The largest falcon is the gyrfalcon at up to 65 cm (26 in) in length. The smallest falcon species is the pygmy falcon, which measures just 20 cm (7.9 in). As with hawks and owls, falcons exhibit sexual dimorphism, with the females typically larger than the males, thus allowing a wider range of prey species.
Same hardware, more requests. Falcon turns around requests significantly faster than other popular Python frameworks like Django and Flask. For an extra speed boost, Falcon compiles itself with Cython when available, and also works well with PyPy. Considering a move to another programming language? Benchmark with Falcon+PyPy first!

Sleek, fast-flying large falcon. Always look for a grayish back in adults, long wings that almost reach the tail tip, and powerful but slender build. Dark mark below each eye varies in shape and size. Juveniles are more heavily patterned below than adults, and can be quite brownish above.
Powerful and fast-flying, the Peregrine Falcon hunts medium-sized birds, dropping down on them from high above in a spectacular stoop. They were virtually eradicated from eastern North America by pesticide poisoning in the middle 20th century.
Jul 15, 2024 · Peregrine falcon, the most widely distributed species of bird of prey, with breeding populations on every continent except Antarctica and many oceanic islands. Its diving speed during flight is more than 300 km (186 miles) per hour, making it not only the world’s fastest bird but also the world’s fastest animal.
Peregrine Falcons are the largest falcon over most of the continent, with long, pointed wings and a long tail. Be sure to look at shape as well as size—long primary feathers give the Peregrine a long-winged shape.
