Earlier this month we began a poll to see where readers think NOMAD, the first Oriental Cuckoo (Cuculus optatus) to be tracked, would spend the northern winter. The poll closed on 10 September and here are the results:
Indonesia/Malaysia – 39%
Africa – 27%
Australia – 13%
India – 8 %
New Zealand – 5%
Other – 8%
Perhaps not surprisingly, SE Asia is the most popular suggestion. However, with one specimen from Zambia (per Handbook of the Birds of the World), and eBird records from Australia and New Zealand, there remains a large element of mystery about where NOMAD will go.
Having spent the breeding season on the Central Siberian Plateau, NOMAD is now well on his way south and is currently in China’s Shanxi Province.
The migration tracks of the Mongolian Cuckoos. NOMAD’s migration is represented by the dark blue line. Zoom into the map using + and – to see more detail.
NOMAD’s migration so far isn’t giving much away but if he remains healthy for the next month or so, we should finally discover his destination. You can follow the progress of NOMAD, and all of the cuckoos tagged in Mongolia, by regularly visiting this dedicated page or the map on the BTO’s website. For Twitter users, follow @BirdingBeijing for near real-time updates of significant moves.

Back in June, in partnership with the Wildlife Science and Conservation Center in Mongolia and BTO and kindly supported by the Oriental Bird Club and Dick Newell, ‘Team Cuckoo’ visited Khurkh ringing station to catch and fit tags to five cuckoos as part of the Mongolian Cuckoo Project. Incredibly, the first cuckoo to be caught was an Oriental Cuckoo and the BTO’s Chris Hewson duly fitted a tag. As fas as we know, this is the first ever Oriental Cuckoo to be tracked.
After spending the summer on the Central Siberian Plateau in Krasnoyarsk, Russia, NOMAD – as he was called by local schoolchildren – is now well on his way south. As of 3rd September 2019 he has re-crossed the Russia-Mongolia border and is now just 80km north of Ulaanbaatar.
Assuming he stays healthy, the next few weeks and months will reveal, for the first time, the wintering grounds and migration route of Oriental Cuckoo.
So, just for fun.. it’s time to place your bets!
Where is NOMAD going?
The poll will be open until Tuesday 10 September, after which the results will be revealed. Thank you for voting!
Back in early June, five cuckoos were fitted with tags at Khurkh Ringing Station in Mongolia. The first one fitted with a tag was an Oriental Cuckoo (Cuculus optatus), believed to be the first ever individual of this species to be tracked. The other four were Common Cuckoos (Cuculus canorus). All five were given names by schoolchildren in the local community and in Ulan Bataar.
The next six weeks were fairly quiet for the four Common Cuckoos, all of which remained in the vicinity of Khurkh. However, the Oriental Cuckoo (named NOMAD) was clearly still on migration when he was caught in early June and continued north to breeding grounds on the central Siberian plane.
Now, into August, the cuckoos are already on the move. NOMAD, after only four weeks on his breeding grounds in central Siberia, has begun to move south and is currently close to the border of Irkutsk Province in Russia. Three of the four Common Cuckoos (NAMJAA, ONON and Captain KHURKH) have also begun their journey south with only BAYAN remaining in the vicinity of Khurkh. After being tagged within a few kilometres of each other, more than 2,800km now separates the five birds.
Over the next few weeks and months, following their progress is sure to be a roller-coaster ride. We expect the four Common Cuckoos to head into south Asia before crossing the Arabian Sea to Africa. However, the migration route and wintering grounds of NOMAD, the Oriental Cuckoo, will be new to science. From sight records we believe NOMAD’s most likely destination is southeast Asia or possibly Australia. However, nobody knows for sure, and one thing is for certain.. there will be some surprises along the way!
The schoolchildren in Mongolia are excited to follow ‘their’ birds and already the project has reached many who wouldn’t ordinarily take an interest in migratory birds.
If you enjoy following these birds, please consider making a donation, no matter how small, to the JustGiving site towards the ongoing satellite fees. All contributions will go directly to BTO and 100% of the funds will go towards the cost of the satellite fees only.
Big thanks to the project partners, the Mongolian Wildlife Science and Conservation Center (WSCC), the British Trust for Ornithology (BTO) and to the Oriental Bird Club (OBC) and Mr Dick Newell for their financial support.
Thanks also to you, the reader, for following the Mongolian Cuckoos. Isn’t migration amazing?
