The Supreme Aerial Predator

Falco peregrinus macropus

Few experiences in Nature can rival the experience of standing under a Peregrine Falcon as it brakes out of near vertical dive by suddenly spreading its wings and tail &emdash; resulting in a loud roar of air. One is left to wonder how mere flesh, blood and feathers can survive the awesome physical forces at play on the bird's frame.

It is with justification that Peregrines have been described as the 'ultimate predatory bird' or even as the 'Top Guns' of feathered hunters. The package of adaptations that has produced such an effective and formidable aerial predator includes:

• acute vision;
• streamlined and powerfully muscled bodies;
• narrow, tapered wings;
• short and sturdy legs;
• long, thin toes tipped with strong, curved talons;
• powerful bite.

The main prey of Peregrines is other birds, particularly pigeons, parrots, waterfowl, shorebirds and large songbirds. Some of these may be heavier than the falcon itself. Less commonly, birds and mammals will be taken from the ground.

Peregrines search for likely prey while on the wing, or from a high, commanding perch. Once it has located a potential victim, the falcon will launch a high speed attack; chasing the intended victim or diving vertically with wings closed. The speed that Peregrines reach as they dive has been estimated at more than 180 km/hr!
