- [Narrator] To film tiny animals,
"Big Little Journeys" needed the help of scientists
and local people working at the forefront of conservation.
- Wow. - Oh wow.
- [Narrator] In Taiwan, the team work with Dr. Nick Sun,
who has tracked critically endangered pangolins
for the past decade.
- When she walks away. - Yes.
- Okay. - Okay.
- [Narrator] Nick gives the team an opportunity
to get a pangolin's eye view of the world,
and it's one that's full of danger.
- [Narrator] Globally, 300,000 pangolins are poached
every year for their meat and scales.
Only in Taiwan is their population stable,
but they still face very real threats.
- [Paul] Pangolins are animals
that I've wanted to film for years,
and then you come to a rescue center
and you see the reality.
- [Narrator] But it's not all bad news.
Nick is preparing to release a young rescued male.
His return to the wild gives the team an opportunity
to closely film the behavior of this elusive species.
To monitor the progress of released individuals, Nick
and his team conduct regular examinations.
- There's friends in rescue center that are giving
these charming, rare, incredible animals a chance in nature.
And I think we all should be very, very pleased
that people like Nick are out there fighting
to protect the natural world.
- [Narrator] The camera crew are preparing
to film the pangolin's first steps back into the wild.

- [Narrator] 11,000 miles away in Brazil,
the team are filming an animal harder to follow.
A family of golden headed lion tamarinds.
- They really go when they want to.
Like for them, they're not traveling far,
they're just jumping between trees.
But for the crew, we are walking up
and down very steep slopes, very tangled terrain.
- They're super small for a primate and very fast.
You have to imagine the face of a tamarind
is maybe the size of a polar bear's nose.
So keeping that in focus
while they're moving is very tricky.
- [Narrator] Keeping up with them is only possible
because of the work of conservationist, Joanison Vicente
and his team who are using radio colors
to track their movements.
(speaking in foreign language)
- [Narrator] 88% of the Atlantic forest has been cut down,
so understanding how lion tamarind's travel is essential
for their conservation.
(animals calling) (leaves rattling)
- [Elsa] It's been little journeys for them.
They're just pinging across the top of the trees.
They've kept us on our toes.
- Come on, let's follow.
(leaves rattling)
- [Narrator] In Taiwan, the team are filming
in a thick bamboo forest.
- I'm hoping the pangolin isn't just gonna run away from us
because it's quite difficult to move around in here.
(leaves rattling) (orchestral music)
- [Team Member] We've just gotta work really calmly
'cause we can't startle him.
If we do, he'll just roll up into a ball.
- [Narrator] It's not just working at the pangolin's pace
that makes filming a challenge, it's also the weather.
(thunder rumbling)
- It's a bit soggy now. I'm feeling a bit soggy now.
- Don't worry.
- We only have a very narrow period of time
where it's light enough to film and the pangolin is awake.
(raining pouring)
(birds chirping)
- [Narrator] In Brazil, the lion tamarinds
lead the team to a kabruka.
Here, local farmers use traditional techniques
to grow shade loving crops
whilst preserving the natural habitat for wildlife.
But Joanison has other ambitions.

(animals calling) (dramatic synth music)
- [Narrator] As the lion tamarins settle
into their new home, the team switched
to remote controlled cameras.
(dramatic orchestral music)
- Each night they're coming back to sleep in tree hollows.
We've found that most nights they're sleeping
in the same one, but sometimes they do catch us out.
- [Narrator] With the support of local communities,
the future is looking brighter
for golden headed lion tamarinds.
(calming ambient music)
(air whooshing)
In Taiwan, the team's time filming pangolins
is coming to an end.
(dramatic synth music)
But by using camera traps and attaching a tag,
Nick can continue to monitor his behavior.
(dramatic synth music)
(speaking in foreign language)
- [Narrator] Pangolins are the most trafficked mammal
on earth, so every release is a victory.
- There is hope for many of these endangered species.
All it needs, passionate people who wanna make a difference.
(speaks in foreign language) - Bye bye.
- There's people like Nick that are really helping to ensure
that these amazing creatures live out here
in the world that they belong in.
So yeah, it's amazing to see.
