One species of falcon is endangered.
More Info: The northern aplomado falcon is the only falcon of the United States that is currently listed as an endangered species under the Endangered Species Act (ESA). The peregrine falcon was formerly listed as an endangered species in the United States but was removed from the list due to a positive recovery in the United States. The peregrine falcon was no longer considered an endangered species under the ESA in 1999.
Why is the Northern Aplomado Falcon Endangered?
The northern aplomado falcon was deemed an endangered species in 1986 due to habitat loss and contamination with organochlorine pesticides, which includes dichlorodiphenyltrichloroethane (DDT). DDT was a highly used pesticide prior to being banned in 1972. DDT’s negative effects on falcons include infertile eggs and causing eggshells to be extremely soft and breakable. The northern aplomado falcon habitat is open rangelands and savannas scattered with trees. Habitat loss occurred and is occurring primarily due to brush encroachment or human development. The original species range included southeastern Arizona, southern New Mexico, southern Texas, large portions of Mexico, and western coast of Guatemala. The species is currently believed to exist in the US within portions of Texas with an experimental population introduced in south New Mexico in an attempt to recover the species.
