Bay-breasted Warbler - Magee Marsh - Lucas County OH - 2013-05-05. Photo by Greg Miller. Nearly 1 out of every 5 sightings of this species in North America in May 2013 was recorded in NW Ohio (18.9%). eBird as of 11/29/2013.
Each year, birders from across the U.S. and around the World come to northwest Ohio to go birding. Spring in particular is a great time when visitors come by the tens of thousands and spend millions of dollars in the area. I do not have the exact numbers, but I am sure others do.
