  1. The Endangerment Status of Peregrine Falcons Margaret Rolling Hills 2006

  2. The peregrine falcon is a magnificent raptor, the lord of the sky. However, this beautiful bird is threatened by extinction. There are many reasons the peregrine became endangered. One of the most dangerous things that effected the peregrine was D.D.T(Dichloro-Diphenyl-Trichloroethane). D.D.T was a bug pesticide used during World War Two and after. Raptors, especially peregrines, are prone to D.D.T. Small rodents digested the D.D.T and they in turn were digested by raptors. D.D.T caused the shells of peregrine eggs to be too thin and crack when incubation started. Luckily, D.D.T is now banned from the U.S.

  3. Another reason peregrines were endangered was because of their low production rate. A peregrine female lays two to five eggs a year. Natural predators and humans are also reasons why the peregrine became endangered. Humans endanger peregrines by shooting, poisoning, stealing, and destroying their habitats.

  4. Peregrines and other endangered species are protected by the endangered species act (ESA or the Act). The Act was founded in 1973. The Act has many purposes. One thing it does is to preserve ecosystems where endangered or threatened species live. It also allows the President to help another country with an endangerment plan. This act is vital to the survival of the peregrine because it prohibits anyone from taking an endangered species out of the United States. Anyone who does pays a fine up to $50,000 and can possibly spend time in jail.

  5. The number of peregrine breeding pairs has drastically changed. The cause of that was D.D.T. Prior to World War Two (before 1940) there were about 350-400 breeding pairs in the Eastern United States. In 1997 the peregrine population reached 174 pairs in the same region. The peregrine population dropped from 176 to 226 breeding pairs in only about 58 years. That is how much damage D.D.T inflicted on the peregrine falcon. Photo by Scott Wright

  6. Photo by Scott Wright Now that you have realized how much peregrines have suffered at the hands of humans in the form of D.D.T, help then by protecting our environments. We need falcons and should protect them. The peregrine falcon is a symbol of the wild, of endangerment, and now of recovery.
