    This is the best summary I could come up with:


    The volunteers who rescue Atlantic puffin chicks — called “pufflings” — knew something was wrong when so few strays from the Witless Bay Ecological Reserve on Newfoundland’s Avalon Peninsula showed up this summer.

    After searching a sampling of nests on the ecological reserve where Atlantic puffins congregate to breed each spring, Wilhelm and her colleagues discovered that many chicks had perished.

    Adult puffins dive for food such as capelin, a forage fish that can make up as much as 50 per cent of their diet, and bring it back to the nest, a burrow in the cliffs.

    Warmer ocean temperatures also work against Atlantic puffins, who can dive to a depth of only 50 metres to catch capelin and other forage fish such as sandlance and herring.

    In the 2023 season, capelin sold for an average of 16 cents a pound, netting $4.5 million to fishermen in landed value, making it one of the least lucrative fisheries in the province.

    Like the Atlantic puffin, the Leach’s storm petrel is also affected by a growing amount of artificial light from communities, boats and offshore oil installations.
