Oasis Valley Birding Hotspot

Located in Nye County conveniently situated along Highway 95, two hours north of Las Vegas, Oasis Valley stretches several miles upriver from the town of Beatty, the "Gateway to Death Valley." Several spots are accessible to birders and nature lovers.

Torrance Ranch Preserve is a great place to look for Oasis Valley birds. This Mojave Desert valley along the Amargosa River hosts many diverse habitats: cottonwood and willow groves, marshes, grasslands, and desert upland scrub. The river usually runs underground except after storms, yet the valley is lush with many springs, some bubbling out of the ground at 100 degrees Fahrenheit, creating a true oasis amid the arid rhyolitic hills.

Any time of year can produce interesting bird sightings: summer warmth brings Western kingbirds, the occasional Vermillion flycatcher, abundant Lesser nighthawks, and singing Yellow warblers, Blue grosbeaks, and Bullock's orioles. Winter rains fill river pools and ponds that attract ducks and sandpipers, and upland birds during this time include Northern flickers, Ruby-crowned kinglets, Water pipits, Mountain bluebirds, and White-crowned sparrows.

But the wetland and riparian habitats create "migrant traps" during spring and fall, the best times to visit the area. Waves of warblers, vireos, flycatchers, tanagers, hummingbirds, and other migrating birds travel through, resting and feeding in the thickets and trees.

Public Access

Many parts of Oasis Valley are private ranches or holdings, and permission must be sought to enter. But fortunately areas are open to the public.

Torrance Ranch Preserve is run by The Nature Conservancy, and is located about 7 miles north of Beatty along Highway 95, on the east side. Go north past Boiling Pot Road just a bit, and the next dirt road on your right is the access to the preserve. You will see a sign. Please close the gate when you enter to park in the small staging area (feral burros roam the valley and will get in), then head for the trees to look for songbirds and owls, or the spring-fed marshes to listen for rails. Follow trails and a boardwalk.

Amargosa Narrows

Another prime birding area is at the "Amargosa Narrows" just south of town. Head a mile south on Highway 95 from the stop sign, and turn left on a dirt road that crosses a cattle guard and the river (usually dry). This road heads up into the Bare Mountains, but you can park by the cottonwood and mesquite riparian woodland and walk along the dense thickets either way. In spring, Yellow-breasted chats, Black-headed grosbeaks, and occasional Bell's vireos sing noisily here. You can drive up into the Bare Mountains to bird the creosote hills for Loggerhead shrikes, Roadrunners, and the secretive LeConte's thrasher.

A tenth of a mile to the south of this stop along Highway 95, try looking for waterbirds at "Pombo's Pond" behind rows of tamarisks along Vanderbilt Road on the right.

Habitats

Cottonwood and Willow Riparian Groves

Oasis Valley and the Amargosa River have rare groves of trees in the Mojave Desert, requiring well-watered soils. These are hotspots for migrating birds and nesting species. The diversity is high, with warblers, vireos, flycatchers, woodpeckers, owls, and many others.

Mesquite

Thickets and small bosques of honey mesquite and screwbean mesquite grow along the Amargosa River corridor. These harbor many migrants and breeders, such as verdins, warblers, gnatcatchers, and the rare Bell's vireo.

Mojave Desert Uplands

The Oasis Valley and Beatty are surrounded by Mojave Desert scrub with a rich variety of shrubs such as Creosote (Larrea tridentata), Bursage (Ambrosia dumosa), Nevada Mormon tea (Ephedra nevadensis), Fremont pepperbush (Lepidium fremontii), Wolfberry (Lycium andersonii), and Budsage (Artemisia spinescens)--home to Black-throated sparrows, Sage sparrows, Horned larks, and Prairie falcons. After wet winters some years have spectacular wildflower displays.

River Pools and Saltgrass Meadows

Transition Shrublands

Areas of saltbrush, rabbitbrush, greasewood, cheesebush, and other shrubs around the edges of Oasis Valley, in washes, fans, and on disturbed ground. They often lie between marshes and desert uplands.

Freshwater Marsh

Summer-green ribbons of springfed marsh fill areas of the valley, composed of Threesquare bulrushes (Schoenoplectus pungens), sedges (Eleocharis spp.), rushes (Juncus mexicanus), cattails (Typha spp.), and other plants. Here you can see blackbirds, marsh wrens, rails, son sparrows, and other marsh birds.

Lush new bulrush marshes emerge after a controlled burn on Torrance Ranch Preserve. Marsh vegetation is very well adapted to fire, and in the past lightning strikes lit occasional blazes, and Shoshone and Paiute people set fires to improve hunting areas and manage basketry plants.

Amargosa River

The Amargosa River flowing after a winter storm. Dabbling ducks such as Mallards can often be found in these shallow waters, as well as migratory sandpipers.

California and ring-billed gulls are occasional visitors to the area, but seldom stay long as they travel to large interior lakes and the pacific Coast.

Meadows and Grasslands

Grasslands of native Nevada bluegrass (Poa secunda ssp. juncifolia) with tall stems dried like hay in late summer. These areas are often shallowly flooded in winter. Meadowlarks and Savannah sparrows favor such habitats. Northern harriers forage over these areas, nesting in taller marsh vegetation. Kestrels hunt grasshoppers, and nighthawks catch insects in summer over these habitats.

Ranches, Yards, Buildings, Weed Fields

These edge habitats and built environments host a different set of birds, many often adapted to disturbed areas. Ask permission before you enter private property; many locals are often interested in birding.

Mourning doves are a common summer resident.

Migrants

Many birds migrate through Beatty and Oasis Valley in spring and fall taking advantage of the water and varied habitats. Other birds irregularly wander through the area.

Rare Birds

The acute observer will sometimes notice unusual birds visiting the area, well outside of their normal ranges, often seen only once in a decade or more (such as this male bronzed cowbird, left). This can make for fun birdwatching, and can attrract birders from outside of the area. Here are a few seen in Oasis Valley over the years.
