Learning in nestling begging behavior

What is it about?

The intensity of nestlings begging behavior usually increases with hunger, yet evidence shows that past experience can also affect it. We were interested in how nestlings might be trained to reduce their begging level. In theory, if applying high levels of begging fails to reward them, nestlings may learn to give up and to use lower levels. Alternatively, nestlings may require positive experience of being rewarded for low begging levels before they can learn that such levels are more profitable.
