John Underwood has always been fascinated by tufted puffins. For more than 60 years, he’s been visiting Cannon Beach to watch the charismatic seabirds swoop and waddle around Haystack Rock. The stocky birds are easily recognized: solid black with a white mask, long yellow plumes running down the back of their head, and a large, triangular orange bill, a combination that resembles some crossbreed between punk rocker and clown. But over the past decade or so, he says, Underwood started seeing fewer and fewer of them during his regular visits.
