White #rhinos are famously grazers (grass-eaters), and have wide square lips to help them crop short grass, while black rhinos have pointed lips for browsing on shrubs, BUT... here we have some rule-breaking white rhinos clearly browsing shrubs. 🦏🌿 #MammalWatching #SouthAfrica

The klipspringer should be everyone's favourite #antelope: they're the size of a small dog, have the face of a teddy with tiny spike-horns, and they walk on the tips of cylindrical hooves that grip the rocks they live among (their name means "rock-jumper" in Afrikaans). #MammalWatching #SouthAfrica

It's amazing that perhaps the world's best place to see an awesome wild cat - the caracal - is right on the edge of a big city. Climbed #TableMountain today from #CapeTown with a tiny hope of seeing one, & was delighted to find some poo. Half the joy of #MammalWatching is just knowing they're there

Meet the bontebok, an #antelope that is only found in the fynbos habitat of the Western Cape of #SouthAfrica. All surviving bonteboks are descended from a population of just 22 individuals, which were saved in 1931 by being fenced into the newly created Bontebok National Park. #MammalWatching

Natural history #museums in the Northern Hemisphere all highlight giant deer, and in #SouthAfrica, they had a giant buffalo, with horns that were 3 metres across. They died out only 4000 years ago. 🐮📏↔️

THE FIRST FOSSIL MAMMAL
FROM SOUTH AFRICA

The African giant buffalo is the largest bovid ever described from
Africa. It was a larae animal, weiahina 1800 ka, with horns that
measured 3 m from tip to tip and was such an impressive find that
Charles Darwin presented this fossil to the Geoloaical Societv of
London in 1839

Unlike the other extinct animals on display, humans were around
to watch this giant roam the African grasslands and savannahs
but sadlv due to a combination of hunting and changing climates,
this animal went extinct around 4000 years ago.

The hyrax life: lounging around on rocks, bathing in the sun in spots that predators aren't likely to get you. Despite looking like a cross between a chubby #rodent and a seal, hyraxes are actually more closely related to #elephants - part of the Afrotheria mammal group. #MammalWatching #SouthAfrica

I'm late to the party, but @andreawulf.bsky.social's masterpiece is utterly brilliant. I knew almost nothing about Humboldt, but his impact on how we see nature in the West - both ecologically and emotionally - was nothing short of immense. But more than that, the story is brilliantly told. Read it!
