Within the seemingly organised and wonderful world of birds, there lurk cheats and baddies; birds that knock the system and get away, not with murder, but without lifting a finger (nor even a wing) to help with the bringing up of their offspring. These are the brood parasites, the birds that do not make their […]
Heterodontosaurus was one of the smallest dinosaurs, about half man-size. It often walked on its hind legs, and its three-toed footprints can be found in the Cave Sandstone surrounding The Cavern. “Heterodont-“ means having teeth of more than one design – unusual in anything other than a mammal. Some individuals, presumably males, had pointed “canines”,
Next time you are sitting peacefully at the edge of one of the many Cavern dams – either admiring the tranquil beauty around you, or maybe fretting at the lack of fish bites – have a closer look at the lovely dragonflies flitting so effortlessly about you. The first thing to note is that there
The Drakensberg has dramatic scenery, but a relatively simple structure. Except for the lowest slopes, the whole of the Berg is made up of only two rocks. From 1500 metres altitude (The Cavern) up to about 2100 metres is the Cave Sandstone. It forms conspicuous pale yellow-brown kranzes capped by an undulating plateau – the
The Zulu and Xhosa word for the moon is inyanga which is thought to be of Khoi-khoi origin. Whereas Europeans have traditionally talked about a “man on the moon”, the Zulus and other African tribes see a woman carrying a bundle of sticks. A Zulu tale tells that meteors (or shooting stars as they are
The scientific names of plants can be very daunting – a strange, unspoken language that we often reject as far too difficult. But with a little explanation they become interesting and very informative. More often than not the generic name is of Greek origin and the specific name from Latin. Take for example the Cheesewood
Everyone knows that summer is the best time for birds. Migrants come from all over the world to join the hardy residents. Winter, by comparison, seems almost birdless, especially as the residents have given up singing. Its dry cold may seem daunting, but it actually brings in birds from other areas where winters are worse.
As Summer slowly quietens into Autumn, so the birds too slide gently from the frantic frenzy of being a parent to the more decorous state of grandparent-hood. The season’s young have been packed off to fend for themselves as best they can, and the parents can now potter about satisfying only their own simple needs.
Many animals scarcely show themselves at all, and when they do it is at night. Incidentally, long ago, when all mammals were small, they had to be nocturnal to avoid dinosaurs. Our warm-blooded condition today has its origins then, when mammals had to withstand the cold of night. One of the best ways to detect
The month of June seems filled with shivery winter days – I am so glad that mid-winter has now passed by and there in the not too distant future lurks that wonderful season called spring! I wonder if the birds feel the bite of cold as they hop about on frozen spindly legs, searching for
