By June all birds that will nest at Benton Lake have arrived. With adequate runoff and/or artificial flooding, broods of ducklings, colonial nesting birds like eared grebes, white-faced ibis, and Franklin's gulls can be seen. As water receeds, a variety of shorebirds can be seen including, yellow legs, avocets, willets, Wilson's phalaropes, long-billed curlews, upland sandpipers, and marbled godwits. Songbirds, like chestnut-collared longspurs and western meadowlarks, are raising their young. Burrowing owls, which nest on the Refuge in limited numbers, may be visible. In the fields along the roads, badgers can be seen lying on their mounds sunning themselves. White-tailed and mule deer can be seen in the grasslands of the Refuge. In the early morning, coyote can be seen scouting the Refuge. Yellow-bellied marmot are common among the rocks and roadways, but you must be quick, as they scramble when a car approaches. If you are patient, you may be lucky enough to view a long-tailed or least weasel in the grass near a dike before it dives into its hole. Pronghorn and white-tailed deer, with their young of the year, can be seen in the grasslands of the Refuge.
