On the afternoon of April 23, Sylvia and I went for a walk in the Trent Wildlife Sanctuary. When up on the drumlin, where the Tree Swallow boxes are, we met two young women birders who said they had just seen what they thought was a Northern Mockingbird. Almost on command the bird appeared and flew away from us. My first for the County. Who said the Wildlife Sanctuary never had any interesting birds! That semi-open area is perfect mockingbird habitat, and I’ll be checking to see if it stays around. Jim Cashmore, Peterborough
