I, HABITAT USE BY SMALL MAMMALS IN AN INTENSIVELY MANAGED GRASSLAND WILDLIFE SANCTUARY- YEAR 3
The Short-eared Owl (Asio flammeus) and the Northern Harrier (Circus cyaneus) are listed as endangered in Illinois (IESPB 1992). Both species of raptor have become regular winter residents at Prairie Ridge State Natural Area (PRSNA) in Jasper Co., and have recently been observed nesting there in the...
