Tonight I had a flock of geese fly right over my home. At first, I wasn't bothered to record it, but it was quite loud and lasted for so long that I walked up to the window and registered the calls just as they were trailing off. I don't expect a conclusive ID, but I wonder how far one can get without pictures. Both Merlin and BirdNET agreed on Pink-footed Goose, but I'm not holding my breath. I've read that Tundra Bean Goose has a similar call, while Taiga Bean Goose was BirdNET's less likely second most probable suggestion.
