NCF sent me these photos, sent to her from a friend back home. They were taken around Bonavista Bay, Newfoundland. Click to enlarge.
I didn't find any stories online about this incident, but it is mentioned in a CBC story about another polar bear sighting in Central Newfoundland:
Conservation officers caught two polar bears over the weekend — one in Cape Freels near Lumsden, the other in Bonaventure on the Bonavista peninsula.
Rebecca Jeffery, a wildlife biologist with the Newfoundland and Labrador government, said at the end of March that while sightings of polar bears may be up, that doesn't mean there are more; they might just be moving in areas where they are more likely to be seen.
