These birds primarily live year-round in the Central Valley of California, but do have some small breeding ranges in northern California, parts of central Oregon, and a small bit of Washington.

Identification

The Tricolored Blackbird is a small stocky songbird with glossy feathers, round head, and a short triangular beak. Males are a stunning jet black, with feathers that shine in the light. They have a patch of bright red on the top of their wings, with a line of bright yellow underneath the red, making these birds easy to spot even from great distances. Females are a dusty brown with mottled shades of tan and dark brown on their wings, back, and chest. They have pale brown streaks on their head, and a light tan throat. The songs of both males and females seem muffled, without any clear notes. The calls of these birds are nasally squeaks.

Habitat

Tricolored Blackbirds primarily breed in freshwater marshes and agricultural fields, particularly in wheat, rye, and other grain fields. They also forage in a variety of habitats including grasslands, pastures, and feedlots. Historically they nested in wetlands, but due to habitat loss, now utilize agricultural areas, which can create conflicts with farming practices.

Conservation Status 

Threats to Conservation

Tricolored Blackbirds face several significant threats to their conservation, primarily stemming from habitat loss and breeding disruptions. These include habitat loss due to development and agricultural practices, large-scale breeding failure in harvested agricultural fields, and vulnerability to human disturbance. Loss of historic wetlands and marshes limit the options parent birds have, even when faced with consistent failure to raise chicks in a particular location year after year.
