There's Merlin and then there's Birdnet too https://birdnet.cornell.edu/. Both by Cornell.
I've been using birdnet, but it seems to want an internet connection to do the identification and sometimes that is dicey when there is a bird that I want to identify. (Also birds seem to shut up around the time you get the app open.)
I'm going to give Merlin a try - the app has UI to download the network for offline use.
Requiring an internet connection for a nature app is absurd. As annoying as it is I get why a big tech company like Google fails at this sort of thing, many of their employees probably never leave a city and so the products always work well for them. But a nature app has no excuse, normal usage will get blocked by that all the time.
