In a recent issue, David Sibley described what to look for on partial albino birds. (They’re also referred to as leucistic.) Partial albinos vary considerably; they can be almost completely white or have a few white feathers among normally colored feathers. They can also look pale tan or gray.
This ghostly Spotted Sandpiper presents an example of dilute plumage, in which feathers still have a little pigment. Paul O’Toole (newfoundlander61) found it at a conservation area in Kingston, Ontario, in July 2009.
