Four peregrine falcon chicks who hatched in one of Salisbury Cathedral's towers have been ringed less than a month after their birth.
The blue rings - added to their feet - will allow ornithologists to monitor the three females and one male South West region peregrines.
The RSPB say the birds of prey weighed in between 25oz and 32oz (700-900 grams). They are expected to grow their feathers later this month and they'll then spend around a month at the cathedral learning how to be independent before going their own way.
Cathedral bosses say they have now launched Peregrine Tower Tours so visitors can learn more about the cathedral's latest additions.
