I rescued a starling and hes about six weeks old, he is just starting to self feed, flys, hes very freindly and bonded to me, he flys to me but he has started to get nippy. He doesnt hurt me but he gets very excited when i let him out, he flies to me and squawks and nips until he calms down. He loves to play with tissues and paper and hide in the crease of my arm. How long does this nippy behavior last? it worries me as he has poked me in the face sometimes and i get nervous around my eyes.
