I’m left wondering what it means to “delete” Mandarin Duck from a list of birds
reported to eBird. I understand that Mandarin Duck is not established in viable
wild populations anywhere in New York State and consequently is not included in
the official list of such species maintained by the New York State Avian
Records Committee. But this species has become naturalized in several places
far from its ancestral range, and it might do so here, at some future time. If
this were ever to become a point of discussion, New York birders would be
interested in tracing where and when the establishment occurred, and the eBird
dataset, focused as it is on the frequency and abundance of bird detections,
would be a natural place to search for evidence.
I would think that reports of species such as Mandarin Duck, Egyptian Goose—and
nowadays, Northern Bobwhite—are worth tracking in eBird, even if they can’t be
regarded as legitimately wild, because future researchers might have good
reasons to want to know where and when people formerly encountered them. One
could argue that even invalidated records are potentially available for future
review, but this isn’t really true, if only because the public invisibility of
“deleted species” would inevitably inhibit normal reporting.

Subject: [nysbirds-l] eBird.org: Recent Additions to County Checklists
When working on the NYS eBird Hotspots wiki I'll compare the previous bar chart
list of species with the current one picking up any additions or deletions. By
going to each county's 'Overview' page you can determine the date the species
was added by county. Some are from newly submitted checklists from many months
/ years ago.
It isn't possible to spot these additions from old checklists. On the
'Overview' page you can sort on 'First Seen' but if the species wasn't added
recently it won't appear at the top of the list.
For each county on the NYS eBird Hotspots site click the 'Overview' link on the
'Explore a Location' line:
Red represents species removed from the New York State list bringing the NYS
total to 479 species.
