Habitat Comparison
Anna's Hummingbird
Chaparral, coastal sage scrub, gardens, parks, and open woodland along the Pacific coast. One of few hummingbirds not fully migratory.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
Song & Call Comparison
Anna's Hummingbird
Male produces a complex, scratchy song with buzzy 'dzzzzt' notes. Gives a nasal 'chee-chee-chee'. Males sing year-round, even in winter; one of few hummingbirds with true song.
Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.
Geographic Range & Migration
Anna's Hummingbird
Western North America from southern British Columbia along the Pacific coast to Baja California. Range has expanded northward.
Downy Woodpecker

Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
About These Birds
Anna's Hummingbird
Anna's hummingbird is the most common hummingbird along the Pacific coast and one of only three species resident in the United States year-round. Males perform spectacular dive displays, plummeting from 40 meters and pulling up with a loud chirp produced by tail feathers. Their body temperature can drop to near ambient at night to conserve energy.
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
