Peregrine Falcon Falco peregrinus
Peregrine Falcon sitting on a fence post on a west fjordur in Iceland. We passed this beautiful creature along the road. As we came to a stop, put the car in reverse, and pulled up next to him, he simply sat still and watched our every move.
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. Experts recognize 17 to 19 subspecies which vary in appearance and range; there is disagreement over whether the distinctive Barbary Falcon is represented by two subspecies of Falco peregrinus, or is a separate species, F. pelegrinoides.
