– AP: Marine birds disappearing in Pacific Northwest — Significant ecological shift, crashes in many species — “Something’s happening on a big level, but what is it” — Herring problem may be far worse than revealed… result of contamination?

Seattle Times (AP), Craig Welch, July 24, 2014: Once-common marine birds disappearing from our coast […] a significant ecological shift in our region — a major decline in once-abundant marine birds. […] the number of everyday marine birds here has plummeted dramatically in recent decades. […] several new studies now also link many dwindling marine bird populations to what they eat — especially herring, anchovies, sand lance […] Some forage-fish species, such as herring, are a fraction of what they once were. […] There’s certainly no shortage of crashes […] “It’s one thing to have a rare species decline,” said Joe Gaydos, with the SeaDoc Society. “[…] We’re talking about big, common species, and a lot of them.” […] it wasn’t clear whether this was a local or continental- scale problem, said Scott Wilson, a biologist with Environment Canada. It’s both: Up and down the West Coast, the winter breeding population [of Western grebes] is half what it was in 1975. […] since 1970 [Puget Sound’s biggest] herring stock has crashed, with more than 90?percent of the population all but gone. […] some scientists believe the herring problem itself may be far worse than others acknowledge. […] Wayne Landis, at Western Washington University […] found that while Puget Sound herring used to live eight to 10 years, they now survive only to age 3 or 4. […] “They don’t get old anymore,” he said. That could be the result of disease or toxic contamination or other changes […] Usually after a bust, herring eventually recolonize, Landis said. The question now: Is this bust different […] “Something’s happening on a big level,” [Gaydos] said. “But what is it?”
