Changing Fish Diet Killing Baby Birds in Gulf of Maine

”’The birds are a barometer of what’s going on in the Gulf [of Maine]. Something isn’t working,’ he said.

”What that something is is difficult to pinpoint. Benedict is hedging his bets on either climate change or overfishing of herring. Herring need a certain temperature water to live in, he said, and if they need to dive into deeper waters to get that chilly temperature, the shallow-diving terns would not be able to reach them. As for fishing, he said trawling ships can break up schools of herring, dispersing them, also making it more difficult for terns to hunt.”
