Why is my Quaker parrot sleeping with its leg behind its head?

It is normal for birds to sleep or rest with one leg up. They don't do this all the time though. If she is behaving normally otherwise, she is probably fine. Monitor for decreased appetite or activity, loose droppings or sitting at the bottom of the cage.

Hi, if Sky is otherwise doing well, eating and defecating normally, active and alert, then I wouldn’t be concerned. Some birds sleep with their head tucked under a wing or in some other similar position. Sky’s neck is bent more in the pictures than what is typical for a parakeet, but it could just be normal for him. However, if you notice any changes or if his neck doesn’t straighten out and remains bent when not sleeping, then this would definitely not be normal and should be evaluated by a veterinarian.

It could be that is just how your parrot fell asleep, which can be normal. If he is showing any signs of illness while awake, such as a head tilt then, refusal to eat, listless behavior, etc, then this is cause for concern and should be checked out by a vet.

Many birds, including budgies, will sleep with their heads nestled down over their backs and between their wings, especially at night. This is perfectly normal behavior. However, a bird that isn't feeling well will spend more time with its heads nestled down into its feathers and less time engaging in preening, eating, playing, and other normal activities. A sick bird may also stop vocalizing, sit puffed or fluffed up, sneeze or have discharge from their nares, have loose stools, have stools caked around the vent, and/or pick at its food or not eat at all. So, if your bird seems listless or is exhibiting any of the above symptoms, seek veterinary attention right away.

This is not a typical resting position for birds, though it may be "normal" for Alfred. Monitor for lethargy, loss of appetite or loose droppings. If the behavior persists or if he develops any of these symptoms, then he should be physically examined by your veterinarian or an experienced avian veterinarian.

That is how cockatiels normally sleep. They will also rest on one leg. There is no cause for concern at this positioning. A bird's body temperature is a bit higher than human body temp thus they will always feel warm to us. Monitor for lethargy, sitting with a wide stance and feathers fluffed out, decreased appetite or very loose droppings. These are all symptoms of illness.

This actually sounds like normal behavior when they get tired and start to go to sleep. When they sleep they always stand on one leg and their head is usually tucked into the wing. If he's otherwise eating, drinking and acting like a bird, then I would not worry. I hope that helps.
