Lizards and Skinks
Types of Lizards and Skinks
Northern alligator lizard
This lizard prefers humid areas, such as the edges of meadows in coniferous forests, and is also found in riparian zones. This is the only lizard found in the cool coastal forests of northern Oregon.
The Northern alligator lizard eats small invertebrates (termites, beetles, ticks, spiders, millipedes, and snails), and occasionally takes small birds, mammals, and other lizards.

Southern alligator lizard
The Southern alligator lizard is found in a variety of habitats from grassland and chaparral to oak woodlands and edges of open coniferous forests, as well as riparian zones and moist canyon bottoms. It requires thickets, brush heaps, downed logs, or rock piles for cover.
This carnivorous lizard feeds primarily on small invertebrates (slugs, spiders, centipedes, scorpions, beetles, grasshoppers, and crickets), but also is known to feed on bird eggs, nestlings, other lizards, and small mammals.

Mojave black-collared lizard
This lizard is found in a variety of desert shrub vegetation types, but is most dependent on the presence of rock outcrops, boulders, or talus slopes.
The Mojave black-collared lizard is an aggressive carnivore that eats a variety of other reptiles and large insects, such as crickets and grasshoppers, as well as some plant material.

Long-nosed leopard lizard
These lizards are found in open desert shrublands, particularly where islands of sand have accumulated around shrubs and are absent where a dense grass understory would inhibit their ability to run.
The Long-nosed leopard lizard eats large insects, such as grasshoppers, crickets, and beetles, and also takes small vertebrates, including pocket mice, side-blotched lizards, whiptails, and Western fence lizards. Some plant material (flowers, berries) is eaten when available.

Pygmy short-horned lizard
The pygmy short-horned lizard occurs in sagebrush deserts, juniper woodlands, and open coniferous forests. It prefers open areas with sandy soils, but is also found on rocky soil.
Ants make up a large part of the diet, but beetles, caterpillars, spiders, and sowbugs are also eaten. This lizard burrows into the soil when inactive.

Desert horned lizard
The desert horned lizard is found in flat or gently rolling deserts covered with sagebrush or salt-desert shrub. It prefers areas with scattered bushes and loose, sandy soil, but sometimes occurs in rocky areas or on hardpan.
Primary foods are ants and beetles. It also feeds on insect larvae, spiders, crickets, flies, and small grasshoppers.

As their common name implies, these lizards are found in sagebrush habitats, but also occur in chaparral, juniper woodlands, and coniferous forests. They require well-illuminated open ground near cover and are primarily ground dwellers.
They eat a variety of small invertebrates, including crickets, beetles, flies, ants, wasps, bees, mites, ticks, and spiders.
Also called the Northern sagebrush lizard, it is an Oregon Conservation Strategy Species in the Columbia Plateau ecoregion.

Western fence lizard
The Western fence lizard occupies a wide range of habitats, from desert canyons and grasslands to coniferous forests. It requires vertical structure in its habitat, such as rock piles or logs. It is absent from dense, humid forests and flat desert valleys.
This lizard is insectivorous, and feeds on crickets, grasshoppers, beetles, ants , wasps, leafhoppers, and aphids. Some spiders are taken as well.

The side-blotched lizard is found in sagebrush, juniper, and shadscale habitats. It is often found on sandy bottoms of washes or canyons, especially in the presence of scattered rocks.
This small lizard feeds mostly on smaller invertebrates such as spiders, mites, ticks, sowbugs, beetles, flies, ants, and small grasshoppers.

The Western skink is found in moist places such as under rocks or logs in a variety of habitats from grassland and chaparral to desert scrub, juniper woodlands, and coniferous woodlands and forests. Rocky areas with some moisture, such as riparian zones, are favored.
This skink feeds on a wide variety of invertebrates, including beetles, grasshoppers, moths, flies, spiders, and earthworms.

The Western whiptail is found in eastern Oregon deserts and semi-arid shrublands. It is most common in flat, sandy areas and along dry washes.
These lizards are primarily insectivorous. In a food habits study in southeastern Oregon, they ate caterpillars, crickets, grasshoppers, and beetles. They also eat spiders, scorpions, and other lizards.

Plateau striped whiptail
The plateau striped whiptail is a medium-sized, all-female species. Reproduction is by parthenogenesis - unfertilized eggs hatch into clones of the mother.
In Oregon, this lizard only lives in Cove Palisades State Park.
