White-tailed eagles - also known as sea eagles - are the UK's largest birds of prey and were a common sight across Scotland until they were persecuted to extinction.
Between 2007 and 2012 a reintroduction programme saw 85 birds released on the east coast of Scotland.
In 2013, for the first time in almost 200 years, sea eagles bred successfully in East Scotland, although last year's chick disappeared in April.
The nest in Forestry Commission Scotland woodland in Fife was built by a pair, known as Turquoise 1 and Turquoise Z after their wing tags. They had been released in 2009 as part of the reintroduction project.
A nestwatch programme manned by more than 20 volunteers has been set up to ensure the protect the site.
