Cranes form lifelong pair bonds and are very site loyal. The pair that nested at Willow Tree Fen were expected to return from their wintering grounds in February but arrived on Friday 22 January. Lincolnshire Wildlife Trust therefore closed the site with immediate effect. Cranes need peace and quiet, and to be socially distanced from people and dogs. Closing the site will give the cranes the best possible chance to nest in Lincolnshire for a second time.
Once the birds have settled in, a Watch Point will be set up at the entrance to the reserve to allow people to see the birds from a safe distance. A team of Crane Watch volunteers will be on hand to watch over the birds and help answer questions.
