Monk Seal Matriarchs #191: The Legacy of RK22

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.

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.

April through August 2019 – These 21 individuals comprised the 257 reported seal sightings in the Poipu area from Shipwrecks to Lawai Beach):

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 #82: Meet the 2019 Top Ten

The numbers are tallied. Below you’ll find the top ten “reported” Hawaiian monk seals on Kauai for 2019. By reported, we mean those monk seals that were reported—and identified—to the Hawaiian Monk Seal Conservation Hui hotline. (See a monk seal on the beach? Report it to 808-651-7668.)

Keep in mind, many things affect this list. Monk seals often have favorite locations where they haul out. If a monk seal favors a location that happens to be easily accessible by humans, bingo, that seal will be reported more often to the hotline. Of course, monk seal moms and their pups rack up a high number of reported sightings, because they stick to the same beach for weeks on end. Molting monk seals, too. As this list will also reveal, young monk seals–especially young males–are often sighted and reported, too, because they tend to make themselves noticed;-)

To make this list a little more interesting, we’ve included only those tagged seals, meaning pups are not included until they are weaned and tagged.

So, here goes:

1. With 122 reported sightings, five-year-old male R3CX tops our list. He was flipper-tagged as a youngster at Keoneloa (colloquially known as Shipwrecks) beach in March 2015. Since then, he’s been commonly seen roughhousing with other males along the south shore and has been displaced from dangerous areas on more than one occasion. He was last seen on November 30th at Poipu.
2. With 117 reported sightings, four-year-old male RG58 follows close behind. Not surprising since they can both be found hauled out on the same beach or roughhousing in shallow water. Born to RH58 in 2015 on the north shore, RG58 is regularly sighted on the south shore. He was last reported today at Poipu.
3. With 116 reported sightings, six-year-old female R7GM ranks third. Those numbers were boosted by the fact that she molted this year. She was last reported on the north shore on December 27th.
4. With 99 reported sightings, six-year-old male RN44 ranks fourth this year, also boosted by his reported molting. RN44 was born to RH58 in 2013 on the north shore where he’s a regular and has been reported interacting with weaners. He was last reported on the north shore on December 27th.
5. With 97 reported sightings, mature female RK13 ranks fifth this year, boosted in her numbers by her molt. Most of the sightings come from the east side; however, she sometimes pops up on the south and west side of the island. She’s also been known to swim up and log in canals. This year, RK13 was displaced from the road edge at Fuji Beach, Kapaa at 3:00 in the morning after calls from the police reported she was on the road’s edge and in danger of being run over. RK13 was reported today to be hauled out on the east side.
6. With 77 reported sightings, sub-adult, four-year-old male RG22 ranks sixth. He was born to RK22 on the north shore but quickly made his way to the south shore, hanging out with the boys on the south shore. Once, he was photographed wearing a pair of swim goggles around his neck. Luckily, they fell off after a couple days. He was last reported on the south shore on October 10th but has since started to wander and was recently sighted off Hawaii Island.
7. With 73 reported sightings, mature female RK30 ranks seventh. She’s approximately 21 years old and has given birth to 11 known pups, including RL30 this year. She was last seen on November 8th at Mahaulepu.
8. With 68 reported sightings, one-year-old female RKA2 ranks eighth. She was born on a remote beach along Na Pali Coast in 2018 to RK30. She was last reported on December 20th on the east side.
9. With 62 reported sightings, eight-year-old female RK52 ranks ninth. Her sightings are bolstered by two things: she weaned her first pup this year, and she was reported molting. RK52 favors north shore beaches. She was born to RH58 and was last reported on a north shore beach on December 22nd.
10. With 58 reported sightings, three-year-old female R1NS rounds out our top ten list. She was flipper-tagged on the east side in 2017 and is notable for her natural bleach marks on the first three digits of her left fore flipper. She was last sighted on the north shore on December 29th.

Monk Seal Monday #59: The Regulars

Every month, anywhere from 30 to 38 individual Hawaiian monk seals are reported to the Kauai Hawaiian Monk Seal Conservation Hui. But just who are these regulars? Here’s a look at the top ten most reported Hawaiian monk seal sightings on Kauai this year to date.

Keep in mind, many things affect this list. Monk seals often have favorite haul out locations. If a monk seal favors a location that happens to be easily accessible by humans, bingo, that seal will be reported more often to the hotline.

Then, of course, monk seal moms and their pups rack up a high number of reported sightings, because they stick to the same beach for weeks on end. As this list will also reveal, young monk seals–especially sub-adult males–are often sighted and reported, too.

1. With 83 sightings, adult R7GM tops the list of most reported monk seal sightings on Kauai this year.  A female, it appears R7GM may be pregnant for the first time. If she pups on Kauai, her chances skyrocket for remaining at the top of this list for 2019.
2. With 81 sightings, R3CX ranks second for the most reported monk seal sightings on Kauai. R3CX is a five-year-old male commonly seen roughhousing with other young males on Poipu Beach.
3. With 65 sightings, RG58 ranks third for the most reported monk seal sightings on Kauai. RG58 is a four-year-old male who also prefers the busy beaches of Poipu. His mother is the renown RH58, also known as Rocky.
4. With 56 sightings, RB00 ranks fourth for the most reported monk seal sightings on Kauai. The year’s first report of RB00 came two days before she gave birth. She nursed for 54 days and immediately left Kauai after weaning her pup. Recently, RB00 was sighted on Maui. RB00 also counts Rocky as her mother.
5. With 53 sightings, RK52, yet another offspring of the prolific Rocky, ranks fifth on our list. She provided us with Kauai’s second pup of the year. She nursed for 36 days.
6. With 53 sightings, RN44 ranks sixth for the most reported monk seal sightings on Kauai this year. He is a healthy six-year-old male, frequently sighted on his natal beach on the North Shore of the island. His mother is also Rocky.
7. With 52 sightings, RL08 is the grandson of Rocky. He was born to RB00 earlier this year and nursed for a whopping 54 days.
8. With 50 sightings, RK58 ranks eighth for the most reported monk seal sightings on Kauai this year. Another pup of Rocky’s, RK58 was abandoned by his mother in 2018 and spent several months in rehab at Ke Kai Ola before being released back on Kauai.
9. With 41 sightings, RK30 ranks ninth for the most reported monk seal sightings on Kauai this year. RK30 is pushing 20 years of age. She’s also one of the most storied monk seals around, having survived many threats to her life. Read more about RK30 here.
10. With 40 sightings, RG22 ranks tenth for the most reported monk seal sightings on Kauai this year. RG22 is another four-year-old male who loves to roughhouse with the boys at Poipu.

Monk Seal Monday #32: Molting

About the first of the month, two-year-old RH92 was reported to have started her annual molt. She joins four other seals known to have molted this year thus far: R1KT, R3CX, RG22, and V2.

Hawaiian monk seals experience what’s called a “catastrophic molt,” meaning the loss of the top layer of skin and fur happens in one concentrated period of time, rather than continually throughout the year. The molting process can take one to two weeks. Because molting requires great energetic resources, during this time, the seal will usually stick pretty close to the beach, often spending the night tucked high up the beach and under bushes.

Molting is a vulnerable time for monk seals, another reason to encourage folks to keep dogs on leashes. Typically, the molt starts on the belly, flippers, muzzle, and scars. Then, moves to the back. The molting pattern isn’t exactly “attractive.” A seal with patches of dead skin falling off can often cause beach-goers concern, thinking the seal is sick or, even, dead.

Adult females will often molt soon after they wean their pups. Also, any seals outfitted with a telemetry tag near its molt will lose it during the molt. (If you happen upon a telemetry tag on the beach–it’s a rare event but it has happened–please call the monk seal hotline to report it.)

Basically, seals molt, because their coat gets dirty. After spending long bouts of time at sea, algae will often grow on their fur. If you see a seemingly green-colored seal, you’ll know he or she is nearing his/her molt.

After molting, monk seals regain their dark gray to brown color on their dorsal (back) side and a light gray to yellowish brown color on their under (ventral) side. This difference in coloration is known as “countershading.” From below, the seal’s light belly blends in with the sunny surface of the ocean. From above, the seal’s darker back is closer in color to the dark ocean floor. This serves as camouflage for seals. It helps them sneak up on prey, as well as, hide from sharks and other predators.

Monk Seal Monday #24: Summer’s Heating Up

[One day late. Apologies.]

RK42
Now has a bleach mark: V42. This will make her easy to identify from a distance. Also, she’s still hanging around her natal beach–one that happens to be popular as a somewhat off-leash dog park. So, please leash your dogs, and if you get a chance to kindly request someone else to do the same, that would be great. If there is any kind of dog-seal interaction, please call the hotline at 808-651-7668.

Here’s another view of RK42, looking as charismatic as any charismatic megafauna and one reason why many people fall for these monk seals. She’s also been seen hanging around other juvenile seals, as is typical for this age.

PK2
We have another pup. (By the way, it’s looking like a record may be broken this year for the highest number of pups born in the Main Hawaiian Islands. Pretty exciting. And good news, especially coming after last week’s report of three deaths due to toxoplasmosis.)

Meet PK2, born to our ever reliable, survivor RK30, on her favorite remote pupping beach along Napali Coast. Pup was born on or before June 18. Any guesses as to gender? (Scroll down to third photo.)

RN02
This five-year-old male was translocated from Big Island to Niihau in 2013 after he repeatedly interacted aggressively with swimmers. Shortly after arriving at Niihau, he swam across the channel and has since been regularly sighted on Kauai’s South Shore, sometimes cruising among swimmers, as he’s been doing this summer. With the increased number of beachgoers due to typical summer visitor season and closure of beaches on the North Shore, this can turn into a rather chaotic scene. (Remember, please do not engage with monk seals, especially in the water, for human safety, as well as, the long-term safety of the monk seal. Let’s keep wild seals wild.) In addition to swimming among snorkelers, RN02 has been observed calling to other resting seals and giving them a good nudge when they don’t respond to his vocalizations. (Maybe he needs to be reminded to, “Let sleeping seals lie.”)

Here’s a sample of a few days in the life of RN02. One recent afternoon, a report was made to the hotline that a monk seal was in a hole. Turns out, RN02 had decided to investigate a rather deep pit that had been dug by children (who had already departed). RN02 stayed there for, at least, three hours. The next day–a windy day–he was, finally, sleeping quietly elsewhere when a beach umbrella hit him in the head. That was enough to get him to head for the water. The day after that, he was seen agitating a resting R7AA, and the day after that, he coaxed RG22 off the beach to roll around in the shallows together.

Field Report: November

In November, the Kauai team logged 239 seal sightings. This included 35 individually identified seals. Here’s a look at how the 239 number compares to other months.

November: 239
October: 225
September: 354
August: 236
July: 335

As a reminder, there are numerous reasons that can effect the number of reported seal sightings. Two big ones are the availability of our steadfast volunteers taking their daily beach walks, and the presence of moms with pups and the subsequent “pup sitting” we do. Of course, the seals themselves play a factor in this, too. Maybe there’s some seasonality in foraging that takes them to remote areas of the island where we don’t see them. That’s the thing with animals that spend the majority of their lives at sea–we don’t quite know.

Other November news to note:

• Seal activity continues around Poipu Beach Park with seals swimming among swimmers, snorkelers and the water aerobics class and hauling out on the beach amidst beach-goers. Our advice continues to be for everyone involved to give the animal its space and never approach, touch, harass, disturb it. Remember: Monk seals are wild animals; let’s keep them that way.
• One additional monk seal received its morbillivirus vaccination in November. This virus, similar to distemper in dogs, has not infected the monk seal species. But in a proactive effort to combat an outbreak, the Hawaiian Monk Seal Science Program started vaccinating seals last year. To learn more about the threat of morbillivirus, read this Smithsonian article.
• Two seals “bleach-marked” this month–RG22 as V22 and R340 as V77. To learn more about using Clairol to help identify individuals seals, read this previous #MonkSealMonday report.
• Four seals completed their molts in November, including: RH38, RG58, RK14, RH80. To learn more about molting in Hawaiian monk seals, read this previous #MonkSealMonday report.

Field Report: May 2017

Busy Month De-hooking Seals.

Juvenile male seal RG22 was found with a small hook again on May 1. A team was quickly assembled to capture and attempt hook removal. The original small J hook was no longer visible, however a rusty medium sized circle hook was incidentally found wedged inside the left lower jaw, which required sedation for removal. RG22 was transported to the DLNR base yard and held overnight to await arrival of an Oahu veterinary team to assist. He was sedated and the rusty hook was removed. Radiographs revealed that the smaller hook and was no longer present.

PC: V. Bloy.

On May 11, hooked adult female RK90 was found with large male, R336 at Ahukini Cove. Due to her large size, a skilled NOAA seal handler from Oahu joined the Kauai team. The team isolated and captured RK90 with crowding boards, removed the large circle hook and immediately released her to re-join R336.

PC: M. Miyashiro.

 

Seals of Concern Updates.

Subadult male, RN02, continues to interact with people in the water, but the level of interaction seems to have decreased somewhat in May. Fortunately we are seeing that he socializes with seals extensively (and the odd turtle!). He has not made contact with people yet. This is a good reminder to remember NOT to engage with monk seals in the water.

RH92, juvenile female, translocated to the West Side, returned to Lihi canal within two weeks, however we are pleased to report that she is foraging in a wider range along the east coast and spending less time in the canal where fish scrap dumping appears to have decreased due to increased outreach and law enforcement patrols.

We expected RK13 to have extensive scarring and possibly the loss of a nare. Amazingly one month later, her face was completely healed with only a few small scars and both nares patent and normal!

Though wildlife wounds often look disturbing, wild animal medicine demonstrates how resilient wild animals are.
