KILLDEER

    Predators: Snakes, foxes, coyotes, ravens, hawks and eagles.

MAMMALS
COYOTE

    Predators: Humans, mountain lions.

WHITE-TAILED ANTELOPE SQUIRREL

    Where do they live? Southern California and southern Nevada (Mojave Desert), in shrubland, desert washes, and riparian areas.

    In which plant communities? Joshua tree, pinyon-juniper, desert scrub, alkali desert scrub.

    Food Sources: Seeds, fruits, and green vegetation from Joshua trees (seeds), Mormon tea, western honey mesquite (beans), cat-claw acacia, prickly pear cactus, blackbrush, native grasses, and others!

    Predators:

REPTILES & AMPHIBIANS
CHUCKWALLA

    Food Sources: Mostly insects and lizads, and sometimes flowerbuds, flowers, leaves and berries.

DESERT TORTOISE

(C) Berry and Duck 2006, http://deserttortoise.org

    Habits: Emerges in spring to forage for wildflowers and other annuals, hibernates in an underground burrow from October until early spring (February). Drinks water from small pools after rainstorms, in dry times they obtain moisture from their food.
