One of the four peregrine falcon chicks that hatched on the spire of Norwich Cathedral has died.
Over a million people have watched the chicks since they were born in May thanks to a webcam set up by the Hawk and Owl Trust.
The body of the chick named Eleanor was found on the church roof.
The trust say the three other falcon chicks named Nelson, Edith and Perry now all sit together on the tower.
The 60th anniversary of the Coronation of Queen Elizabeth II is being celebrated in a special service at Norwich Cathedral today at 3.30pm.
The event marks sixty years since Queen Elizabeth's coronation ceremony in Westminster Abbey on 2 June 1953, 18 months after she succeeded her father King George VI as monarch.
Three weeks after the first one hatched, the peregrine falcon chicks atop the spire of Norwich cathedral are growing fast.
According to the Hawk and Owl Trust, the four chicks are now sporting their first feathers among their down. Their parents are also leaving them for longer periods.
The British Trust for Ornithology is hoping to ring the chicks this week to gleam vital scientific information about the life of the birds once they leave their roof-top perch.
The peregrine falcon chicks on the spire of Norwich Cathedral have been fitted with identification rings.
Metal and plastic rings have been attached to the legs of the chicks by volunteers at the Hawk and Owl Trust and the North West Norfolk Ringing Group.
The volunteers say the rings are harmless and help to monitor the population and distribution of peregrines within the UK.
Each chick has a metal ring with its own unique identification number.
The female chick is already much bigger than her brothers and will be a third bigger than them once they are all fully grown.
A fourth egg did not hatch and has been removed from the platform - it will be sent for analysis.
The young peregrines will be taking their first flights in two to three weeks time.
One of the peregrine falcons nesting on the spire of Norwich Cathedral has laid an egg.
The birds became internet stars after a webcam was installed by the Hawk and Owl Trust in 2011, allowing viewers to watch their every move.
Staff from the charity are hoping for a succesful breeding season after the eggs laid last year didn't hatch.
