Painted Bunting

The painted bunting is a member of the cardinal family. It is known for its bright, colorful plumage. Males will develop this coloration during their second year. During their first year, they have a similar appearance to females.

Painted Bunting Amazing Facts

• It is also called the Mexican canary or painted finch.
• Their French name, nonpareil, means “without equal” — a reference to their beautiful plumage. 
• Illegal capture and trade are some of the largest threats to breeding populations around the world.
• They have a migration-molt pattern more similar to waterfowl than other songbirds.

Where to Find the Painted Bunting

During the breeding season, the painted bunting prefers to inhabit dense brush located near woodlands or grassy regions. This preference continues into their migratory periods and outside of the breeding season, but they may also choose to inhabit the understory of semi-open forests during this time.

There are no significant year-round populations of the painted bunting in the western hemisphere. It is native to North America, where it can be found from the southern United States to Panama.

During the breeding season, the painted bunting prefers to exist in the northernmost extent of its range. This includes around a dozen American states as well as around four Mexican states. Much of their breeding territory is centered in and around Texas, though they are also common in the coastal regions of the far eastern United States. 

While migrating, painted buntings can be seen in a larger area. This includes certain American states that lack a breeding population, such as Alabama. They can also be spotted throughout central Mexico.

Outside of these two time periods, the painted bunting is common in the southernmost regions of Mexico and throughout Central America. They can also be found in the southern tip of the Florida peninsula as well as in Cuba, the Bahamas, and the surrounding archipelagos.

Painted Bunting Nests

After a mating pair comes together, both the male and female will search for a nesting site together. They prefer areas with dense foliage, nesting between three and six feet from the ground. When such a location is unavailable, the painted bunting will often prefer to nest higher, with some individuals building nests as high as 50 feet from the ground.

Regardless of nesting height, painted buntings prefer certain plants located near perching branches. Some of the most common nesting plants include:

• Spanish moss
• Mulberry
• Mesquite
• Elm
• Osage-orange
• Greenbrier
• Oak
• Myrtle
• Pine

Once the pair determines a nesting location, the female will build the nest in as little as two days. The cup of the nest is small: around 2 inches wide and 1.5 inches deep. She forms this cup from a variety of organic materials, including twigs, rootlets, leaf skeletons, weeds, and grass that she weaves together. The entirety of the nest is bound with cobwebs, and when available, she will line the inside with fur or animal hair. This is especially true of painted buntings, which choose their nesting locations near farmland and have access to horse hair, a preferred lining.                      

Painted Bunting Scientific Name

The species name for the painted bunting is Passerina ciris. 

There are two subspecies of the painted bunting. Passerina ciris ciris is the nominate species. Its breeding grounds are in the southeastern region of the United States. Passerina ciris pallidior breeds in the south-central region of the United States as well as in northern Mexico.

Painted Bunting Size, Appearance, and Behavior

Painted buntings are small birds, similar to finches. They grow to be between 4.7 and 5.1 inches in length, and adults weigh anywhere from 0.5 to 0.7 ounces on average. Despite their compact size, they sport a wingspan almost double the length of their body, ranging from 8.3 to 9.1 inches from wingtip to wingtip.

Males of the species are the most notable, as well as the easiest to identify. They have a bold red circle around their eye, which contrasts greatly with the rich blue coloration of their heads. Their throats and chests match the red color of the eye ring, as do their tails. Their backs are green.

Females and juvenile males lack this bold coloration. Instead, they sport a green plumage all over. While this may not be as striking as the male’s coloration, it is still possible to identify females from other similarly-colored species due to the saturation of their plumage. Their green color is often much brighter than other species. 

Painted buntings have thick beaks designed for eating seeds. As a result, they can often be spotted foraging along the ground or at feeders. They prefer dense coverage while eating. 

Adult males often venture out onto perches to sing. They are also highly territorial and are known to fight with other males. These fights include pecking and hitting one another with their wings. These fights aren’t only between two males, either: males will also occasionally attack females.

Migration Pattern and Timing

This species is a medium-to-long-distance migratory bird. A rare occurrence, painted buntings from the western areas will settle in areas such as Arizona to molt before continuing their migration south. Eastern populations molt before migrating away from their breeding areas.

This species will migrate at night. They are often seen grouping with other species of birds.

Painted Bunting Diet

For the majority of the year, these birds only eat seeds. However, as they creep into breeding season, they begin to incorporate more animals into their diet. This includes insects, arachnids, and gastropods. 

What Does the Painted Bunting Eat?

Painted buntings will often be seen foraging for seeds. This includes seeds from:

• Bristle grass
• Pigweed
• Wood sorrel
• St. John’s wort
• Sedge
• Pine
• Rose
• Wheat
• Fig

As they move into breeding season, they are much more likely to hunt. Some of their most common prey include:

• Spiders
• Snails
• Grasshoppers
• Beetles
• Wasps
• Flies
• Caterpillars

Painted Bunting Predators and Threats

Painted buntings, in recent decades, have faced a decline in their population. This is due to the variety of threats that endanger individuals, including human threats and predators. 

One of the biggest threats to the painted bunting populations, as with many migratory birds, is habitat loss. In both the United States and Mexico, deforestation and urbanization have resulted in a large amount of habitat loss in the areas where this species most often frequents. 

What Eats the Painted Bunting?

Outside of human threats, predators also pose a threat to this species. One of the most common predators of the painted bunting is snakes. Some of the species most likely to target nests, young, and adults include:

• Coachwhip snake (Masticophis flagellum)
• Common king snake (Lampropeltis getulus)
• Black racer (Coluber constrictor)
• Rat snake (Elaphe obsoleta)

Painted Bunting Reproduction, Babies, and Lifespan

The mating season begins with males and their elaborate courtship displays. When a male seeks to woo a female, he does so with intense enthusiasm and dedication. He will often perform small dances and show off his bright plumage. The most notable move they use to show off their colorations is fanning out their feathers, much like a turkey would, although their display is a fraction of the size.

Painted buntings are typically monogamous. However, males may protect as many as two females in their territory. 

Once they choose their nesting location and the female builds the nest, she will lay between three to four eggs. There can be anywhere from one to three broods per year. These eggs are less than an inch in both length and width, and they have a greyish-blue exterior with small speckles of grey or brown.

The incubation period for painted buntings is 11 to 12 days. Their offspring are born completely helpless with only a small amount of down. They remain in the nest for around 9 days before leaving. Molting begins 15 to 18 months after the young are born.

The painted bunting can live to be up to 10 years old, although this age is rare for wild specimens. 

Painted Bunting Population

It is estimated that the painted bunting population currently sits at 15 million individuals. Between 1966 and 2019, their population experienced a drop of 33 percent. Despite this, they are still classified as a species of least concern.
