0:00:03 > 0:00:05Hey, eveyone, Leah here with your Saturday Newsround.
0:00:05 > 0:00:08Keep watching because...
0:00:08 > 0:00:13It's Strictly Saturday and Ore's hot....
0:00:13 > 0:00:15but Brendan's not.
0:00:15 > 0:00:18And the three heroes helping hedgehogs.
0:00:18 > 0:00:21And scientists use a drone to spot a rare bowhead whale.
0:00:31 > 0:00:34First up, we're already getting excited for week five
0:00:34 > 0:00:36of Strictly Come Dancing tonight, but professional dancer Brendan Cole
0:00:36 > 0:00:40won't be taking part.
0:00:40 > 0:00:43He's missed training all week as he's been ill.
0:00:43 > 0:00:46His celebrity partner Anastasia has been practising with Tameka's
0:00:46 > 0:00:48ex-professional, Gorka.
0:00:48 > 0:00:52And now he'll step in on the live show, too.
0:00:52 > 0:00:54Now, not that we have any favourites on this show,
0:00:54 > 0:00:56but last week's big star was ex-Newsround presenter
0:00:56 > 0:00:59Ore Oduba, who has surprised us all with his moves.
0:00:59 > 0:01:05Ore's busy with practice but he managed to send us this.
0:01:05 > 0:01:08Hi, Newsround, it's Ore, and... Hi!
0:01:08 > 0:01:13You might recognise this gal from Saturday night.
0:01:13 > 0:01:15We are in rehearsal day.
0:01:15 > 0:01:18Believe it or not, there is a lot of work that
0:01:18 > 0:01:20goes into this show, of course, but you need to
0:01:20 > 0:01:22also rehearse... Where to stand.
0:01:22 > 0:01:23..standing.
0:01:23 > 0:01:25And walking downstairs, so these stairs behind us, we have
0:01:25 > 0:01:27to practice walking down them.
0:01:27 > 0:01:32Jo and I are dancing the waltz this week, which is very different
0:01:32 > 0:01:35to what we did last week, the jive, and to get...
0:01:35 > 0:01:37What did we get last week, Jo?
0:01:37 > 0:01:3839.
0:01:38 > 0:01:39We got 39.
0:01:39 > 0:01:42We got 39!
0:01:42 > 0:01:45Biggest score in week four in the history of Strictly.
0:01:45 > 0:01:47Wow!
0:01:47 > 0:01:49Shh - don't tell anyone!
0:01:49 > 0:01:50Erm...which is amazing.
0:01:50 > 0:01:53We had the best time last week, and hopefully we'll have
0:01:53 > 0:01:57another great week.
0:01:57 > 0:01:59But thank you for all your support.
0:01:59 > 0:02:00We will see you Saturday night, BBC One.
0:02:00 > 0:02:02Hopefully we'll be back for another week.
0:02:02 > 0:02:09Bye!
0:02:09 > 0:02:12It's been a topsy turvy day three in England's third test
0:02:12 > 0:02:13against Sri Lanka in Bangladesh.
0:02:13 > 0:02:15After taking four wickets for 21 runs this morning,
0:02:15 > 0:02:18England looked to be in a very strong position, but Sri Lanka
0:02:18 > 0:02:24hit back taking five wickets in 27 overs.
0:02:24 > 0:02:27England have now steadied the ship somewhat and have a lead of 258 runs
0:02:27 > 0:02:31with the score currently at 213-7.
0:02:31 > 0:02:33In football, Tottenham have a chance this lunchtime,
0:02:33 > 0:02:34to go top of the league.
0:02:34 > 0:02:36For a few hours at least.
0:02:36 > 0:02:39They travel to the Vitality Stadium to play Bournemouth and kick off
0:02:39 > 0:02:41is in about half an hour.
0:02:41 > 0:02:45Here's the Spurs manager, Mauricio Pochettino.
0:02:45 > 0:02:49It is a good opportunity to see us on the top of the table.
0:02:49 > 0:02:52But first of all, we need to win the game.
0:02:52 > 0:02:58And in front we have a very good team, a great manager
0:02:58 > 0:03:00like Eddie Howe, and it
0:03:00 > 0:03:05will be a very tough game.
0:03:05 > 0:03:08Now, when was the last time you saw a hedgehog?
0:03:08 > 0:03:09Last week?
0:03:09 > 0:03:10Last month?
0:03:10 > 0:03:11Ever?
0:03:11 > 0:03:13Well, research carried out by the Suffolk Wildlife Trust has
0:03:13 > 0:03:16found there has been a huge drop in the number
0:03:16 > 0:03:17of hedgehogs in the UK.
0:03:17 > 0:03:20Martin has been investigating.
0:03:20 > 0:03:21Hedgehogs.
0:03:21 > 0:03:24They're cute and prickly, but life in busy towns and cities
0:03:24 > 0:03:29can present some real dangers for our spiky friends.
0:03:29 > 0:03:31So what being done to help them?
0:03:31 > 0:03:34Sanctuaries like this one just go to show the problems these little
0:03:34 > 0:03:38guys face in the big wide world.
0:03:38 > 0:03:41Anne has about 80 to 90 hedgehogs here, all tucked up safe and warm.
0:03:41 > 0:03:46They come from various sources.
0:03:46 > 0:03:48Usually found by people who bring them to us.
0:03:48 > 0:03:49We have abandoned babies.
0:03:49 > 0:03:59Babies that have wandered off and got lost.
0:03:59 > 0:04:01Injuries through netting, strimmers, and road accidents.
0:04:01 > 0:04:04We also have sick ones that are found lying in people's
0:04:04 > 0:04:05gardens, obviously unwell.
0:04:05 > 0:04:08We try and get them up to weight as soon as possible.
0:04:08 > 0:04:09And then we release them.
0:04:09 > 0:04:1125-year-old Ali is the youngest hedgehog officer in the UK,
0:04:11 > 0:04:14and it's her job to link up these areas of green space,
0:04:14 > 0:04:17to give hedgehogs the chance to move around freely and safely
0:04:17 > 0:04:20when the come out at night to feed.
0:04:20 > 0:04:24We've obviously got lots of great parks across the town.
0:04:24 > 0:04:29But also lots of houses and walls, making it difficult for them to get
0:04:29 > 0:04:32between these great habitats.
0:04:32 > 0:04:39We are trying to get volunteers on board who will manage
0:04:39 > 0:04:41their gardens for the hedgehogs, and will hopefully persuade
0:04:41 > 0:04:42their neighbours to do the same.
0:04:42 > 0:04:45So we have these whole streets of connected gardens
0:04:45 > 0:04:48that the hedgehogs will be able to easily navigate their way through.
0:04:48 > 0:04:50We've got a hole down here so they can get
0:04:50 > 0:04:52through to the other gardens.
0:04:52 > 0:04:59Ten-year-old Daisy is one of the many people from across
0:04:59 > 0:05:01the UK are doing their bit to help the hedgehogs.
0:05:01 > 0:05:04It's important to take care of hedgehogs because they are
0:05:04 > 0:05:06endangered and I want them to be around when I'm older.
0:05:06 > 0:05:11I've been making it somewhere that's the hedgehogs can come and live in,
0:05:11 > 0:05:20stay and get some food and .
0:05:20 > 0:05:26-- and hibernate.
0:05:26 > 0:05:28I've made some houses, and I give them water and give
0:05:28 > 0:05:29them food and mealworms.
0:05:29 > 0:05:33Anyone my age that wants to do it, I'd say, yes, they can do it
0:05:33 > 0:05:36because the more help that we have, the more hedgehogs there will be.
0:05:36 > 0:05:38And finally, scientists in Canada say they've capture rare footage
0:05:38 > 0:05:41of a bowhead whale - one of of the country's
0:05:41 > 0:05:42largest marine mammals.
0:05:42 > 0:05:46They used HD drone technology to help get researchers
0:05:46 > 0:05:49closer to the creatures to understand their food and travel
0:05:49 > 0:05:53habits in the Arctic Circle where they're found.
0:05:53 > 0:05:55That's all from me.
0:05:55 > 0:05:58Newsround's back right here in at 1.40.
