Edit: Current known record is @gwark on July 13, 2018 , with 492 species as iNat counts them!! (511 including non-verifable observation) Here is a table of all the days over 300 species I know of (additions welcome and strongly encouraged!). Observer Date Verifiable Species (as iNat counts the…

last saturday, I broke my record and got 152 verifiable species. I wasn’t actually trying to do a big day, so if I really tried I’m sure I could get more. https://www.inaturalist.org/observations?on=2019-08-10&place_id=any&subview=grid&user_id=alexis_orion

Inspired in large part by this conversation, I got out early last month to do another big day attempt.

As a birder, I am used to Big Day culture, which can be done in teams, competitively, or just individually. I happened in to this previous discussion on the Forum a few days too late to add a comment there, but for reference, here’s that link https://forum.inaturalist.org/t/inaturalist-big-days/528…
