Roger,
I never heard of "leucistic" until we got a titmouse at home with some unusual
white feathers. I sent a picture to Bob Reilly, who is a master bander, and he
said it was a leucistic tufted titmouse, and that he has seen the phenomenon in
many species. I did look it up and seem to remember that the "partial albinism"
was referred to as "leucistic" but I will check it again. Sibley has a yellow
form of house finch listed in his field guide that has a light yellow or orange
color where red normally is found in males. We had one of those earlier in the
year. It is just considered an alternate lighter coloration in that case, not
leucistic.
Thanks,
Al Warfield

Ms. Ealding is correct. Leucism refers to a dilution of plumage, albinism to
purely white feathers, a bird with some white feathers is a partial albino
(According to technical references anyway)

(and it is a good deal less common than partial albinism).

Wendy,
I thought leusistic mean't that some feathers that were normally pigmented are
white. Maybe what you have is really a color variation. Maybe Bob Reilly will
pick this up and have more info on that.

At my feeder today, a Downy that was light brown where it would normally be
black.
