Gentle Winds and Plentiful Wildlife

Weather:

  • Visibility 15+ NM
  • Sky partly cloudy
  • Wind 5-10 knots N
  • Sea state: Calm

Visitors/Boats:

  • Yesterday Laura and Greg came at low tide to deliver fuel and for Laura to teach her online class.
  • Greg came this morning to deliver a load of fresh water which we pumped into our storage tank with the fire pump and hoses.
  • Today we saw a dive vessel in the reserve but no divers. They were fairly close to the wildlife but the sea lions did not seem particularly bothered.
  • One small pleasure craft hovered just outside of the reserve for the majority of the day. They were too far away to see what they were doing, but usually boats like this are fishing.

Ecological:

  • The small seal pup is still here, but she has become more adventurous over the past week. We have seen her napping on the east side of the island, and beside the decommissioned diesel tank on the west side.
  • The sea lion population continues to grow, and so does the smell! We will need to set up more fencing soon before they begin to take over the island completely.
  • The pair of crows that we have been seeing returned today and spent most of their day at Race Rocks.
  • We have continued to observe bald eagles in the reserve. We enjoy watching them swoop overhead and cause a stir amongst the seagulls.
  • One of the seals that we have been joined by over the past weeks was also spotted here in December (juvenile female V173). We are still waiting to hear from the researchers who tagged her to see if there is anything interesting to learn.
  • The elephant seals activity has been uneventful as they continue to moult. They spend their days napping and lounging on our “lawn” or wiggling down to the jetty to soak in the shallow water (and perhaps relieve the itchiness of all that peeling fur!).
  • At low tide yesterday we spotted many neat creatures in the exposed pool on the east side of Great Race Rock: urchins, anemones, crabs, fishes, chitons, barnacles, and tubeworms!

Corvus caurinus:NorthWestern Crow, Race Rocks Taxonomy

The Norhwestern Crow closely resembles the American crow being black noisy and having forward facing bristles above its nostrils. The nw crow is smaller in size and has a shorter lower caw. It also has a smaller bill, smaller wings and has a greater wing beat rate.They usually inhabit coastal areas such as Race Rocks and are not thought to be birds which migrate. The crow usually forages for food near coast lines and its diet may include dead fish, crab, mussels or clams. In most regions its nest may be located at high elevations or in the branches of Conifer trees. Here at Race Rocks, the closest suitable nesting sites are on Bentinck Island.
