As you may recall, the first Kauai pup was born on April 20, 2018 at Maha’ulepu to RK13. While this pup was with her mother she was known as PK1 (Pup Kauai #1), and then after 37 days of nursing, her mother weaned her, and we briefly captured and flipper tagged her. This process usually takes less than five minutes and includes a brief restraint while plastic flipper tags are applied in the webbing of the rear flippers. Her tags read K42 and K43, making her official ID RK42. The R indicates that she is part of the Main Hawaiian Island population and the K indicates she was born in 2018, and finally the 42 is her unique ID. During the tagging process her length and girth were also measured, a microchip was injected under her skin, and she was given her first vaccination against a virus in the measles family known as morbillivirus, also known as distemper in other species. You can learn more about this virus and the monk seal vaccination program here.

As previously reported, RK42 became entangled in hook and line fishing gear on July 28th, which left a large fish hook in her mouth. The Kauai team quickly responded and captured her on the beach and removed the hook. The hook was a rather large barbed J-hook that was somewhat difficult to remove, primarily due to the sharp barb which caused some tissue damage in her mouth and mild bleeding. She spent the rest of that day resting normally at Maha’ulepu, but has not been seen since.

It is not uncommon for young seals to find a quiet out of the way places to haul-out, so we hope that is the case. In fact, it’s happened before. In June 2009, R5AY gave birth on a North Shore Kaua`i​ beach to a female pup who was eventually tagged RA20. After weaning, as RA20 started to explore, she all but disappeared. Time between sightings would stretch into months and years. Then, surprising everyone, she started popping up on Maui and Hawai`i Island beaches. In 2017, she gave birth to her first pup. Unfortunately, the pup did not survive. However, earlier this year, RA20 gave birth to a second, healthy pup.

As with most wildlife, surviving to adulthood is not easy. First year survival rates for monk seals in the Main Hawaiian islands is approximately 80%. The hooking was a very minor so we have little reason to believe it caused her longer term problems, but again young monk seals face many threats, both anthropogenic and natural. However, we are optimistic we will see her hauled out somewhere sometime soon in good health.

This is a good reminder to report all monk seal sightings on Kaua`i by calling our hotline–808-651-7668.

FOR IMMEDIATE RELEASE

Endangered Hawaiian monk seal rescued on Kaua‘i stabilizes at Ke Kai Ola, a dedicated hospital for monk seals on Hawai‘i Island

PC: G. Langley

(Kailua-Kona, Hawai‘i – Aug. 6, 2018) – A Hawaiian monk seal pup recently rescued on Kaua‘i is now in stable condition at Ke Kai Ola, The Marine Mammal Center’s hospital and visitor center in Kailua-Kona that is dedicated to the endangered marine mammal. The male pup, RK58, was born on July 16 to monk seal RH58 (Rocky) and involved in a switch with another mom-pup pair on the same beach. Multiple attempts at reunification were ultimately unsuccessful, leading to the decision to rescue the pup before weather conditions prevented intervention.

“While surprising to see a second mom-pup switch on the Main Hawaiian Islands, The Marine Mammal Center is prepared to provide rehabilitative care to any Hawaiian monk seal in need,” says Dr. Claire Simeone, the Center’s Hospital Director at Ke Kai Ola. “Each individual animal’s survival is critical to support the recovery of the population, and we are grateful to give RK58 a second chance at life.”

Pup switches are a natural occurrence that are observed annually in the Northwestern Hawaiian Islands, but are less common in the Main Hawaiian Islands due to the lower density of moms and pups. Last month, experts from The Marine Mammal Center and the National Oceanic and Atmospheric Administration (NOAA) made the decision to rescue Sole, a young male pup born on Moloka‘i that was also involved in a mom-pup pair switch. This is only the second observed occurrence of this type of switch in the Main Hawaiian Islands.

“This is an unfortunate but natural occurrence that we do see in the wild,” says Jessie Bohlander, Research Marine Biologist and Acting Program Lead for NOAA Pacific Islands Fisheries Science Center’s (PIFSC) Hawaiian Monk Seal Research Program (HMSRP). “We are lucky to have a great partnership between NOAA, the Hawaiʻi Department of Land and Natural Resources (DLNR), The Marine Mammal Center, and others to quickly handle these situations and are hopeful that RK58 will do well at Ke Kai Ola and be successfully released back to the wild.”

On July 16, Rocky gave birth on a remote Kaua‘i beach near two other mom-pup pairs. The animals were observed daily by trained biologists and volunteers with NOAA and DLNR. At about five days of age, volunteers saw RK58 switch nursing mothers with another pup. NOAA and DLNR personnel initiated reunification attempts, and Rocky took her pup back immediately with no aggression or confusion.

Late last week, RK58 switched mothers again. Due to a difference in ages of the pups and a concern that RK58 would not be able to nurse long enough from a different mom, reunification efforts were again attempted. Unfortunately, Rocky rejected her pup and displayed signs of aggression toward him. Rocky then left the area, and her pup was left on its own after having nursed for a total of 19 days, well short of the typical 35 to 50 day nursing duration. It was clear that intervention was critical to ensure the pup’s survival.

 

“As we do with all our monk seal moms and pups, we worked hard to ensure Rocky had a successful nursing period. We did everything we could to keep Rocky and her pup together, but despite our best

efforts, Rocky stopped nursing her pup and we had to intervene to save the pup’s life,” says Jamie Thomton, the Kaua‘i Marine Mammal Response Program Coordinator with NOAA Fisheries Service. “However, we are fortunate that the Hawaiian monk seal hospital Ke Kai Ola is prepared to accept orphaned pups like RK58.”

Dr. Simeone, along with Mr. Thomton from NOAA and Mimi Olry from DLNR, led the rescue effort for the pup this past Saturday ahead of anticipated weather conditions that would make a transport impossible. The United States Coast Guard provided a flight for Dr. Simeone on a C130 from Honolulu to Kaua‘i, and then on to Hawai‘i Island to safely transport the seal to Ke Kai Ola. Dr. Simeone accompanied the seal throughout the transport and is providing supportive care at the hospital with the assistance of staff and volunteers.

During an initial exam, Dr. Simeone noted that the pup is malnourished but otherwise stable. He is currently receiving nutrition in the form of electrolyte tube feedings, and as he grows stronger will transition to eating whole fish. The team plans to quarantine RK58 from Sole until veterinarians can confirm that RK58 is free from infectious disease. Sole continues to progress well in rehabilitation as he makes the transition from tube feeding to free feeding on whole fish. Human interaction will be minimal to ensure that both seal pups stay wild. Once each seal reaches a healthy body condition and is able to forage on its own, it will be released back to the wild.

It is rare to rescue a monk seal from the main Hawaiian Islands, and this young pup is only the third pup from the main islands to be rehabilitated by the Center. The Marine Mammal Center is a member of the Pacific Island Region Marine Mammal Response Network and is responsible for monitoring the seals that haul out on Hawai‘i Island.

The Marine Mammal Center has rehabilitated 23 monk seals since opening Ke Kai Ola in 2014, the majority of which were rescued from the Northwestern Hawaiian Islands. The Center is proud to partner with NOAA to support conservation efforts for the Hawaiian monk seal. Researchers estimate the current monk seal population to be about 1,400 animals, and about 30 percent of those monk seals are alive today directly due to conservation efforts led by NOAA and its partners.

HOW THE PUBLIC CAN HELP

Members of the public should keep a safe distance from monk seals and report sightings on Hawai‘i Island to the Center’s response team at the 24-hour hotline: 808-987-0765.

Volunteers are needed at the Kona hospital and visitor center in a variety of roles, including animal care, education and response. Interested individuals should visit MarineMammalCenter.org/KKO-volunteerto learn more about the opportunities available.

IMG_0321The eighteen-year-old Hawaiian monk seal known to science as RH58 but more commonly known to thousands of her fans as “Rocky” has returned to Kaua`i and given birth to her 11th pup on a remote stretch of coastline where she has pupped nine previous times.

That news has allowed many, many, many people in the Hawaiian monk seal world to breathe a sign of relief, because they won’t have to worry quite as much about the health and safety of mom and pup and beachgoers as they did last year when Rocky surprised everyone by pupping on busy Waikiki Beach. (Reminder: Protective moms have been known to charge snorkelers and swimmers in the water, so steer clear.)

RH58 nurses pupRocky herself was born on another beach on Kaua`​i back in 2000. At some point in her adulthood, she crossed the 70-mile-wide Ka`ie`iewaho Channel and spends much of her adult life navigating the waters and coastline of O`ahu.

She gave birth on the shores of Kaua`i for the first time in 2006 when she was six years of age.

She continued to live on O`​ahu and pup on Kaua`i with little to no trouble (or drama!) until four years ago.

RH58 nuzzles pupIn 2014, Rocky and her pup were involved in a dog(s) attack. Her pup (RF58) received over 60 bite marks on her body, developing a couple abscesses around her neck. A NOAA veterinary team responded with antibiotics. (This was the same attack in which RK28‘s young pup was killed.) Remember, it’s a state law that all dogs on beaches must be leashed.

Then, in 2017, Rocky pupped on Waikiki Beach, igniting her headline-making days and introducing Hawaiian monk seals to tens of thousands of visitors from across the globe. Their first few weeks together were live-streamed by a local media outlet, and the pupping event sparked numerous Facebook fan pages.

In January 2018, Rocky became a grandmother for the first time when her female pup–RB00–gave birth to a pup (R00K) on Lāna`i. Then, she almost became a grandmother a second time when RK52 pupped earlier this year. Unfortunately, that pup was stillborn. RK52 was born in 2011 and officials have hopes she will give birth to many healthy pups in the future.

Hawaiian monk seals can live to be 25 to 30 years old in the wild, so there’s a good chance Rocky will continue to contribute to the recovery of her species in the years to come. Perhaps Rocky’s next great headline will come in six or seven years when she, RB00, and R00K all three pup in the same year. Now, that would be big news.

Keep returning to this page. Photos and video will be added throughout the next few days.

Meanwhile, if you’d like a historical review of Rocky’s whereabouts when she’s on O`ahu, try searching for “RH58” on the Monk Seal Mania website.

Two more pups have joined the Hawaiian monk seal population.

On June 26, RK28 gave birth to a healthy pup, her first pup born on Kauai in four years. Here is PK3 on the day of his/her birth.

rk28 and pup day oneAs you may recall, in 2014, RK28’s two-week old pup was tragically killed during a night-time dog(s) attack that also left dozens of puncture wounds on four other seals, including RK28 who likely valiantly tried her best to protect her pup. It was a tragedy, especially since it’s one that could have been prevented simply by not letting dogs run free. Please share this story when chatting with folks on the beach about the various threats these endangered monk seals face. To read more about this tragedy, click here.

Two years ago, in 2016, RK28 was observed with large mobbing wounds and abscesses on her back, the scars of which are still visible on her back. These wounds are caused by male monk seals and have been observed in other females. The Hawaiian Monk Seal Research Program reports this kind of male behavior can involve multiple males competing to mate with an adult female or a single male targeting a younger seal. To read more about adult male aggression, click here.

But back to some good news. Just two days ago, on June 30, RO28 provided the species with another member. This is RO28’s sixth pup in as many years on Kauai. Here is PK4 on the day of his/her birth. RO28 and pup day one

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.
