Camas Prairie Wildlife

The onset of spring finds Camas Prairie Centennial Marsh alive with activity. Warmer temperatures bring snowmelt and runoff water through the area. This abundant water attracts migrating waterfowl and shorebirds by the droves. Waterfowl are most numerous and include species such as Canada geese, mallards, gadwalls, American wigeon, northern pintails, green-winged, blue-winged and cinnamon teal, northern shovelers, lesser scaup, canvasbacks, redheads and ruddy ducks. Mallards, gadwalls, American wigeon, northern pintails, cinnamon teal and lesser scaup all nest on Camas Prairie Centennial Marsh WMA lands.

Shorebirds are also frequent spring visitors and include the majestic sandhill crane, willet, long-billed curlew, American bittern, snowy egret, American avocet, black-necked stilt and Wilson’s phalarope. Sandhill cranes, American avocets and black-necked stilts commonly nest on the WMA.

A pair of golden eagles nest just off WMA property and are often seen soaring high over the marsh. Prairie falcons nest among the lava rock outcrops of the Mount Bennett Hills and forage over all of Camas Prairie. Peregrine falcons hunt waterfowl during spring months, and northern harriers, Swainson’s and rough-legged hawks and American kestrels are common to the WMA. Short-eared and great horned owls also nest and hunt on Camas Prairie Centennial Marsh WMA.

Sage grouse and gray partridge inhabit upland areas of Camas Prairie, occasionally venturing into Centennial Marsh in dry years. Blue grouse utilize Mt. Bennett’s lower foothills and Camas Prairie in the spring, before migrating to high mountain ridges for the summer months.

Songbirds inhabiting the area include most of the western prairie species. The spring abundance of water attracts a few additional species, some of which reside on the WMA throughout the summer. Barn, bank and violet-green swallows hunt insects over Centennial Marsh. Red-winged and yellowheaded blackbirds display and scold from cattail stands, while the shrill call of the secretive marsh wren provides the only evidence of its presence. Upland habitats are home to western flycatchers, horned larks, mountain bluebirds, sage thrashers and a host of other species.

The presence of large mammals often surprises WMA visitors. Mule deer are abundant, utilizing the lush vegetation of Centennial Marsh in the early morning and evening before retreating to the comfort of the surrounding foothills. Small populations of pronghorn antelope patrol the marsh in low water years, grazing and resting. Nearly 500 elk summer in the Soldier Mountains north of the WMA, wintering on the South Fork of the Boise River and occasionally on the Camas Prairie fringe. Moose, first introduced to the Soldier Mountains in 1986, are occasional visitors to the open spaces of Camas Prairie Centennial Marsh WMA.

A number of smaller mammal species range over the WMA, including mink, muskrat, beaver, raccoon, skunk, red fox, coyote and badger. Nuttall’s cottontail rabbits and white-tailed jackrabbits also reside here, feeding on the lush grasses and forbs of the marsh.

Reptiles and amphibians are infrequently seen over most of the WMA. Gopher and common garter snakes inhabit upland areas, while Pacific treefrogs and western toads are locally and seasonally abundant in marsh areas.
