The European hare ( Lepus europaeus), also known as the brown hare, is a species of hare native to Europe and parts of Asia. It is among the largest hare species and is adapted to temperate, open country. Hares are herbivorous and feed mainly on grasses and herbs, supplementing these with twigs, buds, bark and field crops, particularly in winter. Their natural Predation include large birds of prey, canidae and . They rely on high-speed endurance running to escape predation, having long, powerful limbs and large nostrils.
Generally nocturnal and shy in nature, hares change their behaviour in the spring, when they can be seen in broad daylight chasing one another around in fields. During this spring frenzy, they sometimes strike one another with their paws ("boxing"). This is not just competition between males, but also a female hitting a male, either to show she is not yet ready to mate or to test his determination. The female nests in a depression on the surface of the ground rather than in a burrow and the young are active as soon as they are born. Litters may consist of three or four young and a female can bear three litters a year, with hares living for up to twelve years. The breeding season lasts from January to August.
The European hare is listed as being of least concern by the International Union for Conservation of Nature because it has a wide range and is moderately abundant. However, populations have been declining in mainland Europe since the 1960s, at least partly due to changes in farming practices. The hare has been hunted across Europe for centuries, with more than five million being shot each year; in Britain, it has traditionally been hunted by beagling and hare coursing, but these field sports are now illegal. The hare has been a traditional symbol of fertility and reproduction in some cultures and its courtship behaviour in the spring inspired the English idiom mad as a March hare.
There is some debate as to whether the European hare and the Cape hare are the same species. A 2005 nuclear gene pool study suggested that they are, but a 2006 study of the mitochondrial DNA of these same animals concluded that they had diverged sufficiently widely to be considered separate species. A 2008 study claims that in the case of Lepus species, with their rapid evolution, species designation cannot be based solely on mtDNA but should also include an examination of the nuclear gene pool. It is possible that the genetic differences between the European and Cape hare are due to geographic separation rather than actual divergence. It has been speculated that in the Near East, hare populations are intergrading and experiencing gene flow. Another 2008 study suggests that more research is needed before a conclusion is reached as to whether a species complex exists; the European hare remains classified as a single species until further data contradicts this assumption.
Cladogenesis analysis suggests that European hares survived the last glacial period during the Pleistocene via refugia in southern Europe (Italian peninsula and Balkans) and Asia Minor. Subsequent colonisations of Central Europe appear to have been initiated by human-caused environmental changes. Genetic diversity in current populations is high with no signs of inbreeding. Gene flow appears to be biased towards males, but overall populations are matrilineally structured. There appears to be a particularly large degree of genetic diversity in hares in the North Rhine-Westphalia region of Germany. It is however possible that restricted gene flow could reduce genetic diversity within populations that become isolated.
Historically, up to 30 subspecies of European hare have been described, although their status has been disputed. These subspecies have been distinguished by differences in pelage colouration, body size, external body measurements, skull morphology and tooth shape.
Sixteen subspecies are listed in the IUCN red book, following Hoffmann and Smith (2005):
Twenty-nine subspecies of "very variable status" are listed by Chapman and Flux in their book on lagomorphs, including the subspecies above (with the exceptions of L. e. connori, L. e. creticus, L. e. cyprius, L. e. judeae, L. e. rhodius, and L. e. syriacus) and additionally:
This hare is one of the largest of the Lagomorpha. Its head and body length can range from with a tail length of . The body mass is typically between . The hare's elongated ears range from from the notch to tip. It also has long hind feet that have a length of between . The skull has nasal bones that are short, but broad and heavy. The supraorbital ridge has well-developed anterior and posterior lobes and the lacrimal bone projects prominently from the anterior wall of the orbit.
The fur colour is grizzled yellow-brown on the back; rufous on the shoulders, legs, neck and throat; white on the underside and black on the tail and ear tips. The fur on the back is typically longer and more curled than on the rest of the body. The European hare's fur does not turn completely white in the winter as is the case with some other members of the genus, although the sides of the head and base of the ears do develop white areas and the hip and rump region may gain some grey.
The European hare primarily lives in open fields with scattered brush for shelter. It is very adaptable and thrives in mixed farmland. According to a study in the Czech Republic, the mean hare densities were highest at elevations below , 40 to 60 days of annual snow cover, of annual precipitation, and a mean annual air temperature of around . With regards to climate, the European hare density was highest in "warm and dry districts with mild winters". In Poland, the European hare is most abundant in areas with few forest edges, perhaps because foxes can use these for cover. It requires cover, such as hedges, ditches and permanent cover areas, because these habitats supply the varied diet it requires, and are found at lower densities in large open fields. Intensive cultivation of the land results in greater mortality of young hares.
In Great Britain, the European hare is seen most frequently on arable farms, especially those with crop rotation and fallow land, wheat and sugar beet crops. In mainly grass farms, its numbers increased with are improved pastures, some arable crops and patches of woodland. It is seen less frequently where foxes are abundant or where there are many . It also seems to be fewer in number in areas with high European rabbit populations, although there appears to be little interaction between the two species and no aggression. Although European hares are shot as game when plentiful, this is a self-limiting activity and is less likely to occur in localities where the species is scarce.
European hares forage in groups. Group feeding is beneficial as individuals can spend more time feeding knowing that other hares are being vigilant. Nevertheless, the distribution of food affects these benefits. When food is well-spaced, all hares are able to access it. When food is clumped together, only dominant hares can access it. In small gatherings, dominants are more successful in defending food, but as more individuals join in, they must spend more time driving off others. The larger the group, the less time dominant individuals have in which to eat. Meanwhile, the subordinates can access the food while the dominants are distracted. As such, when in groups, all individuals fare worse when food is clumped as opposed to when it is widely spaced.
The mating system of the hare has been described as both polygynous (single males mating with multiple females) and promiscuous. Females have six-weekly reproductive cycles and are receptive for only a few hours at a time, making competition among local bucks intense. At the height of the breeding season, this phenomenon is known as "March madness", when the normally nocturnal bucks are forced to be active in the daytime. In addition to dominant animals subduing subordinates, the female fights off her numerous suitors if she is not ready to mate. Fights can be vicious and can leave numerous scars on the ears. In these encounters, hares stand upright and attack each other with their paws, a practice known as "boxing", and this activity is often between a female and a male and not purely between competing males as was previously believed. When a doe is ready to mate, she runs across the countryside, starting a chase that tests the stamina of the following males. When only the fittest male remains, the female stops and allows him to copulate. Female fertility continues through May, June and July, but testosterone production decreases in males and sexual behaviour becomes less overt. Litter sizes decrease as the breeding season draws to a close with no pregnancies occurring after August. The testes of males begin to regress and sperm production ends in September.
Does give birth in hollow depressions in the ground. An individual female may have three litters in a year with a 41- to 42-day gestation period. The young have an average weight of around at birth. The leverets are fully furred and are precocial, being ready to leave the nest soon after they are born, an adaptation to the lack of physical protection relative to that afforded by a burrow. Leverets disperse during the day and come together in the evening close to where they were born. Their mother visits them for nursing soon after sunset; the young suckle for around five minutes, urinating while they do so, with the doe licking up the fluid. She then leaps away so as not to leave an olfactory trail, and the leverets disperse once more. Young can eat solid food after two weeks and are weaned when they are four weeks old. While young of either sex commonly explore their surroundings, natal dispersal tends to be greater in males. Sexual maturity occurs at seven or eight months for females and six months for males.
European hares have both external and internal parasites. One study found that 54% of animals in Slovakia were parasitised by and over 90% by coccidia. In Australia, European hares were reported as being infected by four species of nematode, six of coccidian, several and two canine Cestoda. They were also found to host rabbit fleas ( Spilopsyllus cuniculi), stickfast fleas ( Echidnophaga myrmecobii), lice ( Haemodipsus setoni and H. lyriocephalus), and mites ( Leporacarus gibbus).
European brown hare syndrome (EBHS) is a disease caused by a Caliciviridae similar to that causing rabbit haemorrhagic disease (RHD) and can similarly be fatal, but cross infection between the two mammal species does not occur. Other threats to the hare are pasteurellosis, yersiniosis (pseudo-tuberculosis), coccidiosis and tularaemia, which are the principal sources of mortality.
In October 2018, it was reported that a mutated form of the rabbit haemorrhagic disease virus (RHDV2) may have jumped to hares in the UK. Normally rare in hares, a significant die-off from the virus has also occurred in Spain.
In Northern Europe, Easter imagery often involves Easter Bunny. Citing folk Easter customs in Leicestershire, England, where "the profits of the land called Harecrop Leys were applied to providing a meal which was thrown on the ground at the 'Hare-pie Bank'", the 19th-century scholar Charles Isaac Elton proposed a possible connection between these customs and the worship of Ēostre. In his 19th-century study of the hare in folk custom and mythology, Charles J. Billson cites folk customs involving the hare around Easter in Northern Europe, and argues that the hare was probably a sacred animal in prehistoric Britain's festival of springtime.Billson, Charles J. (1892). "The Easter Hare" as published in Folk-Lore, Vol. 3, No. 4 (December 1892). Taylor & Francis, on behalf of Folklore Enterprises. p. 448. Observation of the hare's springtime mating behaviour led to the popular English idiom "mad as a March hare", with similar phrases from the sixteenth century writings of John Skelton and Thomas More onwards. The mad hare reappears in Alice's Adventures in Wonderland by Lewis Carroll, in which Alice participates in a crazy tea-party with the March Hare and the The Hatter.
Any connection of the hare to Ēostre is doubtful. John Andrew Boyle cites an etymology dictionary by Alfred Ernout and Antoine Meillet, who wrote that the lights of Ēostre were carried by hares, that Ēostre represented spring fecundity, love and sexual pleasure. Boyle responds that almost nothing is known about Ēostre, and that the authors had seemingly accepted the identification of Ēostre with the Norse goddess Freyja, but that the hare is not associated with Freyja either. Boyle adds that "when the authors speak of the hare as the 'companion of Aphrodite and of satyrs and cupids' and 'in the Middle Ages the appears beside the figure of mythological Luxuria', they are on much surer ground."
The hare is a character in some fables, such as The Tortoise and the Hare of Aesop. The story was annexed to a philosophical problem by Zeno of Elea, who created a set of paradoxes to support Parmenides' attack on the idea of continuous motion, as each time the hare (or the hero Achilles) moves to where the tortoise was, the tortoise moves just a little further away. The German Renaissance artist Albrecht Dürer realistically depicted a hare in his 1502 watercolour painting Young Hare.
Hare is traditionally cooked by jugging: a whole hare is cut into pieces, marinated and cooked slowly with red wine and juniper berries in a tall jug that stands in a pan of water. It is traditionally served with (or briefly cooked with) the hare's blood and port wine.
The International Union for Conservation of Nature has evaluated the European hare's conservation status as being of least concern. However, at low population densities, hares are vulnerable to as the available gene pool declines, making inbreeding more likely. This is the case in northern Spain and in Greece, where the restocking by hares brought from outside the region has been identified as a threat to regional gene pools. To counteract this, a captive breeding program has been implemented in Spain, and the relocation of some individuals from one location to another has increased genetic variety. The Bern Convention lists the hare under Appendix III as a protected species. Several countries, including Norway, Germany, Austria and Switzerland, have placed the species on their Red Lists as "near threatened" or "threatened".
