on the advice of a mercer island tweeter a few months ago, my friends and i
were able to locate and photograph a leucistic robin (perhaps less than 5%
short of full albinism) in a local park... apparently, he hides
(intelligently) deep in "the junk", and yet the entire park population knows
him... he's been there a few years now...

Devorah,

A all white robin was seen and photographed during the CBC near Detroit Lake
in Oregon two years ago.
