Description

Abstract. -- This study examined the gastrointestinal tracts of 30 museum specimens of Phrynosoma cornutum collected from Chihuahuan Desert habitats in Texas, New Mexico and the Mexican state of Chihuahua. Data collected included percentage of volume and number, mean and frequency of occurrence. Representatives of twelve ant genera were consumed. Pogonomyrmex was the most frequently eaten ant (frequency = 90.0%) and had the greatest total volume and total number of all the items recovered from the gastrointestinal tract. Pogonomyrmex is the preferred prey item of P. cornutum because of its low aggressiveness, high foraging numbers and availability in the horned lizard's habitat. **********
