A pair of young peregrine falcons which have made their home in Bath have been ringed so they can be tracked by conservationists.
The two chicks hatched on the roof of St John's Church, in South Parade, in April, but before they leave their nest local experts have attached identification rings to their legs so their progress can be monitored.
The ringing was done by trainee bird leg ringers Luke Sutton, from the Hawk and Owl Trust, and the South West Peregrines Group, and Hamish Smith, also from the trust and Hawk Conservancy Trust, who regularly monitor the nest box at the Catholic church.
The eggs of two unhatched chicks have also been removed from the nest at the church for forensic analysis by the British Trust for Ornithology.
Peregrines were observed in Bath from 2000 but after three years without successful breeding, the trust built a nest platform at St John's.
The birds were last year filmed for the BBC show Springwatch and have become a regular attraction for local ornithologists.
The Royal Society for the Protection of Birds has in the past set up a viewing station on the River Avon, near Pulteney Weir, to allow passers-by to use a telescope to look at them nesting in the boxes.
