“We could hear their bellowing from our porch,” says a Franquelin-based collaborator of News from Afield, referring to the cries of three harp seals thirty metres from the coast. Seals use a variety of sounds to communicate: barks, growls, squeals, chirps, etc. They are particularly noisy in the water and during the breeding season. Seals living in the Arctic, such as the harp seal in summer, are believed to be even quieter when they’re out of the water, notably to reduce the risk of attracting polar bears.
