Subject: [obol] Re: Boiler Bay lawn Aleutians
There was a group of 200+ cackling geese at the ponds along Dawson Creek in
Hillsboro at lunchtime today. A fair number of them, I believe, are
Aleutians, basing this primarily on shape of the bill / face and the white
collar. There was also several that had almost black wings. They had the
bronzy chest of the Aleutians, but no color and very dark wings. I can
post some pictures a little later if so desired.
