Animal Census April14

Posted on by

by Eco-guardians Allen ilka Olsen MONDAY 15 April
Still windy. What a difference a day makes! At 7.15 only a single sealion on jetty (mature male
Cal); only 11 sealions on rocks near jetty/nine relocated to Middle Rocks. The ‘Two Sisters’
moulting Elephant seals separate but reunited and tucked into vegetation for wind protection.
Single moulting Elephant seal inactive most of day. The seal reported by Joan last week to Van
Aquarium not seen again.
Lots of freighter traffic—7 at once. Now watching for HMCS Max Bernays, new arctic patrol
vessel, to arrive at Esquimalt @1030. Failed to see its arrival, however a navy frigate was
observed. As well, US Coast Guard. Only one private vessel came in the turbulent seas.
Maximum flood today extremely dramatic with standing waves.

Cormorants and guillemots feeding in north water. Immature eagle on rocks next to jetty
keeping 50 guillemots from favourite, sunny east-facing perch. 20 Oystercatcher on seal rock
this morning; 10 surfbird; 6 Harlequin
Spent windy day (41 W/62 gusts) observing animal behaviour (and later in week):
1. Sealion— 18 mostly Cals have remained on rocks near jetty. 25 mostly Stellers have
relocated to Middle Rocks. On Saturday observed 18-20 sealions in water west & near
South Islands all day simply floating; occasionally one would swim staying nearby. They
remained there until dark but were gone Sunday morning. Observed this behaviour with
8 on Wed; group would occasionally go into herding mode.
2. Elephant seal—Moulting large females (?) very attached to each other; one observed
grooming/rubbing itself on the one less advanced in its moult. One quite vocal when
separated from the other. Youngster stays completely away from The Sisters (so
named by Joan).
3. Stellers roar; Cals bark; E seals honk/snore/growl/trumpet (played poorly).
4. Oystercatcher—single bathing in inter-tidal pool.
5. Surfbird—10 bathing in inter-tidal pool.
6. Eagles—three immature perched shoulder to shoulder on Turbine Rock; three more
immatures shoulder to shoulder on West Rock. Odd behaviour. A single elsewhere.
7. Cormorants leave the Rock each evening to roost (on DND land?) and return in droves in
early morning.

Wednesday Census

I am writing this on Thursday although the census was done yesterday.

I was happy to welcome 3 new elephant seals to the island. Yesterday the count was at 5 and from what I can discern there are 2 large female, one subadult female, 1 small female and 1 small male. The small male is tagged. Update next post when I can get the number on its green tag.

Race Rocks Gull Survey April 3 2024
Andrew Jacobs  5 April 2024 at 21:35
Hello everyone here’s our survey results from this week out at Race Rocks.
Thanks to everyone for setting this up and Greg for getting us out there for the survey.
Checklist with photos here.
RPBO / BC Nature Gull survey.
Survey conducted by Andrew Jacobs and James Kennerley.
Survey conducted from Great Race Rock while tides allowed.Surveying adults setting up territory for the breeding season and lingering migrants.
Colour morphs for the resident population of Western x Glaucous-winged hybrids setting up territories recorded. Only one pair was displaying at this time although there were multiple probable pairs present in the area. The Western Gulls were not obviously paired up at this time. One of the Glaucous-winged Gulls was likely paired with a light morph Western x Glaucous-winged hybrid.
The gulls on the high cliff and grassy areas tended to be more positioned as if on territories and the gulls on the lower rocks formed more standard congregation flocks. The adult gulls are in breeding plumage at this date.

Other species
At this time a small number of shorebirds are foraging around the timelines and the Black Oystercatchers appear to not currently be on territory. The Rock Sandpipers and Dunlin are going into breeding plumage. Pigeon Guillemot were absent from the site at this time. Two active Canada Goose nests were present. Only 3 Brandt’s Cormorants were spotted as offshore birds however with time restraints we focused on nearshore surveying.

Western x Glaucous-winged Gull Hybrid (Olympic Gull) Colour Morph abundance results of 215 individuals.
202 adults 13 immatures, light morph (Glaucous-winged trending hybrids) 132 adults and 7 immatures, intermediate morph (Intermediate trending hybrids) 58 adults and 2 immatures, dark morph (Western trending hybrids) 12 adults and 4 immatures. There was a pair of intermediate trending birds courting with synchronized dance displays. One Western-trending adult had a very Western-trending voice.
Avian Species List:
7 Canada Goose
19 Harlequin Duck
4 Black Oystercatcher
17 Black Turnstone
13 Surfbird
5 Dunlin
3 Rock Sandpiper
5 Short-billed Gull (1 immature 4 adults)
3 Western Gull (1 immature 2 adults)
6 California Gull (1 immature 5 adults)

The Weekly Animal Census

Posted on by

Today, it was time for the weekly animal census on Race Rocks – a longstanding tradition (see the full archive, here) that allows us to keep track of an ever-fluctuating population of birds and marine mammals. The morning weather wasn’t particularly promising, with wind, rain, and dark overcast skies.

Combined with high tides and a rough sea state, perhaps it wasn’t entirely surprising that the numbers seemed a bit lower than usual – with the harbour seals in particular mostly hiding out in the waves surrounding the South Rocks, and thus rather tricky to count. Alas – who was about?

Census equipment – species list, binoculars, and a clicker to keep track of everyone

 

March 27th Animal Census

Birds:

Oyster catcher: 22
Harlequin duck: 15
Gulls: 195
Cormorant: 73
Pigeon guillemot: 101
Juvenile eagle: 1
Adult eagle: 1
Canadian geese: 9
Shore / Surf birds: 15
Turnstones: 10

Marine Mammals:

Steller sea lions: 14
Harbour seal: 21
Male Elephant seal: 1 (back on land after a lengthy morning expedition)
Female elephant seal : 0
California sea lion: 24

The weather did eventually start to calm down a bit – still hopeful to catch my first RR sunset of the trip later tonight!

 

Facility Work:

  • Weekly Animal Census
  • Continued algae clean-up on Generator Roof
  • Chopped Firewood
  • Prepared new Water Filters for both the Keeper’s Residence and the Marine Science Building
  • Early AM generator run to top up batteries, PM solar enough to reach charge status of 100%

Noted Vessel Traffic:

  • 1 ecotourism vessel, passing between the South Islands and Rosedale Reef

The great weather had to come to an end eventually! Despite being a dark and cloudy day we lucked out with no rain and no wind.

I had 9 extra helpers for the animal census today, the Pearson students are extra observant so this may be the most accurate count yet!

No sea otters were seen today but the two new ones have been around the past few days. Still no additional elephant seals on the main island, just our solo male! A couple of females have been hauled out on the various surrounding rocks but none of come ashore here.

Kendra – New Ecoguardian!

Posted on by

Hello blog readers! My name is Kendra, and I am the new Ecoguardian here on Race Rocks, so I thought I’d introduce myself.

I grew up in Tsawwassen, BC and have been in love with the ocean and all its creatures for as long as I can remember.

My background is in veterinary medicine, and I’ve been a Registered Veterinary Technician for 8 years now. Much of the work I’ve done in the veterinary field has been marine related. It all started back in 2017 when I worked in sea turtle rescue and rehabilitation in Australia and got my advanced diving license. Shortly after that I returned home to Vancouver where I worked in marine mammal rescue with the Vancouver Aquarium for 4 years, and absolutely fell in love with harbour seals – who remain my favourite animal!

For the past 1.5 years I’ve worked for Fisheries and Oceans Canada supporting Southern Resident killer whale recovery before moving into a marine mammal rescue and response role which brought me all over the BC coast.

Marine mammals are my passion and I’m so lucky to be living here on Race Rocks, fully surrounded by them. I must admit that I am not as familiar with birds, but I am quickly learning as each day goes by here and I’m enjoying watching all of the different behaviours and mating rituals.
