The safety and dominance comments sound right on the money to me! Our QP displays similar behavior (he is also flighted - soon to be clipped). He flies over and often lands on my head and preens me. There some slight differences though. For one, he'll normally let my pick him up off of my head or shoulder. Also, after being gentle for a time, he'll start yanking at my hair really hard and pecking at my head like a woodpecker. Can we say dominance attempt? Lately, he's landed on my finger several times

, and also has been landing on my shoulder some

. We don't allow him on our shoulders because when he was younger he bit the **** out of my neck multiple times. It seems that "Love of All Pets" and I are in the same boat.
