Today I'm with ZSL, the Zoological Society of London, as they carry out their annual census of seals on the Thames.

Now unfortunately the best way to do that is by using one of these.

Hello, Theo.

- Hi, Andy.

Hi there.

Come on in.

Thank you, sir.

See, I see a map of the Thames estuary here.

Is that where we're going to go today?

Yeah, so Andy's going to take us up over the Thames, over the sand banks and the coastline, and we're going to check out how many seals we can see.

Now Andy, I understand you've been flying this part of the world for 20 years.

And in that 20 years, you've seen the seals the whole time?

Yeah, I have.

I think it came as a surprise to everybody that there were so many in the estuary.

But of course you live around here, do you think most of the population know about the seals on their doorstep?

Most people do not know there's any seals out there at all.

And of course the $64 ,000 question, will we see some today?

Previously when doing these kinds of surveys we've seen good numbers and we're doing this survey at the right time of year.

So fingers crossed, we'll see plenty today.

Let's go spot some seals.

We head out to Margate Sands looking for grey and harbour seals.

I must not go to sand over there, so it's whatever the one is next to it.

It's not long before we spot our first group of seals.

I think I can see some seals on the end of this picture anyway.

Right on that bend there, there's maybe about ten seals.

Wonderful.

Real variation in colour as well.

Thea takes pictures of the seals to analyse later.

And I'm using a GPS unit to help identify where each group is found.

- What's your weight point?

- Weight point 224.

I counted 19 seals there.

They all look like harbour seals.

This is cutting edge conservation work on seals and it doesn't really get much more exciting than this.

The seals are coming up again.

- It's well there, some pups, beer.

Back on the ground and Thea is already analysing the results.

After each survey, we take all the photos and we go through them all, identify the species for each bank or point on the coastline.

And we come together to ensure that if there's any discrepancy between number or species ID, then we work that out together and make sure that we've got as close to an accurate count.

as we possibly can.

What more can you tell from just that picture alone?

We look at each individual seal and we look for features that indicate what the species is.

So for a harbour seal, For example, Generally you'd see the eyes on the front of the head and a shorter snout,

whereas for a grey seal you'd see usually like they call it a Roman nose, so it's sloping, the eyes further back and to the side.

And that's a harborsie, a much more dog -like with funny little nostrils and angle as well.

Since ZSL began monitoring the sales six years ago, numbers have doubled.

with an estimated 3 ,500 of them living in the Thames.

We take the increase in seals that we're seeing as a positive sign of the health of the ecosystem.

We should be very proud of the Thames, it's incredibly biodiverse, it is full of life.

It's not just brown, underneath there is plenty of fish and all sorts of other exciting species.

What's particularly exciting is the harbour seals are actually breeding in the Thames estuary.

first ever pup count.

We recorded 138 pups which is great news.

There was a survey back in 2011 by the Sea Mammal Research Unit

and they recorded in the region of 40 pups So that does suggest an increase.

It's strong evidence that obviously the Thames is a breeding site for these animals.

The river has come a long way from 60 years ago, when it was declared biologically dead.

London and the Thames at Wandsworth illustrates a quaint facet of the river pollution.

It seems a nationwide demand for clean rivers is the only hope.

We're much more careful about what goes into our river, so Sewage treatment works as an example of that.

And we really have come a long way.

That's why we see all this life, but that's not to say we don't still have some way to go.

to keep maintaining this trajectory of a healthier Thames.

Pfff.

The cleaner water is providing fish for the seals, which are now being spotted across the capital.

How far are we seeing seals moving up the towns?

- So we're seeing them go all the way up until the tidal limit in Teddington.

So they're traveling all through central London

and there are kind of hotspots around London where people see them

and they are generally where you get a higher footfall or you have taller buildings.

So Canary Wharf is known for a bit of a hot spot for spotting seals.

And people having interactions with them as well.

Yeah, there are some interesting videos that have popped up of them climbing aboard the front of a kayak or a canoe.

We don't know necessarily where this behavior comes from, but they're curious and inquisitive and highly intelligent animals.

But it's not just seals that are turning up in the Thames.

There have been recent reports I've harbored porpoise.

Dolphins and even seahorses as well.

But perhaps most astonishingly, in 2018, Benny turned up.

The first ever beluga whale in British waters was found just down there.

Amen.

Oh The whale, nicknamed Benny the Beluga, living in a stretch of the Thames, may be able to survive there, according to experts.

Our very own wildlife cameraman Russell Savory was lucky enough to capture these shots of the beluga.

Cruise ships, the bulk carriers and things were going up and down the Thames and this beluga just bobbing around there.

Obviously fishing I guess but to be able to get a beluga in the Thames, it's just unreal.

while undoubtedly the best way to sense the seals is from the air.

If you want to get up close and personal, you're going to need another form of transport.

I want a boat.

We never used to see them, but over the last ten years they've started off from about six seals, and now they've just gradually got more and more seals around the coast.

Where we go, six seals are now 120.

Stuart Barnes runs sail tours on his boat along the Thames estuary.

Hopefully I can get you in the region of about 10 to 15 metres.

Yeah, let's go do it.

Ten minutes from Grumsgate Harbor and a magical sight awaits us.

These are all harbour sales, getting the most wonderful views.

The thing that I'm amazed by is the colour variation.

Some are black, some are grey, some are blonde, some are ginger, some are variegated and spotted all over.

And there's a few youngsters that were obviously born maybe five, six, seven weeks ago, just on the water's edge.

It just goes to show the Greater Thames Estuary is in pretty good mig.

We won't know the results from this year's SEAL survey for a few months.

But from what we've seen, the population here is thriving.

And so, is the Mother Thames.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
