If you’ve heard about the storm that Kauai weathered over the weekend, some of you may be wondering about our Hawaiian monk seals. (If you haven’t heard about the storm, you can read more about it here.)

The Kauai Hawaiian Monk Seal Conservation Hui does not deploy volunteers to dangerous situations–during storms or otherwise–and didn’t yesterday, either; however, the general public reported four seals hauled out on southern and western shores yesterday. They were all reported to be fine. The brunt of the storm hit Kauai’s north shore. Obviously, monk seals are marine mammals and are much better adapted to handle rising waters than we mere humans.

Now, for the March Field Report:

Sightings:

The Kauai team logged 299 seal sightings this month. This included 30 individually identified seals.

March: 299
Feb: 259
Jan: 336
Dec: 270
Nov: 239
Oct: 225
Sep: 354

New

  • AF (Adult/Female) R376 was observed on Poipu Beach with bait trailing from her mouth and with a significant loss of weight since her previous sighting six weeks prior, suggesting she’d ingested a fish hook. With 13 volunteers assisting, a trained response team crowded her into transport carrier, and she was moved to DOFAW baseyard in Lihue to await arrival of an Oahu veterinary team. A fish bone was discovered to be lodged in her mouth. It was removed, she was given antibiotics and released at Poipu Beach by the end of the same day. Read more about this swift and successful response here.
  • JF (Juveniile/Female) R7AA hauled out onto the shoulder of the road near Brenneckes in Poipu. A visitor called the hotline, and later the seal was displaced into the water and away from the road entirely.
  • Several reports of dogs chasing seals off the beach at Maha’ulepu were reported to the hotline. No seal injuries have been reported. DOCARE has been alerted.
  • A report was made from a fisherman of a seal dead in a net 3.5 miles outside Nawiliwili Harbor. USCG provided vessel support to investigate and possibly retrieve. A large bill fish, not a seal, was found entangled in a large cargo net, partially eaten by sharks.

Updates on previously reports:

  • NG00 is likely still hooked and was not sighted this month. SM (Small/Male) Sighted on Niihau in January. Photos match pictures sent in last September by fisherman of a hooked seal along Kaumakani on Kauai. Seal presents in good condition. Since hook is not life threatening, the Kauai response team will attempt to de-hook him the next opportunity that presents itself.
  • Poipu Keiki Pool: no displacements took place this month.
  • Bleach markings: 3 seals bleach marked this month.
  • Molting activity: no seals molted this month.

Research/Support of Pacific Islands Fisheries Science Center:

  • Subsampled serum samples from R376 for PIFSC and shipped to Oahu.
  • Sub-sampled scat, molt, and tissue plug samples.
  • Logged all seal sightings. Organized photos and reported sightings, molt tallies, survival factors and sent to PIFSC.

R376 in robust body condition on December 21, 2017.

At 9:00 a.m. on Tuesday, March 6, a report was called in to the hotline of an adult female, R376, hauled out at Poipu with something hanging out of her mouth. Our monk seal response team suspected she may have had a fish hook stuck in her mouth and the dangling bits were bait. Upon arriving at the beach 30 minutes later, the organic material was still visible, but what was also evident to the team was that she’d lost quite a bit of weight since her last sighting one month before. The combination of the two issues prompted our local team to reach out to the Hawaiian Monk Seal Research Program–all disturbances/handling of endangered Hawaiian monk seals require clearance–and it was decided a physical examination was warranted.

R376 in thin body condition on March 6, 2018.

With the help of a trained volunteer team, R376 was easily herded into a transport cage and transported to secure location to await the NOAA veterinary team that was en-route from Honolulu to assist with the examination.

At 3:30 the seal was sedated and examined with radiographs taken from the head to stomach; however, no hooks were present. A visual inspection of the seal’s mouth revealed a large spinous fish bone lodged between the hard palette, left inner cheek, and tongue. The organic material dangling from her mouth was a large octopus arm that was caught on the fish bone. A pair of needle nose pliers were used to carefully remove the bone. An antibiotic injection was given, blood samples were taken for post morbillivirus vaccination titers, the seal was flipper tagged 7AU (left flipper) and 7AV (right flipper), and the sedation was reversed.

If you come upon this monk seal (flipper tags 7AU/7AV), please give her wide berth while she recovers and regains her lost weight. But please take photos and report her whereabouts to our hotline: 808-651-7668.

Last week, on a sunny day, our second pup of the year graduated to “weaner” status and was tagged RJ36. After about six weeks of dedicated nursing, RJ36’s mother, RK30, weaned him and headed back to the nourishing depths of the ocean to replenish the approximate one-third body weight she lost during the nearly six weeks she nursed RJ36 to a healthy weaner weight in the neighborhood of 175 pounds.

While the procedure to tag monk seal weaners only takes about five minutes, the effort to tag this pup took much longer–all due to the remote location of where RK30 chose to birth.

For years now, the Kauai Hawaiian Monk Seal Hui has been aided when accessing remote beaches by marine biologist Captain Tara Leota, sole owner-operator of Kauai Sea Rider Adventures. Captain Tara leads small groups of ecologically-minded guests on snorkeling adventures around Kauai. Captain Tara, her crew, and her guests welcomed our tagging team aboard her 25-foot rigid inflatable boat for the adventurous journey to find RJ36.

Currently, the way we track matriarchal lineage of monk seals is by visual observations of mothers and pups. As such, our goal is always to tag pups within days of their weaning. Once weaners start exploring other parts of the island and mixing with other monk seals, we cannot be sure of their lineage. Thus, Captain Tara has likely helped us know with surety the matriarchal lines of six or eight monk seals over the years. That’s a great effort.

We are proud to announce that we have another pup. Fifteen-year-old RH58 arrived from Oahu on Sunday, July 12th. In the midst of stormy weather, on Monday morning, she was found concealed in naupaka bushes with a nice healthy pup–that has since been confirmed male. This is RH58’s ninth pup born on Kauai since 2006. While she has spent her adult life foraging the waters around and hauling out on the beaches of Oahu, like many monk seals, RH58 returns to her own natal beach to birth, as well.

Our third pup born to RO28 has weaned, and his mother returned to Oahu a few days later, accompanied by an untagged male seal, Temp 319. This third weaned pup is tagged G28/G29 and goes by the ID name of RG28. When hauled out, he likes to hang out in rocks. These weaned pups seek rocks and objects to nestle against, possibly missing mom, and are vulnerable to people and loose dogs. They are very naive and curious, as all young are when they are learning about their environment and how to feed and socialize. Unfortunately their “cuteness” gets them in trouble when people approach them, try to pet or swim with them, and–most dangerous for taming a wild animal–try to feed them.

One. On tax day, April 15, 2015, we welcomed our first Kauai pup of the year when RK13 gave birth to a big, healthy female. Volunteer Gary Langley reported the pup nursed several times during her first morning of life, and while still a few hours old, she took her first swim. All during PK1’s first week of life, the pair was visited by several males RK05, RV18 and a new-to-us monk seal, Temp 310, who chased all others the away. RK13 is an older, productive female that has only pupped once on Kauai. She usually pups on Ni’ihau.

Two. On May 15, 2015, we welcomed PK2 to Kauai, born to RK22, making this her fifth pup in five years. She’s sure turned into a good mother after a rough start in which she abandoned two pups two years in a row. But she can be a little wary, and as with all mothers in the animal kingdom, can be quite protective of her offspring. A few wildlife viewing measures are always important to keep in mind when near RK22 (and any other monk seals): Give them plenty of space; stay out of their line of sight; position yourself downwind; and camouflage yourself by staying low to the ground in and amongst bushes when possible. The goal is to watch without disturbing.

Three. On May 26, 2015, we welcomed PK3 to Kauai, born to RO28 who arrived from Oahu only days before. This young mother was born on Kauai but likes to spend her adult days on Oahu–until it’s time to pup. Then, she returns to her natal beach. Like RK22, this mother is very protective and has been aggressive towards people approaching her on the beach or in the water, so we request people give her a wide berth. Amazingly, volunteer Julie Honnert was on the beach with her video camera running when the big event happened. Check out this amazing video!

So, three, so far. And we expect more. Stay tuned. And, as always, if you’d like to volunteer with the Hawaiian Monk Seal Conservation Hui on Kauai, please email kauaiseals@gmail.com. And if you run across any seals on the beach, please take a quick health assessment and report any sightings to the hotline–808-651-7668.
