Do Anna’s Hummingbirds Migrate? Yes!

Yes, Anna’s Hummingbirds do migrate, but their migratory patterns are somewhat atypical. Unlike many migratory bird species, Anna’s Hummingbirds do not migrate long distances.

Instead, some populations exhibit a form of migration known as “altitudinal migration,” where birds move from higher elevations to lower ones during colder months.

Anna’s Hummingbirds (Calypte anna) are native to the West Coast of North America. Their range extends from southern Canada, down through the United States, to Baja California in Mexico.

Traditionally, they were seasonal migrants, moving to warmer regions during the winter.

However, with changes in climate and the availability of food resources like backyard feeders, many Anna’s Hummingbirds are now year-round residents in parts of their range, particularly along the Pacific Coast.

These hummingbirds may migrate in the following ways:

It’s important to note that the migratory behavior of Anna’s Hummingbirds can vary greatly based on regional conditions and individual bird behavior.

With a flash of iridescent feathers, Anna’s Hummingbirds bring dynamic beauty to their habitats, adapting their migratory habits to the changing climates they face.

Anna’s Hummingbird Overview

Anna’s hummingbirds are primarily found in the western coastal regions of North America. These tiny birds, with metallic green plumage and iridescent rose-pink throats on the males, are a common sight in gardens, woodlands, and coastal scrub.
