![]() NPS Photo / Alex Arnold. It's common to spot a snake basking on the monument's walls or a lizard quickly moving around. Both snakes and lizards play a crucial role in the ecosystem, which is why they are protected at Salinas Pueblo Missions National Monument. Lizards are probably the most frequently seen reptiles since they are plentiful and very active during the day. They usually start feeding when the temperature rises above 65˚ F, but when it gets too hot, they retreat to cooler spots and come out again later in the afternoon. Their diets vary; smaller lizards tend to eat insects or plants, while larger spiny lizards can eat both meat and plants. While lizards help keep the insect population in check, snakes also eat insects. Their diet can include rodents, lizards, and rabbits, and they typically swallow their prey whole. Snakes can live in the wild for up to twenty years. Since they can't control their body temperature, they often warm up by sunbathing on rocks or trails. On really hot days, you might find a snake resting in a shaded area, becoming more active as the afternoon cools down. ![]() NPS Photo / Marie Mitchell. Common Reptiles of New Mexico:
