Have you seen a parrot bird sleep like this? Watch this video of the two birds, one is sleeping heavily while the other one tries to wake the other bird up.
The yellow parrot is all wrapped up in a blanket and was sleeping heavily while the other parrot is doing things to get the sleeping bird to wake up like scratching the head through its beak and creating loud noise. It seems like the yellow one doesn’t mind the other parrot because it is still feeling comfy in the blanket. The yellow bird actually does woke a bit but still in the mood for sleeping.
It seems like this bird is feeling a bit under the weather or maybe just having a nice dream.
