The peregrine falcon is endangered by several factors:
1: Pesticides. During th 1950s - 70s, a 'mirical' pesticides was invented, the DDT (Dichloro-Diphenyl-Trichloroethane). But the pesticide has a great effect. It killed the insect efficiently, but the animals consuming the insects stored the DDT in the body. Raptors (not only the peregrine, but a massive range of animals) ate the animals gained massive amount of the pesticide, and the problem appeared. The pesticide interfered with the reproduction of the bird, thinning the eggshells which reduce the number of eggs that survived to hatching. In several parts of the world, such as the eastern USA and Belgium, this species became extinct as a result.
2: Hunting. The Peregrine Falcon have been shot by humans because they eat carrier birds. Carrier birds are used in France to deliver messages and because the Peregrine Falcon have been eating them messages couldn't go through.
3: Black markets. Peregrine eggs and chicks are often targeted by black marketeers and unscrupulous egg collectors. As a result, fewer survivors.
Luckily, the problem has been spotted. Governments have laws to protect the peregrine, and other bird or prey (they met the same or related problems). SPCAs have projects or something to protect the animals. And the peregrine now is globally wide spread, and the LUCN has grossed it out from the endangered list.
Yes. You may not see the peregrine flying in the sky, not even one, but it is normal. In fact the peregrine is a wild bird and is a bird of prey. Both characteristics shares the point of rare to be seen. So be patient, it may soon appear.

∙ 14y agoFalcons in general will not recover unless they stop breeding hybirds. because by breeding them we are not gaining anything for the wildlife. if we breed strait falcons we will recover. iam a falcons maniak. mad alot of research. and been alot of places to see there habitat

∙ 13y agothe population decreased because of DDT a pollution that cracked the eggs when the parent sat on it
Wiki User
∙ 9y agoThe pesticide DDT entering the environment made it difficult to incubate their eggs, as they would break easily. Since the banning of DDT, the peregrine has recovered.

How exactly does DDT harm peregrine falcon?
DDT is an insecticide that is no longer used. It caused peregrine falcon eggs to break open and kill the embryos very quickly.
When did the Peregrine Falcon become extinct?
From the 1950's to the 1970's, organochlorine pesticides such as DDT caused the eggshells of birds of prey, including falcons, to become dangerously thin, preventing many of them from hatching. After these pesticides were banned, captive breeding programs for Peregrine falcons were implemented with great success. The Peregrine falcon was removed from the US Endangered Species List on August 25th, 1999, and today they are considered Least Concern by the IUCN. This species is one of the greatest conservation success stories in history.

Are there endangered animals in Alaska?
The American peregrine falcon is one of the best known raptors in North America. Many people are aware of the population declines of this species due to problems with egg-shell thinning caused by persistent organic pollutants such as DDT. Populations of this species were driven to the brink of extinction and the peregrine falcon was federally listed as an endangered species in 1973. Reducing DDT in our environment provided peregrine falcons with a chance to recover and the population in Alaska has grown rapidly from 1980 to the present. The American peregrine falcon was removed from the endangered species list in 1999. American peregrine falcons were never common in Denali. The extensive alpine regions of Denali do not support high densities of prey favored by peregrines and the lowland areas don't contain many cliffs or rock outcrops for nesting. In 1988, Denali scientists documented the first breeding pair of peregrine falcons in Denali on a granite tor near Chilchukabena Lake. In 1989 these scientists found another pair breeding on a small bluff on the Toklat River and in 2002 they found two more pairs, all on the Toklat River. It appears that peregrines are moving into some of the lowland areas in Denali as their populations grow in interior Alaska.
