What is the difference between a gyrfalcon and a peregrine falcon?
The Peregrine Falcon is smaller, with narrower, more pointed wings than a Gyrfalcon. Peregrines also have stronger facial markings, with a thick black mustache stripe that Gyrfalcons don’t have.
Is a gyrfalcon a hybrid?
Hybrid Gyrfalcons are not known to occur in the wild, but are common in falconry. Hybrids can appear nearly identical to one species or look like a combination of both species. Some falconry birds escape into the wild, but often have jesses (leather anklets) or rings on their legs.
What does a gyrfalcon sound like?
When alarmed, Gyrfalcons give a hoarse “kak kak kak” with several repetitions per second. They give a sharp “chup” when foraging or transferring food, repeating it up to 20 times. Other calls include chatters, wails, and low whines. The female’s calls are usually lower in pitch than the male’s.

Is a Gyrfalcon a hybrid?
How fast is a black falcon?
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 bird in the world, as well as the fastest member of the animal kingdom.
What is a gyrfalcon best known for?
falcons
Gyrfalcons are known as the largest and one of the fastest falcons in the world. Apart from this, these birds of prey are known as hunter birds who have very rare encounters with natural predators, keeping them at the top of the worldly food chain.
Is the gyrfalcon endangered?
Is there such a thing as a white gyrfalcon?
The black morph has a strongly black-spotted underside, rather than finely barred as in the peregrine. White form gyrfalcons are the only predominantly white falcons. Silver gyrfalcons resemble a light grey lanner falcon of larger size.
What are the archetypal morphs of the gyrfalcon?
The archetypal morphs are called “white”, “silver”, “brown”, and “black”, though they can be coloured on a spectrum from all-white to very dark. The brown form of the gyrfalcon is distinguished from the peregrine by the cream streaking on the nape and crown and by the absence of a well-defined malar stripe and cap.
How big is The wingspan of a gyrfalcon?

What kind of bird is a Greenland gyrfalcon?
Gyrfalcons hybridize not infrequently with sakers in the Altai Mountains, and this gene flow seems to be the origin of the Altai falcon. Some correlation exists between locality and colour morph. Greenland gyrfalcons are lightest, with white plumage flecked with grey on the back and wings being most common.
