About Gazella cuvieri (Ogilby, 1841)
Cuvier's gazelle (scientific name Gazella cuvieri) is one of the darkest and smallest species of gazelle. It stands 60–69 cm (1.97–2.26 ft) tall, with an average weight of 35 kg (77 lb). A key identifying feature of this species is a distinctive wide, dark band that runs along the sides of its body, separating the brown upper (dorsal) body from the white lower (ventral) body. Cuvier's gazelles have long, slender ears. Both sexes have horns that measure 10 to 15 cm (3.9 to 5.9 in) long, but males have more ribbed, heavier horns. The dark side bands work as part of countershading: lighter ventral fur paired with darker dorsal fur counteracts the shadow created by the animal's own body. This gazelle lives in the Atlas Mountains of Northwestern Africa, across many different landscape types. It prefers sandy or stony hills and plateaus, and also occupies regenerating forests and lush pine forests. Cuvier's gazelles leave the mountains to graze in low grasslands during early morning and late evening. In the afternoon, they travel back up the mountain into forests to find a cool spot to rest for the rest of the day. Cuvier's gazelles breed in winter, and have a gestation period of around 160 days, so they give birth in early spring. Before giving birth, a mother separates from her herd to give birth, then hides the newborn in thick underbrush outside the herd, returning only occasionally to nurse it. This routine continues for the first month, until the newborn begins eating vegetation, though it still gets nourishment from its mother. Cuvier's gazelle is one of the few gazelle species that frequently gives birth to twins, with 40.5% of births producing twins. On average, singlets weigh 2.99 kg (6.59 lb), while twins weigh an average of 2.85 kg (6.28 lb). Females can breed again just ten days after giving birth, allowing them to produce two sets of offspring per year. Female newborns can become fertile as early as 27 weeks old, and can give birth for the first time as early as 70 weeks of age.
