Where Lizards Live

Something for a Seven-Year-Old

a straight, clear explanation for a 7-year-old:

So, a lizard’s home isn’t a building—

Lizards in the desert have some clever ways of finding homes. They don’t live in houses like people do, but they find spots that keep them safe from the hot sun and from hungry animals. Many lizards dig little burrows in the sand or dirt where it’s cooler. Others hide under rocks, inside cracks, or even in bushes.

During the hottest part of the day, they often stay hidden in these safe spots. When it’s cooler in the morning or evening, they come out to run around, eat bugs, or warm up by lying on sunny rocks.

So, a desert lizard’s “house” could be a hole in the ground, a shady bush, or even a crack in a boulder—it’s wherever they can stay safe and comfortable.

The Mourning Dove Song

Three short, sad notes the Mourning doves call to each other from bunches of thick green leaves in the cottonwood trees. The heat pushes up the canyon, and the bright sun chases the shadows into themselves the way a mirage disappears as you approach.

Boots crunched softly in the thick sand along the trail and spotted lizards dart frantically in the low scrub. The pointed ears of a coyote catch your attention as it leaps over a clump of gray grass to pounce on a squirrel eating a seed. A tortoise marches on steadfastly and fearless in his search for a mate. A cottontail nibbles on a juicy young leaf and listens closely to every scratch and pop.

The late morning finally gives way, and high noon approaches as bold as a bully. The air is clear and hot. The sun burns the back of your hands, bringing salt to your dry lips. Your forehead tingles; you push the brim of your hat back and tilt your head forward a bit to keep your face in the shade.

Grasshopper Mouse

The grasshopper mouse, belonging to the genus Onychomys, is a fascinating creature known for its unique behaviors and adaptations. Here’s a detailed overview of its natural history:

Physical Description

  • Size: Small rodents, typically around 4 to 5 inches in body length, with an additional 1 to 2 inches of tail.
  • Appearance: They have a robust body, short tails, and large ears. Their fur is generally grayish-brown on the back and white on the belly.

Habitat

  • Geographic Range: Found in North America, particularly in the arid and semi-arid regions of the western United States and Mexico.
  • Preferred Environment: Grasshopper mice inhabit deserts, scrublands, and prairies. They are well-adapted to dry environments and can be found in areas with sparse vegetation.

Behavior

  • Nocturnal Lifestyle: These mice are primarily nocturnal, coming out to hunt and forage at night.
  • Territoriality: Grasshopper mice are highly territorial and aggressive. They establish and defend territories vigorously.

Diet

  • Carnivorous Diet: Unlike many other rodents, grasshopper mice are primarily carnivorous. They feed on insects, other small invertebrates, and even small vertebrates.
  • Specialization: They are named for their tendency to prey on grasshoppers, but their diet can also include beetles, scorpions, spiders, and even other mice.
  • Hunting: Known for their hunting prowess, they are sometimes called “scorpion mice” due to their ability to hunt and consume scorpions, showing resistance to the venom.

Vocalizations

  • Unique Calls: Grasshopper mice are known for their high-pitched, wolf-like howls, which they use to communicate with each other, especially to mark territory.

Reproduction

  • Breeding Season: Typically breed from spring through late summer.
  • Litter Size: Females give birth to 2 to 6 young after a gestation period of about 30 days.
  • Parental Care: The young are weaned after a few weeks and reach maturity at around 2 to 3 months.

Adaptations

  • Water Conservation: Adapted to arid environments, grasshopper mice obtain most of their water from the food they eat and have efficient kidneys to conserve water.
  • Venom Resistance: They have developed a resistance to the venom of scorpions, allowing them to prey on these arachnids without harm.

Ecological Role

  • Predator Control: By preying on insects and other small animals, grasshopper mice help control the populations of these species in their habitats.
  • Indicator Species: Their presence and health can be indicators of the ecological balance in their environment.

The grasshopper mouse’s unique dietary habits, vocalizations, and behaviors make it a remarkable example of adaptation to harsh environments, playing a crucial role in the ecosystems they inhabit.
