For one of the education events, the zoo ran a “migration event”. In this event, the kids were asked to pretend to be birds who had to migrate across a continent. There were oases scattered around that birds would stop at to rest, just like in the real world. The kids had to leap from oasis to oasis to get across the field.

The interesting bit was that once the kids did that, disasters effected the environment. A forest fire would take out one. Maybe a nearby city would demolish another. Then the kid-birds would have to migrate back.

This was a way to show, physically, how small human-caused changes can make migration difficult to impossible for some species.
