69-485: Founded 22 September 1962 by the Austrian zoologist Hans Psenner , Alpenzoo reintroduced endangered species like the bearded vulture , Alpine ibex , and northern bald ibis in the wild. The zoo is a non-profit association, and the majority of their funding comes from the entrance fees, but the zoo receives additional funds from the city of Innsbruck and the government of Tyrol. There is also financial participation from

138-400: A 62 cm (24 in) long monitor lizard . Larger animals have been known to be attacked by bearded vultures, including ibex , Capra goats , chamois , and steenbok . These animals have been killed by being surprised by the large birds and battered with wings until they fall off precipitous rocky edges to their deaths; although in some cases these may be accidental killings when both

207-515: A clutch of 1 to 2 eggs, though 3 have been recorded on rare occasions, which are incubated for 53 to 60 days. After hatching, the young spend 100 to 130 days in the nest before fledging . The young may be dependent on the parents for up to 2 years, forcing the parents to nest in alternate years on a regular basis. Typically, the bearded vulture nests in caves and on ledges and rock outcrops or caves on steep rock walls, so are very difficult for nest-predating mammals to access. Wild bearded vultures have

276-555: A concealed perch. In America , members of the Buteo group are also called hawks, though birds of this group are called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged and shorter-tailed than accipiters, and fly further distances in open areas. Buteos descend or pounce on their prey rather than engaging in fast, horizontal pursuit. The terms accipitrine hawk and buteonine hawk are used to distinguish between

345-535: A decrease in habitat space, fatal collisions with energy infrastructure, reduced food availability, poisons left out for carnivores and direct persecution in the form of trophy hunting. This species is currently listed as near threatened by the IUCN Red List last accessed on 1 October 2016, and the population continues to decline. Mitigation plans have been established to reduce the population declines in bearded vulture populations. One of these plans includes

414-423: A falcon-like cheek-acheek call made around the nest. The acid concentration in the bearded vulture's stomach has been estimated to be of pH about 1. Large bones are digested in about 24 hours, aided by slow mixing or churning of the stomach content. The high fat content of bone marrow makes the net energy value of bone almost as good as that of muscle, even if bone is less completely digested. A skeleton left on

483-441: A mating pair build their nest before mating season then improve it throughout nesting season. They usually do this before mating. Hawks have a striking mating ritual. First, a male and a female fly together in a circular motion . Once they reach a certain height, the male dives toward the female before ascending back to that height. The two birds repeat this until the male latches onto the female, and they begin to free-fall towards

552-470: A mean lifespan of 21.4 years, but have lived for up to at least 45 years in captivity. The bearded vulture is one of the most endangered European bird species as over the last century its abundance and breeding range have drastically declined. It naturally occurs at low densities, with anywhere from a dozen to 500 pairs now being found in each mountain range in Eurasia where the species breeds. The species

621-537: A medium size) by hammering them with their bill directly into rocks while perched. During the breeding season they feed mainly on carrion. They prefer the limbs of sheep and other small mammals and they carry the food to the nest, unlike other vultures which feed their young by regurgitation. Bearded vultures sometimes attack live prey, with perhaps greater regularity than any other vulture. Among these, tortoises seem to be especially favored depending on their local abundance. Tortoises preyed on may be nearly as heavy as

690-498: A method of measuring avian " IQ " by measuring their innovation in feeding habits. Based on this scale, hawks were named among the most intelligent birds. The hawk is very intelligent towards humans and other hawks. Hawks, like most birds, are tetrachromats with four types of colour receptors in the eye. Unlike some birds, but similar to other diurnal raptors, most hawk species are violet-sensitive but cannot perceive ultraviolet light. Hawks also have relatively high visual acuity –

759-646: A mountain will dehydrate and become protected from bacterial degradation, and the bearded vulture can return to consume the remainder of a carcass even months after the soft parts have been consumed by other animals, larvae, and bacteria. The bearded vulture is sparsely distributed across a vast range. It occurs in mountainous regions in the Pyrenees , the Alps , the Arabian Peninsula , the Caucasus region,

828-765: A rare visitor, bearded vultures occasionally travel to parts of the United Kingdom , with the first confirmed sighting taking place in 2016 in Wales and the Westcountry. A series of sightings took place in 2020, when an individual bird was sighted separately over the Channel Island of Alderney after migrating north through France, then in the Peak District , Derbyshire , Cambridgeshire , and Lincolnshire . The bird, nicknamed 'Vigo' by Tim Birch of

897-574: A separate minor lineage of Accipitridae together with the Egyptian vulture ( Neophron percnopterus ), its closest living relative. It is not much more closely related to the Old World vultures proper than to, for example, hawks , and differs from the former by its feathered neck. Although dissimilar, the Egyptian and bearded vulture each have a lozenge -shaped tail—unusual among birds of prey. It

966-473: Is 0.43±0.28 fledgings per breeding pair per year and the breeding success averaged 0.56±0.30 fledgings per pair with clutches/year. The nest is a massive pile of sticks, that goes from around 1 m (3 ft 3 in) across and 69 cm (27 in) deep when first constructed up to 2.5 m (8 ft 2 in) across and 1 m (3 ft 3 in) deep, with a covering of various animal matter from food, after repeated uses. The female usually lays

1035-568: Is a citizen scientist activity that monitors hawk migration and provides data to the scientific community. The red-tailed hawk is probably the most common hawk in North America . Past observations have indicated that, while hawks can easily adapt to most environments, they prefer open habitats such as deserts and fields, likely because it is easier to spot prey. As they are able to live anywhere, they can also be found in mountainous plains and tropical, moist areas such as Central America ,

1104-406: Is better for a hawk to arrive at its destination as early as possible to have first pick of mates, territory, food, and other resources. There are a variety of factors impacting the strategy and success of a hawk's migration. Kerlinger states that a bird has more body fat when it begins its migration than when it arrives at its destination. Thus, the more fat a bird has when it begins its migration,

1173-399: Is common at garbage dumps tips on the outskirts of small villages and towns. Although it occasionally descends to 300–600 m (980–1,970 ft), the bearded vulture is rare below an elevation of 1,000 m (3,300 ft) and normally resides above 2,000 m (6,600 ft) in some parts of its range. It typically lives around or above the tree line which are often near the tops of

1242-696: Is extinct in Romania , the last specimens from the Carpathians being shot in 1927. However, unconfirmed sightings of the bearded vulture happened in the 2000s, and in 2016 a specimen from a restoration project in France also flew over the country before returning to the Alps. In southern Africa, the total population as of 2010 was estimated at 408 adult birds and 224 young birds of all age classes therefore giving an estimate of about 632 birds. In Ethiopia , it

1311-407: Is highly nutritional for them compared to bones that are tinier. Smaller bones will contain less accessible bone marrow therefore being of less value. The bearded vulture has learned to crack bones too large to be swallowed by carrying them in flight to a height of 50–150 m (160–490 ft) above the ground and then dropping them onto rocks below, which smashes them into smaller pieces and exposes

1380-454: Is longer than the width of the wing. The tarsus is relatively small for the bird's size, at 8.8–10 cm (3.5–3.9 in). The proportions of the species have been compared to a falcon , scaled to an enormous size. Unlike most vultures, the bearded vulture does not have a bald head. This species is relatively small-headed, although its neck is powerful and thick. It has a generally elongated, slender shape, sometimes appearing bulkier due to

1449-963: Is most common in Ethiopia , where an estimated 1,400 to 2,200 are believed to breed. Relatively large, healthy numbers seem to occur in some parts of the Himalayas as well. It was largely wiped out in Europe and, by the beginning of the 20th century, the only substantial population was in the Spanish and French Pyrenees. Since then, it has been successfully reintroduced to the Swiss and Italian Alps, from where they have spread into France. They have also declined somewhat in parts of Asia and Africa, though less severely than in Europe. Many raptor species were shielded from anthropogenic influences in previously underdeveloped areas therefore they are greatly impacted as

1518-982: Is not an eagle. The common names of some birds include the term "hawk", reflecting traditional usage rather than taxonomy. For example, some people may call an osprey a " fish hawk " or a peregrine falcon a " duck hawk ". Falconry was once called "hawking", and any bird used for falconry could be referred to as a hawk. Aristotle listed eleven types of ἱέρακες ( hierakes , hawks; singular ἱέραξ , hierax ): aisalōn (merlin), asterias, hypotriorchēs, kirkos, leios, perkos, phassophonos, phrynologos, pternis, spizias, and triorchēs. Pliny numbered sixteen kinds of hawks, but named only aigithos, epileios, kenchrēïs (kestrel), kybindis, and triorchēs (buzzard). Accipitrine hawks generally hunt other birds as their primary prey and thus are sometimes called "hen-hawks". Similarly, they are sometimes called "wood-hawks" because of their woodland habitat .Though they are also known as "True Hawks" With most being called Sparrowhawks or Goshawks with

1587-567: Is now the only species placed in the genus Gypaetus that was introduced in 1784 by the German naturalist Gottlieb Storr . The genus name Gypaetus is from Ancient Greek gupaietos , a corrupt form of hupaietos meaning "eagle" or "vulture". The specific epithet barbatus is Latin meaning "bearded" (from barba , "beard"). The name "lammergeier" originates from the German word Lämmergeier , which means "lamb-vulture". The name stems from

1656-539: Is the only living bird species that specializes in feeding on bones. Meat and skin only makes up a small part of what the adults eat, but scraps of meat or skin makes up a larger amount of the chicks' diet. The bearded vulture can swallow whole or bite through brittle bones up to the size of a lamb's femur and its powerful digestive system quickly dissolves even large pieces. Their favored variants of bones to consume consist of fattier and elongated bones like tarsal bones and tibias. They contain more levels of oleic acid which

1725-415: Is thought to be cosmetic. This colouration comes from dust-bathing or rubbing iron-rich mud on its body. They also transfer the brown colour to the eggs. The tail feathers and wings are gray. The juvenile bird is dark black-brown over most of the body, with a buff-brown breast and takes five years to reach full maturity. The bearded vulture is silent, apart from shrill whistles in their breeding displays and

1794-521: Is traditionally included in Accipitridae, but is possibly a convergent genus from an unrelated group (see red goshawk taxonomy ). The " Buteonine group " includes genera Buteo , Parabuteo , Geranoetus , and most of Leucopternis . Members of this group have also been called "hawk-buzzards". The proposed new genera Morphnarchus , Rupornis , and Pseudastur would be formed from members of Buteo and Leucopternis . Members of

1863-717: Is used in politics to describe someone perceived as favoring war. The term reportedly originated in the United States during the 1810 debates in Congress over a possible war with Great Britain. Congressman John Randolph is said to have referred to Henry Clay 's pro-war faction as the "war-hawks". Numerous sporting clubs, such as the Atlanta Hawks , the Hawthorn Hawks , and the Malmö Redhawks , use

1932-647: Is usually ignored by these birds) or killed with beating wings by the vulture. When foraging for bones or live prey while in flight, bearded vultures fly fairly low over the rocky ground, staying around 2–4 m (6 ft 7 in – 13 ft 1 in) high. Occasionally, breeding pairs may forage and hunt together. In the Ethiopian Highlands , bearded vultures have adapted to living largely off human refuse. The bearded vulture occupies an enormous territory year-round. It may forage over 2 km (0.77 sq mi) each day. The breeding period

2001-520: Is variable, being December through September in Eurasia , November to June in the Indian subcontinent , October to May in Ethiopia , throughout the year in eastern Africa, and May to January in southern Africa. Although generally solitary, the bond between a breeding pair is often considerably close. Biparental monogamous care occurs in the bearded vulture. In a few cases, polyandry has been recorded in

2070-617: Is vernacularly known as Homa , a bird in Iranian mythology. The bearded vulture population is thought to be in decline; in 2004, it was classified on the IUCN Red List as least concern but has been listed as near threatened since 2014. It lives and breeds on crags in high mountains in Iran, southern Europe, East Africa, the Indian subcontinent , Tibet , and the Caucasus . Females lay one or two eggs in mid-winter that hatch at

2139-694: The Drakensberg in South Africa . It has been reintroduced in several places in Spain, such as the Sierras de Cazorla, Segura and Las Villas Jaén , the Province of Castellón and Asturias . The resident population as of 2018 was estimated at 1,200 to 1,500 individuals. In Israel it is locally extinct as a breeder since 1981, but young birds have been reported in 2000, 2004, and 2016. The species

2208-629: The West Indies , and Jamaica . Parents feed young hawks from early in their lives until they leave the nest. Young hawks, while still in the fledgling phase, will leave their nests as early as six weeks old, but they do not hunt until they are older. Like most birds of prey , hawks kill their prey with their talons. Hawks usually prefer hunting just before nightfall when daylight lessens. Although hawks are known for being violent predators , some are gentle and quiet. Hawks fly by flapping their wings rapidly then relying on momentum to glide through

2277-872: The Zagros Mountains , the Alborz ,Iran, the Koh-i-Baba in Bamyan , Afghanistan , the Altai Mountains , the Himalayas , Ladakh in northern India, and western and central China . In Africa, it lives in the Atlas Mountains , the Ethiopian Highlands and south from Sudan to northeastern Democratic Republic of the Congo , central Kenya , and northern Tanzania . An isolated population inhabits

2346-518: The " Buteogallus group" are also called hawks, with the exception of solitary eagle species. Buteo is the type genus of the subfamily Buteoninae. This subfamily traditionally includes eagles and sea-eagles, but Lerner and Mindell (2005) proposed placing them into separate the subfamilies Aquilinae and Haliaaetinae. This would leave only the buteonine hawks/buzzards in Buteoninae. In February 2005, Canadian ornithologist Louis Lefebvre announced

2415-520: The "bearded vulture" that had been described and illustrated in 1750 by the English naturalist George Edwards . Edwards had based his hand-coloured etching on a specimen that had been collected at Santa Cruz near the town of Oran in Algeria. Linnaeus specified the type locality as Africa, but in 1914 this was restricted to Santa Cruz by the German orthithologist Ernst Hartert . The bearded vulture

2484-582: The Conservation of the Bearded Vulture ( Spanish : Fundación para la Conservación del Quebrantahuesos ), established in Spain in 1995, was created in response to the national population dropping to 30 specimens by the end of the 20th century. Focused on conserving the species in the Pyrenees , it also returned the species to other already extinct areas such as the Picos de Europa in the north of

2553-506: The Derbyshire Wildlife Trust, is believed to have originated from the reintroduced population in the Alps. The bearded vulture is a scavenger , feeding mostly on the remains of dead animals . Its diet comprises mammals (93%), birds (6%) and reptiles (1%), with medium-sized ungulates forming a large part of the diet. It usually disdains the actual meat and typically lives on 85–90% bones including bone marrow . This

Flocks of birds, especially hawks, are sometimes called "kettles" in the United States. Hawks are known for their unique mating season and means of reproduction . Some species of hawk are monogamous and have one partner their whole lives. The male and female of

There are two restaurants on site: the ANIMAHL - Bistro im Zoo, offering daily dishes and a fine selection of beverage, and the Café and Restaurant "Weiherburg", for a more casual experience. Both offer indoor and outdoor seating. There is a both a big playground and a smaller one for little children. There is also a climbing wall that leads to

2967-462: The beginning of spring. The bearded vulture is the only known vertebrate whose diet consists of 70–90% bone. The bearded vulture was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae . He placed it with the vultures and condors in the genus Vultur and coined the binomial name Vultur barbatus . Linnaeus based his account on

3036-435: The belief that it attacked lambs. Two subspecies are recognised: This bearded vulture is 94–125 cm (37–49 in) long with a wingspan of 2.31–2.83 m (7 ft 7 in – 9 ft 3 in). It weighs 4.5–7.8 kg (9.9–17.2 lb), with the nominate race averaging 6.21 kg (13.7 lb) and G. b. meridionalis of Africa averaging 5.7 kg (13 lb). In Eurasia, vultures found around

3105-546: The better its chances of making the trip safely. Flight path is another important factor in migration because a bird's route can greatly affect the conditions it encounters during its journey. For example, wind direction and speed can either throw the bird off course or push it in the right direction. Due to the relative variability of air conditions over large bodies of water and the resulting impact on safety, hawks tend to avoid any large bodies of water while migrating by detouring around lakes or flying along coasts. Hawkwatching

3174-616: The big feature of the zoo, with some species rarely seen in zoos like the northern bald ibises that can be observed in a big aviary that was built specifically to accommodate the endangered birds. There is also the Innergschlöß where many species can be seen, like the bearded vulture. The zoo also has a little show farm to show the diversity of the Alpine livestock. Many species of fowls, sheep, cattle, pigs and goats can be observed and petted. A lot of these breeds are old breeds created to meet

3243-782: The birds forbidden to be eaten ( Leviticus 11:13). In 1944, Shimon Peres and David Ben-Gurion found a nest of bearded vultures in the Negev desert. The bird is called peres in Hebrew , and Shimon Persky liked it so much he adopted it as his surname . Hawk Hawks are birds of prey of the family Accipitridae . They are very widely distributed and are found on all continents except Antarctica. The subfamily Accipitrinae includes goshawks , sparrowhawks , sharp-shinned hawks , and others. This subfamily are mainly woodland birds with short broad wings, long tails, and high visual acuity. They hunt by dashing suddenly from

3312-471: The birds learned to fly and were able to reach food without human assistance. This method has proven more successful, with over 200 birds released in the Alps from 1987 to 2015, and a bearded vulture population has reestablished itself in the Alps. The bearded vulture is considered a threatened species in Iran . Iranian mythology considers the rare bearded vulture ( Persian : هما ; lit.   ' Homa ' )

3381-483: The both being named such because of them hunting small birds (like sparrow) and large water-fowl (like goose) respectively The subfamily Accipitrinae contains the genus Accipiter as well as the genera Micronisus (Gabar goshawk), Urotriorchis (long-tailed hawk), and Megatriorchis (Doria's goshawk). Melierax (chanting goshawk) may be included in the subfamily or given a subfamily of its own. Erythrotriorchis (red- and chestnut-shouldered goshawk)

3450-676: The country or the Sierra de Cazorla , in the south. After 25 years of work, the Foundation reported that they had managed to recover the species, with more than 1,000 specimens throughout the country. Efforts to reintroduce the bearded vulture began in the 1970s in the French Alps . Zoologists Paul Geroudet and Gilbert Amigues attempted to release vultures that had been captured in Afghanistan, but this approach proved unsuccessful: it

3519-516: The distance at which they can resolve an image – with red-tailed hawks reported to have 16.8 cycles per degree. This is due to the large number of photoreceptors in the retina (up to 1,000,000 per square mm in Buteo , compared to 200,000 in humans ), a high number of nerves connecting these receptors to the brain, and an indented fovea , which magnifies the central portion of the visual field . Hawks additionally have two foveae (depressions in

3588-458: The few species of birds that could yield valid signs to these soothsayers. The Greek playwright Aeschylus was said to have been killed in 456 or 455 BC by a tortoise dropped by an eagle who mistook his bald head for a stone—if this incident did occur, the bearded vulture is a likely candidate for the "eagle" in this story. In the Bible / Torah , the bearded vulture, as the ossifrage, is among

3657-509: The fish species present in the Alps. The Alpenzoo is the only zoo in the world that exhibits the wallcreeper . Here are a few of the species of birds, mammals, reptiles and amphibians exhibit at the Alpenzoo: The zoo is on the slope of a mountain, with lots of footpaths to explore the park and observe the animals. The main attraction of the zoo are the big Alpine animals: bears, wolves, moose, bison, etc. Birds of prey are also one of

3726-478: The form of a snail. The Alpenzoo was one of the places chosen to represent Austria on the collectible zero Euro bank note. The picture represents three of the zoo's star animals: the bearded vulture, the lynx and the Alpine ibex. The zoo accommodates about 2000 animals from 150 animal species: 20 mammals (of the 80 mammal species in the Alps), 60 bird species, 11 reptile species and 6 amphibian species, plus almost all

3795-514: The ground. In one year, a female hawk will lay about five eggs. Both the male and the female guard and care for the eggs for about a month until they hatch. Hawks feed on a variety of smaller animals such as snakes , lizards , fish , mice , rabbits , squirrels , birds , or any other type of small game that is found on the ground. As an example, red-shouldered hawks eat smaller birds like doves as well as bugs like grasshoppers and crickets . The term war hawk , or simply hawk ,

3864-488: The human population rises and infrastructure increases in underdeveloped areas. The increase in human population and infrastructure results in the declines of the bearded vulture populations today. The increase of infrastructure includes the building of houses, roads, and power lines. A major issue with infrastructure and bird species populations is collision with power lines. The declines of the bearded vulture populations have been documented throughout their range resulting from

3933-484: The mountains, at up to 2,000 m (6,600 ft) in Europe, 4,500 m (14,800 ft) in Africa and 5,000 m (16,000 ft) in central Asia. In southern Armenia, it breeds below 1,000 m (3,300 ft) if cliff availability permits. It has even been observed living at elevations of 7,500 m (24,600 ft) in the Himalayas and been observed flying at a height of 7,300 m (24,000 ft). Though

4002-584: The nutritious marrow. They can fly with bones up to 10 cm (3.9 in) in diameter and weighing over 4 kg (8.8 lb), or nearly equal to their own weight. After dropping the large bones, the bearded vulture spirals or glides down to inspect them and may repeat the act if the bone is not sufficiently cracked. This learned skill requires extensive practice by immature birds and takes up to seven years to master. Its old name of ossifrage ("bone breaker") relates to this habit. Less frequently, these birds have been observed trying to break bones (usually of

4071-493: The often hunched back of these birds. The gait on the ground is waddling and the feet are large and powerful. The adult is mostly dark gray, rusty, and whitish in color. It is grey-blue to grey-black above. The creamy-coloured forehead contrasts against a black band across the eyes and lores and bristles under the chin, which form a black beard that give the species its English name. Bearded vultures are variably orange or rust of plumage on their head, breast, and leg feathers, but this

4140-403: The preying vulture. To kill tortoises, bearded vultures fly with them to some height and drop them to crack open the bulky reptiles' hard shells. Golden eagles have been observed to kill tortoises in the same way. Other live animals, up to nearly their own size, have been observed to be predaceously seized and dropped in flight. Among these are rock hyraxes , hares , marmots and, in one case,

Finally, the eyeball is elongated, placing the lens far from the retina and giving a long focal length . Like most birds, hawks migrate in the autumn and the spring. The autumn migration season begins in August and ends mid-December, and different types of hawk choose different times in each season to migrate. Some migration distances are longer than others, and birds traveling longer distances tend to depart in early autumn while those traveling shorter distances start much later. Studies have shown that it

The zoo also received international recognition for its breeding program of some rare Alpine fish species. The Alpenzoo has an educational department that offers experimental teaching with animals for groups of all ages. The professional hire to teach are both teachers and biologists. Most of

4416-411: The species. The territorial and breeding display between bearded vultures is often spectacular, involving the showing of talons, tumbling, and spiraling while in solo flight. The large birds also regularly lock feet with each other and fall some distance through the sky with each other. In Europe, the breeding pairs of bearded vultures are estimated to be 120. The mean productivity of the bearded vulture

There are also six big terrarium created to accommodate the reptiles species of the zoo, and an aqua-terrarium to cater for the amphibians. With its 17 tanks containing between 80 and 14,000 liters each, the Alpenzoo owns the biggest fresh water aquarium in the world. More than 50 species of Alpine fishes can be observed there, with some of

4554-577: The symbol of luck and happiness. It was believed that if the shadow of a Homa fell on one, he would rise to sovereignty and anyone shooting the bird would die in forty days. The habit of eating bones and apparently not killing living animals was noted by Sa'di in Gulistan , written in 1258, and Emperor Jahangir had a bird's crop examined in 1625 to find that it was filled with bones. The ancient Greeks used ornithomancers to guide their political decisions: bearded vultures, or ossifrage, were one of

4623-426: The types in regions where hawk applies to both. The term "true hawk" is sometimes used for the accipitrine hawks in regions where buzzard is preferred for the buteonine hawks. All these groups are members of the family Accipitridae , which includes hawks and buzzards as well as kites , harriers , and eagles . To confuse things further, some authors use "hawk" generally for any small to medium Accipitrid that

4692-546: The vulture and the mammal surprise each other. Many large animals killed by bearded vultures are unsteady young, or have appeared sickly or obviously injured. Humans have been anecdotally reported to have been killed in the same way.
