I am pretty big on lists. One particular list that I like to keep is a day list, or most birds seen in a day. My personal record occured on May 18, 1996, which I only remember because it was my 17th birthday. Anyway, I did 70 species while I spent the day at Bombay Hook NWR. I may have been at Prime Hook NWR for a little bit, too.
You'll have to do a "Big Day" mid-night to mid-night. You'll get 100 species if you hit a variety of habitats. I did 100+ in so. Ohio in May 1981 twice. Good luck.
Every year in NJ, I believe in May, they do the World Series of Birding, and I know a lot of those groups get well over 100 species. Anyone know anything about this? I'd def. like to partake.
