My colleague Steve Pruett-Jones called my attention to a remarkable phenomenon: an albino ruby-throated hummingbird (Archilochus colubris; the only native hummer that breeds east of the Rockies). These photos are from DiscoveryNews, and were taken in Virginia. The bird appears to be a true albino since it has pink eyes.
Albinism, seen in many species of animals, results from the inability to synthesize the pigment melanin.
