A pet bird yawns to stretch its facial muscles and when they are tired.
Yawn: (verb) Pet birds do yawn. They yawn when they are tired or to stretch facial muscles; however if that yawn is really your pet stretching out its neck and gasping for air – which can look a little like yawning – then it is having respiratory distress and should be taken to an avian vet immediately.
