Gibraltar's Barbary Partridge: Europe Has Thousands, the Rock Has Maybe 200

15 September 2026 Last checked 2026-09-15

Gibraltar's national bird is not Europe's only wild Barbary partridge. Sardinia has thousands of pairs. What Gibraltar has is rarer, stranger and harder won than the usual line admits.

Sardinia holds an estimated 5,000 to 10,000 breeding pairs of Barbary partridge, more than half of a European total put at 7,500 to 20,000 pairs. Gibraltar's last published count was 150 to 200 birds. Both places are in Europe, which makes the line repeated across most pages about Gibraltar's national bird, that this is Europe's only wild Barbary partridge, wrong.

The accurate version is narrower and more interesting. Gibraltar holds the only self sustaining Barbary partridge population anywhere on the European mainland. Every other European bird of the species sits on an island, and the great majority sit on one island. The species was introduced to continental Portugal at some point, but we could find no evidence that anything survives there, which is why the careful sources put the qualifier on the claim rather than dropping it.

The other word worth arguing over is wild. Partridges bred from Moroccan stock have been released onto the Rock in repeated batches since about 2014, by the Gibraltar Ornithological and Natural History Society and the Government's environment department. Whether what walks the Upper Rock today is a wild population, a maintained one, or something between the two is a fair question, and nobody has published an answer.

A bird you can name in three seconds

Alectoris barbara was described by Bonnaterre in 1790 and runs 33 to 36 cm long, with a grey brown back, grey breast, buff belly, rufous streaked white flanks and red legs. The mark that settles it is the collar: a broad reddish brown gorget below a light grey face. Spain's red legged partridge, Alectoris rufa, is common across Spain and is not found in Gibraltar at all, so a partridge on the Rock is a Barbary partridge.

It nests in a thinly lined scrape on the ground and lays 10 to 16 eggs. A clutch that size tells you most of what you need to know about how many chicks are expected to survive. It eats seeds and some insects, and it is the reverse design on Gibraltar's one penny coin.

Was it ever wild here, and does that matter

Nobody knows how the species reached Gibraltar. The UK Overseas Territories Conservation Forum factsheet sets out three possibilities and declines to pick one: birds imported during the Moorish occupation, birds brought over by the British in the mid 1700s in a consignment of game from Barbary, or an indigenous population that was always here. It adds that the answer may be a combination of all three.

The mid 1700s route carries two dates in the secondary accounts: a 1749 order by Governor Humphrey Bland authorising the import of game from Barbary for shooting, and the first Gibraltar records of the bird by the Reverend John White in 1771. We could not open the original Order Book, so treat those two dates as the received account rather than something we checked at source.

Late Pleistocene Alectoris fossils have been found on the Rock, and they do not settle it either. The same factsheet notes those birds may have been ancestors of the red legged partridge rather than of this one.

The honest position is that the origin is unresolved, and that Gibraltar is not unusual in this. Sardinia's population may also be an old introduction. So may the Canary Islands birds. Outside North Africa, what counts as a native Barbary partridge is an open question almost everywhere.

The grazing stopped and the scrub closed in

This is the part almost nobody tells, and it is the part that explains the rest.

The Upper Rock has not always been as green as it looks now. The 2005 Upper Rock Nature Reserve management and action plan, written by Charles Perez and Keith Bensusan and published by GONHS, traces a landscape that went from presumably forested, to completely denuded during the Great Siege, and back again to dense maquis with scattered patches of garrigue and pseudosteppe. In the earlier phases goats and some cattle grazed the slopes and trees came down for fuel. The grazing kept the ground open.

A Barbary partridge needs open ground. The plan is blunt about it: the species requires open areas in order to survive, and that habitat was becoming less common on the Upper Rock. It lists the bird as a Schedule 3 species under the Nature Protection Ordinance 1991 and, citing Tucker and Heath, as endangered within Europe.

The firebreaks were supposed to supply that open ground. Instead the plan records that most firebreaks on the Upper Rock were mismanaged and growing steadily denser, to the point of becoming unsuitable even as feeding areas for bats. Rabbits, which want open ground for the same reasons, had thinned out alongside the partridge.

So the mechanism is not exotic. Take away the grazers, stop cutting the firebreaks, let the maquis thicken, and a bird that needs bare rock and low scrub runs out of places to stand. Add feral cats, which the plan singles out as a grave concern because they were being fed routinely near St Michael's Cave and the Upper Galleries, and the decline stops looking mysterious.

One detail in that plan we have not seen anywhere else. Free roaming chickens, pheasants and peacocks on the Upper Rock were described as occupying a similar niche to the partridge and competing with it directly, as well as carrying diseases transmissible to it. Gibraltar's national bird was losing ground to escaped poultry.

What the recovery actually involved

By the time the work began the population was down to perhaps 30 pairs on one account and fewer than 25 birds on another. The response had three parts, in this order: clear the habitat, deal with the introduced predators, then restock. Eggs and chicks from Morocco were hatched and reared, some birds were kept back to breed in captivity, and every released bird was wing tagged or leg ringed so it could be told apart from a local one.

Read the middle of that table closely. The Chronicle reported in September 2016 that another 50 birds had been released into selected areas of the reserve, with Dr John Cortes, then Minister for the Environment, calling it a success story. The word another matters. Releases had already been running for at least a year by that point, so the 150 to 200 birds reported four years later is not simply what 25 birds grew into.

Vincent Robba, who runs the breeding programme for GONHS, gave the 2020 figure of 150 to 200 and put the split at roughly 80 per cent from the wild and 20 per cent from the breeding programme. He put mortality at about 75 per cent. Gulls, cats, foxes, snakes, ravens and juvenile Barbary macaques all take birds. The release method was small pens set around the Rock in groups of five or six, concentrated on the eastern side between Tallis Slopes and Both Worlds.

It is the same shape as the Gibraltar campion, declared extinct in 1992 and found again as three plants on an Upper Rock ledge in 1994: a small territory, a tiny population, and a recovery that depends entirely on a handful of people continuing to do the work.

Where to look, and why it is the east side

Here is a convergence worth knowing. The same 2020 study in the European Journal of Wildlife Research that carries the Sardinian population estimate surveyed the birds across northeastern Sardinia, using 376 listening points at 34 sites over the 2012 and 2013 breeding seasons. It found the species in shrubland, garrigue and meadow, on slopes facing east, and especially between sea level and 200 metres. It found them avoiding forest and north western slopes.

Gibraltar put its release pens on the eastern slopes. Whether that came from the same evidence or was arrived at independently, the two point the same way, and it hands a visitor a rule that beats wandering. Look east. Look low. Look at open ground rather than into trees.

In practice that means cleared firebreaks, road edges and open scrub, not the wooded stretches. The reserve's own bird page says the partridge can often be found foraging amongst the shrubbery, which is true and not very useful. Sharper version: scan the ground, not the canopy, and use your ears. The Sardinian team surveyed this bird by listening rather than looking, which tells you which sense to trust. If you are on the Rock in autumn you will probably be looking up anyway, at the raptor migration crossing the Strait, so make the partridge the reason you also look down.

Practical notes for 2026

The cable car is shut. It has been under full refurbishment and the Gibraltar Nature Reserve says it is expected to reopen in 2027. For partridge watching that matters less than it sounds, because the cable car takes you to the top and these birds are lower down and further east.

A one day Nature Reserve ticket is 30 GBP for adults aged 11 and over, 22 GBP for children aged 5 to 11, and free for under fives. It covers every site and trail in the reserve and stays valid for 90 days. The reserve opens 9:30am to 7pm from May to September and 9am to 6pm from October to April, closes on 25 December and 1 January, and shuts at 3:30pm on 24 and 31 December.

Drive slowly. Inside one week of June 2018, two partridge chicks were killed by vehicles on Engineer Road, and GONHS asked the environment department to bring speeds down across the Upper Rock road network. Parent birds walk their chicks across those roads. The macaques are on the same roads, and the same argument applies.

What we could not verify

No population count for the Barbary partridge in Gibraltar has been published since October 2020, as far as we can find. The Government said in October 2023 that the population had been re-established, alongside the European rabbit, but attached no number to it. Anyone telling you how many partridges are on the Rock in 2026 is guessing, and so would we be. If you want a current figure, GONHS at Jews Gate is the place to ask.

There is a second gap, and it is the more useful one. Every bird released on the Rock was wing tagged or leg ringed specifically so it could be told apart from a local bird. That means somebody, somewhere, holds the one number that would answer the wild question outright: what share of the partridges now on the Rock carry a tag. We could not find that figure published anywhere. Until it is, Vincent Robba's 80 per cent from the wild remains a field estimate by the person closest to the birds rather than a resight rate, and it should be read as exactly that.

Nor could we find a published total for how many birds have been released since the programme began. The 50 released in September 2016 were described as another 50, which implies an earlier batch, and the 2020 report describes ongoing releases in pens of five or six. The cumulative figure is not in the public record.

So is it wild

Our answer, for what it is worth: yes, with a qualification that should be said out loud rather than buried. The birds breed unaided, they have spread into habitat beyond the release areas, and released birds have paired with local ones. That is a wild population on any working definition. It is also a population that needed imported birds, active predator control and cleared habitat to get there, and that has not been publicly counted in nearly six years.

Calling it Europe's only wild Barbary partridge oversells the rarity and undersells the work. The accurate claim is better anyway. In a territory holding 37,936 people at the 2022 census, a North African gamebird that had fallen to a few dozen is breeding again on the eastern slopes, because people cut the scrub back and kept cutting it. The bird on the penny is there because of maintenance, not luck.

Seeing one from here

Victory Suites runs 100+ apartments in Gibraltar, and for anyone chasing this bird the operator's advantage is simply time of day. The eastern slopes take first light, the reserve opens at 9am in winter and 9:30am in summer, and if you want open ground before the reserve roads fill you need to be at the gate when it opens. Staying in the territory rather than driving in from Spain each morning is the difference between arriving at opening and arriving at eleven. We list across 300+ booking channels, so book wherever suits you, but book on the Gibraltar side of the frontier if the bird is the point of the trip.

One last honest note. You may not see one. A couple of hundred ground dwelling birds spread across a nature reserve is not a guaranteed sighting, and anyone promising otherwise has not looked for one. Go for the walk, keep east and low, and treat the partridge as the bonus rather than the plan.
