New:

  • A second pup was born at a remote beach along Na Pali Coast. The ID of the mother is unknown, but likely the same Niihau female that has pupped on that beach the past two Septembers, R400. Tour boats and kayak companies are providing updates.

Updates:

  • Sub-adult female R7AA was seen with small lump under left jaw line on 8/31/19, possibly a small abscess. The seal has not been re-sighted since. The plan is to closely monitor.
  • RH58 (Rocky) successfully weaned her female pup, PK5. The pup was flipper-tagged and vaccinated and now has an ID of RL58.
  • RK30 successfully weaned her female pup, PK6. The pup was flipper-tagged, and the seal’s ID is now RL30.
  • RH38, the seal rehabbed at Ke Kai Ola and released in July, continues to thrive on the north shore.
  • The first three 2019 pups (RL08, RL52, and RL28) continue to be sighted in good condition at various north and east shore beaches.
  • Displacements: No seals were displaced this month.
  • Molting: Four seals were observed molting this month.
  • Vaccinations: PK4 and PK5 were vaccinated during pup tagging and received booster vaccinations three weeks later.
  • Bleach marking: One seal was bleach marked this month.

Research/Support of Pacific Islands Fisheries Science Center:

  • Sub-sampled scat, molt, and tissue plug samples accordingly.
  • Logged all seal sightings for PIFSC database. Organized photos and reported sightings, molt tallies, survival factors to send to PIFSC.

Monk Seal Monday #68: Meet RL28

After 40 days of nursing, RK28 weaned her pup (a female) early last week. By week’s end, PK4 officially became RL28. (Interesting side note: RL28’s left flipper tag is RL28; however, because there wasn’t an RL29 tag, her right flipper tag is RL33.)

RL28 measured 134.5 centimeters from the tip of her nose to the tip of her small tail. She measured 117 centimeters around (girth), taken just below her fore flippers.

Here are pictures of her looking nice and healthy the day before receiving her flipper tags.

And here are pictures of her enjoying a two-hour swim–where she was witnessed picking up, possibly, a sea cucumber–just prior to receiving her flipper tags.

Meanwhile, mom, RK28, has been spotted at various beaches on the north shore. Beachgoers have reported her, concerned about health and confused about her scars. They think they’re recent wounds. They are not. Several years ago, RK28 turned up with fresh wounds on her back that were determined to be the result of adult male aggression. You’ll find more about this threat to Hawaiian monk seal survival here. RK28’s condition will continue to be monitored, especially in this time right after weaning when it’s important that she recover her weight loss. This photo was taken over the weekend.
