  1. Yosemite Wildlife Nickolas Littau

  2. Black Bears • Called Black Bears, but they’re often not black • Can be brown, blonde, and even white • Mainly vegetarian diet of grasses, herbs, berries, and nuts • Some non-vegetarian sources include ants, termites, and bees • They don’t usually eat, meat, but will if other food sources are low • Yosemite contains about 300 to 500 black bears

  3. Mule Deer • One of the most common animals in Yosemite • Have large ears and an overall large size • Antler growth begins in the spring, and grow to full size in the summer • Eat a variety of vegetation, including leaves, beans, shrubs, and grasses

  4. Sierra Nevada Red Fox • Endangered species • One of the most endangered in North America • Slightly smaller and darker than other red foxes • Not much is known of the life of the Sierra Nevada Red Fox, as sightings are very uncommon • Live at about 6000 feet elevation • Live in rock outcrops, logs, and burrows in soil

  5. Great Gray Owl • Endangered species • Largest North American owl • Can also be found in Europe and Asia • About two feet tall • 5 foot wingspan • Distinctive bright yellow eyes • Yosemite holds 65% of California’s Great Gray Owls

  6. Sierra Nevada Bighorn Sheep • State and federally endangered • Only species in Yosemite endangered under the federal Endangered Species Act • About 3 feet tall • 140 – 220 pounds • Females have small narrow horns while males have larger ones • Eat grasses located on open plateaus and meadows • Color can be anywhere from white to dark brown

  7. Mountain Lion • Black-tipped eats and tail • About 130-150 pounds (less for females) • Hunt small mammals at night for food • Adults can be over 8 feet long • Mountain Lions cannot roar but can create a loud scream • Will often eat Sierra Nevada bighorn sheep, which are federally endangered

  8. Bats • Yosemite contains 17 species of bats • Most common is the Big brown bat • Largest bat is the Western mastiff bat (also the largest bat in North America) • Smallest bat is the Western pipistrelle • During the day, Yosemite’s bats enter a sleep state, letting their body temperature drop • Have an average lifespan of 34 years

  9. Rattlesnake • Brownish-gray in color • Triangular head, narrow neck, and vertical pupils • 2-4 feet long • Mainly feeds on ground squirrels • Lives under rocks, locks, and woodpiles • Rarely rattle, even in the presence of predators • Flick their tongues to obtain scent information

  10. Alpine Butterfly • Usually live above 10,000 feet in elevation • Average lifespan is two to four weeks • Population is declining at Sierra Nevada sites • Many butterflies in Yosemite choose to fly at such a high elevation because alpine plants are used as food and egg-laying sites • Climate change is affecting plants, which is then affecting many species of butterflies

  11. Summary • Yosemite is the home to over 400 species of vertebrates • Many of these species are endangered, some critically • Climate change, deforestation, and uncontrolled wildfires destroy the animals’ habitats • While Yosemite National Park is an extremely diverse ecosystem, we need to work to keep it that way.
