Is as very pretty male but a bit skittish.

The peregrine falcon (Falco peregrinus), also known as the peregrine, and historically as the duck hawk in North America is a widespread bird of prey in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head and “moustache”. As is typical of bird-eating raptors, peregrine falcons are sexually dimorphic, females being considerably larger than males. The peregrine is renowned for its speed, reaching over 320 km/h (200 mph) during its characteristic hunting stoop (high speed dive) making it the fastest member of the animal kingdom. According to a National Geographic TV programme, the highest measured speed of a peregrine falcon is 389 km/h (242 mph).

The peregrine’s breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world’s most widespread raptor and one of the most widely found bird species. In fact, the only land-based bird species found over a larger geographic area is not always naturally occurring but one widely introduced by humans, the rock pigeon, which in turn now supports many peregrine populations as a prey species. Both the English and scientific names of this species mean “wandering falcon”, referring to the migratory habits of many northern populations.

While its diet consists almost exclusively of medium-sized birds, the peregrine will occasionally hunt small mammals, small reptiles, or even insects. Reaching sexual maturity at one year, it mates for life and nests in a scrape, normally on cliff edges or, in recent times, on tall human-made structures. The peregrine falcon became an endangered species in many areas because of the widespread use of certain pesticides, especially DDT. Since the ban on DDT from the early 1970s, populations have recovered, supported by large-scale protection of nesting places and releases to the wild.

The peregrine falcon is a well respected falconry bird due to its strong hunting ability, high trainability, versatility, and in recent years availability via captive breeding. It is effective on most game bird species from small to large.

The peregrine falcon has a body length of 34 to 58 centimetres (13–23 in) and has a wingspan from 74 to 120 centimetres (29–47 in).The male and female have similar markings and plumage, but as in many birds of prey the peregrine falcon displays marked reverse sexual dimorphism in size, with the female measuring up to 30% larger than the male. Males weigh 330 to 1,000 grams (0.73–2.20 lb) and the noticeably larger females weigh 700 to 1,000 grams (1.5–2.2 lb).

The back and the long pointed wings of the adult are usually bluish black to slate grey with indistinct darker barring (see “Subspecies “below); the wingtips are black. The white to rusty underparts are barred with thin clean bands of dark brown or black.The tail, coloured like the back but with thin clean bars, is long, narrow, and rounded at the end with a black tip and a white band at the very end. The top of the head and a “moustache” along the cheeks are black, contrasting sharply with the pale sides of the neck and white throat The cere is yellow, as are the feet, and the beak and talons are black The upper beak is notched near the tip, an adaptation which enables falcons to kill prey by severing the spinal column at the neck. The immature bird is much browner with streaked, rather than barred, underparts, and has a pale bluish cere and orbital ring.

The peregrine falcon reaches faster speeds than any other animal on the planet when performing the stoop which involves soaring to a great height and then diving steeply at speeds of over 320 km/h (200 mph), hitting one wing of its prey so as not to harm itself on impact. The air pressure from such a dive could possibly damage a bird’s lungs, but small bony tubercles on a falcon’s nostrils guide the powerful airflow away from the nostrils, enabling the bird to breathe more easily while diving by reducing the change in air pressure. To protect their eyes, the falcons use their nictitating membranes (third eyelids) to spread tears and clear debris from their eyes while maintaining.
