Jon Huckle, who runs an ecological consultancy on the Suffolk-Norfolk border, said any works “would need to be delayed” until the birds had finished nesting.
Due to their protected status, he said it would also need to be established that their young were no longer dependent on the nest, before the project started.
“Some birds leave the nest quickly, but others such as peregrines are more dependent on that nest site, and so the nest may be used for several weeks after the young falcons have first flown, staying near the nest to be fed by the parents,” he said.
“It doesn’t necessarily mean they will need to stop the demolition, but they will have to have proof that the nest had been abandoned before starting work.”
