FALCONRY.

Largest of all the falcon species, the Gyrfalcon is the dream of most falconers', however price can put them beyond the pocket of most. Quarry varies from corvids to gulls, grouse to pheasant, ducks to geese and in days gone by such protected species as Red Kites and Herons.

As with all birds of prey it is best to get the advice of people who regularly fly the bird you wish to have. Dr Chris Eastham a breeder and flier of Gyrfalcons says, "In falconry, gyrfalcons may be successfully flown from the hood or from waiting-on flights.  However, they are extremely intelligent birds and must be trained and flown correctly, and in a suitable environment."

NB. If you buy one of these raptors it should be fitted with a closed leg ring and have an Article 10 form with it (any queries check with DEFRA).
