Carlton II's movements

30 Sep 2019 - Carlton II pushes East to Nigeria

Carlton II has started the next stage of his migration, leaving his last location in Mali and flying 1,434 km (891 miles) East to Nigeria, via a brief stop-off in Benin. Carlton II is now in the Dagida Game Reserve in western Nigeria. In 2018, Carlton II spent two and a half weeks in this game reserve from mid October to early November before pressing on through Cameroon to Gabon, where he spent the winter.

09 Sep 2019 - Carlton II crosses into Mali

Over the weekend Carlton II left Senegal and has flown 534 km (332 miles) east into Mali. He is now in the south eastern part of the Kayes region of Mali, approximately 145 km (90 miles) north west of the capital, Bamako. Cuckoos Valentine and Senan are over the border in Burkina Faso while PJ and Tennyson are more than 1,500 km further east in Nigeria. 

04 Sep 2019 - A challenging autumn migration

The last few weeks have been quiet and for those who had not yet completed their desert crossings, it looks like the challenging conditions have claimed more of our tagged Cuckoos.

Unfortunately no further signals have been received from Knepp. From the temperature data and movements at the time, he was alive on 12 July, when we last heard from his tag. Though the battery charge had been low for a few days, there is no evidence of long term battery decline so we can't be sure what has happened to him - either he, or the tag, appear to have died suddenly. 

Lambert, who was still in France, has not moved on south and signals on 21 August showed high temperature fluctuations across the day, indicating the bird's body temperature and behaviour were not regulating it. We've heard nothing since then, and his tags battery charge had suddenly dipped, all of which leads us to believe he has likely died.

Unfortunately the challenging conditions have also impacted on Nussey who has already attempted two trips to Africa and retreated to Europe.  Abnormally low temperatures were received at the time of the last messages (16 August), having previously been fine. He was not migrating at that time, so the low temperatures were not due to high altitude, and the battery was also much lower than previously, further suggesting he was dead.

The droughts and exceptionally high temperatures in Europe appear to have proved difficult for our Cuckoos this year, however the five south of the Sahara are still regularly transmitting. Valentine, PJ, Carlton II and Tennysons' tags have all sent signals during September and the last signals received from Senan's tag were at the end of August and show him still in Burkina Faso.

15 Aug 2019 - Carlton II in Guinea Bissau

Since our last update Carlton II has moved around 100 km (62 miles) east from his last position in Senegal and is now just over the border in Guinea Bissau. He is now in the far north-eastern corner of Guinea-Bissau. Last year he began moving west on August 11 so this could well be the start of his journey through west Africa towards his final wintering grounds in Gabon.  

14 Aug 2019 - Five across the desert

So far this year, five Cuckoos have made it successfully across the desert. Carlton II, PJ, Senan, Tennyson and Valentine are all south of the Sahara and still sending regular tag transmissions. They still have a little further to go south before reaching their final wintering destinations.
