The mystery of the N.C. 'bluebird'
18.05.12
Birders are drawn to a bird’s plumage characteristics as an initial means of identification. This is understandable; plumage is generally unique to a species and is all that is required to clinch a quick and easy identification. Occasionally, however, a situation arises where other means of identification are needed, or at least need to be considered.
Such a recent challenge has come from North Carolina and has received much discussion nationwide in birding circles. Even David Sibley, author of “The Sibley Guide to Birds,” offered an opinion.
A bluebird was photographed in Fayetteville that lacked the characteristic reddish coloring on the underparts of the familiar Eastern bluebird. Initial thought was that it could be a mountain bluebird, a western species that does rarely occur in the East and has occurred in North Carolina just one time. That species lacks the reddish plumage of an Eastern bluebird. Some folks who viewed photos of the bluebird were unconvinced, however, and brought up questions of the bird’s structure.
