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 additions or deletions. By going to each county's 'Overview' page you can determine the date the species was added for each county.
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 year. *Orleans County: * Harlequin Duck (23-Nov-2016) *Richmond County:* Western Tanager (24-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/ --
