The numbers of Peregrine Falcons have diminishing by the use of poisonous chemicals such as DDT found in their food chain. Their food, for example fish, consume poisonous substances in their food and these fish are contaminated. In turn, the fish are eaten by the falcons and the poisonous substances are passed down to the falcon's body. These chemicals affect their reproductive organs and cause the shells of their eggs to become thin and brittle. These eggs are easily broken when the parents sit on them and the eggs are destroyed. Peregrine Falcon's are endanger due to the destruction of their habitat by human activities. They are also hunted for sport. In efforts to increase their population, release them into areas where they have become extinct have been undertaken.
