maybe he learned how to play dead
I once seen a video on tv of a dog chasing a duck
the duck stopped and played dead just like that dove did
the dog figured it wasnt fun chasing a dead duck so it left
the duck then got up and walked away LOL
My son has put Skye on his back, on his hand or in his cubby, and he will lay there like he is dead and won't even move.
He was able to hold him this way because the Skye trusts us and has no fear, and he would stay upside down for a long time, IF I didn't interfere but I made him quit doing it, as I feared it would cause him harm.
I did this with one of my pet pigeons as a child,.... even the ants began to walk on him.
I don't recommend or advise any one try this at all AND especially if the bird has just eaten and has any food/water in the crop. PLEASE, just wanted to share.
