Fauna of Nevada
The fauna of the U.S. State of Nevada is mostly species adapted to desert, temperature extremes and to lack of moisture. With an average annual rainfall of only about , Nevada is the driest – and has the largest percentage of its total area classified as desert – of all states in the United States.〔Sessions S. Wheeler: "The Nevada Desert" (page 19). The Caxton Printers, 1971. ISBN 9780870042058〕〔http://www.infoplease.com/ipa/A0108242.html〕 Two-thirds of the state is located within the largest desert on the North American continent, the Great Basin Desert, while the lower one-third is the Mojave Desert.〔 The smaller Smoke Creek Desert and Black Rock Desert are located in the northwest, while other deserts include the Yp Desert, Tule Desert, Forty Mile Desert, Owyhee Desert and the Amargosa Desert. Nevada is located within the Nearctic faunistic realm in a region containing an assemblage of species similar to Northern Africa .〔http://www.britannica.com/EBchecked/topic/616563/United-States/77969/Animal-life〕
Animals in Nevada include for instance scorpions, mountain lions, snakes, lizards, spiders, wolves, coyotes, foxes, ground squirrels, rabbits, bats, falcons, ravens, desert tortoise, hawks, eagles, bobcats, sheep, deer, pronghorns, geckos, owls, bats, horned toads and more. Nevada’s rivers and lakes contain large quantities of bass, trout, crappie, and catfish.〔http://www.britannica.com/EBchecked/topic/411016/Nevada/79121/Plant-and-animal-life〕
== Avifauna ==
A total of more than 480 species of birds have been recorded in Nevada, and of these, 300 species have either nested or are estimated to occur with regularity in the state.〔http://www.gbbo.org/pdf/bcp/Birds%20of%20Nevada.pdf〕 The majority of Nevada’s breeding birds are landbirds, but a large percentage of the priority species are shorebirds and waterbirds, reflecting the importance of water bodies in the desert. 78 species of Nevadan birds are currently identified as priority species. These birds are subdivided into 70 Conservation priority species, five Stewardship species, and three Special Status species. The 70 Conservation priority species are identified by the fact that they were ranked as high priorities in one or more bird conservation initiatives. Most Conservation priority species were designated as such by regional initiatives because of population declines, significant threats, dependence on restricted or threatened habitats, or small population size. Three species that were not ranked by regional initiatives (northern goshawk, ferruginous hawk, and golden eagle) were included as Conservation priority species based on current concerns in Nevada and agency priorities.〔
Bird species in the state include the American bald eagles, New World vulture, peregrine falcon, northern goshawk, red-tailed hawk, American white pelican, northern phainopepla, great horned owl, burrowing owl, golden eagle, prairie falcon, greater roadrunner, canyon wren, Gambel's quail, house finch, Harris's hawk, common gallinule, curlew sandpiper, common black-hawk, zone-tailed hawk, red crossbill, northern cardinal, red-faced cormorant, sooty grouse, wild turkey, northern harrier, American bittern, red-shouldered hawk, ferruginous hawk, broad-winged hawk, Cooper’s hawk, elf owl, gyrfalcon, sharp-shinned hawk and many more. The mountain bluebird is the official state bird.
