They might catch your eye as they dart under sagebrush. Or maybe startle you with their pushups on a boulder. Odds are, you won’t leave Arches or Canyonlands national parks without seeing a Western Banded Gecko.

These lizards can grow to six inches in length, though that’s on the large side, and half of that length might be their tail. Pale-pink and brown-banded translucent skin distinguishes Western Banded Geckos from all other lizards that live in the same desert surroundings, and their heads and bodies are speckled with light brown. The brown bands are vibrant in young Western Banded Geckos, and then change into blotches, or spots, with age.

The small scales that cover their body are soft to touch, and their slender toes leave no room for pads. Movable eyelids and vertical pupils also set them apart.

The Western Banded Gecko typically are spotted in rocky or sandy desert areas in the American Southwest. They are fond of open, dry deserts, desert grasslands, and catching the sun in the canyons. You can spot them, or one of the eight subspecies, in Glen Canyon National Recreation Area, as well as in Arches and Canyonlands.

Like other geckos, these lizards generally avoid the day heat and prefer the cool night air. They seek shelter during the day near or under rocks, burrows, and spaces beneath vegetative debris, and even trash piles if necessary. They frequent rodent burrows as they hunt insects, spiders, small arthropods, and baby scorpions.

The Western Banded Gecko stalks its prey, capturing and crushing it with its jaws in a final, fatal lunge. The small gecko is one of the few reptiles credited with controlling the scorpion population, by eating their young. The Western Banded Gecko can also mimic a scorpion, by turning its tail upwards, and waving it to repel predators.

In addition to this deception, Western Banded Geckos use other methods to divert predators. Be forewarned: if you plan on catching a Western Banded Gecko, be prepared to hear a squeak or chirp in disagreement. You may even see them detach their tail. Their tail has particular fracture planes, allowing the lizard to easily detach and escape, similar to other lizards. Blood vessels surrounding the tail rapidly close, so they can prevent blood loss. Regrowth of their tails happens quickly, as it is mostly made up of cartilage.

Though the tail serves as an easy escape route, it means a lot to a Western Banded Gecko: that’s where it stores its food and water. Their tail allows these animals to survive during lean times, up to nine months. As you can imagine, losing a tail puts their life in danger, so look but don’t touch.

As with its neighbor, Canyonlands National Park, Arches National Park conceals most of its wildlife from visitors. That said, lizards are easy to spot, as are mule deer in the cool times of the day. And if you spend a little time before breakfast, or after dinner, you just might see coyotes, porcupines, desert cottontails, black-tailed jackrabbits, and many songbirds.

Because of the high heat during the summer months, most of these animals will be most visible when humans are not typically out and about. Desert animals have a variety of adaptations to deal with the hot weather and aridity. A key adaptation is that most animals are nocturnal, being most active at night. Nocturnal animals in Arches include kangaroo rats, woodrats (also called packrats), and other small desert rodents, skunks, ringtails, foxes, bobcats, mountain lions, bats and owls.

Some desert animals are “diurnal”, or primarily active during the day. These include rock squirrels, antelope squirrels, chipmunks, lizards, snakes, hawks, and eagles.

Many animals have are only active in certain temperature ranges, and they alter their active times of day depending upon the season. During winter months, snakes and lizards are in an inactive state of “torpor,” or sluggishness or even dormancy. But they become active during the day during the late spring and early fall, and then become “crepuscular,” or active mainly during the nighttime hours, to avoid the daytime heat of summer.

Insects, too, alter their times of activity. Mosquitoes, as you no doubt know, may be out from dawn through dusk, depending on the temperatures. But they are not active after the sun goes down.

In spite of Arches’ rather inhospitable appearance, almost 50 species of mammals live in the park’s landscape. But the hot climate and lack of water favors small mammals. Because of their size, these animals are less able to migrate, but have an easier time finding shelter, and require less food and water to live. Rodents are numerous: there are eleven species of mice and rats.

Desert bighorn sheep are one of the larger mammal species to be seen. They are frequently spotted along Highway 191 south of the park visitor center, and call Arches home all year long. They roam the talus slopes and side canyons near the Colorado River, forage for plants, and negotiate the steep, rocky terrain with the greatest of ease.

While Arches may not be considered a prime bird watching hot spot, 273 species have been seen in the park, which includes seasonal, year-round residents, and migrants.

Much of this diversity is due to the riparian corridors like Courthouse Wash and the Colorado River (which forms the park’s southern boundary). Mornings along these corridors often are filled with birdsongs during spring and summer. You might spot blue grosbeaks, yellow-breasted chats, and spotted towhees. Listen carefully and you’ll hear the trill of the canyon wren echoing from the sandstone walls. Great blue herons hunt the shallows for fish, while Cooper’s hawks deftly maneuver through the tangle of trees beyond the riverbanks.

There is life in the desert, if you know where, and more importantly, when, to look for it.
