Weird Cockatiel Behavior
Hi! I'm new here. I have a six month old female pearl cockatiel. Recently, she has been backing into a corner/sitting by a wall/ my neck (when she's on my shoulder) and fluffing her feathers. She looks very nice and comfortable, but when anyone tries to approach her with their hand she will open her mouth/hiss/nip at you.Sometimes she will start to sway. I don't know if it's a nesting or territorial behavior since she's pretty young. She's usually really sweet and will snuggle up in your arms for a head scritch while your watching TV or sitting on the couch. She's friendly to everyone and has never been aggressive. Anyways, this weird behavior only happens really rarely, but I just want to understand it. This is my first bird and I really hope that some of you can help me out!
