"Unpublished work shows their yawns are more contagious after a sudden loud noise, suggesting yawning might help coordinate group alertness in the face of a threat."

Yawning is their response to danger? Cool birds

Many animals yawn, but only humans and a few other primates are known to trigger cascades of yawns around a group.

Is this likely to be an example of convergent evolution? Or just that it has only been observed in primates and now budgerigars, and is a behaviour that occurs in other birds and mammals, inherited from a (reptile) common ancestor?

Do they put a wing over their beak when they yawn? :-)

My budgies yawned sometimes too, but they were very tame and when one of them yawned while standing on my hand, it seemed his way of telling me he felt unthreatened, perhaps also signaling the other bird that it was safe to approach as well.

Of course I could easily be anthropomorphizing, but it seemed to me that the yawn had some of the same function as it did with humans, signaling "yeah, whatever."
