Wildlife of the Grand Canyon

Eighty-nine mammal species inhabit Grand Canyon National Park, as well as 355 species of birds, 56 kinds of reptiles and amphibians, and 17 kinds of fish. The rare Kaibab squirrel is found only on the North Rim—you can recognize them by their all-white tails and black undersides. The pink Grand Canyon rattlesnake lives at lower elevations within the canyon. Hawks and ravens are visible year-round. The endangered California condor has been reintroduced to the canyon region. Park rangers give daily talks on the magnificent birds, whose wingspan measures 9 feet. In spring, summer, and fall, mule deer, recognizable by their large ears, and elk are abundant at the South Rim. Don't be fooled by gentle appearances; these guys can be aggressive. It's illegal to feed them, as it’ll disrupt their natural habitats and increase your risk of getting bitten or kicked.

The best times to see wildlife are early in the morning and late in the afternoon. Look for out-of-place shapes and motions, keeping in mind that animals occupy all layers in a natural habitat and not just at your eye level.

More than 1,700 species of plants color the park. The South Rim's Coconino Plateau is fairly flat and covered with stands of piñon and ponderosa pines, junipers, and Gambel's oak trees. On the North Rim's Kaibab Plateau, Douglas fir, spruce, and quaking aspen prevail. In spring you're likely to see asters, sunflowers, and lupine in bloom at both rims.
