Wildebeest actually have "swarm intelligence," enabling them to act as a unit. The herd explores and overcomes obstacles as one. This is not an everyone for themselves operation. The herd succeeds based on collective trial and error. With enough followers the herd is bound to succeed. The key component is that there is a shared vision for the Wildebeest, they are moving from one grazing land to another. All their movements are unified towards achieving the goal that will benefit the entire herd.
Polar bears may be the poster boy of Arctic animals threatened by climate change, but musk oxen are not far behind. Instead of the loose powdery snow that they can usually push aside with their snout and legs, there is a hard layer of ice. When rain falls on top of snow and then refreezes, it forms a hard layer of ice, which the musk oxen cannot break through. While musk oxen may not be quite as charismatic as polar bears, they deserve just as much attention.
What fascinates me about the musk ox is the strength it has to adapt to the most hostile of environments. In the winter, they feed on roots, mosses and lichens buried under the snow and spend over four months without sunshine, in total darkness, surviving in temperatures reaching as low as -60°c.
Once in a lifetime… No more than 13 lionesses and cubs napping and spotting up a tree in Serengeti National Park. There are many theories put forward to explain why lions climb trees. These include avoiding wet grass, getting a cooling breeze, getting a better view of the surroundings. But this pride was spotting a group of girafes 700 meters away.
