The Best Episodes Directed By Katrina Bartlam

The series opens in Africa's south west corner and features the wildlife and landscapes of the Kalahari and Namib deserts. Starlight cameras reveal previously unfilmed nocturnal behaviour of black rhinos as they socialise at a Kalahari waterhole, and super slow motion footage captures a fierce battle between two male giraffes. Other sequences show Namibia's famous and mysterious fairy circles, how a fork-tailed drongo's talent for mimicry allows it to steal a meal from a meerkat clan, how ostrichs help their chicks find water, and how red-billed queleas defend their nests from marauding armoured bush crickets. Also, for the first time, cameras enter the world's largest underground lake in Dragon's Breath Cave and film the critically endangered golden cave catfish. Eye to Eye looks behind the scenes of the rhino and giraffe filming.

The penultimate episode opens in the cedar forests of the Atlas Mountains, where Barbary macaques have become isolated from other primates by the expanding Sahara. Aerial photography shows the Sahara is a landscape dominated by rock. Animals featured include Grévy's zebra, addax and naked mole rats, each found on the desert's fringes. Two million barn swallows are forced to cross the Sahara on their migrations, congregating at a poisoned oasis to feed on flies. The last remaining freshwater pools are home to stranded desert crocodiles, filmed hunting tilapia fish. Macro photography reveals the struggles of dung beetles and silver ants, the latter able to survive exposure to the brutal midday sun thanks to their reflective body coating. Eye to Eye shows how an 18-month time lapse sequence of Libya's sand dunes was filmed.
