In the 1899 Oscar Neuman describes for the first time a new species of chamois, calling it Rupicapra Ornata. It's the Abruzzi chamois, since then confused with the Alpin Chamois.

Now the different between the two species is proved by morphologics and biologics studies. In this last years it's been showed by DNA study: that is the genetic study has confirmed that the Alpin Chamois and Abruzzi chamois are two different species, and that the Rupicapra Ornata belongs to the spanish stock. In fact the Abruzzi chamois and "spanish" chamois are much similars.
The females and the littles live in herd (the males remain there untill 2-3 years from birth and then they begin to wander; these are the individuals that risk more of all the death because they often find itself in unknown places, full of dangers), while the reproductive males (after 8 years from birth) rejoin to the herd for the season-love who start in the first of November. This is the moment of the violents encounters between the males who compete for the right to couple with the females of the herd; after, the winner will protect its harem from the raids of the others males.

The little of chamois come into the world in the first fifteen of May: the females remain in the herd, while the males -after two years- go away to start a solitary life untill the age of reproduction.
The chamois is an herbivorous, bound to the grassland over 2000 m. In the National Park of Abruzzo the festuco-trifolietum thalii (legumineous rich of proteinaceous substances) is the favourite grassland for the females and the littles. Instead the males, having not particular exigences, eat a little of all. The pastures of festuco are small on Majella's mountains and absent on the Gran Sasso's mountains: so we can say that the positive reintroduction on Majella and on Gran Sasso have showed the great adaptability of Abruzzi chamois to the ambient.

It's inured to live in inaccesibles places, above all rocky walls and ledges where they take cover from raids of the predatories. In the summer they live in high mountain, while in the winter they go down, living to the border of the vegetation and prefering south walls where it's less snow and more possibility to find food.

When there is a danger (caused from a predator or a turist), it give a whistle of alarm to warn the intruder to not advance; otherwise it will escape on the steeps rocky-walls.
