August 10 and 11

Ecological Notes:

  • First sighting of Ollie the sea otter since I arrived. His new favourite location is in the kelp east of Great Race. I had seen him there on a boat trip on Aug 1.
  • First on-land passerines of my stay seen on Thursday, Aug 11: two juvenile Brown-headed Cowbirds. It is possible the bird I saw in the fog last week could have been one of these.
  • Sea lion numbers continue to climb.
  • Whale action must be in the Gulf Islands/San Juans, as fewer whale watching boats are coming this way.
  • Most of the young gulls are busy testing their wings, especially when the wind comes up.
  • Very low tides have revealed the eel grass beds and normally hidden intertidal zone.
  • See photos below for more ecological sightings.
