Screaming is a proclamation of dependence, tid bit almost any hawk for a few days and make it dependent on you for food and it most likely will begin screaming. In pair bonding in wild adult hawks, often one of the adults will declare it is willing to become dependent and announce it by sounding some hunger screams. Signaling a desire to be presented food and signaling a willingness to copulate. IMHO
