“It All Started With a Few Trout. Now Yellowstone’s Iconic Birds Face ‘Collapse.'”

“DOUG SMITH DOESN’T remember the moment he realized that a serious ecological crisis was under way in Yellowstone National Park. But as more and more birds began to dwindle, what appeared before him was, he says, “an expanding picture of avian collapse.” One of the first signs Smith spotted presented itself on the normally tranquil Riddle Lake in 2014. There, floating upside down, was a young trumpeter swan killed by a bald eagle. The cygnet was the last of an entire clutch of five siblings eaten by the mighty white-crowned raptors, an act that in one fell swoop wiped out all of the park’s newborn swans for the year.”
