Tracking the Tinker Texas horned lizards

TINKER AIR FORCE BASE, Okla. -- JT Parrish, an IT specialist, and Ellen Willse, an aquarist, both with the Oklahoma City Zoo, hunt for Texas horned lizards at Tinker Air Force Base. The Tinker Natural Resources team has long tracked the lizard population on base and has teamed with the zoo, which provides lab space and a place to hatch eggs before releasing the hatchlings back into the wild.
