Question. This also happens in the wild right? Not the apps. But same species make the same noises, sing the same songs. So lets say I'm a bearded reedling and I'm having a wife and a nest. But then a fellow bearded reedling passes by on my territory. It makes the same noises as I do, and it sings the same song as I do. This is a perfectly natural happening, because there are lots and lots of bearded reedlings. Of course I try to make him go away, it's my territory! Heck yeah.
So my question is, what's the big deal? Why can't we use bird sounds? If I don't do it, maybe an other bird will do it. Isn't that kind of the same thing? Except from the fact that I'm not really a bird? If I and my app harm a breeding bird, than so will a random bird from the same species do. But that happens all the time, so is there really harm in using apps?
