Conservationists in Kielder Water & Forest Park have hailed the incredible success of an osprey love match.
Forestry England experts have now visited the nest of a prolific feathered couple to ring four more of their magnificent chicks.
The duo - known as Mr and Mrs YA - began breeding together in 2013 when they had their first offspring on a specially built platform in the 62,000-hectare (155,000-acre) Northumberland woodland.
Since then 22 of their chicks have successfully fledged and this year’s brood should see them hit the quarter of a century mark.
Joanna Dailey, from the Kielder Osprey project, says:
“Their impact on our growing osprey population has been tremendous. Ospreys are pretty faithful to each other and these two are the perfect match. He’s an excellent hunter and brings back plenty of fish feed the family. She is just as effective as a mother, making sure each chick gets a share and keeping them warm. They are always one of the earliest couples back from their wintering grounds in Africa. Not surprisingly we've become very attached to them."
