Abstract

Since the time of settlement, at least 17 species (9%) of birds have disappeared as nesters in Iowa. Nine species were lost before 1900, another two before 1950, and six since 1950. Five species have been successfully introduced into Iowa, and four of these now are abundant in the state. A number of other species have benefited from human development and have increased in numbers since settlement. An additional 29 species have populations that seem endangered or threatened and may disappear before the end of this century.
