About, 3-4, sometimes 2-5 rarely 6 eggs are hatched. Eggs are usually, whitish pale, and reddish brown, and have heavy brown spots and marks. Peregrine parents usually incubate the eggs for about a month until the eggs hatch. Female stays with young at first, while male brings food for her and for young; later, female hunts also. Parents rotate, incubation too. Peregrine Falcon chicks, called eyases, eat an incredible amount of food - in six days, they double their weight, and at three weeks are ten times their size at birth! Newly hatched chicks are wet and covered with white down. But by three weeks of age, brownish juvenile feathers can be seen poking through the white fuzz. By five or six weeks of age, the white fuzz has been completely replaced by brown feathers.Some peregrine falcons migrate in the winter from their nesting grounds in the Arctic all the way to South America—a round-trip distance of up to 15,500 miles (24,945 kilometers). They make the return trip north when it's time to mate and lay eggs.

Peregrine Falcons diet consist of smaller birds like pigeons, Bigger birds like geese,, sometimes insects, and rarely small mammals like bats. Pigeons are often favored prey around cities, and ducks and shorebirds often taken along coast. They catch their prey in mid-air. The most common prey for peregrine falcons is other birds. In fact, other birds make up 77% to 99% of their diet! Peregrine Falcons eat mostly birds, of an enormous variety—450 North American species have been documented as prey, and the number worldwide may be as many as 2,000 species.  However, they are not completely free from predators. Adult peregrine's  may be killed by other large birds of prey, such as great horned owls , gyrfalcons,and golden eagles. Nestlings and fledglings may be taken by mammal predators such as cats , bears, wolverines or foxes . This happens more often in nests that are closer to the ground.

Peregrine falcons are among the world's most common birds of prey and live on all continents except Antarctica. Peregrines live rarely in cold tundra, sometimes hot deserts, from sea level to high in mountains.Peregrine Falcons are seen perching or nesting on skyscrapers, water towers, cliffs, power pylons, and other tall structures, in a city. Peregrine falcons tend to build nest, up higher so predators will not eat, them. Breeding Peregrines defend the immediate area of the nest from intruders, but hunt over a much larger area. Peregrine falcons usually have 1 parents stay with the eyas, while the other is hunting. Peregrines don't build nests. They usually just find a shallow dip in some rocks or scrape a depression in the soil on the ledge of a cliff, or even use the ledge of a building. Peregrine Falcons nest on cliffs from about 25–1,300 feet high

In some cases they, will reach 240 miles per hour!  Peregrines usually hunt with either a swift chase or a fast dive.When hunting, Peregrines start by watching from a high perch or by flapping slowly or soaring at great height. They then catch the bird and bite through the neck to kill it. Peregrine Falcons do have other hunting methods, including level pursuit, picking birds out of large flocks, and occasionally even hunting on the ground.

Adults are blue-gray above with barred underparts and a dark head with thick sideburns. Juveniles are heavily marked, with vertical streaks instead of horizontal bars on the breast. As with most raptors, males are smaller than females, so Peregrines can overlap with large female Merlin's or small male Gyrfalcons. They are usually the size of a crow, may be smaller or bigger. They have acute vision, And a third eyelid to help when flying fast, so it can see its prey. Their Wingspan is 74 to 120 cm. The length of their body is 34 to 58 cm. They weight around 0.73 lbs to 3.3 lbs. Females are usually bigger than the male. ]]> 2018-03-28 21:18:10 UTC https://padlet.com/jw049748/x6ke3pyygsse/wish/247085037 History/Threats jw049748 https://padlet.com/jw049748/x6ke3pyygsse/wish/247087500 In 1947- The DDT introduced for use as a pesticide in the U.S.
In 1970 - Two of the three subspecies of peregrine falcon (American and Arctic) are classified as endangered.
In 1972 - The Environmental Protection Agency outlaws DDT as a pesticide due to its link to the thinning of eggshells which reduces hatching success.
In 1975 - Survey indicated only 324 nesting pairs exist in North America, compared to approximately 3,875 prior to DDT usage.
In 1974 to 1994- In the western U.S., 2,722 peregrines were released 
In 1994-Arctic peregrine falcon is delisted due to recovery.
In 1999 - American peregrine falcon is delisted due recovery.

These are one of the most successful species recoveries in the world.

It's scientific name is scientific name is Falco Peregrinus. They are commonly referred to as the Duck Hawk. 

2) The falcon’s prey is struck in one wing so the falcon does not injure itself.

3) Although they have a high mortality rate, Peregrines have been known to live as long as 15 years 

4) The Peregrine Falcon’s upper beak is notched near the tip, an adaptation which enables falcons to kill prey by severing the spinal column at the neck

5) The Peregrine Falcon is the largest falcon over most of the continent]]> 2018-03-29 13:44:46 UTC https://padlet.com/jw049748/x6ke3pyygsse/wish/247249160
