But new tracking research suggests that for crocs, there's no place like home: 82 percent of displaced crocs returned, from as far as 62 miles (100 kilometers) away. "As soon as you let them go, they seem to turn around and head home," said Perran Ross, a biologist at the Florida Museum of Natural History in Gainesville and coordinator of the Switzerland-based World Conservation Union's crocodile specialist group. Brady Barr, a herpetologist and field specialist, and his colleagues trail and capture some of these "problem crocs," following their tracks to the river. They often pursue these massive, aggressive males at night. From small boats, they shine bright spotlights across the water, searching for the unmistakable golden shine of crocodile eyes. When they locate the culprit, they temporarily blind the animal with the lights while Barr slips a metal snare over its head. | |
