I've just posted the
latest installment of what, when completed, will hopefully be a helpful and
comprehensive article, with photos, on "Cackling Goose - Canada Goose
Subspecies Identification Indicators: The 'Whtie-cheeked Goose' Challenge with
Pictures" dealing with all the currently recognized eleven
subspecies.
This new portion
deals with the difficult parvipes vs. taverneri id problems
(that Bruce Deuel has done some good work on in his upcoming article in Western
Birds, Vol. 35, #3). I also have a previously
completed portion on B. h. hutchinsii as well as a now complete
section on B. h. minima already posted on the site.
Eventually all 11 subspecies will be covered with photo illustrations of
"id indicators". (I think you will find the close-up picture of B.h.
minima, B. h. hutchinsii, and B. c.
parvipes together in the wild at Moses Lake, WA especially
instructive.)
This is a
work in progress, and I do invite comments (and
photos) as you may see fit to help us all better sort out this often thorny id
challenge that has "magically" risen to the forefront since this summer's AOU
"split decision"...while we continue to make everyone more aware of the
wonderful world of the subspecies. I can definitely always use
more close-up pictures of B. h. taverneri, B. h.
leucopareia, and the larger Canada's, B. c. canadensis, B. c.
interior, B. c. maxima, B. c. occidentalis, and B. c.
fulva.
