Nesting Status Of The Cooper's Hawk In Iowa: 1988-1996, David. J. Conrads
Nesting Status Of The Cooper's Hawk In Iowa: 1988-1996, David. J. Conrads
Journal of the Iowa Academy of Science: JIAS
The Cooper's Hawk was once considered a common nesting species in Iowa. Organochlorine pesticides and their residues, along with habitat loss contributed to its decline throughout the Midwest after the 1940's. This species was classified as endangered in Iowa in 1984, but recent trends in nests found indicate that the population of these hawks has increased. Since April 1988, 53 nests have been discovered in Iowa. Due to the apparent population growth, this species was removed from Iowa's endangered species list in 1994.
