  • Reptiles of Phil Hardberger Park
    ALAMO AREA MASTER NATURALISTS & PHIL HARDBERGER PARK CONSERVANCY REPTILES OF PHIL HARDBERGER PARK ROSEBELLY LIZARD→ REPTILE= Rosebelly Lizard (picture by author) TERRESTRIAL Fred Wills is the author of this piece. VERTEBRATE Animals with backbones (vertebrates) fall into several classes. We all recognize feathered birds and hairy mammals. But what is a reptile? An easy defini- tion of reptiles is that they are terrestrial, vertebrate animals with scales or plates covering the body. However, this definition simplifies their great diversity. WITH SCALES In Texas alone, there are four major groups of reptiles: lizards, snakes, turtles, and crocodilians (alligators). Hardberger Park is home to lizards, snakes, and turtles. OR PLATES Common lizards of the park include the Rosebelly Lizard, Texas Spiny Lizard, and Ground Skink. Common snakes of the park include the Texas Rat Snake, Rough Earth Snake, and Checkered Garter Snake. Can you name any other lizards and snakes found in the area? Hint: One lizard can change color, and PHP: one snake can produce sound. ROSEBELLY LIZARD Like many birds and mammals, reptiles are predators. Small ones like the Rosebelly Lizard and Rough Earth Snake eat invertebrate animals such as insects. TEXAS SPINY LIZARD Medium-sized snakes such as the Checkered Garter Snake often eat frogs. Larger snakes, including the Texas Rat Snake, typically eat small mammals and GROUND SKINK birds. TEXAS RAT SNAKE Where do reptiles live? The various species occupy almost all kinds of habitats, from dry prairie to moist woodland, and even wetlands and streams. Re- ROUGH EARTH SNAKE lated species often divide up the habitat through differing behaviors.
