After 23 years with the natural history unit at BBC studios, you'd think Jonny Keeling would have witnessed every imaginable animal behavior.
But when describing a sequence from Seven Worlds, One Planet, the executive producer's excitement is palpable.
"We filmed polar bears awaiting the arrival of Beluga whales in North America so they could pounce on them. You get to see [the bears'] exact strategy as they try to outsmart some of the cleverest creatures on the planet."
The camera crew relied on the latest technologies, in this case 30-pound drones, to capture many encounters that had never before been documented.
Shot over a two-year period, Seven Worlds not only reveals how each continent has shaped its own unique animal population, but also the challenges animals face in a modern world.
When selecting stories from a mind-boggling 92 shoots in 41 countries, Keeling looked for sequences that were both emotionally engaging and dramatic. Variety was also key. "You want to have balance in the episode," he says. "Not 10 sequences on predation or mothers caring for their young."
As for managing such a massive undertaking, Keeling notes, "It boils down to two things: you need to be really stubborn and determined, but you also need the sensitivity of an angel, because you're trying to tell emotional stories."
Narrated by world-renowned natural-history filmmaker Sir David Attenborough, each episode includes conservation stories that Keeling believes make the series feel "relevant and contemporary."
He hopes the devastating story of the last two remaining northern white rhinos in Africa (both females), along with more uplifting narratives about species that faced extinction but are now repopulating, will move the series' billion or so viewers worldwide to take action.
"I want them to watch and think you can do something. It doesn't take a big sacrifice."
