Orcas make 2nd rare appearance in Victoria's Inner Harbour

For the second time in 10 days, transient killer whales have been spotted in Victoria's Inner Harbour.

For marine biologist Anna Hall, the appearances are rare, exciting occurrences but the "why" behind the sightings is a bit of a mystery.

"It's tremendously uncommon," Hall told All Points West host Jason D'Souza about the appearances, the most recent of which happened Sunday.

Hall saidtransient orcas hunt marine mammals like harbour seals and porpoises, both of which can be found in Victoria's Inner Harbour but that doesn't mean they're coming for food.

"These are very complex creatures and there could be other things that have drawn them into the region ...It could have been out of plain curiosity that's driven them in there," Hall said.

She saidthe harbour is much like the inlets and fjords favoured by the whales except the harbour is full of people.
