From the BBC series The Highlands, narrated by Ewan McGregor. From their site:
Ospreys are a great conservation success story in the Highlands. The programme follows the trials of this family from the parents’ return from their wintering grounds in Africa until the chicks fledge.
Once an osprey grabs hold, they can sometimes be pulled underwater by a large fish. Lots of wonderful still photos from the series as well.
