I hate that I know this stuff, but the ABA rules are (highlight added by
me):
"an individual of an introduced species may be counted only *when part of,
or straying from*, a population that meets the first seven criteria of the
ABA Checklist Committee’s Criteria for Determining Establishment of Exotics
<https://www.aba.org/criteria-for-determining-establishment-of-exotics/>"
The Swinhoe's White-eye population in Southern California meets this
criterion. The impossible question to answer is whether a bird seen in San
Francisco is "straying from" the Southern California population, or is it
an independent escaped bird? If you think it isn't a stray from southern
CA, how close do you have to be to Santa Barbara (the seeming northern end
of its range) to be countable? eBird treats Morro Bay records as countable,
San Jose (and further north) as not. I suspect this was not an
evidence-based decision.
Deferring to eBird is reasonable, making up your own mind is allowed.
