What kind of goose is this?

[gorrilla]

I'm not writing this to debate or argue just to say that in one of my former ornithology courses we studied migrating geese with the prof. and he gave a similar example and theory to Tom's as the extra white in the Canadas being a color variation of the same species (like piebald deer) and another common reason being the cross breeding with tame(predominatly white) "park" geese they commonly mingle with, which also explained their common dominant nature we observed.

It makes sense to me that these are the geese you guys are seeing since its obvious most of these geese are the "park" type canadas and not the extremely wild and long migrating tundra grubbers likely to inhabit Quill lakes area and avoid spots like the Twin Cities/Rochester winter staging areas. It seems more likely to me and I have degree(s) in Biology and severly years experience both banding and observing Canadas for MN DNR Wildlife census work. Just my two cents though...

Thought I'd share nuther variety to the discussion. This is one of two wild? migrants that have shown up in the Boise park system for the last several years.
