Subject: [Arlington Birds] Cackling Goose - Clay Pit Pond, Belmont
This afternoon I was able to locate a Cackling Goose in Clay Pit Pond in
Belmont, which is located along Concord Avenue in front of Belmont High
School. The bird was sometimes on its own and at other times associating
with Canada Geese. I was first able to pick the bird out from a distance
by its small size relative to the other geese present. The ebird report
will include a couple poor iphone photos, which give a sense of the
relative size. I think this is the Richardson's subspecies based on photos
I review on the web but I'm interested to hear others opinions.

Cackling Goose 1 Picked out from other nearby geese based on size.
Neck half as long as nearby Canadas and from the rear overall body mass
about one third less. Bill noticeably smaller and forehead more sharply
angled. Feathers on mantle lacked scalloping seen on Canadas. Overall the
mantle was a more even brown color down to waterline. In good light could
see a couple white feathers at base of neck but no white ring noted. After
reviewing pictures on the web suspect this is a Richardson's Cackling Goose.
Canada Goose 75
Hooded Merganser 3
Double-crested Cormorant 15
