NY County = Manhattan, Marble Hill, Randall's, Roosevelt, Governors & Liberty Islands and some smaller islands.
Below is a list of warbler species reported to eBird for Apr.-May/2017 (30) from rarest to most common based on an algorithm I put together using # of months seen, # of days seen, # of weeks seen throughout the year and the # of checklists it appears based on eBird's histograms. This data is based on all years in the eBird database. There is probably a small bias for rare birds seen and reported by many that I tried to minimize by squaring and cubing the other data. I've done this for the 15 counties highlighted in green or gold on the NYS eBird Hotspots page. I'm using this for studying songs of the most common warblers first and thought it might be a useful/interesting list for others. ... I've added the list of all warblers (39) reported to eBird below this list If you see any major issues with the order let me know and I can look into the algorithm to see what should be tweaked. I'm not a statistician so here's the formula: Avg. of histogram from Bar Charts (*): multipled by # of weeks on histogram squared: multipled by # of individual days reported cubed: multipled by # of individual months reported cubed (*) Understanding the eBird Bar Charts - http://help.ebird.org/customer/portal/articles/1010553-understanding-the-ebird-bar-charts *Warblers reported to New York County* *April through May 2017:* 1.
