Apart from it being extremely adorable though, Andrew, what else does it tell us?
Andrew GallupGUEST
I mean, in the budgies, we did experiments where we had the budgies in a cage and they were paired together and there was a barrier between them.
Andrew GallupGUEST

Andrew GallupGUEST
But when the barrier was removed and they had visual access to one another, their yawns were significantly clustered together.
