The migratory bird of prey has returned to RSPB Scotland's Loch Garten reserve, near Grantown on Spey, for its 14th season.

Reserve staff have compared her seasons to a TV soap.

It's the fifth coin portrait to have been created during the Queen's reign.

Brian Buckle of Fishguard was convicted of child sex abuse in the 1990s, when his victim was aged between eight and 10-years-old.
Swansea Crown Court sentenced him to a combined 33 years in prison, to be served over a 15 year period.
He was found guilty of 16 counts of non-recent sexual abuse against a child.
Dyfed-Powys Police Det Insp Richard Yelland said the sentence recognised "long-lasting harm" to the victim.
He added: "This is the second case for the force, in recent weeks, where a significant custodial sentence has been passed down to a perpetrator of non-recent sexual offending."
