Everything about the mysterious Alpine ibex

The Alpine ibex is a mysterious creature on our wondrous planet.

And as it turns out, the story of the protection of this ungulate species is an illuminating example of recovery and renewal.

Today we look at the basics of Capra ibex, their return from near-extinction, and where you might try to catch a glimpse of them yourself. This story is a warning about our own behaviour. But it is also an example of the hope embodied in this species — one we were able to save through swift, courageous action, through raising community awareness, and through sure-footed leadership.

The basics of Capra ibex

Capra ibex is the scientific name for this beloved «mountain goat» known by a whole range of other names. Some examples are steinbock, bouquetin, simply ibex, and even Capra ibex ibex. If that last name seems redundant to you, you are absolutely right. This is a feature of botanical species with various subspecies. The double name helps us recognise differences while simultaneously acknowledging evolutionary kinship. Wild goat species once considered subspecies of the Alpine ibex include the Nubian ibex, the walia, and the Siberian ibex.

It is a mysterious, wild goat that lives in the European Alps. The endemic range of this species encompasses Italy, Switzerland, Austria, France, and even Slovenia. Evolutionary biologists and archaeologists have found fossils of a predecessor animal in Kenya, China, and Slovenia.

The Alpine ibex has a short, broad head. Its coat is brownish-grey with a light-coloured underbelly. These mammals molt twice a year – by September, a thicker coat grows in to prepare for the late autumn and winter months.

These goats are herbivores and climbers, moving through the Swiss Alps along the snowline, where the landscape is rugged, jagged, and rocky. They are classified as Artiodactyla. This means «animals with hooved feet«. It is a distinct category that also includes sheep, antelopes, camels, pigs, cattle, and giraffes. These animals are adapted to life in open grasslands, where they are most commonly found. The Alpine ibex is of course an exception – it inhabits the monstrous and majestic heights of the Alps.

The most striking feature, at least in male ibex, is their very long and pointed horns. They are not something you would want to get tangled up with.

These curved horns are not only extremely sharp, but also a magnificent example of sexual dimorphism in nature. The term sexual dimorphism is defined in zoology as «a marked difference in the size or appearance between the sexes of an animal, in addition to the difference between the reproductive organs themselves».

Male ibex not only have horns, but also a larger body size than their female counterparts.

Reproductive behaviour and life cycle habits

For most of the year, male and female ibex live separately from one another. This naturally changes during the breeding season, when the animals are in rut – typically in December of each year. The breeding season lasts six weeks.

Adult males compete for females by using their horns against one another. Sometimes male aggression can also take an indirect form, expressed through threats and displays of dominance. Scientists observe a «linear dominance hierarchy» among males, which is generally determined by horn size and group cohesion.

The courtship process is governed by this power dynamic and involves complex phases and behaviors — an indication that these animals are social beings with habits, preferences, and memories of previous encounters. After a male and female have mated, the gestation period lasts approximately 167 days. About 20% of ibex births result in twins. As with other goat species, these offspring are called «kids» until they mature into adults.

When not reproducing, the sexes separate again into distinct groups: adult male groups, female herds with their offspring, and groups of young individuals.

Individuals reach sexual maturity at 18 months, but continue to grow over the years. Females typically reach their full size between the ages of five and six. Males, on the other hand, take somewhat longer and reach their full size between nine and eleven years of age.

In the wild, these animals can live up to 19 years.

On the Brink of Extinction

Ibex have been documented in the fossil record since the Pleistocene. During this period, the Alpine ibex and the Spanish ibex diverged and evolved from the extinct Pleistocene species Capra camburgensis.

As is so often the case with human population growth and technological progress, as early as the 16th century we began to seriously encroach upon the endemic habitat of these alpine goats. Due to hunting and human encroachment, the population steadily declined.

Extirpation is a term meaning «to uproot and completely destroy». We use this word to describe an animal that has completely disappeared from a specific area, but not from the entire globe. Evidently, extirpation leads to extinction.

And that is precisely what happened in the case of the Alpine ibex: by the 18th century, these sharp-horned goats had disappeared from Germany and Switzerland. By the 19th century, they had also vanished from Austria and northeastern Italy.

The situation became critical: at a certain point, the only remaining area where Alpine ibex reached the snow line was the Gran Paradiso massif and the Vanoise massif. Fewer than 100 individuals remained there. This area (located in the western Italian Alps and the Maurienne Valley) was subsequently declared a park in order to save the species. At the time, it was designated by Victor Emmanuel II, the first king of unified Italy, as the «Royal Hunting Reserve of Gran Paradiso». In 1922, it was officially declared a national park. Thanks to these measures, the number of animals rose from near extinction to over 3’000.

A success story with obstacles

In some cases, this recovering population spread naturally into adjacent areas. However, reintroduction has been an important part of this success story. Today, there are over 30’000 Alpine ibex. And although they remain somewhat mysterious to us, their conservation status has improved significantly. They roam the Italian Alps, rutting, fighting, foraging. The IUCN lists them as one of the least endangered species. In a world increasingly defined by the climate crisis, this kind of success story is a rare blessing.

But conservation and reintroduction efforts cannot be completed overnight. Even though the size of the herds and the restored interactions within ecosystems are cause for celebration, these recovered populations have very low genetic diversity. Having recovered from so few individuals, the species is now inbred and particularly vulnerable to disease. This could pose a problem in the future.

Efforts to conserve species related to the ibex are also less encouraging. Two species of Iberian ibex, native to the Iberian Peninsula, have already gone extinct. And despite extensive cloning attempts, not a single specimen of these species has survived for more than a few minutes.

Where to see them today

The European Alps are an incredible place to visit for a variety of reasons. And thanks to conservation efforts, you may have the chance to see the mysterious Alpine ibex for yourself – even if it means venturing quite high up into the mountains. Pack your hiking boots!

The Gran Paradiso National Park remains a popular destination for basking in the wonders of ecology while scanning the snowline for wild goats. Among the ibex's relatives in this part of the world is the chamois – another mammal to keep an eye out for.

The story of the Alpine ibex continues. We observe them in their natural habitat and feel a responsibility to protect them and the delicate systems in which they climb, graze, and browse. As we move through our lives, we should regard these other sentient beings – organisms that contribute to a healthy environment – as neighbours and kin. And although creatures like the Alpine ibex currently have no vote in our society, it is our duty to vote and take action on their behalf.

Wild goat species are an important link in the connectivity chain of a landscape. They remind us that, as a human species, we should strive to address the negative impacts we cause.
