One of my first jobs of the season as the EU Life+ Lead Little Tern Warden for east Norfolk is to visit all the potential breeding sites along the coast and consider where the most appropriate nesting habitat is located for the little terns. The coastline will have changed dramatically over the winter months, sands will have shifted, marram will have crept forward and the lovely mix of sand and shingle, so beloved of little terns, may have been buried in the winter storms. Thankfully, there are still plenty of suitable nesting locations and there are already signs on the beach that the new season is about to begin. Some good signs, some not so good. The distinctive prints of a ringed plover signal the arrival of the little terns’ beach-nesting companion. These charming birds are always the first to start nesting and will generally already have a full clutch of eggs on the beach by the time the terns arrive. But ominously there are also signs of an altogether less welcome creature. The tell-tale prints, in a straight line, can only be those of a fox - the little terns’ most dangerous predator.
