Horned lizards are sometimes called "horny toads" but they are not really toads.

Of the lizards, Whiptailed and Fence are the most commonly seen in the park. Collared lizards and Horned lizards are plentiful but more common on the dry, rocky mesatops than in the canyons. All are most likely seen sunning themselves on a rock, tree trunk, or pueblo wall when the temperatures are warm but not hot. Favorite food for all lizards is insects.
