I know of 4 ideas...

- WAIR (attempted trunk-climbing).
- FUCHSIA (attempted swimming).
- Trying to regain equilibrium.
- Repeated trials to grab the next branch.
- Repeated trials to grab some prey (insects).

Needless to say, all evidence here is negative and very circumstantial. The
last idea has (speculatively) been proposed for bats. The 3rd looks least
likely to me, but what do I know.
