He had some blueberries for breakfast; you can see he left some on his lower beak. This is Merlin’s standard “scratch my head” pose. He puffs up and shows me exactly where he wants me to rub. If I take too long, sometimes he sticks his toenail up his nostril or in his ear.
He’s such a goober-belly. That’s a term only used by us experienced parrot people, by the way.
