Large Blue/ Sortplettet Blåfugl

Maculinea arion

Wing span 33-41 mm. Looks like the female of Alcon Blue, but is known for its size, shining blue colour, the black wing-spots and the strong markings on the underside. The spots on the upperside may varie and sometimes lack completely.

Its flying time is in July. The habitat is warm heaths, dunes and pastures. It overwinters as a half-grown caterpillar in nests of the ant species Myrmica sabuleti. The fodderplants of the caterpillar are flower heads of thyme (Thymus) or marjoram (Origanum). When little the caterpillar falls to the ground and is found by an ant, who carries it down in its underground nest. The caterpillar produces a sweet secretion for the ants, while it is eating their eggs and larvaes. The caterpillar transforms into a butterfly in the ant-nest and crawls out from the entrance-hole without any attacks from the ants.

The flight of Large Blue is unsettled and low, but can also be quick, high and goal-oriented, if it is scared. It suns itself in bushes and often seeks nectare at thyme, sheepsbit scabious etc.

Large Blue was almost extinct after 1950. Since 1990 seen only in one spot at Møen and a couple of spots in North Jutland. Listed.

Protection of the species: the locality must not be fertilized, and the vegetation has to be kept low by a suitable management. Any intervention in order to protect the species demands the assistance of specialists.

Late August by Lake and Meadow

The Bride's Lake , Mid Jutland
In a legend a bride and groom were killed by driving their horse carriage out into a lake, which after this was called 'Brudesø' (Bride's Lake) , a story known from other places and countries. Why this lake in the lake district in the middle of Jutland has achieved the name 'Brudesø' is not known - whether young girls were sacrificed here as brides of the water spirit - or if a young couple commited suicide in a Romeo and Juliet tragedy - only imagination can tell.

Common Blue Butterfly and a Jade Creen bug, two small jewels

A Red-backed Shrike and a fine little Puffball. This red-backed shrike is here almost every time we come to this place. A permanent home for the shrike here at Brudesø.
Puffballs were traditionally used in Tibet for making ink. Most puffballs are not poisonous, but it takes some expertise to use them for food. Some often look similar to the deadly Amanitas, such as the Death cap mushroom.

Here is a lovely Queen of Spain Fritillary. It has such a beautiful underside with Mother of Pearl spots, but the wings are most often spread out. The Small Heath wears the finest little gown in light orange silken and with a layer of fine muslin, an evening dress for Scarlet O' Hara.

A Lythria purpuraria (cruentaria) and a Scarce Copper ( female); this little pretty Copper has grown in numbers in Jutland during the latest years.

A Common Blue in the fine flowering heather and a Bladder Campion. In Spain, the young shoots and the leaves of the Bladder Campion are used as food. The Danish name is blæresmælde, (like: to crack a bladder).When we were children, we pressed the bladders to make them crack. The flowers are special - they only give scent in the evening and the night.

In the corner of another lake were two Mute Swans proudly showing their pretty young ones.
It is the largest bird in Denmark. It was almost extinct, but total listing has caused that it is now nesting in every large Danish lake. In 1925 were only three pairs left, in 1950 about 300-400, in 1955 1000 and in 1978 4.000 pairs. The Mute Swan was in a viewer-voting of Danmarks Radio in 1984 elected Denmark's national bird.

Lythrum salicaria (Purple loosestrife) The Danish name is kattehale = Cat's Tail, and it might look like a cat's tail when it is swept by the wind among the other plants.
The plant with the yellow flowers is
Bidens. It is plant in the family Asteraceae. The common names beggarticks, bur-marigolds, stickseeds, tickseeds and tickseed sunflowers refer to the achene burrs on the seeds, most of which are barbed. The generic name refers to the same fact; it means "two-tooth".

Large-flowered Hemp-nettle (Galeopsis speciosa), the Greek name Galeopsis means a likeness to a cat, polecat or weasel, speciosa = beautiful flower.

Bride's Lake/Brudesø

This i Greater Duckweed, it is not as common as Lesser Duckweed. To the right looks like a spider's web but it is actually a web filled with caterpillars from a butterfly. I don't know which.
Click to enlarge pictures.

Lysimachia vulgaris, Danish: Almindelig Fredløs. The word fredløs means outlawed . Why it was given this name is a mystery to me! To the right a bird-observation tower. I have never been able to find a proper translation in English. I have now tried Google translation. They just tell me: tower. Can anyone help me?

A Woundwort and a Goldenrod. Woundwort is a Stachys, and Stachys officinalis was the most important medicinal herb to the Anglo-Saxons of early medieval Great Britain. The name woundwort derives from the past use of certain species in herbal medicine for the treatment of wounds.
Parts of some goldenrods can be edible when cooked. Goldenrods can be used for decoration and making tea. Goldenrods are, in some places, held as a sign of good luck or good fortune, but they are considered weeds in others.Goldenrod is a companion plant, playing host to some beneficial insects, and repelling some pests.

Two lovely butterflies, the Red Admiral and the Peacock. Their Latin names are spectacular: Peacock is Inachis io and the Admiral is Vanessa atalanta, suitable for such pretty creatures.

A Scarce Copper and a Glanville Fritillary in the flowering heather

A pair of mating Common Blue butterflies - and a Small Pearl-bordered Fritillary. This Fritillary is in decline in DK, where farming and foresting is most intense.

Russula mushrooms and a Moth. The main pattern of toxicity seen among Russula species to date has been gastrointestinal symptoms in those with a bitter taste when eaten raw or undercooked; many of these are red-capped species.

A Field Scabious and a Common Toadflax. Species of scabious were used to treat Scabies and many other afflictions of the skin including sores caused by the Bubonic Plague. The word scabies comes from the Latin word for "scratch" (scabere). Another name for this plant is Gipsy Rose.
Common Toadflax' Latin name is Linaria vulgaris, the members of this genus are known in English as toadflax, a name shared with several related genera. The scientific name means "resembling Linum"(flax), which the foliage of some species superficially resembles. The Danish name Torskemund means a Cod's mouth.

Now there are green fruits in the elderberry. They are fine for making capers. I once had a recipe and I once made a portion of green capers, but it takes too long to pluck the berries in the wood and to cleanse them and to cook them and so on.....I simply don't have the patience. But they were actually good - those green capers I had "produced". I have later seen that the green berries are considered poisonous and not advisable to use. So I shall not look for my recipe.

Roses with a wonderful scent and hips not yet ripe - but they are at least not poisonous , they are very healthy with lots of C-vitamins. A marmalade of hips and apples tastes so good!

Time to say goodbye to the lake and the heather. Can you see the bee in the top? It will fly home and make honey we can use for our bad throats next winter. If winter comes....

We'll go home when the cows go home. This is a small clique, having a meeting before they go home. We'll have a coffee-break.

Falconry in the Middle Ages

Gurre Castle Ruin, Zealand

Falconry , especially in medieval England.

In history no bird of prey has shared as close a relationship with humans as the falcon did during the Middle Ages, when the sport of falconry and hawking was an important part of life. It reigned as the most popular sport in England for more than four centuries. So important were falcons in England that the first laws aimed at protecting birds of prey were treated here. Perhaps no such stringent laws have ever been passed to protect a wild bird or animal.

Somehow wildlife conservation was born during the age of falconry. No one knows exactly where or when humans started using trained raptors to hunt for food, but a theory says that it probably came into existence by the nomads on the Asian steppes around 2000-1600 B.C., from where it spread east to China and west to Arabia, Persia and Europe.The first record of humans using birds of prey for hunting comes from an Assyrian bas-relief dated in the early part of the seventh century B.C. References to falconry in China are as early as 680 B.C., but one Japanese work states that falcons were used as gifts to Chinese princes during the Hsia dynasty, 206-220 B.C.

With the increasing trade falconry reached the Mediterranean about 400 A.D. Germanic tribes acquired the sport around the sixth century A.D., and by 875 A.D. it was practiced through western Europe and Saxon England.The first documented English falconer was the Saxon king of Kent, Ethelbert II (died 762), followed by Alfred the Great and Athelstan in the ninth century.
After the Norman conquest in 1066, new raptor species were introduced in England. The Normans restricted falconry to the upper classes, and peasants could be hanged for keeping hawks. Yeomen were allowed to use the short-winged hawks, like goshawks and sparrowhawks, to hunt for food, but only king and nobility were allowed to have the more noble long-winged falcons, like gyrfalcon, peregrine and merlin.

There are few written sources about falconry in the period before the Middle Ages, but already around year 1000 large amounts of art and literature began to emerge. Beyond being hunting birds the falcons were symbols of power, strength and superiority and found their place in coat of arms, banners and tapestries. The famous Bayeux tapestry is one of the best preserved contemporary sources. The first 10-15 meters of the embroidery is about a falcon hunt of Harold Godwinson's.

In the thirteenth century Frederick II of Hohenstaufen brought the sport to its highest state of respectability, when he wrote "The Art of Falconry". The book took over thirty years to complete, and as one of the first scientific works about birds placed him as one of the founders of ornithology. He introduced the Arabic practice of hooding falcons to keep them tranquil during training. His work also holds several pages of interesting instructions for dog trainers. The falcons often worked in conjunction with special trained hunting dogs, raised with the falcons since puppy hood. Frederick II's book is available for modern readers, newly edited and reprinted in 1969.

The position of falconer was usually handed down from father to son. In a royal household he was called Lord Falconer, sitting fourth from the king at table. He was responsible for capturing, training and caring for the hawks. He was a key number of the hunt, planning with the lord which birds to fly at which prey. He also rode to war with the lord, bringing the birds along to hunt for food.During the Hundred Year's War falcons accompanied their masters across the Channel to the battles of Grecy, Poitiers and Agincourt. When Edward III invaded France, he had thirty falconers with him. John of Gaunt often brought hunting parties to the Test Valley, and since it was due to the practice of ringing these birds, the huntings are documented in the Domesday Book.

Neither hawks or falcons are suitable house-pets because they have spectacular mode of excretion, they are tradionally kept on special perches standing in sand, the mews. Richard II let build the Royal Mews at Charing Cross in London, and the office of Master of the Mews is still extant.Falconry remained popular among royalty until the reign of George III. The Stuarts were particularly fond of the sport. Henry VIII was perhaps the most important falcon advocate since Frederick II. Mary, Queen of Scots, was an ardent fan of the merlins ("milady's falcon"), and Elizabeth, who liked the sport herself, occassionally let Mary out of the dungeon for short hawking excursions.

Falcons were so highly valued that they were worth more than their weight in gold. During one bloody crusade in the late fourteenth century, the Ottoman Sultan Beyazid captured the son of Philip the Bold, duke of Burgundy, and turned down Philip's offer of 200.000 gold ducats for ransom. Instead Beyazid wanted and was given something even more precious, twelve white gyrfalcons.

Falconry's popularity became a status symbol in medieval society, but it was a rather expensive pleasure. The birds required intricate housing and all kinds of accessories- and falconers were required to feed the birds a balanced diet on a daily basis. The average citizen kept more common birds like sparrowhawks and goshawks. According to the Boke of St. Albans of 1486, written by Dame Juliana Barnes, the prioress of Sopwell nunnery, there was a type of bird of prey for each class of feudal society. To keep a falcon that was above one's station was a felony, and the typical punishment was cutting off hands of people, who committed that crime.

People brought their pet falcon everywhere, perched on hand or wrist. Falcons were very popular among the clergy and were taken into religious services, especially nuns were rarely seen without their falcon on their wrist. Knights took their favourite birds to church so often that eventually rules were made to bar them. A few couples even got married with falcons on their fists. A lady was advised by her husband to take her bird everywhere with her so that it would become accustomed to people. Elements of the sport were found nearly everywhere. The Lisle Letters, published in six volumes by Muriel St. Claire Bryne, reveals how thoroughly falconry permeated various realities of life in the household of Lord and Lady Lisle.

In Shakespeare's works the reader will probably get a more distinct vision of falconry and the sporting pastimes of the aristocracy of that day than in any other way. To understand falconry and the falconer's words was an important part of the upbringing of young men and women, and it was often a necessity in order to understand the expressions in art and in some of Shakespeare's plays. In Shapespeare's time it was usual to go hunting in the afternoon, and when the falcon went up for the heron in a North Western wind, the falconer couldn't know the falcon from the heron, because he had the sun in his eyes. Therefore the words in Hamlet: " I am but mad north northwest, when the wind is southerly I know a hawk from a handsaw."

The Golden Age of falconry ended several centuries ago, due to the discovery of the firearms, but also because the feudal systems changed, and the forests were cleared for farmland.


Borrowed words:
The word codger, used today to describe an elderly person, can be traced back to the falconry term, cadger, who carried a portable perch called a cadge for a falconer. Most cadgers were old falconers.
Callow, which is a nestling raptor whose feathers are still in the blood-quill stage, is now used to describe someone who is young or untested.
When raptors drink , it is called bowsing. A bird that drinks heavily is called a boozer, the term used to describe the same tendency in humans.

The falcon's maximum speed:
Speed is the falcon's forte. If birds of prey were airplanes, then the eagles, the buzzards, the kites would be the gliders, and the falcons would be the jets. Estimates of the maximum speed of a falcon dive are as fast as 273 miles an hour (440 km/h) based on analysis of motion-picture footage of a falcon in full vertical dive taken by the Naval Research Laboratory in England in WWII. Most biologists, however, estimate the falcon's maximum velocity at 150 to 200 miles an hour ( 240 to 320 km/h), which is still faster than any other animal on earth.

Falconry in the Middle Ages II
by grethe bachmann

"Their haufdu Hauka sina a oxlom" (They had hawks on their shoulders) Rolf Krakes Saga Chapter XL:
Rolf Krake (6th century) and his men went on a visit to his hostile stepfather king Adils in Uppsala, and the saga says: "They had hawks on their shoulders, and this was considered a great splendour, and king Rolf owned the hawk named Höjbrog."
Hakon Jarl had to pay a yearly tax to Harald Bluetooth (d.985) of 10 mark in gold and 60 hunting falcons for that part of Norway that was transferred to him, and on account of this tax Harald Bluetooth used to call Norway his Haukei (hawk- or falcon island.)
Canute the Holy had in 1085 a seal made, showing him on horseback with a falcon upon his hand, and after his death in 1086 his mortal remains were swept in a Byzantine silken carpet with motifs of birds of prey.
Hakon the Old of Norway (1204-1263) was the first northern king, who made present of falcons to foreign sovereigns, thus a considerable amount of goshawks, and later Icelandic falcons were sent from Norway and Iceland to England. In 1276 Edward I received eight grey and three white gyrfalcons from the king of Norway as a sign of peace.

In the 14th century at least five shipments of falcons were sent to the Emperor of Morocco, and negotations concerning similar shipments to Tripoli were conducted by the Danish king.The Renaissance king Christian IV gave his brother in law, James the First of England and Scotland 24 falcons every year.
Finding new birds was an important endeavour in the Middle Ages. Falcons from Scandinavia were considered especially good birds. The gyrfalcon came in colours from grey in Scandinavia, especially Norway, to a lighter shade in Iceland and to and almost white with black markings in Greenland. Falcons from Iceland and Greenland were sent to the Royal mews in Norway and Denmark, and from here they were sold to a medieval company in Lübeck in northern Germany and then shipped across the Alps to Venice and thence to Alexandria, Baghdad and Constantinople.
The Icelandic gyrfalcon was already in 1100-1220 years exported to the courts in Europe. The resources for bringing falcons home from Iceland were rather troublesome, and the men had to travel several hundred kilometres along primitive roads. Many falcons died during these long travels in spite of the best care. Furthermore there had to be enough food for the falcons upon the ships on the way home. An account shows that 10 falcons for a period of 3 months eat 200 kilo meat, which had to be of the finest and leanest quality. Some falcons (ab.12-20%) were rejected in the end ot the journey, if they did not please the royal falconer. Most Icelandic falcons were given to foreign courts, only a few were kept by the Danish and Norwegian falconry.
Falcons were also captured in the open moors of Valkenswaard, Holland, where each year millions of migrant birds would stop on their way south, followed by the falcons. All during the Middle Ages falcons were trapped and trained here for the nobility of Europe. In the fall, knights and falconers from the courts of every feudal lord and king would gather for lively medieval auctions, bidding against one another for the best of the birds captured that year.
There are two main categories of birds used in falconry, long winged falcons, which hunt birds, and short winged hawks, (accipiters), which hunt a range of prey, often focusing on rabbits. In falconry the birds were divided by the type of bird and by the way they were flown at the prey. While short wings could be flown in wooded country, the long winged falcons required large open tracts, where the falconer could follow the flight with ease. The general rule was that true falcons were "hawks of the lure" and accipiters were "hawks of the fist".
The term hawking was used when a hawk was used for the hunting, and even the broader term austringer was used for a falconer, who hunted with hawks. The term falconry was used strictly for hunting with falcons. Short wings (goshawk, sparrow hawk) were not flown to the lure, but encouraged to make long flights at a rabbit lure pulled along the ground and encouraged to fly from tree to tree as the falconer walked along. If the hunt was not successful the bird returned to its place on the falconer's glove and waited for a new opportunity.
One of the characteristics of a true falcon is to prey on birds in the open air. They circle hundreds of feet into the air, waiting for the prey to be flushed out by beaters or dogs. In falconry only the larger female bird was properly called the falcon. The male, which is up to one third smaller than the female, was the tiercel. A male hawk is also one third smaller than the female, but never called tiercel.
The long winged falcons were restricted to nobility, and the gyrfalcon was considered the ultimate status symbol of the medieval potentates. It makes its home in the Arctic, and it prefers to take its prey in a low ground hugging attack. The gyrfalcon is the largest and noblest of the falcons, it's similar to the peregrine, but heavier and harder to train.
Peregrine Falcon

The most highly evolved of the falcons is the peregrine. It is a large falcon, but unlike the gyrfalcon the peregrine takes almost all of its prey out of the sky. The peregrine was a favourite of falconers and the most frequently bird used for falconry. It was not only easily trained, but provided the most daring spectacle. It circles high overhead, waiting for the quarry to be flushed, then dive for it at high speeds. In locations where the main quarry was wild fowl, it was sometimes called "hawk of the river". The peregrine was found all over Europe.
The saker was the banner bird of Attila the Hun, it feeds only on small mammals, usually taking its prey near the ground. Sakers were trained in Arabia to go after gazelles. They were the bird of choice of Arab falconers. Their breeding grounds were in Eastern Europe and the Middle East.
The lanners were used predominantly in France and Spain during the Middle Ages.

The hobby was considered the easiest falcon to train, it was mostly used for hunting larks. The merlin was "Milady's Falcon". It was considered the best flyer among the birds of prey and was sent after high flying skylarks. It circles up on a higher flying bird, until it is exhaused - and it doesn't mind chasing it through a tight flock of birds. Falconers recommended the kestrel for beginners, it was easy to train and handle and was used for hunting small birds like sparrows and larks.
Accipiters, (goshawks, sparrow hwawks) take birds too, but they do so in forests, where their short wings and long tails give them the ability to swerve through the branches, taking their prey by stealth and surprise. They waited upon the falconer's wrist or fist until the game was flushed, then were flown straight at the prey. They cannot fly as fast as the true falcons, but they can turn instantly and locate their quarry in dense vegetation.
The goshawk was considered the classic hunting bird, it was used for hunting pheasant, partridge, wild duck, hare and rabbit. Goshawk was everyman's hawk, as handy to the poacher as to the squire and required less skill than the peregrine. The austringer was not on horseback when hunting with goshawk. Its virtues were summed up in a nickname: kitchen-hawk. The French came to refer to goshawks as cuisiniers.
The female sparrow hawk was used for quail hunting.
The only difference between a trained and a wild falcon was that the falconer's bird had learned to accept the falconer as its helper. Falcons were taken from their nests as young birds and kept in mews or hawk houses. The falcon required much human contact and careful attention on daily basis, or else it would quickly grow wild an unreliable.
The falconer would feed the bird secretly, so it would not be aware that the food came from humans. The falcon was fed with its hood still on, until it ate without hesitation. Then gradually the hood was removed and the bird allowed to eat by candle light, as it slowly became accustomed to men, women, children and dogs.

Special devices aided the falconer. The falcons had small bells tied around their necks to help the falconer locate them, and they wore jesses, small leathered straps that hung loose, though they could later be attached to a leash. A leather hood covered the eyes of the bird to keep it calm.

Later the bird would be making long flights, and if it was absent at the regular feeding time, the falconer captured it back with nets. Training falcons required extreme patience and persistence, and the falconer was morally committed to keep his bird in good condition and to fly it regularly. Basically a hunting bird had to be tamed, or "manned". Raptors were not tamed in training, even birds bred for several generations in captivity were not tame in the way that social animals are.
The falconer was responsible for finding proper terrain with right wind conditions, plantations and proper quarry. When this was taken care of he was responsible for positioning himself, and if he had a dog, also the dog, in a way that left the bird in a position with the best chances possible of catching the quarry. Eventually the bird was taken into the field, where it was introduced to the lure, a padded weight with wings and with a long string attached. Food was tied to the lure and the falcon allowed to eat from it, until the bird associated the lure with food.
Birds were flown according to their weight and hunger. A fat bird might refuse to fly at all. The daily weighing of the bird was vital, and to ignore a bird's weight and condition was to lose it or kill it. The falconer manipulated the falcon's diet, so that the bird was in peak health, but just hungry enough to come to the falconer and the lure when called. A falconer must never take food away from the falcon. Once the bird killed its prey, the bird was taken from it with more food on the glove.
Before the hunting the bird was equipped with a hood, often decorated with tuft of feathers in the colours of the royal house. Hunting with falcons was usually done on horseback. The falconer wore his bird on his left glove hand. During the ride the falcon's breast had to be turned against the wind to prevent it from being restless. When the falconer saw the quarry, he threw the falcon up in the air, and if the bird caught eye of the game, it pursued it and went down on it in a vertical dive.
The horse was necessary for the falconer in order to move fast, and he had help from his dogs, who came to the falcon and its catch early. It all depended on the falcon itself, whether or not there would be any hunting. The falconer hurried to the spot and offered the falcon a piece of lean meat of partridge or something he knew his bird liked in change. It was essential that the falcon didn't feel cheated by the trade. If the bird found it was cheated it would fly away. Occassionally the falcon didn't start to eat the quarry, but awaited the approach of the falconer and the treasured morsel of lean meat.
Frederick II of Hohenstaufen said in his work about falconry that hunting for food put too great a burden on the falcon. He believed falconry was best practiced as an art, and he cautioned that a successful falconer could not be "indolent or careless, for this art requires much labor and much study". He advised the falconer to quiet a restless falcon with mouthfuls of pure cold water - after thouroughly having cleansed his mouth before the operation. Before Frederick II introduced the falcon hood, the birds' lower eyelids were stitched together with a fine silken thread, which was loosened gradually in the progress of the training.

The original purpose of falconry, using birds to capture quarry, was slowly replaced among the nobility by another purpose. The use of falconry was not a primary means of obtaining food for medieval citizens. Not even among nobility did falcons and hawks provide other than a small percent of meat. Falconry provided an opportunity for kings and lords to host other nobles for grand hunting parties. The kings of England and France, the Russian czars and the Holy Roman emperor all maintained extravagant falconry establishments. For the nobility falconry practiced on a magnificent scale became an essential element in establishing and maintaining personal and national prestige.
The patron of falconers St. Bavon is celebrated on October 1st. According to legend he was accused of stealing a white gyrfalcon, tried for the offence, and condemned to be executed. On the day and place of his execution the missing falcon suddenly appeared in the air and came down to land. St. Bavon's innocence, established by sign from heaven, caused him to be released immediately. He subsequently was regarded as the patron saint for falconers. He died in 659 and is buried in the cathedral in Gent.
