The Kauai team logged 303 seal sightings this month (294 in Mar, 249 in Feb, 252 in Jan, 239 in Dec, 243 in Nov). This included 46 individually identified seals.
New:
· Second Kauai pup of the year was born this past month. Mother is Kauai born RH92, who has become an Oahu seal, even giving birth on Oahu last year. She surprised us by returning to her birth beach this year and giving birth to PK2. The pup is thriving.
· Juvenile Niihau seal was flipper-tagged as R7AJ on the beach at PMRF, and further trained the PMRF.
Updates:
· Adult female RKA2 found logging for 5 days at Aliomanu Beach the previous month. We closely monitored and assessed with a pole camera. Head swollen with bite marks on head, neck, and flippers. Suspect dog attack. Successfully administered antibiotics while the seal was logging in the water. Administered a second dose along with pain meds while the seal was hauled out 6 days later. Seal appeared to be recovering. UPDATE: Finally resighted her fully healed and in good health after 5 weeks with no sightings (since the second antibiotic injection).
· RF30 and PK1, she pup weaned the pup after 39 days of nursing and has remained in natal area. Seal was tagged as RS30, 2 weeks after weaning, somewhate small ax girth of 98 cm, but very healthy and strong.
Program:
· Keoki’s Paradise restaurant hosted a volunteer appreciation luncheon in Poipu and 35 volunteers attended and enjoyed a free lunch buffet prepared just for them. It was part of volunteer appreciation month and a nice gesture by Keoki’s Paradise.
RF30 weaned PK1 at 39 days on April 27th. A week later, he was bleach-marked as V30. Last Friday, he was officially tagged S30 (left flipper) and S31 (right flipper). He will be known in NOAA’s scientific database as RS30. Two weeks after weaning, his axilliary girth measured 98 cm and his length from tip of the nose to tip of the tail was 124 centimeters. He’s lost some weight since RF30 weaned him and as he figures out the good bits to eat in the ocean, but he’s certainly not the smallest weaner of record. At the same time that RS30 was flipper-tagged, he was vaccinated against morbillivirus, a tissue sample collected, and a micro-chip pit tag (much like the kind used with dogs and cats) was inserted. And all that got done in less than five minutes.
Here are a couple videos provided by volunteers illustrating the development of this young Hawaiian monk seal.
Another surprise visitor—a.k.a. Hawaiian monk seal pup—arrived on Kauai’s north shore last week. Announcing PK2, Kauai’s second pup of 2023. This one was born to RH92, who was born in nearly the same location in 2016. After being regularly reported on Kauai’s east side for several years, RH92 moved to Oahu in 2019 where she seemed to settle on being an “urban” seal after pupping at Kahuku, Oahu last year.

While many female Hawaiian monk seals pup on the beach they were born, some, like RH92, are “pioneer seals,” moving and reproducing on other islands, which helps to disperse the seals among the main Hawaiian islands. By doing so, these pioneering seals are repopulating places the species once inhabited long ago.
Before moving to Oahu, RH92 kept busy:
A few months after weaning, some fishermen contacted DOCARE (Department of Conservation and Resources Enforcement), because a loose dog had attacked a small monk seal. An officer immediately responded, found the dog’s owner, and issued a citation. The seal, with multiple puncture wounds, turned out to be RH92 and was given antibiotics. Thankfully, her small punctures did not become infected and healed quickly.
Soon thereafter, RH92 ventured to Kauai’s East Side where, as a yearling, she began feeding on fish scraps in a canal. Because two other yearlings had drowned, possibly in nets, in the same canal in previous years, she was translocated her to the West Side of the island. Meanwhile, signs near the canal and boat launch were installed and fishers asked not to dump fish scraps in the area. Luckily, fishers complied, because RH92 quickly made her way back to the East Side within two weeks later. Since then, there’s been no problems.
Too, RH92 experienced a severe wound on her head from a large cookie cutter shark bite that exposed her skull. But she quickly healed.
RH92 was born to another seal with a storied past—RK22.

Possibly born in 2001, RK22 abandoned two pups two years in a row before sticking around and mothering. Then, RK22 became known as a “tough love” mother, because she would take her pups swimming at an early age, even leading them outside the protection of the lagoon and beyond the reef into deeper water when they were just one or two weeks old. Over eleven years, RK22 was known to give birth to eight pups. It’s possible the years she didn’t pup on Kauai that she pupped at Niihau. Here’s a recap of her known pups:
2007: After contracting pneumonia during five days of trying to reunite it with RK22, pup was euthanized.
2008: After an attempt to reunite pup with RK22, he was raised for a time in captivity, then released at Molokai. But after developing cataracts, he was re-captured and now lives at Waikiki Aquarium.
2011: RK54. Died after ingesting a fishhook in 2012.
2012: RL14. (Update to come.)
2014: RF22. Died of boat strike in 2015.
2015: RG22. Last known to be hauling out around Oahu.
2016: RH92. Gave birth to second pup in April 2023.
2017: RJ22. Died from drowning, most likely a gillnet fishing entanglement, in September 2017.
RK22 weaned RJ22, her last known pup July 2017, and she was last seen on Kauai in November 2017. She hasn’t been reported since.
