At this time of year there are lots of changes in nature to celebrate. Wintering birds like knots and dunlin are a spectacular sight as they arrive along our coasts. The coastal wetland habitats like estuaries, saltmarshes, and mudflats that they rely on are also important for us. They can play a role in reducing coastal erosion and protecting coastal sites from flooding. 📷 Andy Hay (rspb-images.com) #ProtectNature #AutumnNature #Wetland #SaveWildlife #UKBirds
