Evan, other e-bird folks,
Personally, I see no reason why a person can not list on e-bird what are
considered "escapees" or other species that likely didn't arrive at a location
on their own (OK, we can exclude those Graylag Geese at the Farmers place).
Last year I listed a drake Mandarin Duck, which may have been an escapee,
however, about 300 or so mile south of Grants Pass, in Sonoma Co, CA, there's a
breeding population of this species. The bird seen could have been fledged
from down that way and arrived in the Rogue Valley on the strong south winds
blowing at the time it was found.
As you mention, bird populations are dynamic and do change over time.

My assumption up to now has been that eBird checklists should include
escapees, as this data is still scientifically useful (potentially very useful
in the occasional instances where a species later becomes established). The
only things I omit from my lists domestics which are clearly associated with a
specific location where they're actively being taken care of by humans.
However, I've never seen any actual guidelines from eBird on this issue. Has
anyone else?

I meant the original email for people who might "chase" without knowing. I
enjoy the peafowl at Mildred Kanipe Park, but I don't "list" them, nor post
them to obol or ebird them any more than I would something at a Zoo. No
disrespect against the bird itself intended.

Sure - enjoy a very attractive bird. I agree that this bird has to be an
escapee. It is not a species that could reasonably be expected to occur here
as a vagrant.

Even an escapee, in my opinion as a birder, is definitely worth a look!
Thanks for sharing!
