At 97, Sir David Attenborough is a man still happy to crawl on his belly through wet grass to get his shot.
For his latest Sky Nature project, Secret World Of Sound, the world-renowned naturalist and broadcaster explores the ways that animals hear and produce sound, using cutting-edge technology to record noises from nature – with some captured on film for the first time.
Attenborough’s long-time collaborator, and the show’s series producer, Sharmila Choudhury tells The Climate Show: “David keeps us on our toes. He sets the bar very high. And that’s a good thing.
“I think he work still works harder than most of us, usually seven days a week… When he commits himself to something, he gives it 100%.”

Joining the team for filming in the Wye Valley in Monmouth to capture the song of a wild dipper, Attenborough found himself lying on the damp ground hoping that the small bird would show up.
Truly at one with nature, he didn’t have long to wait.
Choudhury explains: “He crawled through the grass to get into the best position, and was all up for it… We didn’t want to leave him lying in the wet grass for hours.

“Miraculously, and this often happens when David arrives on location, the sun suddenly burst through the clouds.
“The dipper flew in. David smiled and delivered his lines of what he wanted to say, you know, smoothly in one go. It’s amazing.”

‘It hits you in the core’
For the same episode, Attenborough explains how bees are struggling with modern fertilisers and climate change.
Choudhury says: “Him looking straight to camera and delivering a message like that is so powerful. It literally hits you in the core.”
Calling him an “inspiration,” and praising his “unrivalled” breadth of knowledge, she adds: “And he obviously has a fabulous voice and style of delivery, which is the cherry on the cake of any natural history program.”
A three-part series, the documentary studies animal behaviour, breaking the sounds they make down into four functions – finding a mate, looking after young, hunting for food or avoiding becoming prey.
Technology worthy of 007
Some of the technology used in the series was borrowed from other walks of life, while other bits of kit were of true James Bond status.
Choudhury says: “We used everything from the tiniest microphone the size of your fingernail, that you could put inside a bird nest or a beehive, to super sensitive hydrophones that you can put underwater to record, the faintest communications between fish.
“There were also a couple of, gadgets that were actually developed for other industries – the gas industry, or for espionage purposes, that we thought might help us to listen in on sounds that we don’t normally get to hear.”
One of those gadgets was the laser vibrometer – a machine which shoots out a laser beam to detect any vibrations caused by noise and amplifies them, so they are audible to the human ear.

It was used to capture the love song of a pair of amorous treehoppers in Costa Rica.
While sound was the focus of the documentary, another theme became impossible to ignore while filming.
‘Every single shoot was impacted by climate change’
Choudhury says: “The biggest challenge, without any doubt, was climate change. It’s something that we’ve seen creep in on us over the years.
“I’ve been making wildlife films for over 30 years. And in the last decade or so, more and more shoots have been impacted by climate change.
“That means animals that would have been predictable in their movements, say, their migrations or where they would be, or the time of year they’d be breeding, are not doing the usual things anymore.
“It started off with one or two parts of the world, or one or two shoots being affected by this. But on this particular series, every single shoot was impacted by climate change.
“That made filming very difficult, and it was very distressing to see the animals suffering in this new world.”
‘The elephants were so stressed’
One example was the team’s trip to Amboseli National Park in Kenya to film elephants.

The plan had been to shoot a story about how mothers and babies communicate with each other – but when they arrived following Kenya’s worst drought in 40 years, they found the elephants in an awful plight.
“The elephants were behaving very differently to before. They had split up into tiny herds and every night they would go out of the park to surrounding fields to try and find some food.
“Every morning they would walk back into the waterhole in the middle of the park, and they would walk single file heads down, absolutely dejected. They didn’t make a single sound.
“The animals were so stressed, they had no energy left to talk to each other effectively.
“After we left, Kenya and Amboseli experienced the worst deaths of wildlife, including elephants, recorded history and that was clearly a result of climate change.”

‘Buy the coral reefs a little time’
But there was some hope amid the devastation being caused to the natural world by the climate crisis – and this was very much set in the world of sound.
During filming, the team discovered an Australian scientist whose research had found that by playing the sound of a healthy coral reef at the site of a dying reef it could help regenerate it and bring back some of the fish.

Choudhury explains: “They are hopeful that they might be able to buy coral reefs a little bit of time whilst we tackle climate change.
“It won’t be a solution in the long run because the reef will continue to die off if the oceans continue to warm. But it’s a little ray of hope, at a time when we so badly needed.”

Secret World Of Sound With David Attenborough is streaming on Sky Nature and NOW.
CCTV images have been released of a jailed asylum seeker who was accidentally freed from prison – as police detailed the last sighting of him.
Hadush Kebatu was released in error from HMP Chelmsford on Friday instead of being handed over to immigration officials for deportation – one month into a 12-month sentence.
As the manhunt continues, the images show him in the Essex town on Friday and later the same day in Dalston, east London, where he was carrying a “distinctive white bag with pictures of avocados on it”, said the Metropolitan Police.
The last sighting of Kebatu is thought to have been in Dalston CLR James Library in Dalston Square on Friday evening.
The Ethiopian national had been found guilty in September of sexually assaulting a 14-year-old girl and a woman in Epping.
His crimes while staying at The Bell Hotel in Epping sparked weeks of protests over the summer.

Police call on public to assist on manhunt
The Met Police, which has been leading the search for Kebatu, alongside Essex Police and the British Transport Police, has made a direct appeal Kebatu to hand himself in.
He left Chelmsford train station at 12.42pm on Friday and arrived at Stratford station in east London soon after at 1.12pm.
Kebatu had since taken “a number of journeys” across London and had “access to funds”, according to Met Commander James Conway.

Last sighting
The force said he was last seen shortly before 8pm on Friday evening in the Dalston area of Hackney in east London.
It has released two CCTV images of him from Friday, one in Chelmsford where he was wearing his prison-issued, grey tracksuit and holding a clear, plastic bag containing his possessions.

The other was taken in Dalston, where he was still wearing his grey tracksuit, but was carrying his belongings “in a distinctive white bag with pictures of avocados on it”.
A Met statement added: “Additional officers have been deployed to the area to carry out further searches, but we are appealing for the help of local residents to report any sightings as soon as possible.”
Mr Conway has asked for members of the public who have given assistance to Kebatu to contact them or anyone who sees him to call 999.
And in a direct appeal to Kebatu, Mr Conway added: “We want to locate you in a safe and controlled way.
“You had already indicated a desire to return to Ethiopia when speaking to immigration staff, the best outcome for you is to make contact directly with us by either calling 999 or reporting yourself to a police station.”

The witness, called Sim, said Kebatu came out of the jail saying, “Where am I going? What am I doing?” and hanging around for about 90 minutes as he tried to find out where he should be going.
Sim said the offender returned to the prison “four or five times” but was turned away.
He said Kebatu knew he should be deported but the prison staff were “basically sending him away” and saying to him, “Go, you’ve been released, you go”.

Kebatu was spotted later in Chelmsford town centre asking for assistance before getting on a train to London.
HM Prison and Probation Service is introducing new and mandatory procedures for prisoner releases after Kebatu was mistakenly freed, Ministry of Justice sources say.
Duty governors, who are responsible for the daily secure operation of prisons, will now be required to complete additional checks the evening before a release, it is understood.
Governors will need to provide assurance that the procedure is in place on Monday, Sky News understands.
Justice Secretary David Lammy said on Friday night that Kebatu was “at large in London”. He said he was “livid on behalf of the public” and added that he had launched an investigation.
Sir Keir Starmer said he was “appalled” at the accidental release and said it was “totally unacceptable”, adding: “This man must be caught and deported for his crimes.”
A prison officer has been taken off duties to discharge prisoners while an investigation takes place.
Former Commons leader Lucy Powell has been crowned Labour’s new deputy leader in a closely fought race against Education Secretary Bridget Phillipson.
Ms Powell received 87,407 votes to Ms Phillipson’s 73,536 – a majority of 13,871 – in a contest that was widely perceived as a referendum on Sir Keir Starmer’s popularity with the membership.
Ms Powell was seen as the “anti-Starmer” candidate given she was sacked from cabinet just last month, and centred her campaign on being an independent voice for the backbenches.
Ms Phillipson was seen as Number 10’s preferred option, and she had pitched herself as the “unity candidate”, warning that voting for her opponent would result in “internal debate and divisions that leads us back to opposition”.
However speaking to Sky News’s political editor Beth Rigby following the result, Ms Powell insisted she would be a “friend” to the prime minister, adding: “I am confident we can work well together.”

She said she was not here to “write an alternative policy platform” but rather “to make sure Labour values and beliefs are right at the heart of the conversation, and that we’re giving a really clear sense of who we’re for”.
Ms Powell’s earlier victory speech made clear where she thought Labour was going wrong, and what she would challenge the government on.
The Manchester Central MP said Labour “won’t win by trying to out-Reform Reform, but by building a broad progressive consensus”.
She said that started with “wrestling back the political megaphone” from Reform leader Nigel Farage, and “setting the agenda more strongly”.
“Let’s be honest, we’ve let Farage and his ilk run away with it. He wants to blame immigration for all the country’s problems. We reject that,” she said.
“Our diagnosis is different, that for too long the country and the economy has worked in the interests of the few, not the many.”
The reference to “for the many not the few” – the slogan during Jeremy Corbyn’s time at the helm, was not lost on his then shadow chancellor John McDonnell.
The veteran left-winger said on X: “The Labour Party members have spoken & the message is clear, they want change. It’s good to see a return to references to the Labour Party serving once more the many not the few & that Labour must not try out Reform, Reform. Our members realise a new start is desperately needed.”

The scandal sparked a reshuffle in which Ms Powell was one of the only casualties. It makes the new partnership potentially very awkward for Sir Keir, especially as his new deputy will be free to speak out against his policies from the back benches rather than being bound by collective responsibility like Ms Phillipson.
However in a possible olive branch, Sky News understands Ms Powell will be asked to attend political cabinet meetings, even though she will not officially be a member of cabinet.
Tory chairman Kevin Hollinrake said “weak Keir Starmer” has had an unwanted deputy leader “imposed on him by the Labour Party”, adding: “The failure of the Keir Starmer candidate, Bridget Philipson, is another defeat of the prime minister’s authority.”
Turnout for the vote was low – just 16.6%, suggesting a lack of enthusiasm among party members and its affiliates.
Sir Keir congratulated Ms Powell after the results were announced, saying she “has always been a proud defender of Labour values, and that is exactly what we need at this moment”.

PM: Powell is ‘a proud defender of Labour values’
He echoed some of her language around immigration, as he attacked the Tories for this week suggesting they supported a policy to deport people who have settled in the UK legally, something Reform UK has advocated.
“That is what we’re up against on the right of politics, a politics of division and grievance that wants to take this great country to a very dark place”, Sir Keir said.
PM warns of ‘battle for the soul of our nation’
The prime minister is under pressure as the party plummets in the polls, with many MPs on the left predicting he could be gone by May if the local elections go badly.
He said it was a “bad result” and “a reminder that people need to look out their window and see change and renewal in their community, opportunities for their children, public services rebuilt, the cost of living crisis tackled”.

Phillipson ‘disappointed to lose’
“We must unite. We must keep our focus on what is, in my view, the defining battle for the soul of our nation. I know that Lucy will do just that,” he said.
Saturday’s result is the culmination of a six week contest, with the pair having had to secure nominations from 80 MPs in the first round and then win the backing of 5% of local parties or Labour affiliated groups before making it to the final vote.
The manhunt for a migrant who sexually assaulted a schoolgirl, and was released from prison in error, is ongoing.
Hadush Gerberslasie Kebatu was jailed for 12 months earlier this year after he sexually assaulted a 14-year-old girl and a woman in Epping.
He had been staying in the Bell Hotel in Epping and his arrest triggered large-scale protests and disorder.
The Ethiopian national, who came to the UK on a small boat in the summer, is now being searched for by the police after he was accidentally freed on Friday.

How many prisoners are released in error?
According to government statistics published in July, 262 prisoners were released in error in the 12 months to March 2025 – a 128% increase from 115 the previous year.
More from UK
The report states: “Of the 262 releases in error, 233 of these releases in error occurred from prison establishments, while 29 were released in error at the courts.
“Releases in error from establishments could also be a result of errors by the court.”
This is out of a total prison population across England and Wales of roughly 86,000.
Sky News has contacted the HM Prison & Probation Service to know how many of the 262 prisoners have since been found and returned to custody.
In September 2024, Sky News reported how dozens of people released from jail under the government’s emergency prison scheme were freed by mistake.
The Labour government said it was forced to release hundreds of inmates early because prisons were at capacity.

Kebatu, who is thought to be in the London area, was due to be deported when he was mistakenly released from HMP Chelmsford on Friday.
Previous high-profile manhunts
William Fernandez, who was awaiting trial for sexual assault, was released from HMP Wormwood by error in March 2021. He then went on to rape a 16-year-old girl and sexually assault a young woman.
