Peregrine falcon

  1. 1. Peregrine Falcon Dylan Whitney
  2. 2. Common Name • Peregrine Falcon • Also known as: - Duck Hawk - Peregrine
  3. 3. Scientific Name • Falco peregrinus • Means “Falcon Wanderer”
  4. 4. Habitat • One of the most common birds in the world, peregrine falcons are found on every continent except Antarctica. In North America, they are found along the eastern, western and Gulf of Mexico coastlines, and inland throughout the Rocky Mountain region as well as throughout Alaska and Mexico. These birds prefer open habitats near water, and they have also adapted to urban environments, largely through repopulation programs. Northern and southern populations will migrate seasonally, and all peregrine falcons are nomadic in search of food.
  5. 5. Niche • Diet - Peregrine Falcons live mainly off other birds, such as pigeons, jays, and shorebirds. Rarely, however, they will feed upon mammals, reptiles, and insects. Prey is typically captured after a fast pursuit in the air, or a dive bomb. • Size - The body length of a Peregrine Falcon is 15-20 inches long, a wingspan of 3.5 feet, and can weigh anywhere between 1 1/4 pounds, to 2 3/4 pounds. • Housing Requirements - Peregrine falcons always live on a tall building, cliff, or any other tall structure. They can also live in man- made nests or boxes. • Climate Requirements - Peregrine falcons living in very extreme climates migrate during the winter to a place with a more mild climate, such as the United States or Canada. Falcons living in the Midwest often do not migrate, because the winters are not too extreme, and their food sources remain adequate.
  6. 6. Niche (continued) • Relationship with other species - The Peregrine falcon is almost always the predator, most Peregrines die of natural causes. However, in remote areas, Great Horned Owls, Martins, and snakes will feed on the young. • Age when they reproduce - Peregrine falcons will begin to reproduce at three years old. How many eggs will it lay? - The female Peregrine Flacon will generally lay three to five eggs at one time. • When is it active? - Peregrine falcons are active during the daytime, and hunt at dusk and at dawn, when it's prey is most active. • Living Habits - The Peregrine falcon is a solitary bird, and does not mate for life.
  7. 7. Physical Structures/Adaptations • Like all falcons they have long tapered wings and a short tail. These physiological adaptations equate to high speed maneuverability while in flight. • Falcons typically hunt small birds and they use their beaks and claws to swiftly immobilize and kill their prey while in flight. • These combined traits make the peregrine falcon a very successful predator. It is the fastest animal in the world; clocked at over 200 miles per hour during a stoop, or dive while in pursuit of a prey item. At that speed, any small bird that the peregrine falcon places in its sights is not getting away. • All falcons use their talons to latch onto prey while their sharp curved beak severs the prey’s spinal column at the base of the skull.
  8. 8. Average Life Span • 17 Years
  9. 9. Interesting Facts • The speed of a peregrine has been said to reach 175 miles per hour or more. Experiments conducted by scientists put the bird's diving speed at approximately 200 miles per hour and level flight at approximately 62 miles per hour. • Peregrines normally grow to 15 inches in length with a 40-inch wingspan.
  10. 10. Interesting Facts (continued) • Females are larger and more powerful than males. • Prey is caught in flight. Using its great speed, the falcon delivers a powerful blow to its prey with a half-closed foot. It retrieves the dead bird either in mid-air or after it falls to the ground.
  11. 11. Endangered Species Status • Populations crashed in 1950-1970 because of DDT poisoning; eastern population extirpated. It was declared an Endangered Species, and extensive efforts were made to reestablish birds in East, beginning with the work of Tom Cade in 1970 at the Cornell Lab of Ornithology, which eventually developed into the Peregrine Fund. • There are an estimated 1,650 breeding pairs in the United States and Canada.
