Third elephant seal born on Middle Rocks

Posted on by

Alex noted in his last log that he had heard another pup out on middle island and was able to see it from the tower. Today we have a clear shot at it from camera 1 . The pup seems quite lively. The unfortunate thing is that every year there has been a pup born out there, the next big storm washes it off, so as far as we know there has never in the past 8 years been a surviving pup from the middle island.  Here’s hoping for no storms for the next few weeks??? not likely..

Nursing successfully

Posted on by

Ecological 

  • Wind 15 knots NE increasing to over 30 knots overnight
  • Just before noon, within 24hrs after birth, I saw the pup take what I believe was its first taste of milk.   There seems to be three key ingredients to successful nursing: motivation, location and suction.  All three have to combine for success, there was a lot of trial and error, and what seems to be frustration, on the way.  Once the pup latched on to the right spot the suction and slurping sounds were clearly audible.  Since nursing has begun, both mother and pup seem less agitated, the pup is taking longer sleeps and the mother is getting more rest.

  • 1 ecotour

Maintenance

  • Ran the derrick and lifted out 2 logs.  With engine warm, I drained the engine oil out of the derrick’s old Lister engine and changed the oil filter.
  • Cleared debris from ramp.

Elephant Seal Birth Videos 3- wide angle

Posted on by

This 3 minute video shows the birth at a wide angle taken on a gopro camera mounted on top of the bunker/desalinator building.  The camera is in a weatherproof housing so the sound is not very good.

At 0:45 the pup is out
At 1:40 Chunk starts climbing over the pathway
And at 2:27 Chunk comes in contact with the pup

Pup and mother vocalizations, Chunk is heard vocalizing out of the frame.  A seagull feasts on the nutrient dense placenta.

The pup is looking to nurse but seems like it hasn’t figured out the mechanics of it yet.

In preparing for the oral presentation that the Friends of Ecological Reserves  will give on January 28 in Burnaby, as an intervenor for the National Energy board Hearings, I have recently updated or graphs on Humpback and Orca sightings by the Ecoguardians at Race Rocks: The posts done by our Ecoguardians tagged for orcas or  humpback whales assisted in this tabulation.
