A significant colony of bank swallows, estimated at around 2,000, faces an uncertain future as plans for the redevelopment of the Byron Gravel Pit, their summer breeding grounds, raise concerns about their habitat. While the development aims to create high-rise residential areas and a public greenspace, the remediation of the steep cliffs where the swallows build their nests may pose a threat. Experts are urging the city council to ensure the preservation of the bank swallow habitat through alternative measures, such as the creation of artificial nesting sites or the identification of a different location within the area.
