Update: RH38

In our recent “Field Report, we shared that RH38, a yearling female, had been observed steadily losing weight over the summer. On August 11, she was transported by a US Coast Guard C-130 to Kona, where she is being rehabilitated at Ke Kai Ola, the Hawaiian monk seal hospital.

As you may recall, RH38 was born to RK30 last year, our first birth of 2016.

When RH38 was admitted to Ke Kai Ola, she weighed 88 pounds, about half her size at weaning a year prior. It’s not unusual for monk seal weaners to lose weight as they learn how to forage on their own, but, clearly, RH38’s weight had dropped more so than other yearlings her age. An exam performed at Ke Kai Ola revealed RH38 was carrying a heavy infestation of tapeworms. Intestinal parasites are not uncommon in monk seals, but have been documented to inhibit growth and even cause death in young Hawaiian monk seals. After treatment, RH38 is now eating well and gaining weight a good clip. She’s expected to be released from Ke Kai Ola’s care in the next couple months.

“This is why we built Ke Kai Ola,” said Dr. Shawn Johnson, Director of Veterinary Science at the Marine Mammal Center, on the Center’s website. “If we want to save this species, every monk seal female counts, so we’re proud to be able to provide long-term rehabilitative care to monk seals like RH38 and ensure they are able to survive and thrive in their ocean home.”

Because RH38 will be released back into the Main Hawaiian Island population, where there’s a good chance she may encounter humans, the staff at Ke Kai Ola is taking great precaution in treating RH38 so that she does not associate humans with food. We want all our monk seals to continue to be the wild animals they are.

We’ll continue to report on RH38’s progress, so check back periodically.

Field Report: September

V93 is now R7AA!

Dr.Barbieri-R7AA.(V93-BrendaBecker)P1020458

PC: B. Becker

A yearling female that showed up on our north shores in late June, made her way south in August. She hauled up several times at Lawai Beach where the NOAA Science Center scientists and veterinarian were able to capture and examine her healing abscess and, with the Kauai team, flipper tag her (7AA/7AB).

RH38: A female yearling seal that was underweight, was transported August 11 by US Coast Guard C-130 to Kona, where she is being rehabilitated at Ke Kai Ola, the Hawaiian monk seal hospital. Her admission weight was 40 kg and she was treated for tapeworms, which were causing her to do poorly. She is eating well, and now is at 46 kg. She has two companions from the NWHI, one admitted in June and the other in August. The plan is to complete her treatment for tapeworms and to allow her to gain enough weight to insure her success after release in another month or two.

Hooked Seals
hooked-seal-image000001-2.jpgThe adult male seal that was hooked in his back threw off the hook, and continues to be seen at Poipu, he is now freshly molted and known as Temp331.

An unknown seal was reported by a fisherman on the rocks at Kaumakani point last week. The hook is in the right corner of the mouth and is non-life threatening. We do not know of the identification of this seal, whether it has tags or its sex. It may be a young adult or subadult, possibly a Ni’ihau seal, so keep a lookout!

Seal Research

P1020314 (1)

PC: B. Becker

The NOAA Pacific Islands Science Center research biologists were on Kauai for a week working with the Kauai team to find a subadult or adult male seal to deploy a new streamlined “critter” camera. Searching all coasts, practically all of Kauai’s seals were sighted! Many of the mature males were either starting or finishing their molts, so they were not candidates.

PC: B. Becker

Finally R1KT (molts in Dec.) was found on a quiet sandy beach. The team was able to capture him and place a camera (in front) and cell phone transmitter to help relocate him to remove the camera three days later to retrieve the footage. The instruments not only gave a visual video record of movements, but also location, depth of dives, time periods and speed! We look forward to learning what R1KT has to teach us!

We thank the many volunteers that searched with us and responded to mul- tiple seal haul outs to find a good candi- date. We also found a new large adult male, fairly clean, without scars, not known to our records. With additional experienced seal handlers, we were able to capture this seal and tag him. He is now called R2XS with tags (2XS/2XR).

Famous Waikiki Pup Translocated
RH58’s weaned pup, is now known by her tags at RJ58 and still remembered as Kaimana, the Ha- waiian name for her natal beach. Because of vari- ous risk assessments and considerations, she was translocated to a north shore beach to put her in a safe location, where she could interact with other seals and safely forage and explore without the human crowds and dangers at Waikiki.

Also the whole story written by a NOAA biologist can be found here.

Additional Marine Animal News
The State Board of Land and Natural Resources Approves New Boating Rules that will prohibit feeding of wildlife or feral animals, and abandoning animals, and creating or contributing to colonies at any property under the boating division’s jurisdiction. These new sections were added in response to complaints about increased feeding of feral animals at boating facilities, which creates potentially unsafe and unsanitary conditions and endangers sea life.

The board approved both amended rules but deferred implementation of a provision that would allow disposal of feral or abandoned animals at state small-boat harbors until Jan. 1, 2019. The delay was to give time for the boating division to work with animal caregivers to come up with a viable plan to relocate colonies of feral and abandoned animals to areas outside of the small-boat harbors.

NOTE: Cats are the only reproductive host of the parasite toxoplasmosis, which has killed monk seals, and continues to threaten human and other marine mammal health. Click here.

Field Report: Summer

2017 pups are all weaned and tagged!

Monk Seal Pup RJ22-2All 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.

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.

Field Report: Winter 2017

The winter of 2017 has turned out to be busy for the Kauai HMS Conservation Hui.

RICOH IMAGING

In January a new juvenile female seal was sighted. She has what appears to be a healed cookie cutter shark bite behind her left eye. She also has a pit scar on her right mid side. She was originally sighted on Ni’ihau and is officially R347.

In February five more juvenile female seals were sighted. Four of them were bleach marked and/or flipper tagged, so we can track and monitor them, especially since several of them are fairly clean of scars or natural bleach marks can often be used to identify untagged seals.

One with a faint scar behind her left eye was entered into the monk seal registry as R351 and bleach marked V73. A week later, using her bleach mark to identify her, she turned up on Molokai.

A youngish female popped up on the east shore several times, with a distinguishable natural bleach mark on the tips of her left fore flipper. She was flipper tagged and is now 1NS.

On the west shore, a juvenile female was bleached V75 and flipper tagged as 1KM.

Two more female yearlings were found on the west shore, one of which was bleached as V2.

In February, RN02, a subadult male who was translocated from Big Island to Niihau in 2013 after he repeatedly interacted aggressively with swimmers, was sighted with blood near his mouth. A visual examination revealed a small hook and approximately six inches of monofilament fishing line along his gum line. Consultation was made with a marine mammal vet, and it was determined the hook would likely loosen and fall out on its own. Thus, no intervention was deemed necessary at the time.

Sadly, a well-known Kauai seal was found dead in late February. R4DP, a female, was approximately 15 years old. She was first tagged on Kauai in 2008. That same year she was flown to Oahu for examination for suspected ingestion of a fish hook. Upon examination, no hook was found, and she was returned to Kauai and released. Unfortunately, after necropsy, it was determined R4DP’s injuries were inconsistent with natural causes. Thus, as a marine mammal protected by the Endangered Species Act, her death is being investigated by law enforcement officials.

This is the 11th “suspicious death” of a monk seal since 2009, and the first since 2014.  Anyone having information related to the death of R4DP or any other suspected monk seal death should call the NOAA OLE hotline at 1-800-853-1964 or DLNR Division of Conservation and Resources Enforcement (DOCARE) at (808) 873-3990 or 643-DLNR.

2016 Pup Update:

Weaned pup updates RH80 continues to appear on the north and east coasts of Kauai, looking healthy. Also, for the first time since she was flipper tagged last summer, RH38 popped up on the North Shore, also looking healthy.

RH92 is looking good, too, although she turned up with a cookie cutter shark bite on the right side of her head. Though it is the usual 3” circular wound, it appears very large on her small head and looks deep. Fortunately the bite missed vital structures of her eye and ear. Monk seals have an amazing capacity to heal from large wounds on their own. RH92 is healing fine, and the wound will likely shrink to a small pit scar. Of greater concern for RH92 is that she was found for the first time hanging out near a small boat landing, foraging and eating a fish, likely scraps tossed out by fishermen. This is a good reminder not to throw fish and scraps into the water, especially if a seal is present.

Field Report: June

Updates for our Kauai seals and pups.

RK30 weaned her pup, PK1. This pup most likely nursed 49 to 50 days, making this a very big pup. On Monday, June 27th, she was tagged and vaccinated and is now, officially, RH38, (tags H38/ H39).

Vaccinating seals on Kauai.

The Kauai coordinators are in the process of vaccinating Kauai seals against Morbillivirus, a disease that causes measles in humans and distemper in dogs. To protect our rare Hawaiian monk seals, the first ever vaccination of wild seals has been initiated, as epidemics of this deadly virus have devastated other seal species populations around the world. So far, 13 Kauai seals have received their initial vaccination and some their second booster shot. We are now earnestly looking to booster several male seals, and volunteers can assist us by looking out for RF28 ( red tags, and transmitter on his back, on the north and east sides of Kauai), and N1AA (black tags on the south and west sides of the island). Also, RN30, R8HY subadult males found primarily on the east side often Ahukini cove.
Here is a video of how seals are vaccinated. We will put out a list as time goes on, to identify which seals we are looking for to booster in the 3-5 week window and would truly appreciate assistance in looking for them.

RF28 and RF30 released and doing well.

On May 27, RF28, a juvenile male seal, was found with an ingested hook that was successfully removed on Oahu by a veterinary team. He was soon released back on Kauai with a transmitter on June 2.

Dive data RF28

A week later, we were surprised to find another internally hooked seal, RF30, a juvenile female! She was located at the Poipu county beach park keiki pool where she was logging and acting strangely. A team was assembled for a water capture using fence panels and crowding boards. This challenging capture was successful due to our many fine volunteers that rallied on a very short notice. Without volunteers to find and assist with capturing these injured seals, none of these successes would be possible! We supremely need and appreciate all our volunteers! RF30 was also transported to Oahu by a US Coast Guard C-130. She was found to have some swelling in the throat where the hook was lodged and at the base of the tongue. It was successfully removed using an endoscope and specially designed tools. Four days later RF30 was flown back to Kauai and released on the east side of the island where she normally resides. Both seals are fitted with satellite tags that are solar powered.

Other marine species:
News from NOAA Fisheries Sea turtle program. If you see a honu or ‘ea on the beach or in the water, please remember:

  • View sea turtles from a distance of 10 feet (3 meters). In Hawai‘i, we view turtles respect- fully. Give turtles space and don’t feed, chase, or touch them.
    Hawaiian honu bask on the beach. This is normal behavior. Don’t try to
    push them back into the water.
  • “It’s OK to help!” Fishermen, check your gear often, use barbless circle hooks and adhere to state gillnet rules. If safe for both you and the turtle, release accidentally caught turtles by fol- lowing these steps:
  1. REEL-IN the turtle carefully
  2. HOLD by its shell or flippers
  3. CUT LINE as close to the hook as possible, and
  4. RELEASE with no (or as little) gear or line attached.
  • “No white light at night.” Use wildlife friendly lighting near the coast (yellow/amber and shielded lights). Don’t use flash photography, and keep lights and beach fires to a minimum from May to December, when turtles are nesting hatchlings are emerging.
  • Avoid beach driving. Off-road vehicles crush nests, create tire ruts that trap hatchlings, and degrade habitats. Driving on the beach is also illegal in most areas.
    Prevent debris and rubbish from entering the ocean. Participate in beach and reef cleanup activities.
  • Report all hawksbill sea turtle sightings, any nesting activity (turtle tracks or nest digging), and injured or dead turtles to NOAA’s Sea Turtle Stranding Hotline on Kaua‘i: (808) 274-3344.
  • Report illegal or suspicious activity that may result in turtle injury or death by calling the Division of Conservation and Resources Enforcement (DOCARE) at
    (808) 587-0077 or 643-DLNR.
