The Sonoran Desert is home to a wide variety of animals, birds and other creatures. Mammals include large animals like the javelina, coyote, Mexican Wolf, bighorn sheep, and bobcat. Smaller animals like the fox, skunk, cottontail, and jackrabbit also live here.

Another mammal that lives in the desert is the bat. These animals pollinate many plants and eat lots of bugs. There are two bats unique to the Sonoran desert: the long-tongued bat and the long-nosed bat .

Even rodents like the packrat, round-tailed ground squirrel, and mice make the Sonoran Desert their home. Many of these animals are nocturnal. By hunting and foraging for food at night, they keep cooler and are less likely to become dehydrated.

Did You Know?
Burrowing owls are unique among birds because they nest underground in existing ground squirrel, coyote, and badger burrows. They are also commonly associated with humans and will frequently nest in burrows along irrigation ditches, canals, and even in people’s yards.
