A female gerenuk (a name derived from the Somali language meaning 'giraffe necked') in the Samburu National Reserve of Northern Kenya. Their long necks and large ears distinguish them from other gazelles. Only females do not have horns. Strictly browsers, gerenuk can often been seen feeding on branches six feet high by standing on their wedge-shaped hooves, supported by their strong hind legs.Well adapted to semi-arid lands, they can withstand waterless conditions with ease.   .
