Hummingbirds are fast and hardly stand still, a fact that protects them from many a predator. Unfortunately for them, however, not from the praying mantis, which is a study in patience. We've found one that's waited 24 hours by a bird feeder before zeroing in on the unlucky hummer that came too close. One snatch, and the bird is no more, dangling upside down, waiting to be devoured by the hungry mantis which will eat for a while.
