Resumen de Detective gulls sniff out illegally dumped trash
Meet Sea Gull, private eye. Garbage-loving gulls in Spain fitted with GPS trackers have led researchers to an illegal waste dumping site. Illegal dumping can be hard to spot because the perpetrators are often white-collar criminals who are good at covering their tracks. So Joan Navarro tried an unconventional way of finding these operations. He and colleagues at the Functional Ecology and Evolutionary Center--part of the French National Center for Scientific Research--took 19 yellow-legged gulls and fitted them with solar-powered GPS trackers that transmitted the birds' locations every five minutes.
