He's been making nature documentaries for seven decades, but Sir David Attenborough is showing no signs of slowing down. 

The broadcaster and biologist, 99, has bagged two 'magical' BBC projects ahead of his 100th birthday - despite worries from fans he'd soon stop making new series. 

Sir David will turn his attention closer to home for the first project, Wild London, which sees the natural historian exploring the wildlife of the city he's lived in for 75 years. 

The cameras will follow pigeons commuting by tube, snakes on Regent's Canal, a family of foxes living in the heart of Tottenham, and peregrines nesting along the Houses of Parliament, according to The Mirror.

Wild London's executive producer Tom Hugh-Jones told the publication: 'Wild London captures that Attenborough magic at its very best - presenting in vision throughout the film, having up-close encounters with animals and talking intimately about his own wildlife experiences.' 

Meanwhile, the broadcasting veteran, who turns 100 next May, has already been confirmed to be narrating a new natural history series, Kingdom.

The six-part show will follow the real-life trials and tribulations of four African animal families in Zambia. 

Filmed across five years, animals due to make an appearance include leopards, hyenas, wild dogs and lions, as they fight for survival in their remote riverside home.

The series' producer Felicity Lanchester teased: 'With David’s commentary the Kingdom series really sprung to life - a wry inflection here, warmth in his voice there and masterful dramatic timing around the action. 

'He tells the story in the clearest, most compelling, and emotional way. We are so grateful for his involvement.'

Elsewhere, Green Planet II, a follow-on from the original series that aired in 2022 that took a deep-dive into plant life, is also set to return to BBC One. 

And Tiger Island, a two-part series about an island near Nepal where tigers - an endangered species on the brink of extinction - appear to be thriving.  

BBC factual boss Jack Bootle said of the upcoming nature-focused programming: 'No other broadcaster invests so consistently in wildlife filmmaking or covers such an ambitious range of subjects and styles.

'From David Attenborough exploring the wildlife of his own city, to a team of intrepid filmmakers risking it all to document the secret lives of tigers in Nepal. 

'I’m proud we continue to lead the way at a time of such uncertainty for our planet.'

It comes after it was revealed that Sir David was set to be the latest TikTok star unveiled by the BBC. 

The natural treasure was hailed as the perfect front man for short clips on the social media site by the broadcaster's director general Tim Davie. 

According to The Sun, Tim revealed that segments of Sir David's programmes are likely to be made into new bite-sized videos that Gen Z viewers can watch online. 

'I think what doesn’t work is a massive lurch to youth and trying very hard to be the coolest one on the block,' he told the House of Commons Public Accounts Committee. 

'Who is incredibly popular with young people? Our 99-year-old natural history presenter, who is a legend who they trust.

'The key thing is to be trusted, and to be absolutely speaking with authenticity.

'I do believe you can do a two-minute thing on TikTok, but actually make sure it meets the BBC’s editorial values.

'That is not dumbing down if you do it right; it just may not be to everyone’s taste.'

Earlier this year, fans were left concerned that Sir David might be stepping back from his time in front of the camera, as he revealed he was 'nearing the end of his life'. 

He became reflective about his own mortality as he discussed the state of the world's oceans in the film Ocean: With David Attenborough, which was released to coincide with his 99th birthday on May 8. 

Harrowingly looking to a future without him in it, he remarked: 'When I first saw the sea as a young boy, it was thought of as a vast wilderness to be tamed and mastered for the benefit of humanity.

'Now, as I approach the end of my life, we know the opposite is true. After living for nearly a hundred years on this planet, I now understand that the most important place on Earth is not on land, but at sea.'

He added: 'Today, it is in such poor health I would find it hard not to lose hope were it not for the most remarkable discovery of all.'
