they showed this in the news over here, for the second year since the Dark Ages a couple of fish eagles have built a nest in the province of Flevoland, Netherlands. I am not sure if they are indeed fish eagles or some other kind, I hope someone can help here!
This is the link for WMP: http://www.staatsbosbeheer.nl/actueel/zeearend/media/zeearend.asx
This is the official website, in Dutch and often it doesn't show the webcam when it's busy, though it will work in WMP.
Edited: White-tailed eagle, according to Swift Thanks Swift and Pete as well, I will check the bird id forum as well
