Hamza Yassin and Charlotte Smith are on the beautiful Northumberland Coast. Hamza travels to Coquet Island with the RSPB's site manager, warden and volunteers to help restore a nesting platform for the very rare roseate tern, repairing the damage caused to it by burrowing puffins. Hamza also embarks on a wildlife safari at Lindisfarne National Nature Reserve as he attempts to spot some of the magnificent birds that flock to the area over the winter months. Charlotte meets Kuki the biosecurity dog, who is tasked with seeking out pests that could have a devastating effect on precious seabird colonies. We also meet community volunteers from the coastal village of Alnmouth who are restoring their three-acre pond into a haven for wildlife. In the Cotswolds, Adam harvests apples to make into juice.
