In the northeast corner of Botswana, the rainy season is months away. The sausage tree offers a beguiling oasis for wildlife--from birds and insects, to much larger mammals like elephants--all reeling from the dry conditions. Then, as the rains descend, brilliant red flowers bloom and entice parrots, squirrels, and sunbirds to help with pollination. Summer allows the sausage tree to live up to its name, delivering massive, sausage-shaped fruit, a nutritious feast and a cornerstone of life in this exotic ecosystem.
Sri Lanka, the tropical island lying off the southern coast of India, is home to its own special elephants. A subspecies of the Asian elephant, they have their own unique characteristics. In this programme, award-winning wildlife cameraman Martyn Colbeck of Echo of the Elephants fame travels to Sri Lanka to try and get to know them. Martyn has planned his arrival to coincide with the start of the monsoon, hoping it will be the best time to find and follow a newborn calf. By drawing on local knowledge, Martyn begins to unravel the complex social world of Sri Lanka's elephants - he witnesses a fight over a calf, a battle between two bulls in musk and, at an elephant sanctuary, befriends an orphaned elephant who sadly lost a leg to a snare and is facing an uncertain future.
