Tweeters,
Thanks to Jeff Deam for great photos of yesterday's bird. I received an
email from Bill Anderson rightly stating that the term leucistic would
be correct for plumages like the duck in the photos. This would be where
birds have white feathers like an albino but normally pigmented eyes.
For those interested in the differences and some cases that might not be
so straightforward, it might be worthwhile to check out

All the best
