The Springvale Aggregation was created when Springvale was purchased along with Alice Downs , Mabel Downs, and Texas Downs by

144-701: A South African company in 2003. As of March 2022 the four properties are owned by Harvest Road , an agribusiness owned by Andrew Forrest . Springvale Station is situated about 48 kilometres (30 mi) north of Halls Creek and 84 kilometres (52 mi) south west of Warmun in the Kimberley region. The cluster of stations known as Springvale Aggregation covers 604,430 ha (1,493,600 acres). J. W. McAdam acquired Springvale in 1932 from E. Bridge and Sons. The family business Quilty and Sons acquired Springvale in 1948 from W. J. McAdam in 1948. The Quiltys already owned neighbouring Bedford Downs Station . In 2003

216-547: A ball for the traditional football game of marngrook . In addition, there were important Dreaming stories and ceremonies involving the kangaroo. Aherrenge is a current kangaroo dreaming site in the Northern Territory . Unlike many of the smaller macropods, kangaroos have fared well since European settlement . European settlers cut down forests to create vast grasslands for sheep and cattle grazing, added stock watering points in arid areas, and have substantially reduced

288-516: A farmer's life by alerting family members to his location when he was injured by a falling tree branch. She received the RSPCA Australia National Animal Valour Award on 19 May 2004. There are very few records of kangaroos attacking humans without provocation; however, several such unprovoked attacks in 2004 spurred fears of a rabies -like disease possibly affecting the marsupials. Only two reliably documented cases of

360-657: A fatality from a kangaroo attack have occurred in Australia. The first attack occurred in New South Wales in 1936 when a hunter was killed as he tried to rescue his two dogs from a heated fray. The second attack was inflicted on a 77-year-old man from a domesticated kangaroo in Redmond, Western Australia in September 2022. Other suggested causes for erratic and dangerous kangaroo behaviour include extreme thirst and hunger. In July 2011,

432-561: A female is the victim of a collision, animal welfare groups ask that her pouch be checked for any surviving joey, in which case it may be removed to a wildlife sanctuary or veterinary surgeon for rehabilitation . Likewise, when an adult kangaroo is injured in a collision, a vet , the RSPCA Australia or the National Parks and Wildlife Service can be consulted for instructions on proper care. In New South Wales, rehabilitation of kangaroos

504-582: A golden kangaroo in a green triangle to show that a product is grown or made in Australia. Registered trademarks of early Australian companies using the kangaroo included Yung, Schollenberger & Co. Walla Walla Brand leather and skins (1890); Arnold V. Henn (1892) whose emblem showed a family of kangaroos playing with a skipping rope ; Robert Lascelles & Co. linked the speed of the animal with its velocipedes (1896); while some overseas manufacturers, like that of "The Kangaroo" safety matches (made in Japan) of

576-607: A group. The kangaroo performing the sniffing gains much information from smell cues. This behavior enforces social cohesion without consequent aggression. During mutual sniffing, if one kangaroo is smaller, it will hold its body closer to the ground and its head will quiver, which serves as a possible form of submission. Greetings between males and females are common, with larger males being the most involved in meeting females. Most other non-antagonistic behavior occurs between mothers and their young. Mother and young reinforce their bond through grooming. A mother will groom her young while it

648-475: A kangaroo is no higher than that of a similarly sized quadruped, and the Australian native predators are in any case less fearsome than those of other countries—but economy: in an infertile country with highly variable weather patterns, the ability of a kangaroo to travel long distances at moderately high speed in search of food sources is crucial to survival. New research has revealed that a kangaroo's tail acts as

720-428: A male red kangaroo attacked a 94-year-old woman in her own backyard as well as her son and two police officers responding to the situation. The kangaroo was capsicum sprayed (pepper sprayed) and later put down after the attack. Kangaroos—even those that are not domesticated— can communicate with humans, according to a research study. Nine out of ten animal collisions in Australia involve kangaroos. A collision with

792-507: A region which has few opportunities. In addition, with Forrest's known interest in improving the lives of Indigenous peoples, it is hoped that his wealth could be used to improve educational outcomes for children in the Halls Creek area. Pastoral lease In the Australian states and territories , leases constitute a land apportionment system created in the mid-19th century to facilitate

864-417: A small head. Like most marsupials, female kangaroos have a pouch called a marsupium in which joeys complete postnatal development. Because of its grazing habits, the kangaroo has developed specialized teeth that are rare among mammals. Its incisors are able to crop grass close to the ground and its molars chop and grind the grass. Since the two sides of the lower jaw are not joined or fused together,

936-439: A small quantity of yolk within it) descends from the ovary into the uterus . There it is fertilised and quickly develops into a neonate . Even in the largest kangaroo species (the red kangaroo ), the neonate emerges after only 33 days. Usually, only one young is born at a time. It is blind, hairless, and only a few centimetres long; its hindlegs are mere stumps; it instead uses its more developed forelegs to climb its way through

1008-458: A source of food for indigenous Australians for tens of thousands of years. Kangaroo meat is high in protein and low in fat (about 2%). Kangaroo meat has a high concentration of conjugated linoleic acid (CLA) compared with other foods, and is a rich source of vitamins and minerals. Low fat diets rich in CLA have been studied for their potential in reducing obesity and atherosclerosis. Kangaroo meat

1080-400: A speed of 40 km/h (25 mph) for nearly 2 km (1.2 mi). During a hop, the powerful gastrocnemius muscles lift the body off the ground while the smaller plantaris muscle , which attaches near the large fourth toe, is used for push-off. Seventy percent of potential energy is stored in the elastic tendons. At slow speeds, it employs pentapedal locomotion, using its tail to form

1152-399: A third leg rather than just a balancing strut. Kangaroos have a unique three-stage walk where they plant their front legs and tail first, then push off their tail, followed lastly by the back legs. The propulsive force of the tail is equal to that of both the front and hind legs combined and performs as much work as what a human leg walking can at the same speed. A DNA sequencing project of

1224-488: A tripod with its two forelimbs while bringing its hind feet forward. Both pentapedal walking and fast hopping are energetically costly. Hopping at moderate speeds is the most energy efficient, and a kangaroo moving above 15 km/h (9.3 mph) maintains energy consistency more than similarly sized animals running at the same speed. Kangaroos have single-chambered stomachs quite unlike those of cattle and sheep , which have four compartments. They sometimes regurgitate

1296-405: A vehicle is capable of killing a kangaroo. Kangaroos dazzled by headlights or startled by engine noise often leap in front of cars. Since kangaroos in mid-bound can reach speeds of around 50 km/h (31 mph) and are relatively heavy, the force of impact can be severe. Small vehicles may be destroyed, while larger vehicles may suffer engine damage. The risk of harm or death to vehicle occupants

1368-399: Is carried out by volunteers from WIRES . Council road signs often list phone numbers for callers to report injured animals. The kangaroo is a recognisable symbol of Australia. The kangaroo and emu feature on the Australian coat of arms . Kangaroos have also been featured on coins, most notably the five kangaroos on the Australian one dollar coin . The Australian Made logo consists of

1440-451: Is greatly increased if the windscreen is the point of impact. As a result, "kangaroo crossing" signs are commonplace in Australia. Vehicles that frequent isolated roads, where roadside assistance may be scarce, are often fitted with " roo bars " to minimise damage caused by collision. Bonnet -mounted devices, designed to scare wildlife off the road with ultrasound and other methods, have been devised and marketed, but are ineffective. If

1512-476: Is instead converted into acetate , which is then used to provide further energy. Scientists are interested in the possibility of transferring the bacteria responsible for this process from kangaroos to cattle, since the greenhouse gas effect of methane is 23 times greater than carbon dioxide per molecule. Groups of kangaroos are called mobs , courts or troupes , which usually have 10 or more kangaroos in them. Living in mobs can provide protection for some of

1584-419: Is known as embryonic diapause , and will occur in times of drought and in areas with poor food sources. Meanwhile, the neonate in the pouch grows rapidly. After about 190 days, the baby ( joey ) is sufficiently large and developed to make its full emergence out of the pouch, after sticking its head out for a few weeks until it eventually feels safe enough to fully emerge. From then on, it spends increasing time in

1656-400: Is largely done by males. Smaller males fight more often near females in oestrus, while the large males in consorts do not seem to get involved. Ritualised fights can arise suddenly when males are grazing together. However, most fights are preceded by two males scratching and grooming each other. One or both of them will adopt a high standing posture, with one male issuing a challenge by grasping

1728-400: Is no forearm locking. The losing combatant seems to use kicking more often, perhaps to parry the thrusts of the eventual winner. A winner is decided when a kangaroo breaks off the fight and retreats. Winners are able to push their opponents backwards or down to the ground. They also seem to grasp their opponents when they break contact and push them away. The initiators of the fights are usually

1800-505: Is now extinct . Other extinct predators included the marsupial lion , Megalania and Wonambi . However, with the arrival of humans in Australia at least 50,000 years ago and the introduction of the dingo about 5,000 years ago, kangaroos have had to adapt. Along with dingoes, introduced species such as foxes, feral cats , and both domestic and feral dogs, pose a threat to kangaroo populations. Kangaroos and wallabies are adept swimmers , and often flee into waterways if presented with

1872-467: Is rare but not new among kangaroos. The first official report of kangaroo blindness took place in 1994, in central New South Wales . The following year, reports of blind kangaroos appeared in Victoria and South Australia. By 1996, the disease had spread "across the desert to Western Australia". Australian authorities were concerned the disease could spread to other livestock and possibly humans. Researchers at

1944-497: Is suckling or after it is finished suckling. A joey will nuzzle its mother's pouch if it wants access to it. Sexual activity of kangaroos consists of consort pairs. Oestrous females roam widely and attract the attention of males with conspicuous signals. A male will monitor a female and follow her every movement. He sniffs her urine to see if she is in oestrus, a process exhibiting the flehmen response . The male will then proceed to approach her slowly to avoid alarming her. If

2016-553: Is used as a logo for some of Australia's most well-known organisations, such as Qantas , and as the roundel of the Royal Australian Air Force . The kangaroo is important to both Australian culture and the national image, and consequently there are numerous popular culture references . Wild kangaroos are shot for meat, leather hides , and to protect grazing land. Kangaroo meat has perceived health benefits for human consumption compared with traditional meats due to

2088-653: The Australian national rugby league team (the Kangaroos) and the Australian national rugby union team (the Wallabies). In a nation-wide competition held in 1978 for the XII Commonwealth Games by the Games Australia Foundation Limited in 1982, Hugh Edwards' design was chosen; a simplified form of six thick stripes arranged in pairs extending from along the edges of a triangular centre represent both

2160-809: The genome of a member of the kangaroo family, the tammar wallaby , was started in 2004. It was a collaboration between Australia (mainly funded by the State of Victoria ) and the National Institutes of Health in the US. The tammar's genome was fully sequenced in 2011. The genome of a marsupial such as the kangaroo is of great interest to scientists studying comparative genomics , because marsupials are at an ideal degree of evolutionary divergence from humans: mice are too close and have not developed many different functions, while birds are genetically too remote. The dairy industry could also benefit from this project. Eye disease

2232-421: The tree-kangaroos , another type of macropod, which inhabit the tropical rainforests of New Guinea , far northeastern Queensland and some of the islands in the region. This kind of kangaroo lives in the upper branches of trees. A general idea of the relative size of these informal terms could be: Kangaroos have large, powerful hind legs , large feet adapted for leaping, a long muscular tail for balance, and

2304-432: The 1,344-square-kilometre (519 sq mi) property was sold as part of a A$ 15-million four-property deal to South African interests. The four adjoining stations of Springvale, Bedford Downs , Mabel Downs and Alice Downs comprised an area of 5,850 square kilometres (2,259 sq mi) and were stocked with approximately 32,000 head of cattle. In March 2022, Andrew Forrest 's agribusiness, Harvest Road , bought

2376-586: The Australian Animal Health Laboratories in Geelong detected a virus called the Wallal virus in two species of midges , believed to have been the carriers. Veterinarians also discovered fewer than 3% of kangaroos exposed to the virus developed blindness. Kangaroo reproduction is similar to that of opossums . The egg (still contained in the shell membrane, a few micrometres thick, and with only

2448-468: The ancestors of kangaroos. while others hold the contrary view. The middle to late bulungamayines, Ganguroo and Wanburoo lacked digit 1 of the hind foot and digits 2 and 3 were reduced and partly under the large digit 4, much like the modern kangaroo foot. This would indicate that they were bipedal. In addition, their ankle bones had an articulation that would have prohibited much lateral movements, an adaptation for bipedal hopping. Species related to

2520-481: The area when they happened upon the animal. They asked a nearby local what the creatures were called. The local responded "kangaroo", said to mean "I don't know/understand", which Cook then took to be the name of the creature. Anthropologist Walter Roth was trying to correct this legend as far back as in 1898, but few took note until 1972 when linguist John B. Haviland in his research with the Guugu Yimithirr people

2592-505: The commercial harvest areas of Australia in 2019, down from 53.2 million in 2013. As with the terms " wallaroo " and " wallaby ", "kangaroo" refers to a paraphyletic grouping of species. All three terms refer to members of the same taxonomic family, Macropodidae, and are distinguished according to size. The largest species in the family are called "kangaroos" and the smallest are generally called "wallabies". The term "wallaroos" refers to species of an intermediate size. There are also

2664-416: The development of an embryo until the previous joey is able to leave the pouch. This is known as embryonic diapause and will occur in times of drought and in areas with poor food sources. The composition of the milk produced by the mother varies according to the needs of the joey. In addition, the mother is able to produce two different kinds of milk simultaneously for the newborn and the older joey still in

2736-594: The early 1900s, also adopted the symbol. Even today, Australia's national airline, Qantas , uses a bounding kangaroo for its logo. The kangaroo appears in Rudyard Kipling 's Just So Stories , " The Sing-Song of Old Man Kangaroo ", while the kangaroo is chased by a dingo, he gives Nqong the Big God's advice, that his legs and tail grew longest before five o'clock. The kangaroo and wallaby feature predominantly in Australian sports teams names and mascots. Examples include

2808-485: The family. The term wallaby is an informal designation generally used for any macropod that is smaller than a kangaroo or a wallaroo that has not been designated otherwise. Kangaroos are the only large mammals to use hopping on two legs as their primary means of locomotion . The comfortable hopping speed for a red kangaroo is about 20–25 km/h (12–16 mph), but speeds of up to 70 km/h (43 mph) can be attained over short distances, while it can sustain

2880-599: The female does not run away, the male will continue by licking, pawing, and scratching her, and copulation will follow. After copulation is over, the male will move on to another female. Consort pairing may take several days and the copulation is also long. Thus, a consort pair is likely to attract the attention of a rival male. As larger males are tending bonds with females near oestrus, smaller males will tend to females that are farther from oestrus. Dominant males can avoid having to sort through females to determine their reproductive status by searching for tending bonds held by

2952-457: The joey is born, it is about the size of a lima bean . The joey will usually stay in the pouch for about 9 months (180–320 days for the Western Grey) before starting to leave the pouch for small periods of time. It is usually fed by its mother until reaching 18 months. The female kangaroo is usually pregnant in permanence, except on the day she gives birth; however, she has the ability to freeze

3024-527: The kangaroo in full flight, and a stylised "A" for Australia. Kangaroos are well represented in films, television, books, toys and souvenirs around the world. Skippy the Bush Kangaroo was a popular 1960s Australian children's television series about a fictional pet kangaroo. Kangaroos are featured in the Rolf Harris song " Tie Me Kangaroo Down, Sport " and several Christmas carols. The kangaroo has been

3096-399: The largest male they can displace without a fight. Fighting has been described in all species of kangaroos. Fights between kangaroos can be brief or long and ritualised. In highly competitive situations, such as males fighting for access to oestrous females or at limited drinking spots, the fights are brief. Both sexes will fight for drinking spots, but long, ritualised fighting or "boxing"

3168-467: The lease has: Kangaroo Kangaroos are marsupials from the family Macropodidae (macropods, meaning "large foot"). In common use the term is used to describe the largest species from this family, the red kangaroo , as well as the antilopine kangaroo , eastern grey kangaroo , and western grey kangaroo . Kangaroos are indigenous to Australia and New Guinea . The Australian government estimates that 42.8 million kangaroos lived within

3240-526: The leaseholder and the affected native title group. Australian jurisdictions have land management legislation that affects the administration of pastoral leases. As of November 2023 the legislation and management arrangements are as follows: The statutory provisions of pastoral leases are covered by the New Zealand Crown Pastoral Land Act 1998 and the Land Act 1948 . The holder of

3312-419: The leases falls mainly to state and territory governments. Leases within state jurisdictions have variations as to applicability from state to state. Under Commonwealth of Australia law, applicable only in the Northern Territory , they are agreements that allow for the use of Crown land by farmers. Native title can co-exist with pastoral leases, and Indigenous land use agreements may be made between

3384-529: The low level of fat on kangaroos. The word kangaroo derives from the Guugu Yimithirr word gangurru , referring to eastern grey kangaroos . The name was first recorded as "kanguru" on 12 July 1770 in an entry in the diary of Sir Joseph Banks ; this occurred at the site of modern Cooktown , on the banks of the Endeavour River , where HMS  Endeavour under the command of Lieutenant James Cook

3456-563: The low quality grass diet with the development of foregut fermentation . The most numerous early macropods, the Balbaridae and the Bulungamayinae , became extinct in the Late Miocene around 5–10 mya. There is dispute over the relationships of the two groups to modern kangaroos and rat-kangaroos . Some argue that the balbarines were the ancestors of rat-kangaroos and the bulungamayines were

3528-436: The lower incisors are farther apart, giving the kangaroo a wider bite. The silica in grass is abrasive, so kangaroo molars are ground down and they actually move forward in the mouth before they eventually fall out, and are replaced by new teeth that grow in the back. This process is known as polyphyodonty and, amongst other mammals, only occurs in elephants and manatees . The large kangaroos have adapted much better than

3600-436: The lungs, providing further energy efficiency. Studies of kangaroos and wallabies have demonstrated, beyond the minimum energy expenditure required to hop at all, increased speed requires very little extra effort (much less than the same speed increase in, say, a horse, dog or human), and the extra energy is required to carry extra weight. For kangaroos, the key benefit of hopping is not speed to escape predators—the top speed of

3672-662: The modern grey kangaroos and wallaroos begin to appear in the Pliocene. The red kangaroo appears to be the most recently evolved kangaroo, with its fossil record not going back beyond the Pleistocene era, 1–2 mya. The first kangaroo to be exhibited in the Western world was an example shot by John Gore , an officer on Captain Cook's ship, HMS Endeavour , in 1770. The animal was shot and its skin and skull transported back to England whereupon it

3744-571: The number of dingoes. This overabundance has led to the view that the kangaroo is a pest animal as well as requiring regular culling and other forms of management. There is concern that the current management practices are leading to detrimental consequences for kangaroo welfare, landscape sustainability, biodiversity conservation, resilient agricultural production and Aboriginal health and culture. Kangaroos are shy and retiring by nature, and in normal circumstances present no threat to humans. In 2003, Lulu, an eastern grey which had been hand-reared, saved

3816-406: The option. If pursued into the water, a large kangaroo may use its forepaws to hold the predator underwater so as to drown it. Another defensive tactic described by witnesses is catching the attacking dog with the forepaws and disembowelling it with the hind legs. Kangaroos have developed a number of adaptations to a dry, infertile country and highly variable climate. As with all marsupials ,

3888-691: The orderly division and sale of land to European colonists. Legislation ensured that certain Aboriginal rights were embodied in pastoral leases. However, according to historian Henry Reynolds , several colonial leaders ran roughshod over these rights, including Sir John Downer (when the Northern Territory was governed by the colonial government of South Australia ); Sir John Forrest in the colony of Western Australia ; and Sir Samuel Griffith in Queensland . Pastoral leases exist in both Australian commonwealth law and state jurisdictions. They do not give all

3960-423: The other male's neck with its forepaw. Sometimes, the challenge will be declined. Large males often reject challenges by smaller males. During fighting, the combatants adopt a high standing posture and paw at each other's heads, shoulders and chests. They will also lock forearms and wrestle and push each other as well as balance on their tails to kick each other in the abdomen. Brief fights are similar, except there

4032-564: The outside world and eventually, after about 235 days, it leaves the pouch for the last time. The lifespan of kangaroos averages at six years in the wild to in excess of 20 years in captivity, varying by the species. Most individuals, however, do not reach maturity in the wild. The kangaroo has always been a very important animal for Aboriginal Australians , for its meat , hide, bone, and tendon . Kangaroo hides were also sometimes used for recreation; in particular there are accounts of some tribes ( Kurnai ) using stuffed kangaroo scrotum as

4104-405: The pouch. Unusually, during a dry period, males will not produce sperm and females will conceive only if enough rain has fallen to produce a large quantity of green vegetation. Kangaroos and wallabies have large, elastic tendons in their hind legs. They store elastic strain energy in the tendons of their large hind legs, providing most of the energy required for each hop by the spring action of

4176-552: The red kangaroo include significant amounts of shrubs in their diets. Smaller species of kangaroos also consume hypogeal fungi. Many species are nocturnal , and crepuscular , usually spending the hot days resting in shade, and the cool evenings, nights and mornings moving about and feeding. Despite having herbivorous diets similar to ruminants such as cattle, which release large quantities of digestive methane through exhaling and eructation (burping), kangaroos release virtually none. The hydrogen byproduct of fermentation

4248-552: The rights that attach to freehold land: there are usually conditions which include a time period and the type of activity permitted. According to Austrade , such leases cover about 44% of mainland Australia (3,380,000 km (1,310,000 sq mi)), mostly in arid and semi-arid regions and the tropical savannahs . They usually allow people to use the land for grazing traditional livestock, but more recently have been also used for non-traditional livestock (such as kangaroos or camels ), tourism and other activities. Management of

4320-430: The smaller macropods to land clearing for pastoral agriculture and habitat changes brought to the Australian landscape by humans. Many of the smaller species are rare and endangered, while kangaroos are relatively plentiful, despite a common misconception to the contrary. The kangaroo along with the koala are symbols of Australia . A kangaroo appears on the Australian coat of arms and on some of its currency , and

4392-468: The station, along with Mabel Downs, Alice Downs and Texas Downs, together known as the Springvale Aggregation. Together they cover 604,430 ha (1,493,600 acres) and are stocked with 35,000 head of cattle. Traditional owners of the land were keen to work with the new owners, hoping for some of the land to be developed as tourist destinations, which would create jobs for Indigenous people in

4464-400: The tendons rather than by any muscular effort. This is true in all animal species which have muscles connected to their skeletons through elastic elements such as tendons, but the effect is more pronounced in kangaroos. There is also a link between the hopping action and breathing: as the feet leave the ground, air is expelled from the lungs; bringing the feet forward ready for landing refills

4536-401: The thick fur on its mother's abdomen into the pouch, which takes about three to five minutes. Once in the pouch, it fastens onto one of the four teats and starts to feed. Almost immediately, the mother's sexual cycle starts again. Another egg descends into the uterus and she becomes sexually receptive. Then, if she mates and a second egg is fertilised, its development is temporarily halted. This

4608-437: The vegetation they have eaten, chew it as cud , and then swallow it again for final digestion. However, this is a different, more strenuous, activity than it is in ruminants , and does not take place as frequently. Different species of kangaroos have different diets, although all are strict herbivores . The eastern grey kangaroo is predominantly a grazer , and eats a wide variety of grasses, whereas some other species such as

4680-420: The weaker members of the group. The size and stability of mobs vary between geographic regions, with eastern Australia having larger and more stable aggregations than in arid areas farther west. Larger aggregations display high amounts of interactions and complex social structures, comparable to that of ungulates . One common behavior is nose touching and sniffing, which mostly occurs when an individual joins

4752-404: The winners. These fights may serve to establish dominance hierarchies among males, as winners of fights have been seen to displace their opponent from resting sites later in the day. Dominant males may also pull grass to intimidate subordinate ones. Kangaroos have a few natural predators . The thylacine , considered by palaeontologists to have once been a major natural predator of the kangaroo,

4824-462: The young are born at a very early stage of development—after a gestation of 31–36 days. At this stage, only the forelimbs are somewhat developed, to allow the newborn to climb to the pouch and attach to a teat . In comparison, a human embryo at a similar stage of development would be at about 7 weeks gestation (even in a modern intensive care unit, premature babies born at less than 23 weeks gestation are usually not mature enough to survive). When

4896-528: The young ones are joeys . The collective noun for a group of kangaroos is a mob, court, or troupe. There are four extant species that are commonly referred to as kangaroos: In addition, there are about 50 smaller macropods closely related to the kangaroos in the family Macropodidae . Kangaroos and other macropods share a common ancestor with the Phalangeridae from the Middle Miocene . This ancestor

However, when Phillip Parker King visited the Endeavour River region in 1819 and 1820, he maintained that the local word was not kangaroo but menuah perhaps referring to a different species of macropod. There are similar, more credible stories of naming confusion, such as with the Yucatán Peninsula . Kangaroos are often colloquially referred to as "roos". Male kangaroos are called bucks, boomers, jacks, or old men; females are does, flyers, or jills; and

5040-468: Was beached for almost seven weeks to repair damage sustained on the Great Barrier Reef . Cook first referred to kangaroos in his diary entry of 4 August. Guugu Yimithirr is the language of the people of the area. A common myth about the kangaroo's English name is that it was a Guugu Yimithirr phrase for "I don't know" or "I don't understand". According to this legend, Cook and Banks were exploring

From the Late Miocene through the Pliocene and into the Pleistocene the climate got drier, which led to a decline of forests and expansion of grasslands. At this time, there was a radiation of macropodids characterised by enlarged body size and adaptation to

5184-403: Was stuffed (by taxidermists who had never seen the animal before) and displayed to the general public as a curiosity. The first glimpse of a kangaroo for many 18th-century Britons was a painting by George Stubbs . Kangaroos and wallabies belong to the same taxonomic family ( Macropodidae ) and often the same genera, but kangaroos are specifically categorised into the four largest species of
