I saw an albino (or maybe pybald, apparently ther's a diff.) about 10 yrs ago that a friend chased for 2 weeks and shot. It was kind of creamy tan where it should be black but had all the outlines of a honker, just way faded out.
That is a park goose.
I have shot park/honker hybrids in the past few years and checked them at the check stations. The guys just laughed. These had white blotches, orange feet and beaks, same color wings as honkers.
My dad whacked two domestic Gray Geese that flew up the valley and landed in a pond in our pasture. He was describing them to me on the phone...Orange feet and beaks, gray on back of wings, brown bodies...they were your run of the mill gray geese, just had a good personal trainer and could fly. Too bad for them my dad saw them fly up the valley
