Transcripts For DW Birds 20240702

Buds, some of the most well loved creatures on us. But as humans cause the planet to change as an increasingly rapid speed, bugs being forced to adopt them to cope with great new threats than ever before. Such as changing habits, motion, climates, and dangerous new name. The badge buffalo for the survival, scientists are on covering the different ways in which they are adapting the we discover in the search even more incredible than we ever since most of the, the the, this is hell go live. The smooth archipelago of to nordstrom and coast, its gained a reputation to being one of the most spectacular places to witness but migration a so many but to use it as a stop as a site to refill on that drums. Its also home to one of the oldest, one of the large groups of the prison, the work talk to your can deer sca works with the institute for avi and research and will help him. So hes part of a team the starting the bud populations here. The longer this is, the land has a very long history of keeping on with a logical record. Im can smile on it again with a painter who move to have a good land in the 1840s, fell in love and then spend most of his life here thing im leaving, you began keeping methodical records of the burger and lockers and also published them in the book until fair. Thats why we know so much about local bird life in the 19th Century Division that weve of easy for with a few and not getting the problem. But the real scientific records began in the 19 sixtys. When the data became the standardized recordings were taken 7 times a day every day. And that tradition has continued to the present. Yeah, we have the world, all this Data Collection with standardized catches and can draw conclusions from that. We know how populations have evolved and above all, how migratory periods have developed in the wake of climate change, the theme of under the yoke and his colleagues use whats known as hell. Good trumps shepherd ing budge. The blonde says into a fund says that they can be called safely. The once they have been collected, information about them is recording, such as body weight of the wind. Blowing on the feathers reveals the buds from the muscle composition a good indicator of general health. They know exactly which spaces have been caused and home, and neither of this information can then be confed to Historical Records understand changes over time. The successors theyve noticed the Long Distance migrants are in trouble and the facing steep declines. The exact reason for this is on the road, but it still to be because of global habitats, destruction and lots of insects. Ready unimportant appraisals for many bucks for the loss of migrants. Isnt there any fighting you all can and his team have also discovered that black cops a migrating more than 3 weeks earlier than they did 60 years ago. These small warblers typically migrate sauce to the southern mediterranean and africa during winter to reach a warmer climate with more resources. Doctor Joseph Williams is studying the navigation here on how good on recent tracking data shows, not only to black cops migrate totally, but the direction of the migration has also changed the reasons. But its mike, right, is because they want to get to a place with a more clements climate. But recently, and, but recently, i mean within half a century is now really and boats are starting to migrate north, specifically to the united kingdom. Previously those who migrated north would perish in the cooler conditions, but no many who choose this route. So the only thing has been question was that this is in response to the fact that its just not as cold in the north as it used to be. And also the impressed, and people really like feeding the birds. And so actually like cods, have started to use both feet is comes, but if it is in the winter, and this is in the thoughts, feelings to why they are so successful on in going and you know, in some instances precisely the wrong direction. Its not just black cops who seem to have successfully adapted to roaming, punish the arrow and helga land. There was a 7 c, but this was also great. Please beneficial if i started without the fan and 1st began breeding on how of good land in 1991 and their numbers have increased steadily, sense was tired of the growth. So the idea that and not even offering numbers kind of count for any stack income, the tsunami, and some growth could be explained by other than its being attracted to the colonies. But the species is also extending its range generally, which means its doing quite well in the Current Conditions in the north and see if we can get pride in getting an update, clark, the safe, such as hiring and micro some of the governance favor to praise bases and to being pushed further and further, notice that this woman see temperatures. So perhaps this is helpful is janet population again is phenomenal ability to dive. Also allows them to access a greater variety of fish, some of the c bucks, but not every but im so easily adapt to the challenges of climate change. Meaning that somebody in contrast, again it can, he wakes in foam or as have declined. Charlotte and one reason might be because they search for food on the surface and having difficulty accessing fish from on the open. But we also observed during the particularly hot summer of 2018, that adults kitty wake simply a band and their nests and the rags. I thought it was really hot on the glitter, temperatures climbed as high as 52 degrees celsius documentation. That was clearly too hot for 50 adult birds were still in the area, but theyve left of their nests and buffalo. The awfully. The casey wait, such as ones pieces of thousands across the world. Theres a decreasing a number, the one for things, most iconic spaces. The sky now is famous for its rich and intricate. So the smooth grounds, nesting but often chooses to raise tricks on grossman and farm. Historically, the lack of your so called some groceries has allowed them to access the grounds to nest and to keep an eye out for predators. With the intensification of agriculture is habitat is becoming a dangerous one. The wide spread change from spring to awesome sun cereals has increased the density of crow pushing sky locks to nest near tractor tram lines, making them vulnerable to crumpling to predators as pesticides. And wed colors are sprayed more and more on crops, insects. An important part of the food source are also being diminished. And so in europe, nearly 70000000 individuals have been lost since 1918. And the numbers still continue to full. The professor amanda room and her colleagues at the corner elaborate bonus ology in north america. As im covered, an even more devastating tab decline in north america. We have lost 3000000000 periods from the reading population of nearly 30 percent of birds or one in 3, or is that have been lost to just in my lifetime allowed. So since 1970, were seeing these declines that are really spanning almost all habitat and almost all groups of species and no longer restricted to just to be safe that we might of know already been thinking of as requiring conservation attention. Instead, were now seeing some of our greatest declines in species that are funding that are common in wide spread. The declines that weve documented here in north america are in no way unique. There have been studies that have been coming out around the world that are documenting. Youre comfortable. Declines. So its, it really was a wake up call. I think for a lot of the Conservation Community here, but its provide a lot of whats known as ecosystem services. They disperse seems all in a cons. Keep insect population such as birds decline, so to well, these vital services. If an environment conditions are not sufficient, not healthy enough to support birds. Well, then theyre not likely to be good for people either. Its a birds can be a real sentinel of environmental change. Weve heard of like canaries in the coal mine, and thats not so far fetched, right when we c declines and birds that should alert us so that somethings happening in the environment that we should Pay Attention to. Because ultimately, it can come back and affect us as well, the 3rd being the subject to decline for a variety of reasons, such as habitat destruction, fragmentation, pollution, global warming, the meanwhile, human populations around the globe of weeks and full time high h value to sustain this growing population, agriculture is becoming increasingly intensive. Some birds have adapted to thrive in these conditions. Grazing on managed gross acropolis learning to utilize the source of high quality food as a loud budge, such as conical goose to increase dramatically in europe. But as we continue to add the noise, the punish, were seeing new and unusual problems and much for all bucks to mitigate natural noise such as wind birds can change the page volume or time at which they sing, which in areas of high human population thurman, not from noises which are not so easily overcome the Max Planck Institute for one apology in germany is one of the largest senses, but science in the world. But the full front of Cars Research is dont to henrich broke. He began studying the effects of such sounds on budge, over 20 years ago. Thats on the t of out when the birds have to compete with noise, they sing louder. So have you met . You must do that too. We authorize our voices. I can go to this, this guy so long through great birds. And so just say enough, for example, nightgowns and berlin altogether they sing louder when theres more traffic noise. That means that the animals sing more quietly, the weekend and cheering the week until they have a nice ready for thats not because the birds relax and take it easy because of weekends. There is less commuter traffic and therefore less noise. Because fuck you, as a result, the birds sing more quietly. Ultimately we are the ones producing all the noise and compose the birds to sing louder and louder and sing and my, the all types of thing. So as mentioned is level vision for the for as humans, noise is a huge problem in our best, but its become increasingly clear. The noise has similar effects and birds for those. For example, a city traffic causes chronic stress and birds, which in turn suppresses their immune systems of dealing with. Thats what the nice thing is our latest findings on which we recently published it to show the traffic noise can cause birds to have trouble learning, to sing just to put further pulled niema because of just as human children learn to speak because he mentioned the birds have to learn to sing the traffic noise has the effect that it is taking them longer to develop their song. And they also make more mistakes when learning. I think the scene of the song quality is inferior and sound funny to have to finish the thing because i, im just going to say 1st id like to see and so i can implement this overall fitness. So potentially lead to a change in a populations dynamic. Right . Doesnt guns to got poor. And thats an important point. Especially for species that are threatening to do that to you, of course. Because along with all the other issues, animals face to, to human and choose to environmental change, such as the Climate Crisis solution, etc. Theres also noise and that noise could be the final straw to try some space, use to extinction. Going around, i need to often some of them but its not just the noise. Light is also wreaking havoc on birds around the world. The reason male songbirds stop singing in the winter is because the go nach frank, this is a result of the day like like not true sure thing and went with the last day life. They can no longer produce the whole much to modify the brands and therefore allow them to sing to bring but street lights and tom some cities need. So this natural life cycle resulting and but coming to breeding condition, much sooner than they would otherwise not truly do meaning the off spring. Lisa nest when there was level for them yet to each Light Pollution from buildings is also appropriate to some unknown reason. But its a drawing to the source of light causing life threatening conditions. Cornell and museum of flesh birds in north america, votes of foss, collection of birds, many of which were found just fatalities from hitching buildings. Dr. Benjamin vandorn and his colleagues studying these books. So lot of these birds come to us because they have collided with windows or buildings. So one of these pieces is a block sort of blue or blur here, which is a song bird migrant. This is the fate for pending and so, but its across not only north america, but the well with the use of new technology from the kona lab as on the solar gee in new york state. There is hope that we can make a difference to adrian. Dr. Is part of this team, migratory versus a tranquil ignites and, and its actually in ways of a hidden phenomenon. If there is costs, we try to sort of make these market towards your initials. Birds come to life and use mostly raiders for that. These a whether re dos or a 155 dose it across the us site and mostly used for detecting rain. But the scientists here at cornell, the found a way to use them for detecting but the weather writers. They cant really see individual graphs as maybe like rain clouds, right, where you also dont see the individual droplets. What you see. So if this density of mass of rain from the air is the same reverse. Although its not possible to see which exact spaces are on the move. If we bird migration across the usa can be tracked and displayed on a map. So you see all the green dots on your radar stations. And in colors in the back, youll see the migratory birds and, and youll see the brighter colors. That means more bars in the year. The red line, the policies across the screen represents the point with which day becomes nice. As soon as thats sort of gets dark, you see all these bright super bright colors popping up. So really good migration. Nice. We track also how many, but migratory birds are in flight if theres any given moment. So you see a staggering numbers. Were now is 830400 1000000 birds in there. You see now the sun rise and you see as soon as some sort of starts to appear or landing. I think this too is especially good though to see these evils are very large scale patterns across to us. Something we can never do before. Theres like millions and billions of books in the air and it hasnt just been impossible to count that. It seems like in the middle of the night, so you can see if its only since we know how to use the rate or network, lets see if this would inverts. If you overt migration itself, you can zoom out to the scale of an entire confidence and see what the migration looks like. And how is this the view to the space both Cost Technology to most of the truck migrations. It can predict them to as weather radars have been around for decades, the archive can Migration Data from the last 20 years can be collected and compared to the weather conditions, but were experiencing by combining those 2 sources of information. We can create a predictive model that will tell us how much migration we expect to, to take place under a given set of conditions in a given area. And really convert a Weather Forecast into a bird migration forecast to benjamins on door and uses this information to protect, but its against the dangers of Light Pollution. So if our migration forecast sites, for example, that we expect millions of birds to be migrating over, dallas, texas. And we will then put out in advisory that day to, to say, hey, we expect lots of migration tonight. Make sure to turn out your, your lights tonight, and so our network of people will work to make that happen. Then that night hopefully theyll be the fewer lights on, in that city. Turning out lights makes a difference even at the level of the individual window in the building. And through our work, we were able to show at, at one Convention Center in chicago, that if this building has participated in a Lifestyle Program and turned off se half of its lights on a given night for a long period of that bird mortality at that one building could have been reduced by 50 percent or more. And over the course of 20 years were talking about 5000. 00 or more versa. And that could have been said. There are many challenges in the world that are really complex, like light climate change, but light Light Pollution and the impacts of light on birds. This is a problem that people can make a difference. Its really something people can do with just a flick of, of a light switch, migratory birds. Some of those that are being hit hardest by changing planet. But some books pieces are adapting to the new environments created by humans. Adults bugs introduce the young to these opportunities so they to grow up to be told her aunts of people with disabilities as it allows them to not only live along side humans, but to take advantage of the one of the most as an adaptation to a man made world is the gulf the they see flat troops of city buildings as perfect nesting platforms at a safe place to raise the checks tables a land to follow peoples should use beating when the most food is available. If, if that means for jane at night, pale next thinking up in areas, im much higher rates anywhere in the past. Same one, locals. Amazing in the app in areas. Sir, it seems like something is going right for them. Still to model in goodness from the university of extra to is starting tearing goals on the south coast of england. Ive noticed just like very clear when im out in town, but people have the fee taken by goals and it often went to not paying attention and goals will just catch them unaware, often flying in from hines or even a show the and i wanted to so actually paying attention to where people are looking. Im now using this to as, as a way to decide how to get this feet, sorry, designs and experiments to explicitly test the model in places a bag of chips on the ground and trips a way to see how long it takes until the snatched the within and leave 15 seconds, theyve gone the now for the next test, i want to go react when modeling maintains her gaze off to placing the troops down. She waits the but this time, the goal doesnt take the risk. Those who are brave enough to steal food whilst being watched, often take a significantly longer time to make this decision compared to those that think that going unnoticed. They wait, typically over twice as long as someones not looking. Then its going to be much easier for them to get the series and get to wait for the pass and is able to react. Because obviously a human is a lot bigger than a goal. And as a lot more thing to circle open by fast so, so it really would pay off for both to be paying attention to where people are looking and see approach fees when people on but somebody can take this ability to exploit foraging opportunities. One step further, one of the worlds most intelligent spaces about this here at the tower of london. Chris gave is a human award, a position which requires at least 22 years of military service. Hes responsible for looking off to these regal creatures. Good morning to gaining the title of raven, most of the ravens have been here since at least the reign of king charles the 2nd in the 1600s without the ravens. So the legend goes, the town will crumble into dust and grey tom will before the kingdom. And so that protection is the central, the ravens of the largest spaces of calls. It was the wingspan to fill most 5 feet under much larger brains than most of the boats. And the wild seas inquisitive creatures unsuccessfully as in a wide range of habitats. Thanks to the gentlest start, using pretty much everything they can find the because of the great celebrity here that visited by millions of tourists each you know that states and the ravens know just how to use this to their advantage. Im always taken back by what they do and how they observe humans. Theyre watching is all the time they lost the food. Thats what they were often that planning the day around what they can scavenging and very often with what they can steal, of course, as well. They Work Together. I can see them planning tactically, hows it going to do this . And they use the crest as a bang and hide behind was a one of them, the district and on the suspect can visitors. And so they was ready to start then a spike in pick this time it dropped a bicycle for the last i can watch that the but its actually planning on salt and im talking to each other about how theyre going to do it. The ravens are intelligent enough to Work Together for food, or say no, this collaboration will lead to a meal. They can both shot but some birds are capable of team work, even if it doesnt lead to an immediate reward. To august phone buying from the Max Planck Institute. Wonderful. The truth is starting in temperatures and co operation in powers hair. Its laura park antenna was there are around 350. 00 known spaces apart, most of which live in complex sophie flux. Although the brains are roughly around the size of a wall notch, pirates power, no gray types and dolphins in the cognitive performance. And so they can be trained to carry out, come on well ghost and her team have told african great parts to Exchange Tokens for food. But once the 6th strain show becomes blocked, how do they react . Test subjects, receipts or the pulses f 15. 00 experiments up, but without any opportunity folks change, it just gets the tokens and no food thats its the next solid is neva and its 10 exchange and a paid for that. At the same time, its next sofas. The pirate with the tokens doesnt want them to go to waste. So it pauses the tokens to which neighbor, at least they can benefit from the food. So we found that right parents have the individual is to achieve or goal without immediate benefit to them says. And even was also an opportunity for us implication. And this is really a successful of finding because such this, this f m has only been shown in great h species in, in comparable studies. So in our closest relatives, and our finding is really the 1st reports of a 1st, the coping in and im not in the median species. An explanation for altruism with a pump now is that the 2 parents become stronger as a unit. So they can better take care of that checks. But for some reason, parents will think so help those who and ne pump is helping others to achieve a goal like this is very complex. As the individual must recognize when health is needed. And when those exchange holes blocked, the pirates with the tokens can understand, so the neighbor wont benefit from them. And so just trying to help the really whole set of findings, we make it very clear that we have completed the estimates. Its in intelligence. And thats the so if we got them a said that a so to say, because they have amazing abilities that intelligence isnt always the key to survival when a rapidly changing planet or sometimes district is to be adaptable. And once pieces of part is used, its adaptability to firmly establish itself as a new resident in new york. The roads ring in ring necked parakeet for the growing population of parakeets is also having an unexpected impact on londons population of power going focus edge druids is a paragraph research, and hes come to this church in south london where a full paragraph and checks to just fledged often nesting on the spot, but almost at the base of the tent spot now, where we can then go out and look for some pre remains. To know the breeding season is over and can look at the remains of that prey to work on what theyve been eating. Ah, see what weve got down here in test take. Pair of goods are being, feel no different stuff down here as lots and lots of white and gray, thorough pigeon feathers, pigeons. So usually the power returns go to pray that one new come a is appearing more and more in the dodge. The adults a catching power keeps. Im bringing them back to feed. The grow intrigues it just hold on for heat all day in the power going dodge the large orange beaks, a shop and in the adjustable. And so were left as evidence for it to answer this very question. So what im doing here just looking for these. Thanks to go out so you can see the bright, green feathers, the par teach. You know, when you see a place you can see, see how old is luminous green it is in this bright red. Its not known exactly how these pirates originating from asia and sub saharan africa, made some way to london. But one theory is that they would kept as pets in the cities, some managed to escape, and they successfully bred are now estimated to be around 8600 breeding past living in the u. K. Pair, were going to have a very wide don. Theyll take whatever is an abundance a by these parents which uh, originally started reading in the u. K. In 1969 and actually between 19952000, that population increased by almost 2000 percent because of so many of them in grades. So im done with finding that reading that power keeps of perhaps taking a 2nd off the place in the most eat some prior. During the breathing season, in the late 19 fifties, the population of power group focused, crushed due to widespread use of the pesticide d. D. T toxic chemical with sprayed on crops, poisoning the prey and working its way up the food chain into the parent rooms themselves. This caused them to lay eggs with shelves to put to sit for a clean number of the way so the incubating nato. Once this link was known, d d t was finally bind in the u. K. In the 19 ages, paragraphs of sense made a startling recovery, reaching almost 1700 pads across person. More than double the population before d d t. As a result, that traditional coastal habitats have become saturated. So many have adapted towards urban environments can offer instead, the, all of these old bits of power and into his line is up now is quite as going to be quite a few here. Right. So im ready to count. Now lets see how many weve got. Okay, so lets go through 123456 of the 7 to the 8th and the 940 for 1. 88. Its 9. 19919191. So a little bit less than last year, but actually that is still a huge number one. So i thought i had this sheet ill be watching on the webcam or 237. 00. And also that was the last minute power keeps on becoming the force of paul, the power we can talk. I bring that power seats continue to grady i out in all the parts of england. And i think everyones already that im probably going to be doing even better than i already off those type of goods or the feeding on federal pigeons and stallings. But as if you then asked to bring that power seat into the mix as a spaces the is, is all around the place, relatively easy to catch. The not sure thats probably gonna increase the breathing success phase periods, the, the power keys and prepare goods ability to adapt to a changing world is a hopeful sign that others may be able to do the say the which the birds to do this. They must be able to learn from new experiences. It still does in humans and other mammals. A vital part of learning is the foundation of memories. When dreaming. The, the dr. Joo nina ongoing from the Max Planck Institute for lona solar j studies if but like us re experience daily events during rims, the stage in which we might creek the, the budapest pigeon. As transparent pilots instead of the movements of its pupils can be recorded when its uh, is it close to a to study this at night g, anita must observe it on infrared light, which the book cannot detect the officer switching on the infrared camera. She enters the avery to put the pigeon to bed on its got the where were seeing here is uh, sleeping pigeon. The pigeon is initially a non room sleep. Its eyes are closed and is a briefing regularly and its quite quiet. And then it enters into rooms sleep, so the ice starts moving around and you see the pupils constricting rapidly. So our study, we found out that these people very constrictions were specifically linked to this particular slip state through random sleep. We also showed for the 1st time that the pupils of pigeons are constricting during a courtroom during wakefulness. So because these people are restrictions occur during the day in seemingly during the emotional states and the rear occurred during rend sleep. We think that the people are restrictions might reflect times when the brain is reactivate. A Brain Networks that havent been activated during these emotional states and the brain is replaying and processing these information. The we still dont fully understand the new or logical functions of dreaming. All shows that studies seem to suggest that other animals use dreams to cement experiences from the day in the memory, and that from the, from the birds in are rapidly changing. Anthropogenic world. Civility to learn is up to 5 scale. The there are many ways in which buds are responding to a changing planet. Some gave me the opportunity to thrive in new habitats by accessing more nutritional food and resources. Such for many others hunter, projecting change is having the devastating impact or anything, habits on populations around the world whilst intelligent and deductible, but learning to survive and unexpected conditions. There are millions of uh, tools perish with us. All health as we know more about surge and how to protect them. Thats how the future generations will continue to live alongside these magnificent creatures. The feed in good shape, are you never hungry, lethargic, and constantly tired or nervous attempts, man, always stressed out. These big problems can have a very small cause. The thyroid gland.
