Boxing Day Megafauna Census

Posted on by

Wind: 0-25 knots NE
Sea State: up to 1 m chop
Visibility: 15 NM
Sky: overcast with sunny patches throughout the days
Temperature: between 6 to 7 C
Atmospheric CO2: 412.28 ppm (recorded by NOAA at Mauna Loa Observatory, Hawaii)

This morning, I heard a ruckus outside the west side of the house, where the a few of the elephant seals have been hanging out. The largest male appeared to be fighting the small juvenile male, while the female watched. The adult was slamming its head down onto the juvenile and biting it. This lasted for a few minutes before the juvenile and female fled to the north side of the path.

While I was doing the census in the middle of the day, there were three people snorkelling off the southwest of Great Race Rock Island. They took turns snorkelling in pairs, while one person stayed in the boat. Six other pleasure craft and eco tour boats were seen in the reserve over the past two days.

Sea Otter Seen

Posted on by

The morning weather went from still and overcast at dawn, to clear with a light west wind that brought the fog in for a few hours, then cleared to sunshine for midday. By sunset a high overcast had developed with high altitude clouds piling up on distant mountains and on the horizon at sea. The barometer continued to climb today and reached over 1016hPA.

Wind direction swung around a few times then settled on a blow from the west rising at times to 28 knots. A gale warning forecasts strengths up to 35 knots this evening. Sunday has a 70% chance of showers and the wind is expected to drop overnight to light winds by the afternoon.

Seven whale watching and one tour/party boat were observed working in the Ecological Reserve today. One vessel, Fantasea VI a party boat cum tour boat, according to the sign affixed to it, spent an hour in the Ecological Reserve feeding many, many loaves of bread to the gulls. They were still flinging bread out as they returned towards Victoria. BC Parks act as stewards of protected areas including BC’s Ecological Reserves and they note that feeding wildlife is illegal.

We found the killing ground for Pigeon Guillemots today with the remains of six adults in breeding plumage found near their nesting area. All of them had the neck skin inside out over the head and were the handy-work of the same predator that is feeding on juvenile gulls this week. This might explain the lack of nesting activity by Pigeon Guillemots. I will investigate further to see how many more corpses there are in the greater area.

Chores were routine maintenance and fighting entropy today.

ANIMAL CENSUS

Posted on by

July 9th Thursday: Animal census

The fog was still there pretty thick but around 11:30 it cleared up and we could go up the tower to do the census. We had a west wind and the forecast was a gale warning for the end of the afternoon.The wind at noon was from West at 24 knots and could go to 35 in the late afternoon. We saw a few Whale watchers boats around noon and we had no visitors. Water is getting colder under 12 degrees Celsius. Guy put a new VHF on the whaler.

The estimation of the population is:
Elephant seals: 3
Sea Lions: 180
Pigeon–guillemots: 80
Gulls: 450 (yesterday we could see a group of gulls with black winged maybe some west gulls)
Pelagic cormorants: 3
Geese: 11 (Today the smallest one of the family of 5 was not in the water swimming but looked lost alone in the island hanging around). They spend more and more time in the water.
Black oystercatchers :0

Bald eagle: 1 (they attack the colony almost every day once in the morning)
