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 #92: The Tragic Loss of RO28

This slideshow requires JavaScript.

Sadly, on April 1, 2020, after a 10-week-long battle with toxoplasmosis, a deadly parasitic disease, the adult female seal RO28 passed away.

Also known as “Pōhaku,” RO28 was 14 years old, in the midst of her prime reproductive years, when she died. She was born on Kauai’s north shore in 2006 to RK06. (RK06 was tragically shot to death while she was carrying a full-term pup. The pup did not survive the shooting.)

Over the years, RO28 has made her fair share of appearances on these virtual pages. Throughout her life, she gave birth to seven pups, the first six of which she pupped and raised until weaning along the same stretch of coastline on Kauai’s north shore where she was born. (It’s not uncommon for females to pup near their own birth site.) However, RO28 spent her recent years on the island of Oahu, only returning to Kauai to give birth.

Here’s a recap of what we know about RO28’s life:

• In her early adolescent years, RO28 spent much of her time hauling out on rocks along the Poipu coastline.
• On Good Friday in 2010, she was successfully de-hooked.
• She was first sighted on Oahu at Kaena Point during the 2010 Semi-Annual Hawaiian Monk Seal Count. She was re-sighted twice shortly thereafter, once with a fresh cookie cutter shark bite on her back.
• In 2013, RO28 gave birth to RN30 who has traveled to Oahu and has been regularly sighted on Kauai’s north shore.
• In 2014, RO28 gave birth to RF28 who has ventured to Niihau and is also commonly reported along the Poipu coastline.
• In 2015, RO28 gave birth to RG28 who often hauls out on Kauai’s South Shore. This birth was miraculously captured on video by one of our volunteers.

• In 2016, RO28 gave birth to RH80 who regularly circumnavigates Kauai.
• In 2017, RO28 gave birth to RJ28 who can be found on beaches on Kauai’s north shore and east side.
• In 2018, RO28 gave birth to RKA4 who was last sighted at Kipu Kai.

In 2018, RO28 and two other mothers pupped near each other, resulting in multiple pup-switching incidents. This occurs in the Northwestern Hawaiian Islands where more females are pupping on fewer suitable habitat. RO28 was successfully reunited with RKA4; however, one of the other moms, RH58, also known as “Rocky” eventually showed aggressive behavior toward her pup, and he was rescued by NOAA and successfully raised and eventually released back to the wild.

RO28 pupped on Oahu last year and weaned her pup. Unfortunately, the pup tragically died some time thereafter. NOAA reported, “The circumstances surrounding her death indicate that she did not die of natural causes.”

The loss of RO28 makes thirteen known deaths due to toxoplasmosis.

The first documented monk seal death due to toxoplasmosis occurred in 2001. That number has now risen to at least 13 monk seals, making it a leading threat to the main Hawaiian Islands population. Because seals disappear and die without being discovered, the actual number of deaths caused by toxoplasmosis is likely much higher. Unfortunately, the data indicates more females die than males, presenting another challenge to recovery of the species. According to NOAA Fisheres, “Every lost female means that her future pups, and their future pups, are lost to the world.”

What’s unique about RO28’s case is she was only the third monk seal with toxoplasmosis to be rescued alive. While the other two passed away within 48 hours, veterinarians and care-givers were able to work with RO28 for 10 weeks. During that time, she showed improvement at times, providing science with invaluable information that will, hopefully, one day allow for successful medical care for toxo-infected monk seals.

The parasite Toxoplasma gondii is a microscopic, single-cell organism. Just one of their eggs—known as oocysts— is enough to kill a monk seal. A single cat can excrete 145 billion eggs per year in its feces, according to DLNR. It’s a staggering number.

According to this NOAA report, “The parasite that causes ‘toxo’ sexually reproduces in cats, which shed T. gondii eggs into the environment via their feces. The feces of just one cat contains millions of T. gondii eggs that survive in the environment for many months.

“Any warm-blooded animal, including humans, can contract toxoplasmosis by ingesting a single T. gondii egg — and cats are essential for the reproduction and spread of the parasite.”

The loss of RO28 is yet another reason to keep cats indoors to protect cats and Hawaii’s native wildlife. Please.

Monk Seal Monday #26: RO28

Twelve years ago, Kauai’s newest mom, RO28, was born in nearly the same spot she gave birth last week. While monk seals tend to have unique personalities and proclivities, it’s not uncommon for females to return to their natal beach sites when it’s their time to give birth. In fact, RO28 has pupped along the same stretch of coastline for six years in a row.

What’s more unique than that is the fact that RO28’s six pups are all still alive.

With all the threats facing Hawaiian monk seals–entanglements in marine debris, ingested fish hooks, intentional harm by humans, and the growing threat of toxoplasmosis–somehow all of RO28’s six pups have, thus far, evaded them all.

Point of note: RO28’s mother was RK06 who was shot by a fisherman in 2009. Even RO28 herself has run into some challenges. In 2010, she turned up with a fishhook in her mouth. Shortly after it was removed, she crossed the 100-mile open ocean channel to Oahu where she spends most of her time–until it’s time to give birth. Then, she makes the return journey to her natal site. Within a few days of arriving, she pups. The timing is impressive.

Here’s a recap of RO28’s pupping history:

• In 2013, RO28 gave birth to RN30 who has recently traveled to Oahu
• In 2014, RO28 gave birth to RF28 who now hangs out at Niihau
• In 2015, RO28 gave birth to RG28 who often hauls out on Kauai’s South Shore. This birth was captured on video by one of our volunteers and can be seen here.
• In 2016, RO28 gave birth to RH80 who regularly circumnavigates Kauai
• In 2017, RO28 gave birth to RJ28 who can be found on beaches on Kauai’s North Shore and East Side

 

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.

Field Report: Summer

2017 pups are all weaned and tagged!

All weaned pups this year are males (all three last year were females, born to the same moms at same locations!). RK30’s pup born along the Na Pali coast, is a nice big healthy weaner, now known as RJ36 (tagged J36/J37). We are grateful to Captain Tara Leota and Kauai Sea Riders for assistance to monitor and deliver the Kauai team to tag this pup.

RK22 weaned her pup RJ22 (tagged J22/J23) on the northeast coast and was found one morning entangled in in monofilament fishing line. Fortunately, while we were monitoring,  he was able to free himself from the fishing line. This demonstrates why it is so important to check the seals regularly–and to pick up marine debris whenever possible.

The last pup to wean, was RO28’s pup now known as RJ28 (tagged J28/J29). This pup remains on his natal beach while RJ22 has already started exploring more of the coast, moving south.

Seals of Concern Updates

RH92, juvenile female was translocated from Kapaa to PMRF in March. We are pleased to report that even though she returned to the Fuji Beach area she is no longer logging nor feeding on fish scraps in the canal. She continues to forage normally along the east coast and just finished her first molt.

Another yearling female, RH38, is getting ready to molt along the north shore, and we are monitoring her closely as her weight is low.

Unusual hook discovery

An unknown, untagged, clean adult male seal showed up on the south shore with a large J-hook stuck in his back. A second J-hook was attached with a metal leader and there was 17 feet of very heavy (400 lb) monofilament trailing. Coordinators were able to cut away all of monofilament and the dangling second hook.

The remaining hook embedded in the skin is non-life threatening and will eventually come out on its own, however we will closely monitor this seal and intervene if necessary. Fishermen have informed us that the gear that hooked the seal is used to catch marlin by trolling behind a fast moving boat.

Meanwhile, in Waikiki

One of Kauai’s longtime breeding females, RH58 or “Rocky,” pupped on at Kaimana Beach in Waikiki on Oahu–and instantly became the darling of beachgoers. The mom and pup, a female, provided NOAA staff and volunteers with additional concern when they swam inside the Natatorium by way of an opening in its crumbling seawall. Eventually, once RH58 weaned her fat and healthy pup, the pup was relocated to a more remote location for her safety. As we’ve discussed here many times, young seals are most vulnerable right after weaning. This is a time they spend exploring their natal beach, learning what’s edible and what isn’t. At this age, they are quite curious and social, approaching other seals and, even, people on the beach and in the water as they go about figuring out how to survive as a seal on their own. For her safety, scientists decided to move RH58’s pup to a more remote location.

And at Midway Atoll

A mother monk seal bit a woman–an employee with U.S. Fish and Wildlife Service–several times while the woman was swimming in the only section of water open for recreational use. The monk seal approached the woman from an adjacent beach where she had pupped. The woman remained on Midway to recover from her injuries. While this incident is extremely unfortunate, it is a good reminder that monk seals are wild animals and that each seal is an individual, each reacting differently to what might seem to be similar situations.
