When working on the NYS eBird Hotspots wiki I compare the previous bar chart list of species with the current one to pick up any additions or deletions. By going to each county's 'Overview' page you can find the date the species was added for each county. Some are from newly submitted checklists from several months/years ago where it is not possible on eBird.org 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 wiki click the 'Overview' link on the 'Explore a Location' line: — http://ebirding-nys.wikispaces.com/Birding+in+New+York Yellow highlights a species added for the first time this past year. *Chautauqua County:* Dickcissel (2-Jul-2000) *Delaware County:* Orchard Oriole (15-Jun-1985) *Essex County:* Ross's Goose (25-Dec-2016) Trumpeter Swan (11-Nov-2016) *Franklin County:* Prairie Warbler (15-May-2010) *St. Lawrence County:* Long-billed Dowitcher (5-Oct-2012) Rufous Hummingbird (23-Jul-2015) *Putnam County:* Evening Grosbeak (Removed) -- Ben Cacace Manhattan, NYC Wiki for NYS eBird Hotspots <http://ebirding-nys.wikispaces.com/Birding+in+New+York> Facebook Discussion for NYS eBird Hotspots <https://www.facebook.com/groups/NYeBirdHotspots/> -- NYSbirds-L List Info: http://www.NortheastBirding.com/NYSbirdsWELCOME.htm http://www.NortheastBirding.com/NYSbirdsRULES.htm http://www.NortheastBirding.com/NYSbirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://www.mail-archive.com/nysbirds-l@cornell.edu/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/NYSBirds-L 3) http://birding.aba.org/maillist/NY01 Please submit your observations to eBird: http://ebird.org/content/ebird/ --
