Magnets can keep crocs away from urban areas

Florida wildlife managers have launched an experiment to see if they can keep crocodiles from returning to residential neighborhoods by temporarily taping magnets to their heads to disrupt their "homing" ability.

Researchers at Mexico's Crocodile Museum in Chiapas reported in a biology newsletter they had some success with the method, using it to permanently relocate 20 of the reptiles since 2004.

"We said, 'Hey, we might as well give this a try," Lindsey Hord, the Florida Fish and Wildlife Conservation Commission's crocodile response coordinator, said on Tuesday.
