Marker

Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since raising the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontories, unlike many modern lighthouses. The most famous lighthouse structure from antiquity was the Pharos of Alexandria, Egypt, although it collapsed during an earthquake centuries later.

The Bushbuck is a close relative of the Kudu and the Nyala. The rams are very elegant in appearance, sporting dark greyish-brown fur, with white spots on the flanks and prominent white socks. In height they are 700 mm at the shoulders, and have a maximum mass of 54 Kg’s. Ewes are smaller and adult ewes are lighter in colour than rams, with more pronounced white spots and stripes. Both males and females have geometrically shaped white patches or spots on the most mobile parts of their body, namely the ears, chin, tail, legs and neck, as well as a band of white at the base of the neck. On males these markings become more visible during their displays when they arch their backs and slowly circle one another, walking in a tense, high-stepping gait. These highly ritualized displays usually make fighting unnecessary and alongside this, a rigid age-based hierarchy among keeps males in check.
