On a cold, miserable morning in May, Stan Gehrt trod across an open field as wind and rain blew in his face. He was leading a team of wildlife biologists on a mission to find an animal with a gift for not being seen.The team didn’t have to travel far from its headquarters for the search. A female coyote had made a den within sight of Chicago’s skyline. They were only “about five kilometers” from America’s busiest airport, O’Hare International, Gehrt said as he advanced toward the den, wind howling through his cellphone microphone during an interview.
