New:

  • Yearling female RKA6 was de-hooked by the Kauai team and immediately released. The hook was a large circle hook with 5 m of heavy monofilament trailing. The seal has fully recovered.

Updates:

  • Adult female RB00 weaned her pup after 54 days of nursing. He was tagged as RL08 in April.
  • RK58 was reared at Ke Kai Ola from August 4, 2018 until released on Feb 13, 2019 after a 3 day soft-release. The seal has remained in the release area, has shown no signs of interest in humans, and is interacting normally with other seals in the area. He also molted this month and lost his satellite tag. He was only 8 months old when he molted, which is unusual as the first molt is usually between 12-16 months of age.
  • Displacements: No seals were displaced from the keiki pool. However, adult female RK90 began hauling out at and spending the nights at a beach that’s considered unsafe due to trucks driving on the beach. Therefore, RK90 was displaced (with the proper NOAA approvals and staff) off the beach at sunset five times, twice along with adult male RK05. RK90 continues to return to this beach several times per week but has begun foraging at night again, eliminating the need for further displacement. Close monitoring of this beach continues.
  • Bleach markings: 3 were applied this month.
  • Molting: 2 seals molted this month.

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.

  • A pup switch occurred for the first time on 7/20/18. RH58’s pup PK5 was forcefully taken by another mother RO28 who left her female pup PK4 alone on the beach. The Kauai team successfully reunited the correct moms with pups later that day. Another pup switch occurred on 8/2/18 when RH58’s pup PK5 was seen with another mother RK28 who had left her male pup PK3. Again, RH58 was alone but searching and calling for her pup. The Kauai team attempted to reunite the correct mothers to pups on 8/3/18. RK28 quickly took her pup PK3 back, however, RH58 rejected her pup and became aggressive toward him. The pup was left on the beach overnight in hopes that RH58 would reunite naturally. On 8/4/18, RH58’s pup PK5 was again found with RO28 at sunrise. RO28’s pup PK4 was nearby and began calling for her mother, who quickly left PK5 and rejoined PK4 without human interference. A final attempt at re-uniting PK5 with his mother RH58 occurred that morning of 8/4/18, however she continued to be aggressive toward the pup. The Kauai team captured PK5 (now permanent ID of RK58) mid-day on 8/4/18 and transported him to Lihue for USCG C130 transport to Ke Kai Ola for rehab.
  • Three seal pups weaned and were flipper tagged in August.
  • New adult male seal R8HD hauled out on Kauai after being flipper tagged on Molokai earlier this year. It was suspected this seal had been previously tagged, so the Kauai team was asked to scan the seal for a PIT tag, without disturbing the seal. A full scan was performed, no PIT tag was detected.

Updates:

  • The first pup of the year, now weanling RK42, was de-hooked by the Kauai team on 7/28/18. A large j-hook with 5’ of 100 lb test monofilament leader with swivel attached was removed from the right side of the seals mouth. The pup has not been resighted since de-hooking.
  • Bleach markings: No bleaches were applied.
  • Morbillivirus vaccinations: The North Shore pups RKA4 and RKA6 were fully vaccinated against morbillivirus.

  • Sub-sampled scat, molt, and tissue plug samples accordingly.

Another girl! Because RK30 gave birth in such a remote location, it wasn’t until a boat dropped off a crew to tag RK30’s pup that the pup’s gender was officially confirmed. Her tags are KA2/KA3, so her permanent ID is RKA2. You might be able to identify her by her natural bleach mark on her head. It’ll be interesting to see, however, whether she retains that identifier as she ages and her coat changes color.

PK4 was also tagged last week. (She was born to RO28.) Her tags are tags KA6/KA7, so her permanent identification is RKA6 .
