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.

Monk Seal Monday #75: Tracking RH38

This year has been one of downs and ups for three-and-a-half-year-old RH38. It started with a drastic weight loss that earned the female a visit to Ke Kai Ola on Hawaii Island where she became the first wild Hawaiian monk seal to undergo a CT scan. After an extended stay and recovery from near death, RH38 was returned to Kauai, and it looks like she’ll end the year on a high. Turns out, RH38 is a survivor, like her mother. RH38 was born to the legendary RK30 in May 2016.

Thanks to a telemetry tracking device attached to her back when she was returned to the wild, scientists are able to keep an eye on her movements. (The telemetry device will fall off the next time RH38 molts, if not before.)

The “tracks” resulting from the device show RH38 has logged quite a few miles cruising nearly the entire circumference of Kauai.

Here are some photos of RH38 from October that show her healthy body condition.

  • 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.

In March, after RH38 seemingly shrank to nothing more than a sad bag of bones, she was scooped up and flown to Ke Kai Ola on Hawaii Island. There, after days turned into weeks and a few tests turned into dozens, she was finally rolled into another hospital–the North Hawaii Community Hospital–for a full-body CT scan. It was the first CT scan performed on a wild Hawaiian monk seal. It was then veterinarians were finally able to turn this touch-and-go patient’s health around, and a couple weeks ago, she became the 28th patient of the monk seal hospital to be admitted and returned to the wild. (See more here.)

These are photos of RH38 on the day she was admitted to Ke Kai Ola.

When the three-and-a-half-year-old RH38 was released back on a remote Kauai beach, she looked like a completely different seal. She’d undergone a molt while she spent four-and-a-half months in rehabilitative care at Ke Kai Ola, so her coat looked like she’d taken a side visit to a monk seal spa while she was away from Kauai. She also gained weight. Lots of weight. She was released tipping the scales close to three times what she weighed when she was admitted to Ke Kai Ola.

Here’s a slide show of RH38 making her way to the water on the day of her release. Note her excellent body condition. You wouldn’t know she was the same seal–except her flipper tags prove it.

Since her release, RH38 has been exploring some of her favorite haunts. It’s as if she’d never left. Reports of her whereabouts have come in from the public, including one of some beachgoers approaching a little too close for RH38’s liking. Any time a wild animal spends time in rehab, one concern is whether she’ll show interest in humans upon her release. In RH38’s case, she hasn’t. And that’s a good thing. Maybe she got poked and prodded a little too much at Ke Kai Ola. But this is also a good reminder to encourage people to give monk seals–and all wild animals–plenty of space. When monk seals haul out on the beach, it’s for much needed rest, so when they return to the sea, they’re sharp and alert.

There’s another way biologists track RH38’s travels, and that’s by the satellite tag attached to her back, which is standard for monk seals released after care. (It’ll stay on until she next molts, if it doesn’t fall off sooner.) This allows biologists and veterinarians to keep a remote eye on her and evaluate her behavior. Here is a sample track of RH38’s recent whereabouts.

If you’re wondering about those red lines seemingly on land, RH38 has not evolved into a terrestrial seal. Those are poor quality fixes, typical of satellite tags with wide accuracy ranges. But you get the basic idea. The good news is RH38 has been ranging up and down the coastline in a way consistent with wild Hawaiian monk seals.

Lastly, here’s a video of her release and immediate beeline for the water.

During a weekend in April 2018, a record-setting storm ravaged Kaua’i. Not a square yard of the island was spared. Lightning lit up the sky. Thunder shook the walls of homes down to their foundation. Streams swelled into rivers and rivers into raging water racing for the ocean, sweeping away homes and cars and, even, buffalo en route.

The hardest hit was a stretch of approximately eight miles on the North Shore, beginning just west of Hanalei and stopping at the road’s end at Ke’e. When it was all said and done, one rain gauge measured a 24-hour rainfall of a whopping 49.7 inches. A U.S. record. All that rain triggered rockslides, ripped out sections of the road, and damaged bridges, instantly making Historic Highway 560 impassable. The road closure reduced the number of people on Haena’s beaches from 3,000 to, maybe, three daily.

With so few people on the beach, there was little need for volunteers to help with outreach. However, a few stalwart volunteers who live in the area continued to scout for seals, conducting health assessments and providing reports to the Kauai Hawaiian Monk Seal Conservation Hui.

On Monday, June 17, 2019 the road re-opened to the public for the first time, and by 8:30 in the morning, RK52 was reported on the beach. She’s a regular there. But R313, RK05, RH38, RK14 and several others have been sighted on these beaches, as well.

There are only a few volunteers in the Haena area; however, lifeguards and Haena residents often help out by setting up signs and monitoring seals. To prepare for the return of visitors now that the road is open and the beaches are filling up again, racks filled with signs are stationed every 200-300 yards beginning at Hanalei Colony Resort all the way to the very end of the road at Ke’e Beach Park. This is approximately a 4 mile stretch of beach. We welcome the assistance of all beach users to assist with educating visitors who may approach seals too closely or not understand that seals often haul-out and rest alone along this shoreline. If you’d like to become a trained volunteer, please call 808-651-7668.
