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.
21 Aug 2019 - Valentine moves north in Burkina Faso
In the last couple of days Valentine has flown 74 km (46 miles) north west from his last location towards the border with Mali. He is now close to the city of Solenzo in the far west of Burkina Faso.
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.
29 Jul 2019 - Valentine moves to south-west Burkina Faso
Over the last few days Valentine has flown 322 km (200 miles) south west into south-western Burkina Faso. He is now in the Hauts-Bassins region, 55 km (34 miles) north-east of the region capital, Bobo Dioulasso.
22 Jul 2019 - Valentine has crossed the desert
Since our last update Valentine has become the second of our tagged Cuckoos to successfully cross the Sahara. From his location in Morocco he has flown south east into Algeria and then due south over Mali to Burkina Faso. He is currently in the Rollo Department, a commune of Bam Province in north-western Burkina Faso. He is 125 km (78 miles) north of the capital Ouagadougou.
