Hi everybody, Last night I woke up with a weird question (maybe at 4 am) and the strange fact is that I remember it till now. My question is : say you see a bird borning and the bird only knows you and noone else nor even listen to a single other bird in its life. Can you teach it to whistle a bit differently that it would whistle if it was born between other birds? For example if the bird species whistle like " iiii iiii, iiii iiii", is it possible to change it for "iiii iiii iiii, iiii iiii iiii"? I guess it depends of the specy. So is that possible to change the "instinct" or maybe it's not an instinct but an asset property, of any bird? Because I know that some birds can just imitate sounds and they can learn easily, but other's don't seems to have this facility of learning. Just curious about it.
