A Bird of a Different Color

May 19, 2011

One of the pleasures of my job is that I get to see lots of photos of unusually colored animals that Missourians submit to us for an explanation. They include individuals with no pigments (true albinos), melanistic (all or mostly dark-colored due to excess pigment) and a variety of piebald patterns where some of the normal pigments are missing, leaving white feathers or fur.

A leucistic animal can have pale colors overall or can have normal colors next to pure white areas. The presence and distribution of pigments is genetically controlled, and abnormal deposition of pigments is very rare. One study of birds at feeders recorded fewer than 1,000 leucistic birds in 38 million observations.

The leucistic American robin pictured here was observed in a neighborhood in O’Fallon, Mo., this month. It behaves like others of its species, spending much of its time in the spring hunting for earthworms in residential lawns. It makes me wonder how the other robins regard this bird that doesn’t look like them. Is it prized as a wondrous variation, like the Native Americans treated the rare albino bison? The other robins don’t seem to treat it any differently. Leucistic birds are reportedly less likely to attract mates and more likely to fall victim to predators. Those factors certainly must contribute to their rarity.

Karen:  See the link in the story, on the word "leucistic," for a discussion of the changing application of the word to include birds with white areas lacking pigment. I am following the Cornell University's definition.

According to the Oxford dictionary the definition of leucistic is "having all whitish fur, plumage or skin due to a lack of pigment." The origin of the word is "LEUCO" which means white. Therefore the bird pictured in this article is a pied, not a leucistic because a leucistic animal is all white with blue or black eyes.

We live in Imperial, MO where a white Robin female began to build a nest in our backyard but changed her mind and built it elsewher. We still see her now and then by the feeder. It would have been cool if she would have stayed
