White-tailed sea eagle
White-tailed sea eagles are the largest of all European eagles and are broader and more vulture-like than golden eagles.
The birds were widespread in Scotland and Ireland but, following persecution, they became extinct in Britain in 1916.
They were reintroduced to the island of Rhum in 1975 and are now scattered along the west coast of Scotland.
White-tailed sea eagles are up to 91 centimetres (cm) long, with a wing span of up to 245cm. They weigh up to seven kilograms.
One of the chicks bred at Belfast Zoo was part of a successful reintroduction programme in Israel.
