Great white pelicans eat fish provided by Israeli farmers at a water reservoir in the Emek Hefer valley north of the Israeli city of Tel Aviv on November 15, 2019. An estimated 50,000 pelicans stop off in Israel during their annual migration from the Balkans to Africa, where they enjoy a mild winter before returning to Europe. They rest and feed for weeks, causing chaos for fish farmers, whose outdoor commercial pools and reservoirs provide rich pickings. Farmers have tried to deter them with loudspeakers, laser beams and by firing blank rounds from rifles. In their desperation, they have come up with another way: offering the birds a free lunch.
