Gyrfalcon For Sale
Gyrfalcon For Sale, Buy Gyr-falcon online. The gyr-falcon is a bird of prey (Falco rusticolus), the largest of the falcon species. The abbreviation gyr is also used. It breeds on Arctic coasts and tundra, and the islands of northern North America, Europe, and Asia. It is mainly a resident there also, but some gyrfalcons disperse more widely after the breeding season, or in winter. Individual vagrancy can take birds for long distances. Its plumage varies with location, with birds being coloured from all-white to dark brown. These colour variations are called morphs. Like other falcons, it shows sexual dimorphism, with the female much larger than the male. For centuries, the gyrfalcon has been valued as a hunting bird. Typical prey includes the ptarmigan and waterfowl, which it may take in-flight; it also takes fish and mammals. cockatoo parrots For Sale, Parrots for sale, Buy Scarlet Macaw, Buy parrots, Macaw parrots for sale, parrots shop, parrots store, Gyrfalcon For Sale birds for sale, Buy Gyrfalcon Birds
Gyrfalcon For Sale, The gyrfalcon is a very large falcon, being about the same size as the largest buteos (buzzards) but probably are slightly heavier.

Females are bulkier and larger, at 51 to 65 cm (20 to 26 in) long, 124 to 160 cm (49 to 63 in) wingspan, and of 1,180 to 2,100 g (2.60 to 4.63 lb) weight, with average weights of 1,585 or 1,752 g
Gyrfalcon For Sale, (3.494 or 3.862 lb) An outsized female from eastern Siberia was found to have scaled 2,600 g (5.7 lb)Among standard measurements, the wing chord is 34.5 to 41 cm (13.6 to 16.1 in), the tail is 19.5 to 29 cm (7.7 to 11.4 in), the culmen is 2 to 2.8 cm (0.79 to 1.10 in) and the tarsus is 4.9 to 7.5 cm (1.9 to 3.0 in) The gyrfalcon is larger, broader-winged and longer-tailed than the peregrine falcon, which it is known to hunt. It differs from the buzzard in general structure, having pointed wings.
Gyrfalcon For Sale, The gyrfalcon is a very polymorphic species, so its plumage varies greatly. 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. 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. The species shows no sex-based colour differences; juveniles are darker and browner than adults.
The black color seems to be sex-linked and to occur mostly in females; it proved difficult for breeders to get males darker than the dark side of slate grey. A color variety that arose in captive breeding is “black chick”.

Gyrfalcon For Sale, The gyrfalcon almost invariably nests on cliff faces. Breeding pairs do not build their own nests, and often use a bare cliff ledge or the abandoned nest of other birds, particularly golden eagles and common ravens. The clutch can range from 1 to 5 eggs, but is usually 2 to 4. The average size of an egg is 58.46 mm × 45 mm (2.302 in × 1.772 in); the average weight is 62 g (2.2 oz). The incubation period averages 35 days, with the chicks hatching at a weight of around 52 g (1.8 oz). The nestlings are brooded usually for 10 to 15 days and leave the nest at 7 to 8 weeks. At 3 to 4 months of age, the immature gyrfalcons become independent of their parents, though they may associate with their siblings through the following winter.
Gyrfalcon For Sale, The only natural predators of gyrfalcons are golden eagles, and even they rarely engage with these formidable falcons. Gyrfalcons have been recorded as aggressively harassing animals that come near their nests, although common ravens are the only predators known to successfully pick off gyrfalcon eggs and hatchlings. Even brown bears have been reportedly dive-bombed.Buy Gyr-falcon online. Humans, whether accidentally (automobile collisions or poisoning of carrion to kill mammalian scavengers) or intentionally (through hunting), are the leading cause of death for gyrfalcons. Gyrfalcons that survive into adulthood can live up to 20 years of age.
As F. rusticolus has such a wide range, it is not considered a threatened species by the IUCN. It is not much affected by habitat destruction, but pollution, for instance by pesticides, depressed its numbers in the mid-20th century, and until 1994 it was considered “Near Threatened”. Improving environmental standards in developed countries have allowed the birds to make a comeback.
Interaction with humans:
The gyrfalcon has long associated with humans, primarily for hunting and in the art of falconry. It is the official bird of Canada’s Northwest Territories. The white falcon in the crest of the Icelandic Republic’s coat of arms is a variety of gyrfalcon. The white phase gyrfalcon is the official mascot of the United States Air Force Academy.
In the medieval era, the gyrfalcon was considered a royal bird. The geographer and historian described certain northern Atlantic islands west of Ireland where these falcons would be brought from, and how the Egyptian Sultan paid 1,000 dinars for each gyrfalcon (or, if it arrived dead, 500 dinars). Due to its rarity and the difficulties involved in obtaining it, in European falconry the gyrfalcon was reserved for kings and nobles; very rarely was a man of lesser rank seen with a gyrfalcon on his fist

Gyrfalcon For Sale, Falcons are known to be very susceptible to avian influenza. Therefore, an experiment was done with hybrid gyr-saker falcons, which found that five falcons vaccinated with a commercial H5N2 influenza vaccine survived infection with a highly pathogenic H5N1 strain, whereas five unvaccinated falcons died. Thus, both wild and captive gyrfalcons can be protected from bird flu by vaccination
