Scientists track longest wolf trek across Europe through its droppings

Researchers have traced the droppings of a German-born grey wolf that traversed three countries to reach northeastern Spain, making it the longest journey ever documented for that species, the Autonomous University of Barcelona (UAB) said on Monday. The male, named GW1909m, travelled at least 1,240 km (770 miles) from his birthplace in Nordhorn, Lower Saxony, crisscrossing France before appearing to settle near a village in the Catalan Pyrenees, where he was last detected in February 2023.
