From Jake Grives-Cook:
Good morning, yesterday afternoon I was at Picton Point on the Cleddau
estuary and I believe I saw a White-tailed eagle. It was being harrassed
by gulls while flying high above the river and quickly climbed to a
higher altitude and soared off. I saw it with my naked eye so I did not
get a close-up view but over the years I have often watched African
fish eagles (Haliaeetus vocifer) in flight and my initial thought was
that it was a Fish eagle possibly escaped from a bird of prey centre but
then its huge size made me think it was a White-tailed Sea eagle
(Haliaetus albicilla).
