It is with a heavy heart that I must report the loss of Баян (BAYAN), one of the Mongolian Cuckoos.
The last signals received from his tag were at 1035 local time on 12 May 2020 and showed him almost exactly 100km north of Kunming in China’s Yunnan Province. Since then, there has been radio silence. The following analysis of the data from BAYAN’s tag was provided by Dr Chris Hewson of the British Trust for Ornithology (BTO) who fitted the tag to BAYAN in Mongolia in June 2019:
“…there were some slightly unusually high temps around 1000 local time on 9/5 – reaching 40-41 C on the scale of the PTTs, compared to a normal max in the high c 35 C even in Africa (it does rise to around 37-38 C on occasion though). The tag temperature was also pretty cool the next morning, probably cooler than it should be – down to about 26 C, which is probably indicative of lack of regulation of tag temp due to behaviour / absence of body temp buffering of temp. My best guess, all things considered, is that Bayan died between 1000 8/5 and 1000 9/5. The circumstances of disappearance are similar to Flappy who died in Myanmar on spring migration. These birds are really racing on spring migration, which might leave them vulnerable to not finding good stopovers / predation etc.”
In the small hope that the tag’s temperature sensor was malfunctioning or there was an alternative explanation, we waited a few days for further signals. None were forthcoming, strongly suggesting that BAYAN had indeed died on 8 or 9 May 2020.
It is always sad when we lose a tracked bird but we should celebrate his life and the impact he has had on people around the world.
After crossing the Arabian Sea to India, hot on the heels of ONON, he captivated a country with an incredible surge of interest among people in India, most of whom were previously unaware of the distances travelled by some of the most familiar migratory birds. Below are just a few of the reactions to BAYAN’s crossing of the Arabian Sea:
BAYAN is almost going in same path as ONON, we are waiting to welcome BAYAN in India🇮🇳
One of the main purposes of the project was to reach and inspire more people about the wonders of bird migration. Judging from the reaction on social media, BAYAN certainly did that.
Being able to follow the incredible journeys of these cuckoos opens our eyes to the phenomenal endurance of these birds and the mind-boggling distances they travel. It also reminds us that migratory birds live life on the edge with little margin for error.
If there is one message BAYAN, whose name translates as “prosper”, could carry with him, I am sure it would be something like this:
“Migratory birds like me don’t recognise human borders. We travel around the Earth, crossing oceans and deserts, powered sustainably by caterpillars, just to survive and breed. As humans, you are changing the planet in profound ways. Please ensure there are places for us to rest and refuel along the way so that we all may prosper.”
The fact that we last heard from BAYAN close to Kunming, Yunnan Province in China is fitting. Next year, this city is due to host the 15th Conference of the Parties (COP15) to the United Nations Convention on Biological Diversity, at which governments are due to agree a “new deal for nature” including targets to slow and reverse the loss of biodiversity. In many ways it is the most important meeting ever on nature.
Wouldn’t it be good to think that BAYAN’s legacy is to send his message to delegates to the UN meeting in Kunming?
Thank you to everyone who has supported, followed and engaged with Баян (BAYAN) and the other Mongolian Cuckoos during this project. You have all helped to raise awareness about migratory birds and the places they need.

Last week I was honoured to be invited to deliver a series of lectures about biodiversity to more than 3,500 students at schools in Chengdu, the capital city of Sichuan Province. Inspired by China hosting the United Nations Conference on Biological Diversity in October 2020, the local government commissioned these lectures to raise awareness of biodiversity among its students and to advance the students’ English language skills.
Of course, these students are lucky to live in Sichuan Province, an area with some of the most biodiverse temperate forests in the world (thanks to being shielded by the mountains during the last ice age). There are many mammals, birds and plants that are found nowhere else on Earth.
As is often the case when speaking to students in China, I was immensely impressed with their work ethic (they get up at 0630 and study until 2130 every day), their enthusiasm for nature and their creative ideas about how to make a difference.
After each lecture, the students were given an assignment to find out about a species of mammal, bird or plant found only in Sichuan, to write about why it is special and to set out their ideas for how to ensure it is protected. Over the next few weeks, we’ll be reviewing the submissions and selecting the best to be recognised by the government.
Huge thanks to 新东方 (New Oriental) for making the arrangements.
The lectures were delivered to the following schools (in a mixture of Chinese and English):

成都外国语学校高中部 – Chengdu Foreign Language School (High School)
实验外国语学校初中部 – Experimental Foreign Language School (Junior High)

When you think of Beijing, what image comes into your head? The Great Wall? Maybe Tiananmen Square? Or maybe air pollution? For those of a more mature generation, maybe even the picture of a city full of bicycles..? Whatever the image, I suspect that for most people, birds or wildlife might not be front and centre.
That could be about to change.
In 2020, Beijing will host the Conference of the Parties to the UN Convention on Biological Diversity (CBD). This clumsily-named UN convention meets every two years and I suspect most people not directly involved with the process would be hard pressed to say much about any of the previous meetings or what has been achieved. However, the 2020 meeting promises to be different. It is the time when governments are due to conclude an agreement on targets and measures to slow, stop and eventually reverse the loss of wildlife on Earth.
The meeting will take place in the context of the most recent Living Planet index showing that, since 1970, we have lost more than 60% of the animals on our planet. That is a shocking statistic and should be a wake-up call for governments and the public everywhere.
As host of the CBD, the Chinese government will want a successful outcome and, with recent progress towards President Xi Jinping’s vision of ‘ecological civilisation’ including a ban on further reclamation of intertidal mudflats and nomination of key coastal wetland sites for World Heritage status, the creation of a national park system, species-specific conservation work, e.g. on Baer’s Pochard and Scaly-sided Merganser, the country is creating the foundation for a positive story to tell.
But what about the host city? Could hosting the CBD be an opportunity to change the global image of Beijing from one of a crowded, polluted, grid-locked city to one of the world’s best capital cities for wildlife?
Beijing is already one of the best major capital cities in the world for birds, with around 500 species recorded. And in case the Mayor of Beijing is reading, here are some ideas that would require very limited resources but which could have a major impact on Beijing’s image:
Idea 1: A world-class wetland reserve in Beijing
Wouldn’t it be wonderful if Beijing had a large waterbody that could be an important stopover site for migratory birds, including cranes, geese, ducks, shorebirds and others? Well, just 75km from Tiananmen Square lies Miyun Reservoir. It is Beijing’s largest drinking water reservoir and, until public access was prohibited in April 2016, it was the best birding site in the capital attracting flocks of cranes, bustards and large numbers of waterfowl, not to mention huge numbers of buntings in winter. However, after a large fire in the area and concerns about water quality, much of the land around the reservoir – ideal habitat for shorebirds, cranes, bustards, birds of prey, buntings and pipits – has been cleared and planted with mostly non-native trees in monocultures. This policy has undoubtedly had a negative impact on birds. Whilst it is understandable to prioritise water quality, this need not be at the expense of wildlife. Internationally, there are examples of reservoirs being managed for both water quality and wildlife. One example is Rutland Water, England’s largest drinking water reservoir. In fact, Rutland Water is managed for three objectives – water quality, birds and recreation. If we can share this experience and demonstrate that a large water body can be managed as a place for wildlife as well as water quality, there would be an opportunity to develop a management plan for Miyun Reservoir that maintained a high standard of water quality whilst attracting world-class numbers of cranes and other waterbirds and providing limited public access, attracting millions of visitors each year and an associated boost to the local economy. Given the CBD conference will likely be in the last quarter of the year, the Beijing government could even invite international media to see the large flocks of cranes that would almost certainly be present if the area was managed sympathetically.
– High standard of water quality
– Providing a refuge for thousands of waterbirds, including threatened and endangered species such as cranes and bustards
– Providing opportunities for the urban population to connect with nature
– Through the visiting public staying in local hotels and eating in local restaurants, bringing income to the local people in relatively poor Miyun county
Idea 2: 10% Wild
Beijing enjoys some large and expansive green spaces. Parks such as the Temple of Heaven, Summer Palace, Yuanmingyuan (Old Summer Palace) and the Olympic Forest Park are all hugely popular places providing urban Beijingers with opportunities to enjoy the outdoors. Anyone who has visited these parks will know that they are heavily manicured with an army of staff ready to collect any leaf that falls or any blade of grass that grows in one of the cultivated flower beds. These parks are over-managed to the extent that they are not as friendly for wildlife as they could be. One idea is for the management of these spaces to leave “10% wild”. This would mean no significant active management of an allocated part of the park – no use of insecticides, no removal of native plants and no cutting of grass or removal of fallen leaves. Each park could partner with a local school, the students of which would be invited to undertake surveys of biodiversity – insects, birds and plants – and compare the “10% wild” with other managed parts of the park. Interpretation signs around the allocated area could promote this experiment to visitors, publishing the results of the student surveys and helping to engage the public about wildlife. After two years there could be a review to assess the results and to explore whether the experiment should be expanded.
– More and better habitat for wildlife in urban Beijing
– Students at local schools become citizen scientists
– Public engagement on the role of parks in providing homes for wildlife in cities
– Fewer resources needed for park management
Idea 3: Urban wildlife oases
Beijing lies on the East Asian-Australasian Flyway and, every spring and autumn, millions of birds pass the Chinese capital on their way to and from breeding grounds to the north and wintering grounds to the south. To make these remarkable journeys, birds require places to rest and refuel along the way. The trans-continental journeys, such as those of the Beijing Swift and Beijing Cuckoo, are challenging for the hardiest of birds, and the challenges are only increased as vast areas of natural habitat along migration pathways are altered or eliminated, making it difficult for exhausted birds to find suitable places to rest and refuel.
“Urban wildlife oases” could provide ‘stepping stones’ for migrating birds to cross urban areas where there is limited quality habitat. Each community has the potential to provide important habitat for native birds – and a richer, more beautiful place to live for people.
To illustrate the potential, I’d like to convey my experience with a patch of land close to my apartment in Shunyi District. Surrounded by new developments, including apartments and shopping malls, this 1km x 1km patch of land, very close to the airport, has yet to be developed and, in the two years since I moved to the area and in almost 100 visits, I have recorded 156 species of bird, five species of mammal and nine species of butterfly. Highlights have included Band-bellied Crake, Pallas’s Rosefinch, Siberian Thrush and Rough-legged Buzzard, demonstrating the importance of the site to migratory birds.
Maintaining a patchwork of urban oases across the city, potentially with some limited public access, would cost little – beyond the opportunity cost of the land – and provide significant benefits to both wildlife and people.
– providing shelter and food for some of the millions of migratory birds that pass through the capital each spring and autumn; plus important areas for breeding and wintering species
– with limited public access, these sites could provide the public with access to wild spaces and places for students from local schools to become citizen scientists
– interpretation would mean that these urban oases could act as outdoor classrooms for Beijing’s urban population
Idea 4: Adopting the Beijing Swift
In 2015, a project involving Beijing Birdwatching Society and international experts discovered, for the first time, the migration route and wintering grounds of the Beijing Swift (Apus apus pekinensis). It was a hugely popular story, covered by mainstream media – both print and broadcast – and engaged millions of people, most of whom would never ordinarily take an interest in birds. The Beijing Swift is the perfect symbol for modern Beijing. One of the old names for Beijing is Yanjing, which, in Chinese, breaks down to “燕” (Yan) and “京” (Jing). The first character, “燕” means “swift” or “swallow”, so the name Yanjing could be interpreted as “Swift capital”. This bird also links China with Central Asia, the Gulf and Africa, aligned with the much-touted “One Belt, One Road” initiative to revive old trade routes. Why not formally adopt the Beijing Swift as the official bird of the Chinese capital? There can be no more appropriate candidate.
– Associating Beijing with a bird of endurance, elegance and global reach
– Greater public awareness about the wildlife of Beijing
– Encouragement to businesses and communities to help stem the decline of the Beijing Swift – caused by the demolition of traditional buildings – by erecting artificial nest boxes at suitable sites and encouraging the inclusion of Swift-friendly designs in new buildings
Idea 5: Removing the invisible killer: mist nets at China’s airports
When thousands of environmentally-minded people arrive in Beijing for the UN Conference on Biological Diversity, the first thing they will see is lines and lines of mist nets alongside the runway at Beijing Capital International Airport, many of which will hold bird corpses dangling in the wind. China’s policy to address the (serious) risk of bird strikes is to line each runway with several kilometres of mist nets. This method is only effective against small birds which, unless in large flocks, represent almost no risk to aircraft. Nets at ground level are ineffective against the more significant risks associated with flocks of large birds such as geese, swans or herons. In fact, guidance by the International Civil Aviation Organisation (ICAO) makes no mention of mist nets as a way to mitigate the risk of bird strikes. Recommended good practice is to undertake a risk assessment at each airport to identify the unique risks from wildlife and take appropriate measures to address these specific risks. Non-lethal methods such as managing habitat, playing distress calls, using birds of prey etc are the most effective methods. China, with more than 300 airports, takes a general approach of simply erecting lines of mist nets. It’s lazy and ineffective. Could CBD be the catalyst for a review of this policy?
– stopping the unnecessary killing of millions of birds each year
– more effective management of the risk of bird strikes
– a better international image for China and Beijing
With two years to go until Beijing hosts what will probably be the world’s largest governmental conference on biodiversity, there is ample time to develop a strategic plan that would make Beijing one of the world’s most wildlife-friendly cities. Instead of “smoggy Beijing”, wouldn’t it be wonderful to be able to label Beijing as the capital of ecological civilisation? These are just five ideas. If you have more, please comment and let us know.. you never know who might be reading.
