when in the wintering habitat and arthropods (grasshoppers[Orthoptera], caterpillars [Lepidoptera larvae], spiders [Arachnida] and snails [Gastropoda]) in their breeding habitat. The majority of food is foraged from the ground with some seeds being taken directly from the grass stalk. Painted buntings have also been observed stealing prey caught in spider webs (Kaufmann 1996; Lowther et al. 1999).
Economic Importance for Humans: Positive
Painted buntings are highly desired as caged birds due to their brightly colored plumage. Painted buntings are trapped and sold in large numbers in Central America and exported from New Orleans , by ship, to Europe where they are sold for greatly inflated prices. (Lowther et al. 1999)
Conservation Status
IUCN Red List: [link]:
Near Threatened.
US Migratory Bird Act: [link]:
Protected.
US Federal List: [link]:
No special status.
CITES: [link]:
No special status.
State of Michigan List: [link]:
No special status.
Overall there has been a general decline in painted bunting numbers since the mid 1960's. Their desirability as caged birds and loss of habitat is the primary cause of their decline. Painted Buntings are still trapped and sold in Central America and transported over-seas by ship. Habitat destruction constitutes the main reason for their decline. Development of coastal swamp thickets and woodland edges has significantly reduced their eastern coastal habitats. The loss of mid-migratory staging areas (riparian habitat) in southwest USA and in northwest Mexico have contributed to the western population decline. To a lesser extent brood parasitism by cowbirds (Molothrus ) contributes to the Painted bunting's decline. The painted bunting is currently listed on Partners in Flight Watchlist as a species of special concern (Kaufmann 1996, Lowther et al. 1999).
Painted buntings are listed as near-threatened by the IUCN, and they are protected by the U.S. Migratory Bird Act.
Other Comments
Painted buntings are also known by the French as Passerin nonpareil meaning without equal (Lowther et al. 1999). "According to an American Indian legend, when the great spirit was giving all the birds thier colors, he ran short of dye so he gave the very last one, the painted bunting, a coat of many colors made from dabs of whatever was left." (Pope 1991)
