Campaigners in Dorking, England, are raising alarms after the demolition of part of a building during the swifts' migration season reportedly displaced nesting birds. The demolition, which took place at Station Approach, involved the removal of a wall containing crevices used by swifts for nesting. Photographer Amy Brewer observed swifts trying to return to their nests, expressing concern over their displacement. Julia Hemsley from Dorking Swift Conservation emphasized that swifts are loyal to their nesting sites and warned that losing their nests could prevent them from breeding again. Clarion Housing Group, the developer, stated that ecological checks were conducted before the demolition, but campaigners claim that nests were present. Mole Valley District Council has issued a temporary stop notice and is investigating compliance with wildlife laws. The council's cabinet member for planning noted that while nesting bird checks are required, there is no absolute prohibition on demolition during the nesting season. The situation highlights the tension between development and wildlife conservation in urban areas.
