Morning.

Ricky here with Newsround on Saturday.

First up, more success in the pool as Team GB

bagged their fourth medal in the World Championships

in Hungary.

They won gold in the men's 4x200m freestyle.

GB had three medals from the first five days of competition, all gold,

with two for Adam Peaty.

Next, take a look at this little guy.

He's a hazel dormouse.

Recently, the numbers of these tiny mammals have dropped.

Whitney went to meet the people on a mission to help them.

The hazel dormouse weighs between 18 to 20 grams.

Fruits, flowers, nuts and insects are what they like to eat.

And woodland in parts of England and Wales is where they live.

I've come to these woods in Nottinghamshire where nest boxes

have been put up to help keep dormice safe and it's Ian's job

to help monitor them.

It looks like we've got a dormouse in there in a very deep sleep,

so we can take that off and have a look

and see what that is.

So they go into a large bag just to make sure, if they are active,

that they can't escape, because they are very fast

and very good climbers.

It's in a very deep sleep, probably because it's been raining

or it's been cold up here.

Oh, my gosh, so cute.

We've marked some of these animals with a small chip and we're just

looking to see if this one's got one in.

I don't think it has.

We're just putting him in a small bag to weigh him.

There's plenty of air in there for the time this

dormouse will be in there.

19.5.

So why are dormice on the decline?

Simply because we don't manage our woodlands very well.

We used to cut our woodlands regularly to take timber out and

firewood out and we don't do that any more.

So a lot of woodland is becoming shaded.

We used to cut out woodlands regularly to keep wood out

and we don't do that any more.

So the areas where dormice live, the shrub storey, is not

so frequently found in our woodland any more.

So now he's back inside that box and we block the hole again

so he can't escape.

And what we do is we take this box and we put it

back on the tree where we found it,

and now we know he's back safely in his box,

where he'll probably stay for the rest of the day.

Check out these very rare pictures of tigers

in Bhutan in South Asia.

The big cats were spotted on remote cameras gathered

during a three-month expedition.

The trip by researchers was done to highlight the need for greater

protection of wildlife corridors - safe places where tigers

can roam between different areas.

That's all from me.

Newsround's back just before 12. Bye.
