Due to the large size, speed and alertness of the falcon, the falcon has few natural predators and even fewer that are actually airborne. Humans and wolves tend to be the main predators of the falcon on the ground and eagles and even large owls have been known to hunt the smaller species of falcon (and of course the young and inexperienced falcons) in the air. The eggs and chicks of the falcon are particularly vulnerable to being eaten.
Falcons have adapted in many ways to maximise their chances of survival in the skies. The falcon has tapered wings that allow the falcon to be more agile; incredibly acute eyesight which enables the falcon to spot prey on the ground far below; an aerodynamic body shape means that the falcon glides through the air more easily and a sharp pointed beak helps the falcon to grab and eat it's prey more effectively.
Falcons nest on high ground such as mountains and cliffs and in the tops of tall trees. This means that the vulnerable eggs and chicks of the falcon are in the safest place possible. Falcons start to breed when they are about a year old. Female falcons lay an average of 3 eggs per clutch and look after their chicks until they are big enough and strong enough to fend for themselves.
Falcons are generally solitary birds and only really come together to mate. Although falcons are known to stay in the same place, many species of falcon are migratory birds and have been known to travel more than 15,000 miles per year.
