Laps
Originally, the term comes Lahnen from Falkner language and meant the violent food-begging for the Falkner returning Beizvögel .
In modern ornithology, leaning is understood to mean both the young birds' begging for food towards their parents and the ritualized begging for food of the female ready to mate towards the male.
