NOTE: To Manoj of Peoria, who asked about good locations for birding near Peoria.
Personally I don't know much about birding in the Peoria area (other than visiting there a couple of times). However, I have heard that the Chautauqua National Wildlife Preserve near Havana (which isn't far from Peoria) is an excellent place to spot birds. Below are a couple of links to a websites that mention birding in the Refuge... good luck - happy birding.
