A local tourism operator is concerned about the increasing number of bird carcasses appearing on the shores of eastern Newfoundland.

Various species of dead birds have been found around the Burin and southern Avalon peninsulas, including turrs and gannets. It’s believed they’re falling victim to Avian or bird flu.

Mike Gatherall of Gatherall’s Puffin and Whale Watch says he’s seen many dead birds around the Witless Bay Ecological Reserve, adding the entire ecosystem in that area will feel the effects.

He says the birds are essential for returning many nutrients to the ocean.

Gatherall says in many ways they provide “fertilizer” from their capelin diet in the form of nitrates and phosphates.

He believes the long-term effects of the die-off have yet to be felt.

Meanwhile, chief veterinary officer Beverly Dawe warns that the dead birds can pose a risk to mammals, including cats and dogs.

Scavenger animals including foxes, raccoons and skunks have tested positive for Avian flu in other parts of the continent.

As a result, Dawe says it would be wise to keep dogs on a leash when venturing near the shoreline.

She notes seals around Quebec have also tested positive for Avian flu after resting on rocks contaminated by feces from infected birds.
