Gibraltar Barbary Macaque

Originally from the Atlas Mountains and the Rif Mountains of Morocco, the Barbary macaque population in Gibraltar is the only wild monkey population on the European continent. Although most Barbary monkey populations in Africa are experiencing decline due to hunting and deforestation, the Gibraltar population is increasing. , some 300 animals in five troops occupy the Upper Rock area of the Gibraltar Nature Reserve, though they make occasional forays into the town. As they are a tailless species, they are also known locally as Barbary apes or rock apes, despite being classified as monkeys (''Macaca sylvanus''). Spanish speakers simply refer to them as ''monos'' () when conversing in Spanish, although English is the native language as the area is a British overseas territory.

Origin

The name Barbary refers to the Berber People of North Africa who, since the beginning of history, had ties with the animals surrounding their region, such as the Barbary macaques. The macaque population had also been present on the Rock of Gibraltar long before Gibraltar was captured by the British in 1704 and according to records, since prior to reconquest of Gibraltar from the Muslims. It was during the Islamic period where a purported introduction may have taken place. In his work ''Historia de la Muy Noble y Más Leal Ciudad de Gibraltar'' (''History of the Very Noble and Most Loyal City of Gibraltar''), written between 1605 and 1610, Alonso Hernández del Portillo, the first chronicler of Gibraltar, wrote:

In his ''History of Gibraltar'' (1782), Ignacio López de Ayala, a Spanish historian like Portillo, wrote of the monkeys:

Repeated introduction of animals and the lack of reliable data concerning founders of the Gibraltar macaque population has obscured their origin. The fact that all extant Gibraltarian mtDNA haplotypes were also found in North Africa, combined with the lack of fossil evidence of ''M. sylvanus'' in Gibraltar at the end of the last glaciation, greatly diminishes the possibility that the Gibraltar macaques represent or include any remnant of the original European population, a possibility which can nevertheless not be excluded.Phylogeography of Barbary macaques (''Macaca sylvanus'') and the origin of the Gibraltar colony
Clear distinction between Algerian and Moroccan haplotypes permits attribution of the Gibraltar colony to founders from both regions. Indeed, it had been earlier suggested that the original Gibraltar macaques were a remnant of populations that had spread throughout Southern Europe during the Pliocene'' species is listed as endangered by the IUCN Red List and is declining. About 75% of the total population is found in the Middle Atlas Mountains.

During the Pleistocene, this species inhabited a greater area around the Mediterranean coasts and Europe. During warm interglacials it reached as far north as Germany and Britain, while retreating to southern glacial refugia during cold periods. During the Last Glacial Period, the species decreased to extinction in the Iberian Peninsula 30,000 years ago. The species' disappearance from Europe in the latest Pleistocene, as opposed to its survival during earlier glacial periods, is not fully understood, but is assumed to be due to climatic deterioration and associated vegetation change, perhaps in combination with human pressure. Generally, it coincided with the extinction of other primarily large mammals, such as the hippopotamus (''Hippopotamus amphibius'') and narrow-nosed rhinoceros (''Stephanorhinus hemitoechus'')

Tourism

The Gibraltar Barbary macaques are considered by many to be the top tourist attraction in Gibraltar. The most popular troop is that of Queen's Gate at the Ape's Den, where people can get especially close to the monkeys. They will often approach and sometimes climb onto people, as they are used to human interaction. Nevertheless, they are still wild animals and will bite if frightened or annoyed.

Deliberately feeding the macaques in Gibraltar is now an offence punishable by law. Anyone caught feeding the monkeys is liable to be fined up to £4,000.

Military care

Gibraltar's Barbary macaque population was under the care of the British Army and later the Gibraltar Regiment from 1915 to 1991, who carefully controlled a population that initially consisted of a single troop. The 'Keeper of the Apes' would keep the official records, maintaining an up-to-date register for each ape, listing their births and names and supervising their diet, which they drew officially every week. The food allowance of fruit, vegetables and nuts was included in the budget, set by the War Office at £4 a month in 1944. They would humorously announce births in the 'Gibraltar Chronicle': "Rock Apes. Births: To Phyllis, wife of Tony, at the Upper Rock, on 30th June 1942— a child. Both doing well." much to the delight of readers. They were named after governors, brigadiers and high-ranking officers. Any ill or injured monkey needing surgery or any other form of medical attention was taken to Royal Naval Hospital Gibraltar and received the same treatment as would an enlisted service man. When UK-based infantry units were withdrawn and garrison duty was left to the Gibraltar Regiment, the Government of Gibraltar took over responsibility for the monkeys.

Officers in charge

* Lt Bill Parker of the Royal Artillery (1944 – unknown)
* Major W O Skelton of the Royal Artillery (''circa'' 1951)
* Gunner Wilfred Portlock of the Royal Artillery Regiment (''circa'' 1940 – 1960)
* Sgt Alfred Holmes of the Gibraltar Regiment (''circa'' 1958 – ''circa'' 1986)
* Cpl. Ernest Asquez of the Gibraltar Regiment (''circa'' 1986 – 1991)

Royal visit

On 11 May 1954, Queen Elizabeth II and the Duke of Edinburgh visited the ape packs while on a visit to Gibraltar. A photograph captured the Queen feeding a Barbary ape while the Duke of Edinburgh stood next to battle-dressed ape-keeper Gunner Wilfred Portlock.

Management

The monkeys are currently managed by the Gibraltar Ornithological and Natural History Society (GONHS), and veterinarian expertise is provided by the Gibraltar Veterinary Clinic. The macaques receive a daily supply of fresh water and vegetables, fruit and seeds as supplement to natural food resources (leaves, olives, roots, seeds and flowers). The animals are caught on a regular basis to check their health status. Additionally, body size, weight and several other measurements are taken. Finally, the animals are given a tattoo number and a microchip as a means of identification. But tattoos are not the only way to recognise individual macaques; many of them have particular marks, scars or spots which can be used as distinguishing features. All monkeys are photographed and the pictures and individual characteristics are catalogued. Cataloguing work is carried out by the GONHS. The GONHS also does collaborative studies with the Scientific Institute of Rabat-Agdal University (Morocco), the University of Notre Dame (Indiana, United States), the University of Vienna (Austria), the German Primate Centre (Germany) and the University of Zurich (Switzerland).

Once every year, a census is conducted to provide data and to monitor reproductive success of the whole population.
These demographic data are important for the management of the population generally, and fertility regulation in selected individuals, specifically. Since Barbary macaque females reproduce well, the population on Gibraltar is steadily increasing, which in turn puts pressure on the limited habitat. Animal population control is therefore an essential part of the effective management of the population. In 2008 a small group of macaques that had permanently relocated to the Catalan Bay area were culled. In 2012 the Government Minister for Health and the Environment John Cortes stated that the Government was investigating the possibility of reintroducing over a hundred macaques to their natural habitat in North Africa.

In October 2014, the Government of Gibraltar announced that it would export 30 of the monkeys to a safari park in Scotland. This caused a journalist spin that they were sent to Scotland for being especially "disruptive". By 2017, the monkeys at the Blair Drummond Safari Park near Stirling were doing well and the first births were being registered.

Legend

A popular belief holds that as long as Gibraltar Barbary macaques exist on Gibraltar, the territory will remain under British rule. In 1942 (during World War II), after the population dwindled to just seven monkeys, UK Prime Minister Winston Churchill ordered their numbers be replenished immediately from forest fragments in both Morocco and Algeria because of this traditional belief.

In another story, the Gibraltar Barbary macaques entered the Rock via a subterranean passage between Lower St. Michael's Cave and Morocco.

In popular culture

* The Gibraltar Barbary macaque is portrayed on the Gibraltar pound's five-pence coin since 1988 and on the tercentenary edition one penny coin since 2004.
* They are featured in the 2007 novel ''The Girl Who Kicked the Hornets' Nest'' by Stieg Larsson.
* The Gibraltar Barbary macaques are also central to the plot of Paul Gallico's 1962 comedic novel ''Scruffy'' and the 1962 British comedy film ''Operation Snatch'', both set during WWII when their numbers were dwindling.
* James Bond (Timothy Dalton) is startled by one in the pre-credit sequence of the 1987 film ''The Living Daylights'' during a training exercise on Gibraltar. Several more are seen watching and getting out of the way of Bond's struggle with an assassin on a burning munitions truck as it speeds through the tourist zone.
* They are part of a flashback sequence in ''The Atlantis Gene'' by A.G. Riddle.
