Throughout the medieval and early modern period, Icelandic gyrfalcons<\/a> were highly valued at the courts of European rulers and they were worth a fortune. Indeed, Frederick II (1194-1250), Holy Roman Emperor, already noted in his treatise De arte venandi cum avibus <\/em><\/a>that the best falcons for use in falconry were gyrfalcons (\u2026et isti sunt meliores omnibus aliis, Girofalco enim dicitur<\/i>). The reason for this was that of all falcon species, gyrfalcons (F<\/em>alco rusticolus<\/i>) are the largest and most powerful. Their plumage varies greatly from completely white to very dark, of which the white variety was the most valued hawking bird in the Middle Ages, and still is today. They only inhabit sub-arctic and arctic areas, with their highest population density in Iceland (one pair per 150-300 km\u00b2<\/span>). During the breeding season (roughly February to June) there are today 200-400 nesting pairs in Iceland, and in the winter the population increases to 1.000-2.5000 individuals, due to migrating birds from Greenland.<\/p>\n
\u201cOn 5 April [1584] I have dealt in my house with Augustin and Marcus Mumme, in the name of god, that they shall sail to Iceland in the name of god, and we agreed that I will give for each pair of falcons 11 \u00bd daler, and 2 tercel [male falcons] for 1 falcon, and what is blank shall be counted as a red [unmoulted] falcon. But what is white and moulted<\/a> once, or moulted twice and beautiful, for those I shall give them 20 daler for each falcon and 10 daler for a tercel. But what has moulted three times we shall agree upon with good will, and if god and luck provides them with white falcons, I will give the one who catches them black cloth for a jacket of 2 \u00bd ells, all of this is validated with a denarius dei<\/a> of 1 sosling each, and both brothers have promised with an oath to bring the best birds they can get and to take no birds away, neither in Iceland nor during the journey back, until they have all been delivered to me.\u201c<\/i><\/p>\n

Later documents tell us how the shipping of the falcons was done. During the 17th century, a Danish falcon ship went to Iceland annually to transport falcons from Iceland to Copenhagen. The falcons were kept below the deck and sat on poles which were lined with va\u00f0m\u00e1l<\/i><\/a>. During the journey, the birds were fed with meat of cattle, sheep or birds, dipped in milk, and when they were sick, they were fed with a mix of eggs and (fish) oil. Upon arrival of the birds in Hamburg, Mathias Hoep checked their health and quality and he considered them in good state after they had eaten three times and their feathers were not broken.<\/p>\n
