Create groups of five persons.
Give each group the name of a bird.
Each group stands in their own nest in each corner of the play area.
One player is the "hawk", another player is "Mamma Tweet".
Mamma Tweet, from her nest, (one end of the gym) calls out one of the groups by saying their name.
They race toward her nest, trying to escape from the 'hawk".
If tagged, the must sit in the hawk's nest and lay an egg.
Winners can fly away !
