R & E: A local colonial breeder along eroded banks fo almost all rivers north of and including the Missouri River. In addition, occurs local along the entire Mississippi River drainage. Colonies are much more spotty in the Ozarks and Osage Plains. It probably has increased as a breeder since presettlement, as a result of an increase in nesting sites, especially roadside cuts.
