Wow, what an amazing database of audio recordings this project has become. As of today, there are almost 4,000 species from 5,690 users uploaded to iNat. @dbeadle with over 500 species is far and away the leader in species and @sandboa with over 1,900 recordings is leading that category by a wide margin. Simply mind-blowing numbers.

The top four species by number of observations are birds and frogs, which I expected, though I wouldn't have been able to guess which species. I'm surprised that #5 is an insect, Silver Princess (Yoyetta celis) with 576 observations. March and April of 2020 have logged over 1,000 unique observers, with March being the first time this occurred.

The only continent without an audio observation is Antarctica. Observations have been uploaded from 150 countries! The United States and western Europe look like a blanket of observations. Some of my favorite observations are the geographical one-offs:
Côte d'Ivoire by @hippolytep38
Djibouti by @saucierj
Ethiopia by @f_morand
Gambia by @curcu34
Georgia by @mkyhnde
Guadeloupe by @valeria89
Guam by @micahfreedman
Iraq by @zayn_alnajm
Kazakhstan by @kastani
Mongolia by @gonodactylus
Oman by @tbrooks
Palau by @sea-kangaroo
Saint Kitts and Nevis by @mlodinow

A huge thank you, not only to the top five in each category (@sandboa, @christie22, @ruslan_mazuryk, @joelp, @rwp84, @dbeadle, @wsweet321, @ntepper, @gyrrlfalcon, @tkoffel), but to everyone who has contributed audio recordings. You are reason that this database has become so fantastic. @kueda and @loarie, did you have any idea what was in store when you added the ability to upload audio files? Thanks for doing so and congratulations on the overwhelming success.
