Nearly all the mammals in Florida's Everglades are gone. Scientists think they know who's responsible: a large snake that doesn't belong there. Burmese pythons kept as pets have either escaped or been let loose when they grew too big.
The hunters are out. Our picture, taken in Vermont, shows a store where they go to weigh their kill. The state places limits on what kind of deer may be hunted and when. For example, in Vermont, they may be hunted only between 3 and 11 December of this year.
