Why animals migrate - part 1 of a two-part CrowdScience investigation.
Wherever you are in the world, you are probably near an animal that has undertaken a remarkable migratory journey, be that a butterfly, bird or sea turtle. But what CrowdScience listener Moses in Kenya wants to know is, why they bother making such long and precarious voyages - and how they're able to reliably navigate over hundreds and sometimes even thousands of miles. In this first of two episodes, presenter Anand Jagatia travels to the Americas to meet the scientists finding and tracking these animals in order to solve the puzzle of where they go and why.
Deep in the lush and noisy Belizean jungle, Anand joins avian biologist Abidas who is collecting data on the beautiful birds that visit tropical forests to escape harsh winters. Here, using misting nets, Abidas and her team carefully catch birds to measure their health and status before tagging and releasing them so they can continue stocking up on jungle food. Anand finds out why having long term data on migrant birds can help in understanding why some birds, like the wood thrush, have been declining in their native homes further north.
Anand then jumps aboard a turtle boat in Florida where scientists from the Sea Turtle Conservancy have been collecting data on these dinosaur-like creatures. But finding them is harder it might seem. They move fast, so Anand accompanies the research team who are experienced in safely catching them, will he be lucky and find one of these magnificent creatures?

I have watched this scientific video with full attention. I think people who are investigating the birds migration like the nature. We have to appreciate their efforts.
that´s a great deal of interesting information and creates more questions rather than answers
Many interesting and unique information about the migration of birds. Thanks for your hard work and making this publicly known for us to discover
Birds have their own sat-nav, bravo:)
Omg, this subject was my first storybook learning for English. 😊
Great program .. The hard work by your team is appreciated... Presenter made the program very interesting
This's nice one for me to practise my litening skill✌
a good piece of information.
Part-2? When will it be released?
Great program :)

I will listen to this in bed at bedtime. Perfect for bedtime entertainment.
Same to you I also listen in bed at bedtime
Lots of great information here! Thank you!
You guys out there proving the proverb "THE EARLY BIRD CATCHES THE WORM" wrong. LOL.☺
Great video, thank you
Very good
I watched one documentary about birds, produced by BBC (I thinik), in 2000 or 2001, it was so wonderfully shot, it showed the birds visual perception, like how birds can see earth's magnetic field, the various colors, their bifocal ability, winds stars and how can they come back to same place after travelling 1000 of miles, if somebody knows about that documentary please let me know

Great 😊
Nice documentary.Showing less information by visuals.Add more visual effects so that viewers get holistic view of the process.
So nice😊😊
If there was such thing as reincarnation I would love to be a bird in the next one lol being able to travel the world see it from a birds eye view literally
Alhamdulillah barokah...aamiin
Amazing real story
No video((((😢
Where is the video
Birds: the original frequent flyers!
Why can't I see the video😃
Thinking about it!
Me too while hearing this out in a gym and wondering on how the bird looked after hearing his cute sound

More than anything I am not sure and again it is thanks to LORD, how in that script so much meaning got added.
Thanks to the Lord
Interesting
Thanks I am interested in Bird migration, seems once they take a route no matter what continue using the route even when no longer safe, Newark is full of Glass buildings. Newark is on the Atlantic Flyway. A Freind & I rescue birds that hit the glass skyscrapers in Newark NJ, Most birds that hit the skyscrapers perish on impact, or when fall to cement. TRT made a video 'Window Strikes in the Business District' of us picking up injured Warblers. TRT nurses them back to health. I suspect some birds can 'learn' to know Glass i there , as noticed pigeons & starlings & English Sparrows rarely hit, I have seen fledgling Starlings hit and expire ( 3 babies entire nest on same day) felt bad for parents.
Hello 👋
This a great video, I would like to express my appreciation for all of the people who made this video, thanks a lot!

Season.
So why is it woodpeckers and chickadees do not migrate from Canada south?
For food for safe residence for good climatic conditions

I heard that the house martins in Africa plan their return flights to the UK each summer starting with a general briefing session. All the birds get together and the chief bird reads out the winter temperatures for the Arctic and proclaims that as global warming is so bad they will put off their departure until a week on Friday.
How else could they do it? They can't rely on local African "weather" they need real climate data ideally averaged over the entire globe.
Are you trying to hypnotize us?
First send the invitation and offer to birds
All tech companies will agree too
People are sceptical because their nests are destroyed their offsprings are disturbed
Just for relaxing and geiiting a strong passport.
Cause they dont have jackets for winter...duh......
Give me some money. 🌹
My Allah is the remover of all hardships, fulfills everyone's needs and will continue to fulfill them, God willing
My god and your allah are great who cares all the world 😅
Ud chal haril fly away haril
If England proves that they are not in the contract of attacking love channels, they can find a cheap place that is not totally occupied like villages in good climate area for all tech companies to migrate
Because they are in danger by that contract
Give me some money. 🐦
Why u r looking for money towards others on the contrary you can earn money by your own effort.

Whats the advantage of doing this work to the nature???? Leave the birds on their own and do what ever they want to do....Dont we have better things to do???
😅😂

Human beings have copied how birds can fly to create airplanes. What makes birds' natural flying ability and human-invented flying machines distinctly different is that birds' natural flying does not cause any pollution or damage to the living conditions or environment on this planet, whereas human-invented flying machines do, which is one of living proofs which show that human knowledge is extremely limited
Muslim Qur'an pya Malaysia
Child 😂😂😂
Birds know food sources are going to be limited under snow or soil due to heavy weather conditions they can't survive from those natural challenges. So life is important to never take any risks about it. Also, did you stay under rain night - day at least 3 days continuously without eatingant drinking anything? Look at the life from bird's eyes. Die on the immigration way is better than waiting for die. This is Life itself.
👍👍
