New:

  • A new juvenile male seal was flipper tagged on the South Shore by the Kauai team. The seal’s ID is R1NI.
  • Very pregnant AF R8HE spent two weeks on a North Shore beach. This seal is usually on Maui and Hawaii Island, and pupped on Maui in 2018. She has moved back to Oahu since. Her predicted pupping date was Nov 9.
  • The annual monk seal count day occurred on Oct 19th. Kauai had the most seals with 20 seals reported before noon. Three more seals hauled out later the day for a total of 23 different seals sighted on Kauai that day. The statewide (from Kauai to BI) total count was 50 seals.

Updates:

  • PK6 born at Milolii in September is male, the mother is R400, the same female that has pupped at Milolii in Sept the past 2 years. The pup weaned on approximately Oct 31, resulting in 41-day nursing period. Tour boats and kayak companies are providing updates.
  • S/F R7AA was seen with a small lump under the left jaw line on 8/31/19, it was possibly a small abscess. The seal was re-sighted on 10/21/19 in good health with no obvious abscesses on the jaw line.
  • RH38, the seal rehabbed at KKO and released in July, continues to thrive on the North Shore.
  • All of the 6 pups born this year have been sighted recently and continue to thrive.
  • Displacements: A/F RK13 was displaced from the road edge at Fuji Beach, Kapaa at 3:00 am after calls from the police that the seal was on the road edge and in danger of being run over.
  • Molting: 3 seals molted this month.
  • Vaccinations: No vaccinations given this month.
  • Bleach marking: Two seals were bleach marked this month, both are new untagged seals.

Research/Support of PIFSC:

  • 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.

Kauai’s sixth pup of the year is now a weaner. He was born on September 20, 2019, and his mother, R400, weaned him 41 days later on October 31, 2019. Other 2019 pups nursed  longer; however, this youngster is no lightweight. When he was flipper-tagged last week–as RL40–he measured 124 centimeters in length and 113 centimeters in girth. As you can see in these pictures, he looks nice and plump and healthy. The tagging team reported L40 (L40 left flipper; L41 right flipper) was strong and feisty and didn’t even depart the beach after tagging.

Kauai’s 2019 pupping season began on February 4 and appears to have ended on October 31–unless there is a late-season surprise birth. It’s happened before. In 2009, RK12 gave birth to a pup who was later flipper-tagged as RA36 in late November, the day after Thanksgiving.

Monk Seal Monday #74:

A visit last week to the remote beach where Kauai’s sixth pup of 2019 was born on September 20th revealed two things: PK6 is male, and his mother is, as suspected, R400.

R400 is not flipper-tagged; however, her identification was confirmed from various scars–a line scar on the left side of her face and some small pit scars mid-back. Her most prominent scar is a medium-sized, semi-circular shark bite along her lower back on her right side.

Often, we sight pregnant seals on Kauai who seemingly disappear for four to six weeks, only to reappear looking quite thin. We suspect these seals go to Niihau to pup. However, in this case, R400 does the opposite. She spends most of her time on and around Niihau and comes to Kauai to pup. Therefore, little is known about her. But here’s what we do know:

  • She pupped along Napali Coast on September 11, 2017, and photographs revealed identifying scars. She was logged into NOAA’s ranks as R400. However, R400’s pup was never tagged due to the heavy waves and large swells that roll in for the winter about the time the pup was weaned.
  • On September 15, 2018, tour boat operators reported a female seal with a newborn pup at this same remote Napali beach. Again, due to the pup’s arrival coinciding with the return of the winter season’s swells, the pup was not flipper tagged. This time, no photographs allowed for a confirmed identification of the mother. However, the timing matched what would have been a due date of R400.

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.
