The peregrine falcon's scientific name is Falco peregrinus, which means "falcon wanderer". The peregrine falcon is a raptor, or bird of prey. Peregrine Falcons are found on every continent except for Antarctica. Falcons live where the climate varies from cold places to warm places. Falcons typically prefer to live in high altitude locations like on mountains tops. It can survive in a wide variety of habitats including cities, the tropics, deserts, and the tundra. Some falcons migrate long distances from their wintering areas to their summer nesting areas. They are one of the most wide spread species of birds in the world. The peregrine falcon's role or niche in the Ecosystem is to eat smaller birds that will keep down the population down.

These weigh about two pounds, although, the females are slightly larger than the males. Adults have blue-gray wings, dark brown backs, a colored underside with brown spots, and white faces with a black stripe on their cheeks. They have a hooked beaks and strong talons. Peregrine falcons are the fastest flying birds in the world – they are able to dive at 200 miles per hour.

They are endangered throughout Canada. Populations in southern Canada were established with captive-bred young and remain small. Twenty years ago there were no breeding pairs in southern Alberta. Now there are 30 pairs across the province. The reason for their endangerment is the pollution of the waters where fish live, once the water is polluted the fish get it into their system and the eats the fish. This gets into the eggs of the falcon and when the female goes to sit on her eggs there are too soft and break. Things people are doing to help these animals is slowing down pollution. Also, people they are breeding and releasing these animals into the wild.
