He also watches vast numbers of wildebeest and zebras run the gauntlet of gargantuan crocodiles as they cross the Mara River on migration. Finally, he has the frustrating experience of losing contact with Amber the cheetah and her family as they disappear into wild country.Jonathan Scott has good news about Half-Tail the leopard: she looks as if she may be a mother once again. He also sees a lioness drag a 150 kilo wildebeest into cover using her teeth - a feat of incredible strength.
