I had thought about trying something like Tait's distributional analysis
but it seemed like too much work.
Which it clearly was. Very interesting. Thanks Tait.
But on the subject of 'Cackling' Geese, I had mentioned that the last
(20+/- yrs ago) attempt to supplant
Western Meadowlark was with Dusky Canada Goose, still a true Canada Goose
(B. canadensis occidentalis).
This met with a similar resistance.but it had a certain rationale.
This (current) subspecies has a very narrow range, breeding in the Copper
River Delta area and wintering virtually entirely in Oregon. But with the
current splitomania, who knows?
It was and still is an endangered (sub)species, oddly because it's small
nesting area was greatly disturbed by the Alaska earthquake.
It's a very handsome bird (for a goose that is, reference the g**-d*****
Canada Goose in the dumb-bird field guide.)
In addition to identification by birders, its identification is of real
interest to hunters who have to learn to ID it so that they can limit or
eliminate take of this bird as a conservation move (depending on the yearly
bag limits). Heaven knows we have plenty of the more abundant subspecies.
I haven't seen any Duskies frequenting the MacDonald's environment as yet.
It can be readily observed from roads, often in the original range of the
Western Meadowlark, but still available during winter.
I'm not advocating for it, of course. And certainly, the Osprey, with a
worldwide distribution, doesn't make much sense.
