See me for directions to these places. Wichita Mountains National Wildlife Refuge, north of Lawton, Comanche Co, OK, about 300 km from Sherman. This is a large refuge in the mid-grass prairie of western Oklahoma, with about 9000 ha in the public access area. Good for several bird species that are rare around Sherman. This is also a good place to observe prairie dogs as well as large mammals such as bison and elk.
Bison have horns that are a foot long, and curve strongly upward.
There are several gorings of ignorant tourists in the refuge each year. Operated by US Fish and Wildlife Service. There may be others that have material of interest to you. The following journals contain articles on behavior, but are not in our library. Be aware that this process takes some time.
