A Movable Beast: Asian Pythons Thrive in Florida - New York Times

Skip Snow, a federal biologist in Everglades National Park, would love to spend his days monitoring the dizzying array of native wildlife across this 1.5-million-acre “river of grass” west of the ever-expanding Miami metropolis.

Lately, however, he has been spending ever more time studying the
remains of the park’s birds and animals, extracted from the
stomachs of captured or road-killed Burmese pythons, the latest —
and most spectacular — addition to Florida’s growing list
of biological interlopers.
