Monk Seal Monday #107: Where Have All the Poipu Seals Gone?

In 2019, the south shore volunteer team was managing two, three, four and sometimes as many as six or seven seals at Poipu at the same time. Challenging times, indeed. Sometimes all seals clustered in one zone; sometimes they spread out over two or even three zones. Of course, the most challenging spot to manage human/seal interactions was the spot that seals liked most, which happened to be the main snorkeling water entrance/exit. In one emergency, lifeguards had to carry a drowning victim over two resting seals, literally, to bring her ashore for CPR. The good news is the rescue was a success, and the person recovered fully.

Then, earlier this year, when the COVID stay-at-home orders were instituted, the volunteer program was placed on hold, and tourism came to a virtual halt. We expected that the seals at Poipu would enjoy resting undisturbed. However, since the pandemic began, the seals seem to have disappeared from the Poipu area. One reason may be there are fewer people on the beaches, so there are fewer calls coming in the hotline. Make sense. But was there something else going on?

Here’s what a review of the data from the daily sightings log revealed:

As expected the number of seals reported in the Poipu area during April-August of this year dropped to a total of 73 sightings. The prior year, during the same five month window, there were a total of 257 reported seal sightings.

A comparison of the individual seals sighted in Poipu in 2019 versus 2020 during that same April-August window revealed the number of unique seals identified in the Poipu area dropped from 21 unique seals in 2019 to 12 in 2020. Too, there’s a slightly different cast of characters hauling out at Poipu this year.

Notably, the notorious “Poipu boys,” a group of rough-housing male seals, have split up with several moving to Oahu, and a couple others moving back to Niihau. From that notorious group, only RG58 remains, and he’s often spotted on the rocks near Brenneckes Beach these days.

Also, two seals from 2019 that occasionally hauled out at Poipu have died—RK30 of old age late last year and RJ36 of a hook ingestion several months ago. Apart from the loss of these two, all the other Poipu regulars of last year are still alive, based on sighting reports across the state.

What this tells us is seal behavior isn’t static, and just when you come to expect the expected out of a seal or group of seals or a particular haul-out location, things change.  As the old philosopher Heroclitus said, “Change is the only constant in life.” Guess he was talking about seals, too.

For more specifics take a look at the list of seals seen in 2019 and 2020.

Monk Seal Monday #98: The Kauai – Kaena Point Connection

According to the Hawaii Tourism website, there’s a legend that connects Haupu on Kauai with Kaena Point on Oahu.  It goes like this:

“On the southeast side of Kauai is Haupu, a peak with many stories attached to it. There’s the giant guardian who shared the name Haupu with the peak on which he lived, whose responsibility was to watch for invaders coming in canoes from Oahu across Kaieiewaho Channel. He once saw the glow of torches on the horizon, saw many canoes and heard many voices. It was a fishing tournament off the western coast of Oahu organized by the chief Kaena, but Haupu mistook this for a fleet of invaders and flung rocks at them. The chief was one of the unlucky ones who lost his life, and his people named Kaena Point in his memory. Pohaku O Kauai, one of the stones the size of a house that Haupu threw across Kaieiewaho Channel, can still be found off Kaena Point.”

There’s another thing that connects Kauai and Oahu—Hawaiian monk seals. It’s not unusual phenomena for Kauai regulars to journey to Oahu, often popping up first at Kaena Point, the westernmost point on Oahu. It’s about an 80-mile journey, point to point.

Most recently, it was RK90 who made the crossing. She was last reported on Kauai at Poipu on May 26th. Then, on May 29th, according to Monk Seal Mania, she was spotted at Kaena Point.

RK90 is an adult female who was likely born on Niihau. Here’s what we know about her:

RK90 appeared on a Kauai Beach as a juvenile in 2013 with a fish hook in her mouth. It was removed, and she was flipper-tagged at the same time. In late 2017, RK90 was sighted on Kauai looking large and very pregnant. Then, she disappeared for six weeks, returning in mid-February looking thin. It’s suspected that she returned to her natal island to give birth, something many, but not all, females do. In May 2018, she turned up hooked again, requiring beach-side intervention. In 2019, RK90 was regularly reported during the first half of the year and, then, not reported on Kauai from July through November.

Thus far this year, RK90 has been reported to the Kauai Hawaiian Monk Seal Conservation Hui hotline on 25 different occasions. She typically ping-pongs between Kauai’s south shore and west side.

RK90’s journey across the Kaieiewaho Channel makes Oahu her third known island destination. She’s not the only seal to journey from Kauai to Oahu. This year alone, these one-time Kauai regulars, including a couple juveniles, have been sighted on Oahu. The year in parenthesis marks their first year reported on Oahu. Note, this year, five Kauai regulars have ventured across the channel.

Kaena Point is a unique landscape on Oahu and important haul out location for Hawaiian monk seals, as well as, numerous native seabirds, including Laysan albatross. It’s a relatively remote and wild coastline. Kaena Point State Park is the gateway to Kaena Point Natural Area Reserve at Oahu’s most northwestern point.

In late April, Reps. Tulsi Gabbard and Ed Case proposed designating Kaena Point as Hawaii’s first National Heritage Area.

According to a joint press release distributed by Reps Gabbard and Case:

“In addition to its natural beauty, Kaʻena is a wahi pana (significant site), a rare cultural landscape with deep significance and meaning to many people,” said Rep. Tulsi Gabbard. “We must work with the community to study the potential for a historic National Heritage Area designation that will help bring the federal resources and protection we need to mālama this special place for generations to come.”

“Kaʻena Point, largely state-owned, is the perfect candidate for Hawaiʻi’s first National Heritage Area given its truly unique cultural, historic and environmental heritage and qualities”, said Rep. Ed Case. “The State of Hawaiʻi’s Department of Land and Natural Resources (DLNR) has already created a management plan for the Ka‘ena Point Stewardship Area to protect one of the last few remaining and easily accessible wilderness areas on O‘ahu.”

“However, DLNR does not have the resources to fully implement the plan” continued Rep. Case. “Creating a National Heritage Area could bring significant federal dollars – with a state or local match – to help augment this plan and develop cultural programs, protect historic sites and improve natural resource conservation. It would also build on already-existing public-private partnerships which is specifically what our National Heritage Areas aim to create and sustain.”

“We are thrilled at the prospect of adding Ka‘ena Point as a National Heritage Area,” said Suzanne Case, Chair of the Hawai‘i Department of Land and Natural Resources. “Ka‘ena Point receives hundreds of visitors weekly to both the state park and the Natural Area Reserve. Additional federal funding would allow us to enhance the visitor experience, expand community and cultural engagement and refine our natural resource management.”

Background: Reps. Gabbard and Case consulted with government and community groups in considering whether and which sites should be considered for National Heritage Area designation. H.R.6603 incorporates various comments, including a specific prohibition on federal acquisition of the land.

For years, Ka‘ena Point has suffered degradation and damage from erosion, invasive species and off-road vehicles and other damaging recreational use that destroyed vegetation, which made it unsuitable for nesting birds.

After the State established the region as a Natural Area Reserve in 1983, vehicular access to most of the area was blocked. The region can still be accessed via hiking trails, but those who come to the area must abide by strict conditions which has allowed nesting birds to return to the area.

Remote Kaʻena Point is the site of the last intact sand dune ecosystem in Hawaiʻi and is said to be named after a sibling of the Hawaiian goddess Pele. Kaʻena Point also includes a leina ka ‘uhane, an important recognized cultural site that, according to some Hawaiian traditions, is where the souls of the deceased leapt into the next plane of existence. Ka‘ena is also home to various protected species including laysan albatrosses, wedge-tailed shearwaters, monk seals and fragile native plants. Migrating whales can also be seen in the area during the winter months.

National Heritage Areas are locations throughout our country designated by Congress to recognize unique cultural and historic sites found nowhere else in the world. Though not part of the National Park System or otherwise federally owned or managed, the U.S. government through the National Park Service, funds and participates in partnerships with state and local governments and communities to foster coordinated conservation, recreation, education and preservation efforts. From designation of the first National Heritage Area in 1984, there are now 55 nationally, but none in Hawaiʻi.

Monk Seal Monday #72: R376 Is Thriving

In March 2018, called the hotline to report an adult Hawaiian monk seal hauled out on Poipu Beach with something dangling from her mouth. What’s more, the seal looked skinny. The concern with a report like that is always that a Hawaiian monk seal has ingested a fish hook and is unable to forage on her own. After consultation with NOAA officials and veterinarians, it was decided to conduct a physical examination of the seal.

Turns out, a fish bone was lodged between the seal’s hard palette, left inner cheek, and tongue, and the dangling matter hanging from her mouth was a large octopus arm that had gotten caught on the fish bone.

The seal wasn’t flipper-tagged, but she was known as R376. After removing the fish bone, injecting her with an antibiotic to combat any infections, and flipper-tagging the seal (7AU left and 7AV right), she was released.

R376 isn’t seen around Kauai often. In fact, she’s only been reported to the hotline nine times this year, usually on the south shore. It’s suspected she spends most of her time on Niihau. But she turned up on Kauai at just the right time one-and-a-half years ago. And, now, her most recent sighting shows she’s continuing to thrive. In fact, her size is such that there’s some speculation she may be pregnant. Now, how’s that for a survival story!

Field Report: March 2018

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.

Monk Seal Monday #15: R376 Response

 

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.

Small wound and infection from embedded fish bone.

 

Fish bone (top) and octopus tentacles (bottom).

R376/7AU was transported back to Poipu and released by the Kauai team by 6:30 p.m. The seal entered the water and departed the area.

 

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.
