Apparently, four cackling geese have taken up residence with a flock of Canada Geese that hang out on the practice fields at Monte Vista and on the pond at the adjacent Oak Hill Park. I've seen them pretty much every day since I reported them earlier in the week. They were on the fields at 7:30 this morning.
Love the cackling as they fly--quite distinct from the honking of the geese. Again, not sure of the subspecies, but one has a much thicker collar and appears slightly lighter and larger than the other three.
