Updates from our Cuckoos

Read the latest updates from our Cuckoos on their migration.

Clive lost in the desert

27 Sep 2021
As those of who have been following our work for a while will know, we discovered that Cuckoos breeding in the UK migrate to Africa via two main routes. Birds either migrate southwest via Spain and Morocco (the ‘western route’) or southeast via Italy or the Balkans (the ‘eastern route’) before converging in the Congo basin of central Africa. Our studies have shown that birds on the western route are significantly more likely to die before completing the Sahara crossing (even though their route was 12% shorter to this point). Very sadly, the western route has now claimed two more casualties, Harry and Clive. Clive pushed south from Morocco to Mauritania on 29 August. He then moved about 55km shortly after but the latest data shows Clive in the same place, suggesting that he has also died. These two birds have probably now made their last contributions to our growing knowledge of Cuckoos and the amazing migrations they undertake.

Clive is crossing the Sahara

01 Sep 2021
Clive is clearly a cool character, preferring to arrive fashionably late to the party. While the other Cuckoos were well into their journeys south, he held on in northern Spain until 25 August. Once he got moving, he didn't hang about. At 08:19 on 25 August he was in central Portugal and by 11:00 he had made it as fas as southern Portugal. He didn't stop there though and by 09:58 the next morning (26 August) he had crossed to Africa, making landfall close to the port city of Safi in Morocco. He continued down the west coast of Africa that day and by 22:10 that evening he was 118 km further south. We next heard from Clive during the evening of 28 August (Saturday) by which time he was in the Akchar desert, approximately 150 km south west of the Richart Structure (the eye of Africa). A couple of recent further updates show him in the same location. This isn't a very hospitable place for a Cuckoo so hopefully we will see a new update from further south soon. He is currently 221Km north of Harry's location. 

Clive still in Spain

22 Aug 2021
An update from Clive's tag got us excited last week as it suggested he may be crossing the Sahara. However, that lower quality signal has since been followed with several high quality updates from northern Spain, showing that Clive hasn't yet made his move to Africa and remains close to Torrelavega in Spain.

Clive heads east

03 Aug 2021
Cuckoo Clive has been on the move but is still in northern Spain. Having flown 300 Km (186 miles) north west towards Vilalba in Galicia, he has since flown 278 Km (173 miles) east and is now just outside Torrelavega.

Clive turns north

29 Jul 2021
Over the last week or so Cuckoo Clive has been making his way steadily west from Villoslada de Cameros in La Rioja, Spain to Valladolid. New updates received this morning show that he has now turned north, flying 300Km (186 miles) north west towards Vilalba in Galicia, north west Spain. His last locations showed him near a wind farm above the villages of Sisalde and Pardela. 

Clive moves on to Spain

20 Jul 2021
Clive didn't stay in Brittany for long, new updates received just after 7am this morning showed that he has flown 700Km (435 miles) south to northern Spain. He is now in a woodland close to the town of Cevico Navero in Palencia. He is 81 km south west of Cuckoo PJ and 144Km north of Cuckoo Harry. 

Clive makes his move

18 Jul 2021
Cuckoo Clive has taken advantage of the fine weather and crossed the Channel. New updates received at 05:05 this morning (Sunday 18 July) showed that Clive had flown 437 km (271 miles) south-south west and was in the north western part of the Morbihan department of Brittany, between Cleguerec and Plouray. 

Introducing Clive

17 Jun 2021

Clive was caught during an early morning session during less than ideal conditions, with the wind blowing and forecast for it to increase to gale proportions in a few hours’ time. A Cuckoo soon came to investigate but flew away. Hopes were dashed but the tagging team kept their nets open and it wasn’t long before a Cuckoo flew towards the nets and straight in! Clive has remained at this site in Worcestershire since being tagged.
