Regional specialties that breed at UCSP include Field Sparrow, Northern Cardinal, both Eastern and Spotted Towhees, Whip-poor-wills, Northern Bobwhite, and Wild Turkeys. UCSP also has breeding records for Scarlet Tanagers and Eastern Meadowlarks, both of which are very rare nesters in southeastern South Dakota. Species that can be found in fall include Long-eared Owl, Ruby-crowned Kinglet, Golden-crowned Kinglet, Red Crossbill, Purple Finch, Broad-winged hawk, Harris's Sparrow, and Clay-colored Sparrow.
