The painted bunting is a small, colorful songbird that can be found in the southeastern United States during the warmer months. In the winter, they migrate south to Mexico, Central America, and the Caribbean. Painted buntings prefer brushy, semi-open habitats like forest edges, hedgerows, and thickets. Their bright, vivid colors make them stand out against the green foliage.
What is the range of the painted bunting?
The painted bunting has a relatively small range confined to the southeastern United States, Mexico, and Central America. In the U.S., the painted bunting’s breeding range extends from southern Missouri, Arkansas, Louisiana, and eastern Texas south through Oklahoma, eastern Kansas, and along the coasts of the Gulf of Mexico to Florida. Along the Atlantic coast, their range stretches as far north as North Carolina. The highest densities are found along the Gulf coast in states like Texas, Louisiana, Mississippi, Alabama, and Florida.
During the winter months, painted buntings completely vacate their U.S. breeding grounds and migrate south to their wintering range. Most travel to Mexico, with high concentrations wintering in northwestern Mexico and along the Pacific coast. Others continue further south into Central America, reaching as far as Panama. Small numbers also winter in South Florida, the Bahamas, and the Caribbean islands like Cuba, Jamaica, Hispaniola, and Puerto Rico.

What habitats do painted buntings prefer?
Painted buntings thrive in brushy, semi-open habitats that provide a mix of dense foliage for protection and open areas and edge habitats for foraging. Typical habitats include:
- Forest edges
- Hedgerows
- Thickets
- Woodland margins
- Overgrown fencerows
- Second growth
- Forest clearings
They also inhabit scrubby vegetation in open areas like:

What is the elevation range where painted buntings occur?
Painted buntings are generally found at lower elevations within their range due to their preference for warm, coastal habitats. They occur:
- From sea level to around 1,600 feet in their breeding range
- From sea level to around 6,500 feet in their winter range
Their U.S. breeding range centers around coastal regions along the Gulf of Mexico and the southern Atlantic coast. These regions are typically low elevation areas:
- Texas coastal plain: 0-300 feet
- Louisiana coastal plain: 0-500 feet
- Mississippi lowlands: 0-300 feet
- Alabama coastal plain: sea level to 500 feet
- Georgia coastal plain: sea level to 500 feet
- Florida lowlands: 0-300 feet
Farther from the coast, they range into higher elevations up to around 1,600 feet in areas like the Ouachita and Ozark Mountains.
In their Mexican wintering grounds, most occupy lower elevations in coastal regions and valleys. But some reach up to around 6,500 feet in mountain woodlands.
Breeding Elevations
During breeding season, painted buntings occupy elevations:
- Up to 1,600 feet
- Mostly below 500 feet
Coastal areas are at elevations of:
- Sea level to 300 feet along the Gulf Coast
- Sea level to 500 feet along the southern Atlantic coast
Winter Elevations
In their winter range, most painted buntings occur at low elevations:
- Sea level to around 3,000 feet
- Some up to 6,500 feet in Mexican mountain woodlands
Typical winter elevations include:
- Coastal regions: sea level to 500 feet
- Mexican interior valleys: 2,000-6,500 feet
What types of climate are preferred by painted buntings?
The painted bunting generally prefers warm, temperate climates throughout its range. It thrives in areas with hot, steamy summers and mild winters.
Key aspects of painted bunting climatic zones include:
- Hot summers
- Mild winters
- Moderate seasonal precipitation
- Low-latitude subtropical climates
They tend to avoid colder and drier inland regions in favor of warmer coastal areas. Hard freezes and heavy snow are outside of their climatic tolerance.
Breeding Climate
During the breeding season, painted buntings are found in hot, humid, subtropical climates typical of the southeastern U.S. coast including:
- Hot, humid summers: average highs of 90°F+
- Mild winters: average lows 35-55°F
- 50-65 inches of rain per year
Winter Climate
Their wintering grounds have tropical and subtropical climates such as:
- Warm temperatures year-round
- Highs averaging 70-90°F
- Lows averaging 60-75°F
- Heavy seasonal rains
What are some key threats and conservation issues facing painted buntings?
Some key threats and issues facing painted bunting populations include:
- Habitat loss and degradation
- Development
- Agricultural intensification
- Predation
- Browning cowbird parasitism
- Pesticides
- Climate change
Habitat loss in both their breeding and wintering grounds is a major concern. Development, agriculture, and logging have reduced suitable scrubby habitats. Predation and brood parasitism also threaten productivity.
Climate change may make breeding grounds drier and impact wintering grounds. Pesticides reduce insect prey. Overall populations declined around 40% between 1966-2015 per the North American Breeding Bird Survey.
Habitat Loss
Habitat loss to development, agriculture, and logging has removed needed brushy habitats. Urbanization along the U.S. southeast coast has been a major cause of habitat decline.
Brood Parasitism
Brown-headed cowbird brood parasitism reduces reproductive success. Cowbirds lay eggs in bunting nests, reducing bunting chick survival.
Pesticides
Pesticide use has lowered insect prey populations. Painted buntings mainly eat insects during the breeding season, so less insect food affects success.
Conclusion
In summary, the brightly colored painted bunting occupies the southeastern coastal regions of the United States during the breeding season. It migrates to Mexico, Central America, and the Caribbean for the winter months. Painted buntings prefer warm, coastal regions with brushy scrub habitats. Loss of these habitats is a major threat, along with issues like parasitism and pesticides. Protecting coastal scrub habitats and insect prey are key conservation priorities for maintaining painted bunting populations.
