In all the discussion about IDing, and the challenges therein, and the various levels of expertise identifiers have, it occurred to me that it might be cool to have a place where people could practice identifying, and finding out some of the tricks, etc. There could be many ways to do this, but I’d see it as a sandbox area, with a (small!) subset of carefully chosen observations and a limited species catalogue, and with explanations around why one ID is correct and another is not. It would need to be fairly constrained - it could easily become a monster! - but it might be one way to help coach people more efficiently than one on one, could be a fun game, and could even eventually be a place for those “here’s how to tell these species apart” guides.
Just a stray thought :-)
