Mongolian Cuckoos Cross The Arabian Sea, Enchanting A Nation

Thanks to modern technology, we are beginning to unlock the secrets of our migratory birds.  And, although removing some of the mystery, gaining knowledge of these journeys in no way diminishes our awe at what these birds achieve in terms of endurance and navigation.  Every year, a new generation of birds following in their predecessors wing-flaps, inspires a new group of people. 

When it all began in June 2019, one of the aims of the Mongolian Cuckoo Project was to engage the public about migratory birds and the places they need.  Knowledge and experience are the first steps towards falling in love with nature and, as Baba Dioum, the Senegalese conservationist famously said: 

“In the end, we will conserve only what we love; we will love only what we understand and we will understand only what we are taught.”  

Thus, connecting more people to nature is crucial if conservationists are to build support for more, and better, protection of species and the wild places they need.  With biodiversity in crisis (according to The Living Planet Index, compiled by several leading wildlife science organisations, the populations of vertebrates have fallen, on average, by around 60% since 1970), there can be no more important task.

That is why the engagement inspired by ONON and BAYAN, two Common Cuckoos fitted with transmitters in Mongolia in June 2019, has been so up-lifting.  Over the last seven days these cuckoos, named by schoolchildren in northern Mongolia, have crossed the Arabian Sea from Africa (Kenya and Somalia, respectively).  As I write, ONON is in Bangladesh and BAYAN just 30km northwest of Kolkata in West Bengal, India.  That means that, since 29 April, ONON has flown >6,300km, and BAYAN >5,800km in just under seven days.

Tracks show data from 29 April to 6 May 2020. ONON in red and BAYAN in green.
As of late on 6 May 2020, ONON was in Rajshahi Division, Bangladesh and BAYAN just northwest of Kolkata in West Bengal, India.

Thanks to the wonders of modern technology, each step of the journey has been published in near real time, allowing followers to track the progress of the birds as they headed out over the open ocean towards India.  And, as they did so, interest in India soared…  With huge thanks to Parveen Kaswan of the Indian Forest Service, ONON and BAYAN now have thousands of new followers in India.  Parveen has more than 130,000 followers on Twitter and, when he sent out a message about ONON making landfall in India, interest exploded.  

Many people were stunned that a cuckoo could make such a flight and asked questions, which I did my best to answer!  See the end of this post for a selection.  Parveen’s tweet also inspired an article in the Bangla version of the Indian Times, under the title “Migrants from Kenya to Madhya Pradesh in a Week”.

One follower, Rajesh Ghotikar, who lives close to Ratlam in Madhya Pradesh, even went out to check on ONON’s location, taking precautions and respecting local rules on mask wearing and social distancing as he did so.

I’ve been so impressed by the interest and, most of all, by the warmth, politeness and friendly nature of the Indian people who have engaged with these birds.  It is moments like this that make the project so worthwhile.  Having never had the pleasure to visit the country, I am beginning to see why it is known as Incredible India.

Once again, huge thanks to the Mongolian Cuckoo Project team, especially Nyambayar Batbayar, Tuvshinjargal Erdenechimeg, Batmunkh Davaasuren, to Chris Hewson from BTO and to Dick Newell and Lyndon Kearsley.  And big thanks, too, to the Oriental Bird Club for generously sponsoring the project.

  1. Amazed… Wish we could see their flight as it happens… Would teach us a lot about riding the wind currents…
