Right! Do you know how well the problem of multiple overlapping vovalizations has been solved? But anywway yes it's fantastic, and really cool that the models (Bird Packs to download on a phone) are becoming available for many more places around the world. I had been wanting to try it on South American birds for years and finally got the chance this year in southeastern Brazil and it was especially amazing in a place where I can place way fewer of the vocalizations.
