Amazing, look at the size of their legs and talons. We actually have a species of sea Eagle in the UK, the White Tailed eagle, but only really in Scotland these days and the numbers are low compared to what they will have once been.
It's the same with Golden Eagles, we used to have them in England(the Lake District in fact), but due to being persecuted by man(or better said, morons), there are none left now. The last one went missing a few years ago(probably died of old age) and hasn't been seen since. Unfortunately, they were unsuccessful in introducing a mate to him, so he weren't able to reproduce. The numbers in Scotland are rising which is good news, but we have none left now in England. Maybe one day they will try and reintroduce them like they have done successfully with Red Kites.
