Bruce’s company sponsors, maintains, refurbishes and cleans the cameras that face both into the nest and outwards.
He said this year’s births were the most successful since the cameras were installed in 2023. Last year, four eggs were laid but only two birds made it to adulthood.
Birds have made the spire their home since a nesting box was fitted to the 13th Century building in 2015.
This year’s young residents – Eurus, Boreas, Zephyrus and Notus, named after the Greek deities of the winds – are now about two months old.
“They’ve followed a perfect plan, they’ve hatched beautifully, they’ve grown beautifully [and] they’ve now been ringed as well,” Bruce said.
