I have two videos for you from opposite ends of Canada. First one is from here in BC, more specifically, the west coast of Vancouver Island at Mussel Beach, in Ucuelet.
The title is misleading; the Orcas were actually training the young to hunt sea lions. Wild Orcas are not known for hunting humans.
A bit of trivia...though called Killer Whales, Orcas actually belong to the Dolphin family.
The second video was filmed in Antigonish in Nova Scotia. A mother and fawn are stranded in the ice, the mother can’t get up. When help arrives, the fawn heads for shore.
I love what this pilot did.:) Mother and fawn were seen together later and both appeared to be alright.
