I like those! A picture of the bird would be the matching game. I want to add a bird song game too. The idea was to make it like the 20 questions game. Maybe I should lean into this more. I did make something where you guess the species and it narrows down through it's taxonomy.

It's a bad ripoff of the much, much more fun metazooa (https://metazooa.com/play/game). I kike it but it gets real annoying when your down to 1 of 10 bats or something. I've been using it to read and edit Wikipedia articles for undeveloped pages.
