Not sure why but a large pod of Orca have taken station off the Algarve coast between Sagres and Albufeira over the last couple of weeks.
Changing currents, movement of food
supply, cleaner water
... whatever the reason this is apparently the first time Orca have been seen in these waters in living memory..
Or could it be as simple as the large change in the earths magnetic norm has thrown them off course.
