Florida - Thursday February 24, 2023: The U.S. Geological Survey has released a study on the Burmese Python that presents new data on body size, diet and geographic distribution in Florida of this invasive species.

Burmese pythons were confirmed to have an established breeding population in Everglades National Park in 2000. The population has since expanded and now occupies much of southern Florida. They consume a wide range of animals and have altered the food web and ecosystems across the Greater Everglades.

The study pulls together the expertise of scientists and managers nationwide and provides a breakdown of 76 prey species found in python digestive tracts. Their prey primarily includes mammals and birds, as well as two reptile species, the American alligator and the Green iguana. However, as the study notes, the variety of prey is likley to increase as the python population continues to expand north.
