My Halcyon River

An idyllic British river: misty dawns, dancing mayflies, lazy trout and fluffy chicks paddling under the watchful gaze of their parents. "My Halcyon River" is an intimate portrait of a secret world where otters hunt on the midnight current, mink lie in wait to ambush unwary victims and gleaming kingfishers pierce the water to spear their prey. These dramas, both mortal and touching are revealed through the eyes of a man who has loved the river since he was a boy, cameraman Charlie Hamilton-James.

Wild Women of Viramba

Almost every day for the past 25 years, the Viramba troop of yellow baboons have been accompanied by scientists in one of the most extensive primate research projects ever conducted. Researcher Holly Carroll has come to understand the troop, which is controlled by its female members. She discovered that they had established a strict hierarchy in order to keep daily life running smoothly. Interestingly, female offspring automatically inherit their mother's rank. Research into the lives of these 'wild women' of Viramba shows that living in a group can work if all members cooperate. Life in Mikumi National Park is certainly not easy but their inherited hierarchy means there is little need for these baboons to fight.

The elephant, the Emperor Moth and the Mopane tree form the backbone of life on the African plains. This delicate ecological triangle determines the livelihood of all the other creatures in its system. The Mopane tree is under attack from rampaging elephants, but even more damaging is the Mopane worm, the caterpillar of the beautiful Emperor Moth. They gather in hoards and strip the trees of their leaves in minutes. But the worms are food for a host of animals - even humans - and the trees are home to a number of unpleasant creatures.
