American Robin(Partial Albino or Leucistic?)
Photographed from my kitchen window in Salt Lake City, Utah.
For some reason, albinism and partial albinism have been recorded in robins more than any other wild bird species. One study found that 8.22% of all albino wild birds found in North America were robins. But only about one robin in 30,000 is an albino or partial albino. Most records of robins with albinism are only partial albinos, which of course live longer than total albinos. All white birds (albinos) have a complete loss of pigment, but they are very noticeable to predators so don't last long in the wild. Albinism is caused by a genetic defect carried in both the parents.
