Psaltriparus minimus, commonly known as the Bushtit, is native to western North America. Its range extends from the Pacific coast of southern British Columbia in Canada, through the United States including states such as Washington, Oregon, California, and into northern Mexico.

Bushtits inhabit diverse environments ranging from sea level to elevations of around 3,500 meters. They are typically found in open woodlands and forests, particularly those with deciduous trees and scrubby understories. These birds adapt well to suburban areas, where they frequent gardens and parks. Climate-wise, they prefer temperate zones with mild winters and comparatively warm summers.

Bushtits are small, social, non-migratory songbirds that play a crucial role in controlling insect populations, as their diet mainly consists of insects and spiders. They are often seen in large flocks, engaging in cooperative foraging that enhances their feeding efficiency and survival. The dense foliage of their habitats offers protection from predators and weather conditions.
