The official Florida checklist counts over 500 species, and thus Florida citizens had a wealth of State Bird candidates to choose from when they named the Florida state bird in 1927. This common bird is also the state bird for Arkansas, Texas (another avian hot spot), Tennessee, and Mississippi, so Florida even misses points for originality.

I generally wait until I have at least a dozen species on my year list before having my first drink of the year. But which species of crow is our Old Crow – Fish or American? By my reckoning, 500 miles up the Mississippi River as the steamboat goes only gets you as far as the Mississippi-Louisiana-Arkansas tripoint.

As of mid-October 2018, the Collaborative had submitted more than 1,700 checklists and observed 618 species in the United States. The heat map is revealing: Unsurprisingly for a site founded and run by two New Yorkers (one of whom literally wrote the book on birding New York), the Empire State boasts the highest number of species (316).
