Came here for this. My wife is a big Merlin fan, but I'm pretty hard of hearing and much more visually-orientated when it comes to the natural world. INat is a fantastic project, I've learned so much through it.

And for birdsong there is specifically BirdNET, operating on a similar principle as this.

I might check out Merlin specifically just for the ID wizard, for raptors which are pain to photograph and are best IDd by shilouette.

Interesting to note that Merlin and BirdNET are both through Cornell Labs...
