About the project

Celebrate Hummingbirds is a citizen science project at the Cornell Lab of Ornithology. It is part of the Celebrate Urban Birds program. Your observations will help scientists better understand how hummingbirds are using urban areas. You can participate anywhere—in cities, suburbs, or rural areas. It’s fun and easy. Hummingbirds are easy to attract and fun to observe.

How to participate

Pick a date, time, and bird-watching site BEFORE you go out to watch birds. Don’t change your site or time just because you see a hummingbird! That would bias your results. Watch for ten minutes and tell us if you see any hummingbirds. Observe on 3 different days on the same site, at about the same time, and share your observations with us. OPTIONAL: If you think you can identify the hummingbirds you saw, please do so. Let us know if you see or if you DON’T see hummingbirds. Zero means a lot!

Meet the hummingbirds!

Anna's Hummingbird

Anna’s Hummingbird

Anna’s Hummingbirds are among the most common hummingbirds along the Pacific Coast. With their iridescent emerald feathers and sparkling rose-pink throats, they are more like flying jewelry than birds.

Ruby-throated Hummingbird

A flash of green and red, the Ruby-throated Hummingbird is eastern North America’s sole breeding hummingbird.

Rufous Hummingbird

The feistiest hummingbird in North America. The brilliant orange male and the green-and-orange female Rufous Hummingbird are relentless attackers at flowers and feeders, going after even the larger hummingbirds.

Black-chinned Hummingbird

A small green-backed hummingbird of the West, with no brilliant colors on its throat except a thin strip of iridescent purple bordering the black chin, only visible when light hits it just right.

Calliope Hummingbird

The smallest bird in North America north of Mexico, the Calliope Hummingbird inhabits mountain areas of the northwestern United States.

Costa’s Hummingbird

A desert hummingbird, Costa's Hummingbird breeds in the Sonoran and Mojave Deserts of California and Arizona.

Broad-tailed Hummingbird

A hummingbird of subalpine meadows, the Broad-tailed Hummingbird ranges across the south-central Rockies in summer.

Allen’s Hummingbird

Extremely similar in appearance to the widespread Rufous Hummingbird, the Allen's Hummingbird breeds only along a narrow strip of coastal California and southern Oregon.
