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

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.
