Gibraltar

Barbary Partridge Alectoris barbara ©Aaron Baglietto Website

Gibraltar is a British Overseas Territory and city located at the southern tip of the Iberian Peninsula, on the Bay of Gibraltar, near the exit of the Mediterranean Sea into the Atlantic Ocean (Strait of Gibraltar). It has an area of just 6.7 km2 (2.6 square miles) and is bordered to the north by Spain (Campo de Gibraltar). The shoreline measures 12 km (7.5 miles) in length. Morocco lies just over 14km (8.9 miles) to the south across the Strait. The landscape is dominated by the Rock of Gibraltar, at the foot of which is a densely populated town area, home to about 33,000 people, primarily Gibraltarians. There are two coasts of Gibraltar: the East Side, which contains the settlements of Sandy Bay and Catalan Bay; and the Westside, where the vast majority of the population lives.

Having negligible natural resources and few natural freshwater resources, limited to natural wells in the north, until recently Gibraltar used large concrete or natural rock water catchments to collect rainwater. Fresh water from the boreholes is nowadays supplemented by two desalination plants: a reverse osmosis plant, constructed in a tunnel within the rock, and a multi-stage flash distillation plant at North Mole. Gibraltar’s terrain consists of the 426 m-high (1,398 ft) Rock of Gibraltar made of Jurassic limestone, and the narrow coastal lowland surrounding it. It contains many tunnelled roads, most of which are still operated by the military and closed to the general public.

Gibraltar has a Mediterranean climate with mild, rainy winters and summers that are very warm to hot and humid, but with very little rainfall. As is the case for nearby Algeciras and Tarifa, summers are significantly cooler and annual temperature more constant than other cities on the southern coast of the Iberian peninsula because of its position on the Strait of Gibraltar. Its average annual temperature is 21.7 °C as a daily high and 15.8 °C as the overnight low. In the coldest month, January, the high temperature averages 16.3 ° and the overnight low averages 11.2 °C and the average sea temperature is 16 °C. In the warmest month, August, the daily high temperature averages 28.4 °C and the overnight low averages 21.2 °C with the average sea temperature is 22 °C.

Most of the Rock’s upper area is covered by a nature reserve which is home to around 230 Barbary Macaques Macaca sylvanus, the famous apes of Gibraltar, which are actually monkeys. These are the only wild apes or monkeys found in Europe and are listed as endangered by the IUCN Red List and is declining. Three-quarters of the world population live in the Middle Atlas Mountains of Morocco. Other mammals found in Gibraltar include rabbits, foxes and bats.

Migrating birds are very common and Gibraltar is home to the only Barbary partridges found on the European continent.

Birding Gibraltar

The famous Rock of Gibraltar’s summit ridge, rising to 426m, offers superb if vertiginous views over the westernmost Mediterranean, the Costa del Sol and, especially, the Strait of Gibraltar itself. The Moroccan shore is very close and views often extend to the Rif Mountains beyond.

The strategic position of Gibraltar is the root of its ornithological fame. Migration of soaring birds, i.e. storks and raptors, occurs year-round in some form and numbers can be spectacular in the peak seasons of March-May and August-October, almost invariably during periods of westerly winds. The most abundant are Black Kites and Eurasian Honey-buzzards, which both produce daily counts of thousands at peak times. Significant but lesser concentrations occur of Egyptian and Griffon Vultures, Short-toed and Booted Eagles, Marsh and Montagu’s Harriers, Sparrowhawks and Ospreys, as well as White and Black Storks. Scarcer migrant raptors include Rüppell’s Vulture, Pallid Harrier, Long-legged Buzzard, Lesser Spotted Eagle, Eleonora’s Falcon and Lanner, all of which occur more or less annually.

Migration of seabirds is also an all-year phenomenon and features important numbers of Cory’s, Scopoli’s and Balearic Shearwaters, Northern Gannets, Great Skuas; Mediterranean, Black-headed, and Audouin’s Gulls, and Sandwich Terns. Many other seabirds occur regularly, including Lesser Crested Terns (September/mid-November).

The Gibraltar list grows slowly but steadily. It may be consulted on the GONHS website. It includes a particularly comprehensive contingent of passerines, many of them migrants grounded on the Rock by inclement weather, often during the frequent bouts of strong easterly winds which produce the famous levanter cloud over the summit. A diversity of vagrant species enlivens the birding scene; examples have included Common Eider, Allen’s Gallinule, Moroccan White Wagtail, Seebohm’s Wheatear, Yellow-browed and Pallas’s Warblers, Mountain Chiffchaff, Red-breasted Flycatcher and Hooded Crow.

Resident and breeding species are few but Gibraltar has one of only two colonies of Shags in the westernmost Mediterranean and is the only mainland site in Europe for Barbary Partridges. Other local breeders include Peregrines; Common, Pallid and Alpine Swifts, Blue Rock Thrushes and, since their re-colonisation in 2004, a pair of Eagle Owls. The thousands of Yellow-legged Gulls are an unmissable feature; they even nest on rooftops and in the pine trees of the Botanic Garden.

    WebsiteSatellite View
    The Gibraltar Nature Reserve (formerly the Upper Rock Nature Reserve) is a protected nature reserve in the British Overseas Territory of Gibraltar that covers over 40% of the country's land area. The Rock has been identified as an Important Bird Area by BirdLife International because it is a migratory bottleneck, or choke point, for an estimated 250,000 raptors that cross the Strait annually, and because it supports breeding populations of Barbary partridges and lesser kestrels.

    We had a date this morning: to meet El Grupo Ornitológico del Estrecho (GOES – The Ornithological Group of the Strait). The rendez-vous was some wild olive scrub on the edge of Algeciras which, we heard, had been in and is now out of the Natural Park. A bird ringing session was underway, and one GOES group member was taking feather mites from captured passerines as part of a detailed study…

    PDF Report
    The narrowest point of the Strait of Gibraltar is a mere 14 km across to the African continent. The clear views of the Jbel Musa, on the other side of The Strait, were one of the first things we would see in the morning during this tour. The combination of constant changing winds and powerful thermals makes this area a unique strategic crossing point for raptors, allowing stunning views of these and other avian migrants.

    Raptor watch Strait of Gibraltar September 2017 - We had a 5 days holiday from september 21st to sept 26th. Weather was unusually hot, with temperatures close to 30 C, a bit inland. We stayed some nights in La Alcaidesa, some 40 mins drive from Tarifa. The last nights we, as usual, stayed at Dos Mares Hotel, just outside Tarifa.

    Report
    As we are getting close to Tarifa, we see the Rock of Gibraltar on our side and the Djebel Musa on the African side. Our first stop is in route, in Palmones river mouth where a Lesser Crested Tern was spotted few days before.

  • 2021 [09 September] - Simon Tonkin

    PDF Report
    Our action-packed days together here in The Straits showed us magical avian migration, with swirling masses of Eagles and Storks making the 14km crossing to Africa, and the richness of the two meeting seas with Longfinned Pilot Whales, Common and Striped Dolphins, Yellow-finned Tuna and Mediterranean Flying Fish. The juxtaposition of human culture and history was demonstrated in the landscape and food but also the combined natural history of the wondrous Straits of Gibraltar.

  • Gibraltar - Tourist Board - Birdwatching

    Webpage
    As the Strait of Gibraltar is the narrowest crossing point for birds migrating to and from Europe and Africa, the Rock offers unrivalled bird watching opportunities. 315 species of birds have been recorded, many of which are migratory. Gibraltar, at the head of the Strait, is a prominent headland, which accumulates migrants during the passage periods. The vegetation on the Rock, unique in southern Iberia, provides a temporary home for many species of migratory birds that stop to rest and feed before continuing migration for their crossing over the desert and sea. In spring they return to replenish before continuing their journeys to Western Europe, journeys that may take them as far as Greenland or Russia.
