A pair of ravens at the Tower of London have had both their wings clipped to prevent them escaping the historic monument.
Birds at the tourist hotspot often have one wing clipped to help keep them within the building's grounds, but Jubilee and Branwen had both wings clipped to stop them flying to the top of the White Tower.
The measure was taken after the ravens were released from their enclosures following the avian flu epidemic.
Rob Fuller, chief yeoman warder of the Tower of London, said: "The ravens are part of the Tower community and we take our responsibility for their welfare very seriously.
"We regularly consult veterinarians to ensure they get the best possible care.
"The majority of our ravens were bred and raised at the Tower and have not lived in the wild.
"For their safety, we trim one of their wings, to encourage them to stay at the Tower, where we can look after them and feed them a varied diet."
There are traditionally six ravens resident at the tower.
King Charles II is thought to have been the first monarch to insist ravens at the Tower be protected after he was warned the crown and the Tower itself would fall if they left.
Jubilee was presented to Queen Elizabeth II to mark the 2012 Diamond Jubilee and Branwen was born at the fortress in lockdown.
Some ravens have left the tower in the past. One bird flew to Greenwich before being returned by a member of the public after a week while another disappeared after it was last seen outside an East End pub.
