Stellula calliope

The tiniest hummingbird north of the Rio Grande, the Calliope Hummingbird, Stellula calliope (formerly Archilochus calliope), occurs primarily in Mexico and western sections of the U.S. and Canada. In recent years it has been seen with increasing regularity in the eastern U.S. in fall and winter. In male Calliopes, the iridescent gorget (throat) feathers are elongated; in most North American hummingbirds species these feathers are fan-shaped or rounded.

Several Calliopes have been banded in the Carolinas in winter as part of Operation RubyThroat; for photos and descriptions of these birds, please see the links from Vagrant & Winter Hummingbird Banding.

If you have a sharp photo of a Calliope Hummingbird you would like to contribute for this page, please send it to PROJECTS with info about when and where the photo was taken, the photographer's name, and any anectdotal info about the bird.

NOTE: Although Ruby-throated Hummingbirds are the primary focus of "Operation RubyThroat: The Hummingbird Project", we are also interested in other hummingbird species--especially vagrants that appear in winter (mid-October through mid-March) in the eastern U.S. If you know of a wintering hummingbird east of the Mississippi, please report it to RESEARCH. We will contact a local hummingbird bander about capturing the bird, identifying and banding it, and releasing it unharmed.
