Updates from our Cuckoos

We are sorry to report sad news about Selborne. We last heard from Selborne at midday on 4 April when he had just arrived in Spain and it now looks as if he died later that day or overnight. His last location shows him over a southern ridge of the Sierra Morena mountains where it appears that he was stopped suddenly in his tracks as he topped that slope. We will probably never know what happened to Selborne but it would appear most likely that he was either taken by an avian predator or succumbed to human hunters. Selborne was named by the Hampshire Ornithological Society when he was tagged in June 2016. Since then we have followed Selborne over two complete migration loops from Hampshire to his wintering grounds in Gabon. He was only 1,430 Km (888 miles) from completing his third migration loop. We are grateful to the Hampshire Ornithological Society and all of Selborne's sponsors for enabling the wonderful contribution that Selborne has made to advancing our understanding of Cuckoo migration.

When we last heard from Robinson, he was in southern France, near the town of Labatie d'Andaure. At 21:07 last night we received an update from his tag that showed he had covered the remaining 1,000 Km (622 miles) of his return journey and he is now in the area he was tagged, near Budby in Nottinghamshire.

PJ completed the final leg of 645 Km (400 miles) of his return journey at 15:30 yesterday afternoon and is now back in the King's Forest in Suffolk. PJ was tagged in June 2016 so his successful return this year means that we have now tracked him over three complete migration loops from his breeding grounds near Thetford to his wintering grounds in Angola and back again. In previous years PJ has departed between June 23 and July 2 so we expect him to stay with us for around 9 weeks.

The latest updates from Carlton II's tag received at 08:00 this morning show that he has progressed north into west central Spain. He is now in Extremadura, near the small town of Torremenga.

Updates received early this morning brought the news that the first of our satellite-tagged Cuckoos had made it back to the UK. Cuckoo Knepp, tagged on the Knepp Estate in Sussex last May is back in Sussex! We last heard from Knepp on April 17 when he was on the northern edge of the Atlas mountains in eastern Morocco. He was in the northern Sahara, near the oasis settlement of Ain Bni Mathar. Since then he has flown 1,880 Km (1,170 miles) north to reach his breeding grounds on the Knepp Estate. We hope that this is the first complete migration loop of many which we will follow Knepp on.

Thomas has pushed north and made it into Spain. He is currently to the southwest of Gibraltar and the south of Algeciras, and only 2km (1.5 miles) from the coast.  

Over the Easter weekend Robinson crossed the Mediterranean, seemingly just to the west of Sardinia, involving a 780km (485 miles) sea crossing. He is currently in Ardeche north of the town of Labatie d'Andaure. As the Cuckoo flies he is around 1,000km (619 miles) from his Sherwood Forest breeding site.

When his tag powered up on 18 April he was to the west of Madrid, central Spain. However, when his tag came on again around breakfast on 23 April he had left Spain and was in western France close to the town of La Roche-sur-Yon. This will automatically update on his map overnight. He is now only 658km (409 miles) from his Thetford Forest breeding site.

Lambert began his desert crossing around 9.00am on 19 April and 24 hours later was 1,295km (805 miles) into the crossing and still going. By 9.00am on 21 April he had made it and was in northeastern Algeria and on the northern edge of the desert. His crossing speed was 68kph (42mph). He is currently in farmland to the south of the town of Chettouane Belaila.

Over the Easter weekend we received a series of locations showing Carlton II heading across the desert and by early evening on 20 April he had made it to southern Morocco. He didn't hang around though as by the evening of 22 April he was in southern Spain, just to the north of Marbella. During this movement he has flown 3,283km (2,040 miles).
