Blue Duiker

Philantomba monticola

Blue duikers form monogamous pairs that defend permanent forest territories, marking shared boundaries with secretions from prominent facial glands beneath their eyes. These diminutive antelopes shadow troops of monkeys and canopy birds to glean fallen fruit, flowers, and tender leaves knocked to the forest floor. When startled, they utter a sharp, whistling sneeze and plunge instantly into dense underbrush with rapid, diving leaps.
