The Portuguese Ibex "Capra pyrenaica lusitanica" (an extinct subspecies of Spanish Ibex) was a species of mountain goat that inhabited the north mountainous zones of Portugal, Galicia, Asturias and western Cantabria. In size and colouration it was much like the Spanish animals, though inclining towards brown rather than black markings. Its horns were strikingly different from any of the other Iberian subspecies. They were only half the length of the Pyrenean Ibex (about 51 cm or 20"), but were almost twice as wide, and, consequently, much closer together at their base.

Extinction

Until 1800 the Portuguese Ibex was widespread in its range, but thereafter its decline was rapid as hunting pressure increased. Local hunters did not respect the closed hunting seasons and shot Portuguese ibexes when the herds came down to lower altitudes in May. Local people hunted it for its meat and for the bezoar stones in its stomach which were regarded as potent medicine and antidotes for poisons of all kind. The skins were used as coverlets and the horns both as ornaments and as trumpets of alpine horns to call across the narrow valleys of the north-western mountains. By 1870 this ibex was a rare animal. The last herd of about a dozen animals was recorded in 1886. An old female was captured alive in September 1889, but only survived for three days. Two more females were found dead next year, victims of a Galician avalanche. The last known Portuguese Ibex in Spain died in 1890, and the very last known sighting was a female near Lombade Pan in the Serra do Gerês in Portugal in 1892. Nowadays another subspecies, the Gredos Ibex "Capra pyrenaica victoriae" Cabrera, 1911, has been introduced in the former range of the Portuguese Ibex. A specimen was on display in the Museo Bocage in Lissabon until a fire destroyed it in 1978.

Possible causes

Hunting pressure and other human factors are the most likely cause of the extinction. Some scientists have pointed to factors other than human interference that may have affected the decline of the Portuguese Ibex.{fact} Grey wolves and golden eagles, disease from domestic herds and a disproportionate number of males may have contributed to the rapid population decline. The last point seems especially dubious, as the bucks were naturally the most hunted. Additionally, the last recorded sightings were all of females. There is little doubt that the only significant contributing factors were of human origin.
