You know what, I've just checked and birdNET app is the one I use in the field, I thought I was using something from eBird. BirdNET is great for UK birds, I use it all the time! I'm an ecologist doing bird-stuff

Was going to suggest this - I've not used it myself but friends have and the model apparently does have fairly good results https://github.com/kahst/BirdNET-Analyzer
