Various grassland birds may be seen along Refuge roads including grasshopper sparrow, western meadowlark, horned lark, upland sandpiper, long-billed curlew, burrowing owl, and northern harrier during the spring and summer months. Woodland habitats along the Niobrara River offer great birding opportunities during late spring and summer months. Depending upon the time of year, bison may be viewed from the Refuge roads. Refuge visitors have access to multiple trails and overlooks, and thousands of Refuge visitors connect with nature by floating the Niobrara River. The public is welcome to watch the fall bison roundup as well!
