BOOK NINETEEN OF OLAUS MAGNUS THE GOTH, ARCHBISHOP OF UPPSALA, ON BIRDS
PREFACE
THERE are numerous bird species in northern countries, of both land and water, which are well known to people among other nations, so that it would be superfluous to introduce any description of their features, particularly since this material has been amply treated by writers in the past. Nevertheless, with regard to these bleak lands and waters there are further aspects of the subject which I can point out, and these may serve to entertain the sympathetic reader without wearying him, and make it pleasurable for him to recall what he has read. A large number of people are amazed, and justifiably so, to discover that birds give proof not merely of being able to live, but also to reproduce their kind amid those fields which in every quarter lie hard under deep snowdrifts, waters everywhere frozen solid with ice, and long, cold nights many months on end.1
For this reason no one should draw hasty conclusions (as Plato strongly advises at the outset of his Laws), denying or disputing the character of something unknown because it is difficult to gain information about it. First he should pursue a keener enquiry, understand more accurately, and determine with preciser judgment what the artist Nature has the power to create, and having created it, to regulate by her laws.2 There are many phenomena which, even though they can be seen, escape the perception of human beings, and will sooner breed astonishment among investigators than beget knowledge. To give Platoâs opinion once more, scientists who are unwilling to maintain or believe a concept unless they have grasped it with their senses deserve only to be rated as pitiful.3 4That sound naturalist and geographer Celtis, who spent five years touring the whole of Germany, might be able to satisfy these critics when he says: âI know nothing about birds as they are described in the most responsible writers, for there is no doubt that many types have ceased to exist and are no longer alive today, while many have reappeared in Nature which were formerly absent. I should imagine this has occurred through a new configuration of the celestial bodies, always supposing that the world is capable of revealing anything fresh.â4 Such are Celtisâs words. Pliny lends his support to the idea in Bk X, Ch. 15: âMoreover there are a great many kinds of bird depicted in Etruscan lore which have not been observed for generations. It is remarkable that these have now become extinct, considering that some species are plentiful even where they are ravaged by manâs gluttony.â5

CHAPTER ONE
On the many different types of bird, and the distinctions between them
THERE are classifications to be made among birds in the worldâs cold regions, just as everywhere else. 1For example some, like eagles, are carnivorous, some, such as geese, are seed-eaters, some, including crows, consume any food they chance to come upon, some devour worms, as domestic fowl do, while certain birds, swallows among them, take their nourishment as they swoop to and fro in the air. There are differences too in the disposition of birds to associate with their fellows: eagles, hawks, and others that are bent on prey do not mingle with each other at all; by contrast, cranes and doves love to be sociable. Some birds, such as storks and swallows, are migratory, others, including hawks and jackdaws are submissive to handling and can be tamed by being stroked. Swallows and their like enjoy a home shared with men, while others, turtle-doves for instance, haunt solitary places, seeking sustenance where they can relish their freedom. Birds such as magpies set up a jabbering noise, while others are warblers,1 like the blackbird. Owls are of the sort that hoot by night, though nearly all other birds sing in the daytime. Some, as cuckoos do, make themselves heard in the summer months, but others, among them sparrows and eagles, make their voices heard all the year round. Others again mimic human speech, of whom parrots, like infrequent guests from abroad, are a source of delight in northern countries, for they will also let slip the secrets of the household in their talk.2
Classifications among birds
Another difference
3Certain birds are the subjects of kings, as for example cranes and bees; some, including starlings, get clean by rubbing themselves vigorously in ashes or sand; woodpeckers, rooks, and others govern themselves. Certain ones reveal themselves rather rarely, as ravens, falcons, magpies, and sparrows, when any of these are of a white hue. There are great differences between their respective voices and behaviours: eagles are rapacious, cocks lecherous, peacocks attentive to themselves, doves amorous, partridges crafty and jealous, ostriches, which are never seen in the North, cruel, though men put up with their natures; again, the magpie is a chatterbox, the jackdaw a thief.3
4Other distinguishing features between types of bird are their feet and beaks. Eagles and falcons, for example, have crooked talons, geese and almost all water-fowl, webbed feet. Another division occurs in that some transform their colour, as do thrushes and, in their old age, cranes. Others change their voices, for example hens; others, like the blackbird and nightingale, change both their plumage and their song;4 some, such as the swan, only sing when they are old and then become heralds of their own death;5 6some sing sweetly in summer, but harshly in winter; others, like jays, will change their tune and sing with a different call every day; others, turtle-doves and swallows among them, remain silent during winter; finally, certain birds alter their melody in winter, others in summer.6

CHAPTER TWO
More on the distinctions between birds
1CERTAIN birds, too, that are eager for prey, as I have said above, I avoid company. Because they are eager to take prey or to watch for places to lie in wait, they do not meet with one another except through the bond of mating; greed shuns the fellowship of many. Birds of prey are sharp-sighted, for when they fly high up they need to be able to see into the far distance and deep down below them. Their feathers moult and then grow again as vigorously as before. They rear only two chicks, and, as the custom is with eagles, if more are produced, toss them from the nest. Unlike fish, all such birds hunt species other than their own. Only the sparrow-hawk lacks this sense of loyalty. If hunting-birds want to fly off they are brought back with a lure.
Birds of prey
Greed shuns fellowship
Birds may be classified by the ways in which they take their food. Some that feed on flesh have curving beaks with which to hold it; others that eat seed have thin bills, and some broad, like water-fowl, so that they can grub up food from below the surface. Certain birds have longer beaks and legs than the average, others hold their necks upright. Vulturesâ beaks become bent when they grow old. The owl is stripped of its plumage by the other birds. The rest moult when they hatch out their young. One type of bird has feathers that resemble a helmet, standing up from the centre of its head. The vulture stuns its prey, or its adversaries, by beating...
