Chris and Martha discover which of our tagged bees have survived over the midsummer week - a frenetic nectar and pollen gathering period - and if they have collected enough food at this critical time to see them through the winter. With the help of Prof Adam Hart they will also explore the queen's remarkably deadly mating ritual and look at how bees can help us medically and how we can help them.
Birds owe their global success to feathers - something no other animal has. They allow birds to do extraordinary things. For the first time, a slow-motion camera captures the unique flight of the marvellous spatuletail hummingbird as he flashes long, iridescent tail feathers in the gloomy undergrowth. Aerial photography takes us into the sky with an Ethiopian lammergeier dropping bones to smash them into edible-sized bits. Thousands of pink flamingoes promenade in one of nature's greatest spectacles. The sage grouse rubs his feathers against his chest in a comic display to make popping noises that attract females. The Vogelkop bowerbird makes up for his dull colour by building an intricate structure and decorating it with colourful beetles and snails.
Following the success of Helen Macdonald's bestselling novel of the same name, H is for Hawk: A New Chapter is an intimate and personal journey. After the loss of her father, Helen trained the hardest bird in falconry, a goshawk. The cathartic experience helped her to grieve and now she is ready to do it again, but this time she hopes it will be her wings to somewhere new. In this beautiful and moving film, Helen trains a new bird and follows a wild goshawk family at the nest, getting closer than ever before to these fiery eyed birds of prey.
The Arctic and Antarctic experience the most extreme seasons on Earth. Time-lapse cameras watch a colony of emperor penguins, transforming them into a singleorganism. The film reveals new science about the dynamics of emperor penguin behaviour. In the north, unique aerial images show a polar bear swimming more than 100km. Diving for up to two minutes at a time. The exhausted polar bear later attacks a herd of walrus in a true clash of the Titans.
