How cute can tiels possibly be while preening?!

Cookie has a different style!

I think the cut looking bits are just from them rubbing their tails against stuff and damaging them a little.

My two preen there tails like bailiee lol

I think that makes them normal. I can't say i've seen any bird use the "over head" method Cookie was trying out. LOL!
