"Dear John
We are sorry to report that we have sad news about Hampshire Cuckoo Selborne.
We last heard from Selborne at midday on 4 April when he had just
arrived in Spain. Unfortunately it looks as if he died overnight 4 - 5
April. His last location shows him over a southern ridge of the Sierra
Morena mountains and it looks as if 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."
