When a Baby Orca Visited Central Oregon Coast River | Video Published 04/03/21 at 6:55 PM PDT By Oregon Coast Beach Connection staff (Florence, Oregon) – It’s spring of 2015, a lovely set of days in May. Lisa Horn of Sweet Home is visiting the central Oregon coast town of Florence, during a week where there have been lots of Killer Whale sightings farther up north, especially around Depoe Bay. (Photo above: Seaside Aquarium's Tiffany Boothe spotted a trio of Orcas near Florence about 2010.). Every spring, usually in late March or April, a rather mysterious group of killer whales show up along the Oregon coast, sticking around through May and sometimes into June. They are called transient whales, and not much is known about them. These whales are slightly more beaked in appearance and are a bit of a puzzle because scientists don't actually know where they come from.
