Otter, Caspian Terns, Goslings (!) & Sunday Census

Posted on by

Weather:

  • Sky clear, a few clouds
  • Visibility 15+ NM
  • Wind: 30-35 knots W
  • Sea state: fast moving, white caps breaking at .5 m

Visitors:

  • Greg visited with a water delivery on Friday
  • One eco-tourism boat in the reserve yesterday evening.
  • One vessel fishing within the reserve on Friday afternoon. They approached the sea lions around the jetty very closely and their dog on board barked loudly at the animals. They approached the animals within a stones throw and hovered for roughly 20 minutes. The animals appeared distressed and fought with each other as they tried to move away from the boat (it was too close for them to enter the water).

Ecological: 

  • On Thursday evening a river otter came onto land near the jetty. We wonder if it was trying to steal seagull eggs.
  • On Friday afternoon two caspian terns flew overhead. The seagulls were not happy to see them and chased them out of the reserve.
  • Related to the post linked above, we spotted an oyster catcher nest on the west side of the island. We think it could be the same one that Mike spotted in 2012!
  • There are five goslings total, one family with two and one with three. The family of three has been joined intermittently by the other two. The two chicks seem confused as to which geese are their parents, and they’ve even managed to sneak under a wing with the rest for shelter. The parents continuously try to separate them from their own three chicks and the parents of the two follow closely behind.
  • We have observed the geese moving around the island trying to find fresh water. When it rains it is easier for them to come near the structures and drink the water from our roofs. When it is dry, they are limited to what they are able to find in the pools high on the rocks, usually full of algae and very dirty. We have been learning about their adaptations to drink salt water here.
  • The two oyster catcher chicks that we spotted earlier in the week have maintained their elusive nature. We haven’t been able to spot them again, as they are hidden by their parents among rocks where the seagulls are not able to attack.
  • This week has brought an influx of stellar sea lions, particularly smaller youngsters.

Census:

  • 2 Elephant seals (1 male, 1 female)
  • 46 Harbour seals
  • 326 Seagulls
  • 10 Stellar sea lions
  • 17 California sea lions
  • 10 Black Oystercatchers(adult)
  • 2 Oystercatcher chicks
  • 16 Canada Geese (adult)
  • 5 Goslings
  • 2 Pigeon Guillemots

Clear. Westerlies all day with speed averaging around 20 knots.

1 tour boat

3 cargo ships passed through the strait throughout the day

1 helicopter passed over the reserve at 1300h

Business as usual on the reserve today:

-Another female elephant seal has arrived, bringing the current count to 5
-A California sea lion was hanging out on one of the south islands
-The pair of Caspian terns was back again today

Caspian Terns

Clear skies. Light variable winds. Force 1-2. The barometer has been on the rise today. Although the forecast for today called from strong West winds, the barometer does not lie, and it was a lovely calm day. The forecast for tomorrow is for the usual strong West winds in the afternoon. 1 tour boat I saw two Caspian Terns (Hydroprogne caspia) today. They briefly flew over the island in the morning, and then came back in the late afternoon while I was washing my dive gear. They stayed up pretty high, coming maybe as low as the top of the tower, and are really hard to photograph. But their loud croak and dark heads gave them away. I also saw a Heermans Gull (Larus heermanni ) while I was taking my dive kit apart. It’s the first one I’ve seen, but as far as gulls go, it is one of the easiest species to identify because of it’s dusky grey colour. According to the Cornell Bird lab, the Heermans Gull is “unmistakable; [it is the] only North American gull with a sooty gray body and a white head.” Erik came out today at low slack and we went for a dive. We cleaned the camera, checked some camera connections, and cleared the path through the kelp to the jetty. Ok visibility, but it is always awesome to get underwater.

Things have been fairly quite lately regarding birds and mammals here, though one of the eco-tour boats reported seeing a Sea Otter (Enhydra lutris) in a kelp bed on Monday! The percussive blasts from Rocky Point military testing range scared off most of the Sea Lions last Thursday and only a few have returned in the last couple days. A large pod of orca passed through and near the reserve on Tuesday. Thanks to Suna, Doris and Ishmael for the census.

Caspian Terns

Caspian Tern, June 11, 2012

I have noticed several (2-6) Caspian Terns (Hydroprogne caspia) in the area for a month or so. They have proven very challenging to photograph but I got a couple good shots this afternoon. It is the world’s largest tern with a length of 48–56 cm, a wingspan of 127–140 cm. The global population is about 50,000 pairs. They have a distinguishing croak that sounds a bit like a Great Blue Heron.

I also finally found an Oystercatcher nest just above the high-tide line on the West side of the island below the engine room.

Mike Robinson, the Lester Pearson College Ecoguardian at Race Rocks Ecological Reserve, reported in the Race Rocks log on Caspian Terns and provided this picture.
This is the first image taken of this species at Race Rocks June 10, 2012.

Busy Times

Posted on by

A lot is going on in and around the reserve. I spotted 6 Caspian Terns in area over the last week. Twice orca have gone past, though at the northern boundary, well-observed by tourists on the excursion vessels that are now very frequent visitors. There is a River Otter now living under walkway in front. 

This morning 9 Elephant Seals were present, a new record! At least to me… They include Numbers 6355, 6360, 6397, 5086, Bertha, Noah – young male 3-4 yo est.), 2 untagged 2-3 yo juveniles, AND, happily the sad seal with the infected mouth that suffered for weeks on the end of the pier returned, and she is looking great! I had observed that after one of the sharp pieces of jaw bone that was protruding from her lower palate fell out she quickly returned to the water to find sustenance; she was very skinny and weak at the time.  Although her mouth is still repairing and healing itself it is clear she was able to feed well and she must have gained 40 kgs in fat in 5 weeks. I am astounded and impressed with the recuperative powers of these magnificent creatures.
