The Blue Grosbeak (Passerina caerulea) is native to North and Central America. Its geographical distribution includes the southern United States, extending through Mexico and into Central America. During the breeding season, it is predominantly found in the southern parts of the U.S., while in winter, it migrates to Central America and occasionally northern South America.

The Blue Grosbeak typically inhabits open woodland areas, shrubby fields, and overgrown fields that provide both cover and feeding opportunities. It is often found in habitats such as riparian thickets, edges of deciduous and mixed woodlands, and brushy areas along roadsides.

As a seed and insect eater, the Blue Grosbeak plays a role in controlling insect populations and seed dispersal in its ecosystem. It prefers areas with abundant ground cover and tall grass for nesting and feeding, which allows access to its primary diet while providing protection from predators.
