Ostriches’ contagious yawning!

0

It is known that all vertebrate animals yawn. The cause of yawning is not fully understood, but it is surely contagious. Ostriches are known to yawn as soon as they are hatched. Yawning happens mostly before sleep. At night, when ostriches are ready to settle down, they yawn in groups. First, the leader yawns, followed by the rest of the group. This is the way the leader communicates to the flock to all settle down.
