Hi there! Welcome to Pet Talk.

Your cockatiel seems to be picking on his feathers. Have you seen him do that? Feather picking can be a problem in some birds, and there could be a number of causes. Some birds pick on their feathers out of boredom. Some just don't know how to preen properly and rip their feathers in the process. Sometimes an illness can cause frustration that can lead a cockatiel to picking its feathers. Sometimes mites can cause a bird to itch, and that too, can lead to picking feathers. Its best to get him checked by an avian vet to rule out any illness. Hope your birdie's feathers grow back soft and beautiful soon. He isn't too bad...my friend's bird's feathers look a lot worse...and she did take him to the vet. He's doing it out of boredom, and sadly, it can be difficult to stop...but you'll need to discourage it. It can develop into a major problem. Good luck!

Ps. CUTE tiel!
