The Adaptations and Response of Organisms to the Abiotic factor of Rainfall

Canada geese are dependant on the availability of fresh water at Race Rocks. During the winter, the higher level rock pools are refreshed by rainfall. There is no other natural source of water on the island. By the time their eggs hatch in June, most of the pools have dried up, so they have to take their young off the island and over to the mainland. They may make it past the eagles….(Photo by PB)

The availability of water for vegetation on Race Rocks has major implications for the species of plants which can survive on the island. Not only do they have to survive dessication from salt spray, but abundant water in the winter months and almost a total lack of water from June to September. One of the best grasses to tolerate these conditions is Fescue. Here you can see it growing on the natural rock outcrops on the island.

Much quieter day workwise today.

The sea lions are taking over! They have knocked the fencing down in several places and once again have cleared the fence posts from the jetty. I am conceding defeat! I know Greg and Richard are planning to redo the fence system this week, so the sea lions can claim victory–for now.

During yesterday’s census, I saw a Glaucous-winged Gull with a seriously broken wing. It looked like an old injury given the condition of the wing. I couldn’t relocate it after viewing it from the tower, but today it was near the solar panels. I managed to catch it and will take it to WildARC when I leave on Monday.

The bird of the day remains unidentified. I flushed a small sparrow twice today, but it went too far for me to get a positive identification. I suspect it is a Savannah Sparrow. I am annoyed I didn’t get a better look as there are very few songbirds here.

The entangled sea lion is still present. Fingers crossed for a rescue soon.

Facility work:

  • Clean the solar panels
  • Clean the west and north windows of the Science Building
  • Took hydrometer readings of the batteries in the generator building.

Weather:

  • Sky: clear and sunny all day
  • Wind: variable 0 – 20 knots
  • Sea: rippled
  • Air temperature: low 13 °C, high 27 °C
  • Seawater temperature at max flood: 10.9 °C

Photos from today:

Western Gull, an uncommon species for Race Rocks, although there are a few who are breeding with Glaucous-winged Gulls on site.
