Northern Prairie Wildlife Research Center
Black Eagle, Montana
The refuge is located at the western end of the famed Prairie Pothole Region, an area characterized by millions of wetlands or "potholes" which serve as the nursery for the bulk of the Nation's waterfowl. These wetlands also harbor scores of other bird and wildlife species dependent on wetlands, including many endangered species.
What you'll see at Benton Lake is a glimpse into pre-settlement times, when the prairie sky was alive with ducks, geese, swans and shorebirds each spring and fall, and the marshes teemed with downy young each summer. Enjoy and help protect this natural heritage!
SEASONAL BIRDING HIGHLIGHTS
Spring. Beginning in mid-March large numbers of pintails, mallards and tundra swans appear as ice leaves the lake. From several hundred to several thousand snow geese arrive and stay for a week or more. Waterfowl in breeding plumage have paired off and begin to seek nesting sites. As the weather warms, more and more species arrive, with shorebirds the last to make their appearance. Endangered bald eagles and peregrine falcons are often seen in the spring. Canada geese with young may be seen as early as late April, and some duck broods in late May. Pheasants and sharp-tailed grouse begin courtship antics.
Summer. By June all birds that will nest at Benton Lake have arrived. Broods of ducks become a common sight and the refuge is one of the best places in the country to see them in large numbers. Colonial nesting birds like eared grebes and Franklin's gulls are raising their young and a lot of racket. Songbirds are busy raising their young and if you're lucky, you may see burrowing owls which nest on the refuge in limited numbers.
Fall. Shorebird numbers peak once again during the early fall migrations. Waterfowl begin to "stage" on the marsh in preparation for migration further south. Large concentrations of raptors appear, most notably Swainson's hawks. Bald eagles are most commonly seen at this time, especially mid to late October and early November. Several thousand tundra swans mark the beginning of the end of migration. Refuge grasslands take on their subtle, but beautiful, fall colors.
Winter. Great horned owls often move into shelterbelts in winter. Other hardy raptors seen occasionally include goshawks, rough-legged hawks and snowy owls. Few songbirds are present, but include horned larks, longspurs, chickadees and sometimes snow buntings. Shrikes are more common than at other times of the year. Pheasants and gray partridge sightings are more common as they spend more time "exposed" in search of food. Bird and other wildlife tracks left in the snow add interest to a bleak, yet beautiful landscape.
Your vehicle makes a good blind to observe most marsh and grassland species. Early morning and evening hours are best since wildlife is most active then. Slowly walking along refuge shelterbelts is a good way to see sparrows and other songbirds. Much of the refuge is open to birding, but check the Public Use Regulations designed to protect sensitive areas. You are also encouraged to stop at the office and visit with refuge staff about the latest bird sightings and species concentrations. We are here to help!
This list of 199 bird species represents observations since 1961 when the refuge was first staffed. Many of the records have come from birdwatchers since that time. An additional 12 species of accidental occurrence are noted at the end of the list.
