For Canada Goose aficionados, I've posted pics from Kiwanis Park, Carter Lake, (just barely in Iowa) of what I believe is a migrant flock derived from the well-documented hybrid zone between hutchinsii Cacklers and interior Canadas along the west shore of Hudson Bay, where our eastern Nebraska hutchies and presumed interiors come from. I'm very interested in comments. I found several birds in the flock that I think are intergrades, but probably 80% at least looked like interiors. I'd really appreciate comments! I may be completely wrong, and if so I want to know!
