09 Jun 2023 - The end of the road for Cuckoo JAC
We are very sad to report that we have heard the last from Cuckoo JAC.
JAC, named in loving memory of Professor Jenny Clack, was tagged at World’s End near Llangollen on 1 June 2021. Since then we have had the privilege of tracking him over two full migration cycles from Wales to Africa and back.
His route south across the Sahara took him via Algeria and Mali to the Sahelian areas of Burkina Faso or Niger. He then spent some time in northern Nigeria before heading on to the Congo. On his return migration north, he visited West Africa where he stopped in Ivory Coast in 2022 and Guinea in 2023, arriving back in Llangollen around the end of April each year.
The diagnostic data received from his tag shows the recorded temperature dropping and this, along with the fact that he appears to have been stationary for quite a while, suggests that he has perished (rather than there being a tag failure).
He has made a very valuable contribution to our growing knowledge of Cuckoo ecology and we will miss reporting on his movements.
