Hi Bob,

Thanks for the thought.  I didn't get a good enough look to really 
explore the options.  I would have, if the group had stayed in place.

My starting point was the heft of the bird, so noticeably larger in 
appearance than the Canadas it was with, which were small Canadas if the 
Snow Goose was a normal size.  That sent my brain to a domestic goose of 
some sort, but I couldn't make that hold up later with a cursory on-line 
search.

I've seen all sorts of leucistic birds with varying degrees and 
distributions of white.  That may not have jumped into my mind because I 
perceived the bird to be more stocky than a Canada Goose.  I haven't 
forgot about other species being hybridized as well.

I'll try to find it again tomorrow.  Where first seen it was only 
300-400 feet away.  Where it went was 4000 feet distant, and there was a 
lot of heat distortion in the cold air over the warm ground of the last 
few days.  If I do refind it, I'm curious to see if my quick 
observations in that limited time hold up during a more sustained and 
comprehensive view.

Best regards,

Ian
