Hello,

so as you know, i have a new Cockatiel Max for about a week already. He is adjusting really well. Eating, drinking. He displays signs of being comfortable by grinding his beak and lifting one foot up and hiding it inside his floof. He also seems to have claimed his cage as his territory as when he sees some pigeons outside he spreads his wings widely and starts to sing shortly after.

However today i have noticed a tiny bald spot just at the joint of his wing. It's kinda hard to see as it's covered by other feathers.
Here is a pic:



He does preen quite often, but not all the time. Should i be concerned about it?
