Bird help!

This bird landed on my feeder today. It sat with a male house finch so I think it is a female but it is mostly white. Has anyone seen a similar bird? Does anyone know what this bird really is?


Albino House Finch?

update: With a little help from Muskegon County Nature Club Homepage, a member sent me this.
"We're 99% sure the bird is a house finch, and we'd call it "leucistic" rather than "albino" since the bird does have some color (but we're no experts)."
Thanks!
