A Big Storm + Lots of Birds! (census)

Posted on by

Weather Today: 

  • Visibility 14 NM
  • Sky partially overcast
  • 30-55 Knots SW
  • Sea state: swells up to 2m, otherwise 3-4+ ft chop

Visitors/Traffic: Nothing other than a few fishing and shipping vessels in the strait.

Ecological Notes: 

  • We found another apparently healthy gull dead today; this is the fourth one since the beginning of the month. We now have two preserved for necropsy, which we hope to transport to land soon to be investigated. They have all displayed the same odd symptoms: weakness in the wings progressing to unable to move, wings dropping to the sides, and unable to make any sound.
  • This week there have been an incredible number of cormorants in the reserve! An underrated bird, they are very fun to watch as they waddle, preen, and fish.
  • We’ve been noticing some fungi popping up around the island now that we are into the rainy season! Photos below. These are in addition to the shaggy mane mushrooms we found last spring fruiting beside the composters.
  • Last week we spotted another “neck wrap”: a california sea lion with some kind of pollution material embedded into his neck. Unfortunately it seems that he is no longer present in the reserve, making a rescue improbable.

Census:

  • 4 black oystercatchers
  • 1 dunlin
  • 1 ruddy turnstone
  • 9 black turnstones
  • 3 surfbirds
  • 500 Thayer’s gulls
  • 17 Canada geese
  • 1550 Cormorants (wow!)
  • 2 bald eagles
  • 100 stellar sea lions
  • 502 California sea lions
  • 2 harbour seals

A Canada Goose Curiosity

Posted on by

Weather Today: 

  • Visibility 10-15 NM
  • Sky overcast
  • Wind 20-30 knots NE
  • Large swells and some whitecaps

Visitors and traffic: 

  •  There has not been many boats coming through, probably due to the poor conditions.

Notes: 

  • The weather since our last post was very rough, we had winds of over 50 knots (about 100km/h) and some very rough surface conditions.
  • We have been having some equipment issues but we are back and have some great photos to share!
  • On Saturday we spotted an oddity – a Canada Goose with a mostly white neck. It really stood out from the rest of its feathered friends and it was a rush to the camera for us. We think it may be leucistic. Leucism is not one specific condition, and this ‘depigmentation’ probably has an underlying genetic cause.
  • We have seen a variety of eagle but most exciting was the bird about 20 feet in front of the house, perched on top of a freshly caught seagull!
  • On Sunday a seagull with a badly injured and nearly missing wing was around, perhaps the result of a predator attack gone badly for both parties. It was completely alert and walking around with the other seagulls but we haven’t seen it since and presumably it succumbed to its injuries or predation.
  • Canadian Coast Guard Ship John Cabot, an offshore fisheries science vessel, paid the area a visit. The vessel hung around for about an hour and looked to be doing something with a lifeboat, maybe training? CCGS John Cabot was just recently constructed at Seaspan Shipyards and was launched in July, champagne bottle and all, by provincial health officer Dr. Bonnie Henry.
  • Visibility has been erratic – we will have a census posted when first possible.

Albinism in The California Sea Cucumber

The Sea Cucumber Parastichopus californicus is normally a reddish-orange to brown color, although there is also a beige color phase with dark brown spots.( leucistic).  In the past year, 2 of these white variants have shown up near Race Rocks
