Introduced Birds of Illinois
Nine other species are
- Ruffed Grouse in NW Illinois may represent a remnant native population or wild dispersals from Wisconsin or Iowa. A very small population in Pope County may be the result of late 1950’s or early 1960’s releases of wild-trapped birds. All other populations in Union and Alexander county or extreme western Jo Daviess County are the results of wild-trapped birds released during the period 1982-94 and are not considered established.
- During the summers of 1991-98 Greater Prairie-Chickens from out-of-state were introduced into Illinois’ only remaining populations in Jasper and Marion counties.
- The native Wild Turkey population in Illinois was extirpated in the early 1900’s. Turkeys were first reintroduced in the Shawnee Forest in 1959 from out-of-state stock. Once established there, Illinois birds have been and continue to be introduced to unpopulated locations throughout the state.
- Peregrine Falcon was extirpated as a breeding species; the current breeding population is reintroduced.
