The falcons are feeding on a variety of birds

Derbyshire Wildlife Trust are monitoring two peregrine falcons that have been seen perched on the roof of the city's cathedral.

Bird watchers believe the pair have been using the lights of the city centre to help them hunt for prey.

Evidence from the area around the roosting site suggests the falcons are feeding on a diet of the city's ducks, thrushes and pigeons.

Nick Brown from the trust said the falcons are quite rare.

"They have come back strongly recently to traditional sites such as cliffs and quarries in north Derbyshire - but not normally cathedrals.

"To have these birds in the city centre is quite exciting - they seem to use the cathedral like a cliff as it's almost 200 feet tall."

He said the wildlife trust was alerted by the cathedral's architect who saw one of them feeding whilst perched on one of the gargoyles.
