Geographic Range
Capra pyrenaica is found in the Carzorla-Segura and Eastern Sierra Nevada mountain ranges on the Iberian Peninsula, Spain. (Grzimek, 1990)
Biogeographic Regions:
palearctic
(native
).
Habitat
(2624 ft)
Spanish ibex live in mountainous terrain generally above 800m. They prefer forested areas with rock outcroppings, coniferous trees, and deciduous trees (including Holm oaks). Forests with multiple strata in the canopy are preferred. The lower canopy strata provide shade cover to escape heat during mid-day. (Escos, 1992)
These animals are found in the following types of habitat:
temperate
.
Physical Description
(77 to 176 lbs; avg. 126.5 lbs)
(39.37 to 55.12 in; avg. 47.24 in)
Spanish ibex are generally brownish to grayish in color. They measure about 65-75cm tall at the shoulder, are 100-140 cm long, and weigh 35-80 kg. Tail lenghth is 10-15 cm. Males are larger than females. Both sexes have horns. The horns of males are much larger and better developed than those of females. Horns of the males reach 75 cm or more in length and curve back over their heads. (Grzimek, 1990)
Some key physical features:
endothermic
; bilateral symmetry
.
Reproduction
mating occurs from November through December, and females typically gice birth in mid-May.
Males compete to mate with females by head butting.
Mating systems:
polygynous
.
Breeding occurs from November through December, peaking in the first half of December. Females in estrus signal to males that they are ready to mate by producing certain pheromones. during the rut, males battle with each other for the right to mate by butting heads. The gestation period of C. pyrenaica is 161-168 days. The peak birthing period is in mid-May. Females breed every year and typically have 1-2 young per year. Females often find a remote, inaccessible location with thick brush for birthing. After giving birth, females and young congregate in groups. Males are full grown and reach sexual maturity at age three. Females are full grown and reach sexual maturity at age 1.5. (Alvarez, 1990; Alados, 1988; Grizmek, 1990)
Key reproductive features:
seasonal breeding
; gonochoric/gonochoristic/dioecious (sexes separate); sexual
; fertilization
(internal
); viviparous
.
Females care for the precocial young (Nowak, 1990)
Parental investment:
altricial
; female parental care
; post-independence association with parents.
Lifespan/Longevity
Spanish ibex can live 12-16 years in the wild. (Grzimek, 1990)
Behavior
Spanish ibex exhibit herding behavior. Males and females with young are segregated into separate groups during most of the year. The young of the year generally travel in the center of the group for protection from predators. Females tend to be solitary during the birthing season, but join the herd latter. In the fall, mixed sex herds of adults separate from mixed sex herds of juveniles. In the adult herds, one dominant male and up to several subordinate males associate with multiple females. There is a strict dominance of hierarchy among the males, and only the dominant male breeds. The dominant male defends his territory and herd of females from other males. Males form the hierarchy and defend their territory by aggressive posturing and fighting by butting heads. After the breeding season, the adults again segregate into herds of males and females. (Grzimek, 1990; Alvarez, 1990)
Key behaviors:
motile
; territorial
; social
; dominance hierarchies
.
Food Habits
Spanish ibex feed primarily by browsing. Their main forage is Holm oak (Quercus ilex). They browse these oaks as well as feed on the acorns. They also feed on forbs (5% of diet) and grasses (10% of diet). Forage of forbs and grasses is selected more in spring and early summer. (Garcia-Gonzales, 1992; Martinez, 1988)
Plant Foods:
leaves; seeds, grains, and nuts.
Predation
- eagles (Accipitridae)
- foxes (Vulpes)
Adult Spanish ibex have no natural predators except humans. The young are susceptible to predation by eagles and foxes. When danger is detected, usually by sight or smell, an alarm whistle is given and the herd flees in columns led by an adult male or female. (Grzimek, 1990)
Ecosystem Roles
Because of its feeding behavior, C. pyrenaica influences succession of plants in its habitat. It also is a primary consumer, converting the energy stored in plants to a form which is then available to its predators.
Key ways these animals impact their ecosystem:
creates habitat.
Economic Importance for Humans: Negative
Spanish ibex potentially compete with grazing livestock. (Gortazac, 2000)
Economic Importance for Humans: Positive
Spanish ibex are prized as trophy game animals. The flesh is considered a delicacy. They are important for tourism, bringing many people to the parks on the Iberian Peninsula. (Grzimek, 1990)
Ways that people benefit from these animals:
food
; body parts are source of valuable material; ecotourism
.
Conservation Status
IUCN Red List: [link]:
Lower Risk - Near Threatened.
US Federal List: [link]:
Endangered.
CITES: [link]:
No special status.
Conservation efforts are being focused on habitat preservation and restoration and looking at competition with introduced species such red deer, like those introduced into Carzorla-Segura park. (Grzimek, 1990)
