Missbirders,

This past November I reported four Cackling Geese up at Arkabutla Lake. In
subsequent weeks I saw other geese at the same spot that gave me pause
(short-looking necks, shorter bills, rounder heads, steeper foreheads...),
but ultimately didn't quite register as Cackling Geese. David Sibley
recently posted on his blog about these "Cackling-ish" Canada Geese.

I thought I would share the post here in case others have scrutinized the
similarly puzzling birds.

Also, here is an older post of his giving a more complete treatment of the
Canada/Cackling problem:

Good birding,
