Updates from our Cuckoos

Read the latest updates from our Cuckoos on their migration.

Ripple moves south in Spain

16 Aug 2022
Ripple has flown 100km south from his last location in and by the early hours of this morning was approximately 7km (4.3 miles) south east of the town of Puebla de Sanabria in the province of Zamora in the autonomous community of Castilla y León. Is this the start of Ripple's big flight south to Africa? Stay tuned to find out!

JAC moves east in Nigeria

15 Aug 2022
Since our last update, JAC has flown approximately 300km (186 miles) east towards north central Nigeria. His route took him to Kamuku National Park and he has since flown a further 30km east. He is now in north west Kaduna state, approximately 90km north west of the city of Kaduna.  

We have lost Calypso

12 Aug 2022
We are sorry to report that we have lost Worcestershire Cuckoo Calypso. Our last good quality signal from Calypso's tag was received on 24 July when he was in northern Italy and although we have had a couple of signals since ,they have been low quality and from the same location. Having reviewed the diagnostic data from the tag we could see that between 26 & 28 July, the battery charge dropped substantially and the temperature reading dropped by 5C, neither of these are good signs. It also seems strange that his last locations were in the middle of an urban area when there is so much apparently suitable natural habitat surrounding it. All of this means that sadly  it looks like the end of the road for Calypso, but he has given us some excellent data including of course a complete migration cycle between Worcestershire and the Congo Basin. 

JAC flies from Benin to Nigeria

10 Aug 2022
JAC's visit to Benin was brief as new updates received last night show that he has flow 186km(116 miles) south east, taking him over the border into Nigeria. He is now in north western Nigeria, on the edge of the Illoka Oje Forest Reserve. Last year JAC spent almost two weeks in western Nigeria before moving further east into north central Nigeria where he remained until early October. He then moved directly to the Congo Basin where he spent the winter. 

JAC visits Benin

08 Aug 2022
After a brief visit to eastern Burkina Faso, JAC has hopped over the border into Benin. He is now in the W National Park in the far north of Benin, close to the Mekrou River which separates Benin from Burkina Faso. 

Saying goodbye to JD

08 Aug 2022
In our previous update, we shared with you that strong winds had carried JD 300 miles (482 km) out to sea, from the coast of Western Sahara towards the Cape Verde archipelago. Against all the odds, he made it back to the African mainland, raising hopes that this Norfolk bird's watery detour had not put an end to his journey to the Congo basin. Sadly, however, it appears that JD has perished as no further updates have been received since the last signal from his tag on 24 July, shortly after he made landfall close to the port of Nouadhibou, Mauritania’s second city. Having lost sight of land while out at sea, JD had returned the way he came. Without a ‘mental map’ to follow, he couldn’t have known that flying due East would have meant a considerably shorter journey and perhaps a better chance of survival. As it is, JD’s energy reserves appear to have been exhausted, sadly leaving him unable to find food or, perhaps, at greater risk of predation. No matter how long we are able to follow each Cuckoo, the data they provide contributes to our growing understanding of these remarkable birds and how we can work to protect them – JD and his adventures are no exception.

Daniel is crossing the Sahara

08 Aug 2022
Over the last few days Daniel has made his next big move south, leaving southern Europe and entering Africa. Last year Daniel remained in northern Italy until 12 August when he crossed the Sahara to arrive in eastern Mali where he remained until 29 August when he moved east into southern Niger. This year his journey took him from southern France to southern Sardinia where he spent some time in the Campanasissa Cadelano Forestry. He then proceeded south over the Sahara and by yesterday morning (7 August) had reached south eastern Niger. New updates received this morning show that he hasn't moved far overnight and he is some 320km north east of Lake Chad. Given that there seems to be little of use to a Cuckoo in this area we will be anxiously awaiting further updates from Daniel's tag. 

Victor II crosses the Sahara again

08 Aug 2022
Over the last few days Victor II has finally left the Austrian Alps and flown into Africa. By Thursday morning (4 August) he was passing over central Italy and by Saturday evening he was flying over the Libyan Sahara. He has since flown south west into Niger and by yesterday evening (7 August) he had reached southern Niger. Over the last few days he has flown approximately 3,663km (2,276 miles) and he is now approximately 130km east of the town of Dakoro. Last year Victor II arrived in southern Niger on 30 July and remained here until the end of August when he moved further south within the country. He then remained here until moving to Cameroon in mid October. He is currently close to the area he stopped off in last year so hopefully he will find some good places to rest and recover from his arduous desert crossing.  

Farewell to Charles

28 Jul 2022
Sadly it is time to say goodbye to Sussex Cuckoo Charles. We followed Charles over 4,000km (2,485 miles) from his breeding grounds on the Knepp Estate south through France and Spain and into Africa. He seemed to be making such good progress but unfortunately was beaten by the Sahara. As he approached the border between Algeria and Mali he veered off course, drifting south west across the desert. Had he been able to keep going south he would've reached the River Niger within 370 miles where he would have found good feeding opportunities. Instead he travelled 410 miles and perished, still in the desert on the border between Mali and Mauritania. He is gone but not forgotten and the data he provided us with will contribute to our growing knowledge of Cuckoos and the pressures they face.

Bluey moves east into Mali

28 Jul 2022
Having spent the last few weeks in south eastern Senegal, Bluey has flown 167km (104 miles) south east over the border into south western Mali. He is now 33km (20 miles) south of the rural town of Kenieba in the Kayes region of SW Mali.
