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.
