What a Windy Weekend! (seagull chicks, census)

Posted on by

Today’s Weather: 

  • Sky partly cloudy (thick fog until late afternoon)
  • Visibility 10 NM (less than 200 m until late afternoon)
  • Wind 30-35 knots W
  • Sea state: swells up to .5 m, whitecaps

Marine Traffic/Visitors: 

  • Not many pleasure crafts this weekend as it was very windy (up to 40 knots!).
  • Greg visited today to deliver supplies
  • More whale watching boats this weekend than we have been seeing, around 5 per day.

Ecological Observations:

  • The seagull chicks have started hatching! Only a few nests have hatched so far. We have observed the chicks asking for food and the parent not feeding them. We wonder if there is enough food available to support them all through this nesting season.
  • One of the first nests to hatch had 3 chicks, but now they are nowhere to be seen. We are observing with an investigative eye as nesting season progresses, as we observed many instances of adult birds cannibalizing each other’s chicks last year.
  • One of the four goslings was eaten by seagulls on Saturday afternoon. The remaining three seem healthy and strong.
  • Not many visiting birds this past few days, perhaps due to the high winds.
  • Many harbour seals hauled out on outcroppings during the notably low tides over the past couple of weeks. The young seal pups are still keeping close to their mothers but we have not seen any still nursing.
  • The oyster catcher chicks are growing at an impressive rate! They seem to be doubling in size almost every week. They are now old enough to venture away from the protection of the rocky areas and explore the intertidal with their parents.

Census: 

  • 2 Male elephant seals moulting
  • 500 Seagulls, handful of chicks
  • 16 Adult geese
  • 3 Goslings
  • 10 Adult black oystercatchers
  • 3 Black oystercatcher chicks
  • 56 Harbour seals

Throughout the week we also observed pigeon guillemots, eagles, and a pair of swallows. The sea lion who was here alone over the past weeks seems to have moved along.

Goslings!

Posted on by

Today’s Weather:

  • Sky blue, obstructed by very thick fog
  • Visibility 200-500 m
  • Wind 5-10 knots SW
  • Sea state: calm

Visitors/Marine Traffic:

  • Today Greg visited to do some maintenance
  • One whale watching boat in the reserve yesterday
  • The occasional pleasure craft outside of the reserve or passing through

Ecological Observations: 

  • No seagull chicks yet, although most nests have 2-3 eggs now.
  • The oystercatcher chicks have grown incredibly fast, and are now approximately half of the size of their parents
  • One male goose who was injured by another goose during a fight earlier in the year is still limping. It seems like the damage to his leg will be permanent and while he is able to move around the island, he sits to eat and is too slow to keep up with the other geese. He spends a lot of time alone.

 

Sunny Monday, Census

Posted on by

Today’s Weather Conditions:

  • Sky clear
  • Visibility 15+ NM
  • Wind 20-25 knots W
  • Sea state: calm, rippled
  • Temperature today

Visitors/Marine Traffic:

  • Today Greg delivered water
  • There was one pleasure craft fishing within the reserve this morning.
  • One whale watching boat today. They came very close to the jetty where there was an elephant seal soaking in the water to relieve his molting discomfort. The elephant seals visibly react to the disturbance with vocalization similar to when they are threatened by other male seals.
  • One large private vessel passed through on Saturday evening with roughly 15 people on board

Ecological Observations:

  • The goslings are doing well and have been moving around the island. The parents seem very alert and keep them close. It is quite impressive given how limited fresh water can be.
  • There have been quite a few young (still have grey plumage) seagulls passing through. They don’t integrate with the other seagulls, but rather stay on the more exposed areas of rock.
  • The nesting seagull population seems to have stabilized, and there are roughly 300 seagulls consistently on the island. When Daniel was here he counted around 80 nests, but there seem to be more appearing daily.

Census:

  • 294 Seagulls
  • 12 Adult black oystercatchers
  • 2 Black oystercatcher chicks
  • 117 Harbour seals
  • 1 Juvenile bald eagle
  • 6 Brandt’s cormorants
  • 59 Pigeon guillemots
  • 2 Male elephant seals
  • 1 Young stellar sea lion
  • 16 Adult Canadian geese
  • 4 Canadian goose goslings

 

Busy Critters

Posted on by

Today’s Weather Conditions: 

  • Sky overcast
  • Visibility 15+ NM
  • Wind 0-5 knots SW
  • Sea state: calm

Visitors/Marine Traffic: 

  • Yesterday Greg and Jake came from the college to deliver some equipment
  • An influx of boats today. We have been seeing 3-5 whale watching boats everyday. They have been coming very close to the elephant seals when they are in the shallow jetty water and also very close to the kelp patch where “ollie” the sea otter likes to rest. Quite a few pleasure crafts as well, and two kayakers this afternoon who explored the intertidal at low tide.

Ecological Observations: 

  • The 4 goslings are now over 1 week old. The parent geese seem much more responsible than the previous, and the goslings seem to be doing okay.
  • There have been nearly no sea lions in the reserve this week.
  • On Friday evening we spotted a sea otter swimming in the kelp around the jetty.
  • Two whimbrels stopped in for a visit on Thursday evening

 

Hatching Goslings + Exciting New Arrival

Posted on by

Today’s Weather Conditions:

  • Sky clear, a few fluffy white clouds on the horizon
  • Visibility 10 NM
  • Wind 20-25 knots W
  • Sea state: fast moving ripples, occasional white caps

Special Feature! Daniel who visited last Thursday has allowed us to share the information that he collected while he was here: Click Here to view his photos and recordings. There are some great shots of the oystercatcher chicks!

Visitors/ Marine Traffic:

  • On Monday Greg delivered water and fuel
  • Yesterday afternoon a large coastguard ship and smaller rib passed through. They looked like they were having a blast taking photos in front of Race Rocks.
  • A handful of whale watching boats in the reserve over the weekend. Interesting to note that they have altered their path and seem to be more interested in the farther outcroppings this season.
  • On Monday a large coastguard helicopter flew overhead

Ecological Observations: 

  • The last remaining goose nest under camera five hatched over the weekend and there are now 4 goslings. While we are hopeful that they will be able to survive, reflecting on the fate of the previous 5 we are doubtful that they will be able to compete and/or evade predators this late into the season.
  • There are now two large elephant seals! Another huge male appeared overnight yesterday. He is enjoying relaxing in the shade next to the guest house.
  • The seagulls have become much more aggressive towards us. Although we are careful to stay on the footpaths and not disturb the nesting birds, they take swooping passes at our heads and drop excrement from above.
  • The seagull behavior towards each other has also become much more territorial. They fight over nesting materials, food, and to maintain their nesting locations. The female seagulls stay near the nesting site, while the male seagulls fish or scavenge for food. The male seagulls regurgitate food for the female seagulls, much like the adults regurgitate food for their chicks.

Other Notes: There has been ammunition detonation on the department of defense land across the water today and yesterday. The location they are using is very close, and with every blast the geese and other birds startle and scramble for a few seconds before settling down again.

Biodiversity Aplenty + Sunday Census

Posted on by

Weather:

  • Sky overcast
  • Visibility 15+ NM
  • Wind 20-25 knots W
  • Sea state: chop, whitecaps breaking at .5 m

Visitors/Marine Traffic:

  • On Thursday an electrician came to work and Greg brought us some supplies- Thanks Greg!
  • Also on Thursday, Daniel came to do a bird count and take recordings of bird calls. He was able to spot and identify many more species than we are able to, and it was fantastic to learn more about what is here! He also found owl pellets near where we heard an owl in April, and we are excited to see what information can be concluded from them.
  • On Friday Greg delivered water
  • Also on Friday, there were many RCMP boats just outside of the reserve.
  • There have been a few pleasure crafts, some fishing within the reserve boundaries.
  • One whale watching vessel today, which approached the animals and the jetty very closely

Ecological: 

  • Daniel also spotted two new observations: a fern growing out of a crack on the lighthouse, and some beautiful harvest brodiaea.
  • There is now only one elephant seal, the large male.
  • There is one goose still sitting on a nest underneath camera 5. She’s been there for a long time and we are wondering if the eggs will still hatch since it is so late in the season. There are no goslings currently, but still a constant 16 adult geese total.
  • In the past two weeks we have been observing many jellyfish in the water, including sea nettles, fried egg jellyfish, and the occasional water jelly still.
  • On Thursday morning we watched as two eagles chased one seagull into the water and continuously took turns diving at it. They dove at it until it was completely wet and unable to fly away. At this point, one of the eagles swooped down and carried the seagull away by its neck.

Census: 

  • 280 Seagulls
  • 12 Adult oystercatchers
  • 2 Oystercatcher chicks
  • 157 Harbor seals
  • 1 Adult male elephant seal
  • 16 Adult Canada geese
  • 11 California sealions
  • 3 Stellar sealions
  • 9 Pigeon Guillemots
  • 2 Adult bald eagles
  • 1 Barn swallow

Glaucous-winged gulls nest

Posted on by

Weather: 

  • Sky partly cloudy (intermittent fog)
  • Visibility 15+ NM (less than 400 m this morning)
  • Wind 15-20 knots W
  • Sea state: calm, rippled

Marine Traffic: A few eco-tourism vessels over the past few days. One approached extremely close to the sea lions today.

Ecological: 

  • The five goslings seem to have been eaten by another animal, perhaps eagles. We have not been able to spot them in two days, since we had a very stormy night. We found one gosling deceased near our back steps following the overnight storm. It appeared that it had become separated and could not survive the elements alone.

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

Beautiful Spring Day

Posted on by

Weather: 

  • Sky partly cloudy
  • Visibility 15+ NM
  • Wind 10-15 knots SW
  • Sea state: calm, rippled

Visitors/Marine Traffic: One pleasure craft within the reserve yesterday

Ecological: 

  • There are now 5 goslings between 2 nests
  • There are 2 oyster catcher chicks (nest on E side of island). They are too elusive for our camera for now!
  • The garbage brought to the island by seagulls is increasing now that they are nesting and laying eggs
  • Yesterday we spotted a patch of broken seagull eggshells near the guest house. Our best guess: the gulls are already looting neighboring nests for food
