When I work on the NYS eBird Hotspots wiki I'll compare the previous bar chart list of species with the current one to pick up any new additions and/or deletions. By going to each county's '*Overview*' page I can determine the date the species was added for each county. Some are from newly submitted checklists from several years ago.
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 species added for the first time this year. *Herkimer County:* Barnacle Goose (24-Oct-2016) *Madison County:* Hudsonian Godwit (26-Oct-2016) *Rockland County:* Lapland Longspur (27-Oct-2016) *Westchester County:* Virginia's Warbler (1-Nov-2016) -- 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 http://www.NortheastBirding.com/NYSbirdsRULES 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://birdingonthe.net/mailinglists/NYSB.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
