Census July 6

Posted on by

Ecological Notes:

  • I am seeing more gull chicks everyday. Many gull parents are frequently feeding their two or three chicks.
  • I seem to have come to an understanding with some gulls. If I approach near them on the path at a slow speed, we both ignore each other. There are other gulls who freak out if I even look in their direction. As I do necessary work, I limit my movements around the island and avoid certain paths that have nearby nests and chicks.
  • See photo gallery and captions for more details on the ecological happenings over the past two days.

Gull Chicks Everywhere

Posted on by

It is great to be back as the Ecoguardian at Race Rocks. I have been lucky enough to spend a total of almost seven months here between 2014 and my last shift which ended on September 1, 2020. I have been spending the past three and a bit days reacquainting myself with the island and infastructure. I have not stayed here before in July, so it is taking some adjustment to live in harmony and not disturb hundreds of nesting gulls. It drastically limits where I can go on the island.

Ecological Notes:

  • The glaucous-winged gull population is increasing everyday with lots of chicks hatching. I do my best to avoid getting close to the nests. I move quickly by the ones near doors and pathways on which I need to travel to get to the energy building, jetty and lighthouse.
  • A pod of orcas swam westward through the ecological reserve on Saturday, July 2, then went eastward in Race Channel. The orcas continued to head eastward, with at one point 14 ecotour boats viewing them from a safe distance.
  • A juvenile male elephant seal, tagged D018/D019, has been hanging around here for a while this spring and early summer. I noticed the tags this weekend, so I could confirm it was the same seal that Ecoguardian Joan spotted on the seal’s arrival on the island on May 19. Here is a link to the tagged resight histories, when I spotted this seal in April 2020 and reported the details to the Director of the Año Nuevo Reserve, in California. The brief version is he was tagged in February 2017 as a pup in Año Nuevo. He was first observed at Race Rocks in April 2018. He was again spotted here in April 2019, December 2019, and April 2020. His proboscis (nose) and body has grown a lot in the past couple years. I wonder what adventures he has gone on in that time.
  • I know of two black oystercatcher chicks that I have seen through the binoculars and  long lens of the camera. One is hanging out near the jetty with its parents. The other is hanging out near east bay with its parents. The dark grey fluff ball chicks are hard to spot, as they blend in well with rocks.
  • See the photos below for these and more ecological sights.

Weather:

  • The wind has been consistently coming from the west over the past four days that I have been here.
  • Friday and Saturday were part cloudly with lots of sun to fully charge the solar panels by 17:00 both days.
  • Sunday and Monday were overcast with periods of rain and fog.
  • The temperature in the past four days has ranged between 11 to 14 oC.

Visitors:

  • Greg drove the boat on the afternoon of Friday, July 1 to do the shift changeover between Jillian and I. Thanks, Jillian, for leaving the place in such great shape.

Vessel Traffic:

  • Many Canadian and American ecotour boats have been nearby throughout this long weekend.

There were a lot of eco tourism boats passing through the ecological reserve today. An outrigger canoeist paddled through the main channel in the mid morning and again in the early afternoon.

Tomorrow is my last day as the Ecoguardian. Mara and Kai are returning for a few months. I have enjoyed being back on this wonderful island for the past 17 days, learning on the edge where the land meets the sea meets sky. Race Rocks is a unique place that couldn’t exist without the work of Pearson students, staff, faculty, alumni and volunteers.

Here are some sights from around the island today:
