Peregrines live in areas with cliff faces, so they tend to like sea cliffs and moorland they are also found in city centres because the high rise buildings look like cliffs. They are found in every continent apart from the arctic and the ant-arctic.
They feed mainly on birds, usually larger than themselves, sea peregrines eat gulls, puffins, and other sea birds, country peregrines eat game, occasionally rooks and crows and they both catch pigeons and duck with great style and aplomb. They don't eat fish at all.
The reason a peregrine can survive when at great altitude is because the nairs (nostrils) are spiraled, and when they stoop (dive) after their prey, the spiralling in the nairs baffled the wind so they can still breath, and they have been known to stoop from several thousand feet.
Peregrines are rarly hunted by humans, basically because they are protected in most countries, although they are occasionally shot, poisened, snared and trapped by those few who should be hung. Many other animals are capable of killing peregrines, other peregrines being the worst culprit, this is called raptor divorce, if the female you are trying to breed with doesn't like you, she will kill and eat you given half a chance, females are bigger and more powerful than males, although the are slower and less manouverable. Other animals include Eagles, Hawks etc, Foxes if the falcon is on or low to the ground, mink, ferrets, weasles and stoats for the same reason, and i have known peregrines being killed by rooks and crows because the falcon has caught them and the corvid has got the upper hand on the floor.
The feathers are mainly blue and white, but they do range in colour depending on the species of peregrine, there are about 12 to 13 diferent species of peregrine depending on what your veiws are on the shaheen and barbary, ranging from almost white to black with a bit of red and pink in there somewhere, the african peregrine is pratically black and pink. the feathers tend to be striped depending on where on the body they have come from.
When pairs copulate they start by calling for a member of the opposite sex, they will bow and chup to one another, food pass and long standing pairs will indulge in mutual preening. when copulation occurs the male will jump in the back of the female, sat on his haunches with his feet balled up, she cocks her tail to one side and he drops his right down. there is no actual intercourse and the male has no penis, but the rub cloaicas and when the male ejaculates the famale draws the semen inside herself. the eggs then take about 28-31 days to incubate, and the female will build up a clutch, brooding them before she begins to properly incubate, this way all the youngsters will hatch at roughly the same time.
And yes, Peregrein Falcone should be spelt with capitals no matter where they are in a sentence although i haven't done it much in these answers.
A few more bits of info.
the male of the species is known as a teircel, when you say peregrine falcon, you are refering to the female, the male is a peregrine teircel.
They are the fastest animal on the planet, one such bird has been recorded at reching speeds over 250 mph in a stoop (dive)
The peregrine almost became extinct in the 60's. This was due to the use of DDT, this pecticide was causing infertility and egg shell weakness, so birds were not being born that should have been. and if it wasn't for falconers the peregrine would have become extinct, it was falconer that first learnt how to breed falcons in captivity when this disaster first struck. Visit http://www.peregrinefund.org/default.asp for more details.
they have been known as blue hawk, blue-backed falcon, great blue hawk, spotted falcon, passenger falcon, duck hawk, sharp-winged hawk, great hawk ofbenbulben, hawk of cadia, gull hawk, puffin hawk, game hawk, hunting hawk, stock hawk, faakin hawk, goshawk, perry hawk, falcon gentle and teircel gentle.
The stripes, or moustace, down the face, either side of the beak are called mallor stripes.

The Peregrine Falcon (Falco peregrinus), sometimes formerly known in North America as Duck Hawk, is a medium-sized falcon about the size of a large crow: 38-53 cm (15 to 21 inches) long. some populations are migratory. It has a wingspan of about 1 metre (40 inches). Males weigh 570-710 grams; the noticeably larger females weigh 910-1190 grams.
The Peregrine Falcon is the fastest creature on the planet in its hunting dive, the stoop, in which it soars to a great height, then dives steeply at speeds in excess of 300 km/h (185mph) into either wing of its prey, so as not to harm itself on impact. Although not self-propelled speeds, due to the fact that the falcon gathers the momentum and controls its dive, capture (if any) and landing in its own right, technically there is no faster animal. The fastest speed recorded is 390 km/h (242.3mph). The fledglings practice the roll and the pumping of the wings before they master the actual stoop.
Peregrines in mild-winter regions are usually permanent residents, and some birds, especially adult males, will remain on the breeding territory. However, the Arctic subspecies migrate; tundrius birds from Alaska, northern Canada and Greenland migrate to Central and South America, and all calidus birds from northern Eurasia move further south or to coasts in winter.
Peregrine Falcons feed almost exclusively on birds, such as doves, waterfowl and songbirds, but occasionally they hunt small mammals, including bats, rats, voles and rabbits. Insects and reptiles make up a relatively small proportion of their diet. On the other hand, a growing number of city-dwelling Falcons find that feral pigeons and Common Starlings provide plenty of food.
Peregrine Falcons breed at approximately two or three years of age. They mate for life and return to the same nesting spot annually. Their courtship flight includes a mix of aerial acrobatics, precise spirals, and steep dives. The male passes prey it has caught to the female in midair. To make this possible, the female actually flies upside-down to receive the food from the male's talons. Females lay an average clutch of three or four eggs in a scrape, normally on cliff edges or, increasingly, on tall buildings or bridges. They occasionally nest in tree hollows or in the disused nest of other large birds.
The females incubate the eggs for twenty-nine to thirty-two days at which point the eggs hatch. While the males also sometimes help with the incubation of the eggs, they only do so occasionally and for short periods.
Thirty-five to forty-two days after hatching, the chicks will fledge, but they tend to remain dependent on their parents for a further two months. The tercel, or male, provides most of the food for himself, the female, and the chicks; the falcon, or female, stays and watches the young.
The average life span of a Peregrine Falcon is approximately eight to ten years, although some have been recorded to live until slightly more than twenty years of age.
The Peregrine Falcon became endangered because of the overuse of pesticides, during the 1950s and 1960s. Pesticide build-up interfered with reproduction, thinning eggshells and severely restricting the ability of birds to reproduce. The DDT buildup in the falcon's fat tissues would result in less calcium in the eggshells, leading to flimsier, more fragile eggs. In several parts of the world, this species was wiped out by pesticides.
Peregrine eggs and chicks are often targeted by thieves and collectors, so the location of their nest should not be revealed, unless they are protected.
