The inside of a termite mound proved especially challenging for Attenborough: it was so cramped that he could only face in one direction. He therefore had to slowly crawl backwards out of shot when performing re-takes.
The wild dogs of Luangwa Valley are organized, tenacious and strictly hierarchical under the leadership of an alpha pair. While cheetahs sprint and lions ambush, wild dogs rely on their stamina to wear prey out, sometimes running up to 20 miles at a time. But to maintain dominance, they'll need to train their youngest members to hunt effectively as part of the pack-and time is running out.
This episode details the relationship between flowers and insects. There are some one million classified species of insect, and two or three times as many that are yet to be labelled. Around 300 million years ago, plants began to enlist insects to help with their reproduction, and they did so with flowers. Although the magnolia, for instance, contains male and female cells, pollination from another plant is preferable as it ensures greater variation and thus evolution. Flowers advertise themselves by either scent or display. Some evolved to produce sweet-smelling nectar and in turn, several insects developed their mouth parts into feeding tubes in order to reach it.
From earthquakes to tsunamis to volcanic eruptions, natural disasters are both terrifying and fascinating - providing endless fresh material for documentary makers. But how well do disaster documentaries keep pace with the scientific theories that advance every day? To try and answer that question, Professor Danielle George is plunging into five decades of BBC archive. What she uncovers provides an extraordinary insight into one of the fastest moving branches of knowledge. From the legendary loss of Atlantis to the eruption that destroyed Pompeii, Danielle reveals how film-makers have changed their approach again and again in the light of new scientific theories. While we rarely associate Britain with major natural disaster, at the end of the programme Danielle brings us close to home, exploring programmes which suggest that 400 years ago Britain was hit by a tidal wave that killed hundreds of people, and that an even bigger tsunami could threaten us again.
At 13, Kamuti is one of the oldest leopards in the Luangwa region of Zambia. Old age brings many challenges, from hunting antelope to keeping a watchful eye on the lion pride nearby. Using a military-grade thermal camera, we lift the veil on the secret world of this enigmatic nocturnal predator for the first time.
