RUBY-THROATED HUMMINGBIRD
Archilochus colubris
Ruby-throated Hummingbirds, Archilochus colubris, are probably the most common hummingbird in the world. They have the widest distribution of any hummingbird species, ranging from southern and central Canada in summer to as far south as northern Panama in winter. This is the only hummingbird species that breeds in the eastern U.S. The adult male, with his bright red metallic gorget, gives the species its name, although other hummers in the central and western U.S. also have red throats and sometimes are INCORRECTLY referred to as "ruby-throats." Through Operation RubyThroat: The Hummingbird Project, more than 3,600 Ruby-throats have been banded at Hilton Pond Center for Piedmont Natural History near York, South Carolina, and hundreds more have been banded at other sites. FIELD MARKS: Details about identifying RubyThroated Hummingbirds are at External Characteristics. |

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. |
