What’s better than one pup? It’s two! The day after RK22 gave birth, another reliable mother, RK30 also pupped. This one, we know, is a male. Here are a few pictures of the one-week-old pup, known as PK2.

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.

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.

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.

First Kaua`i Pup of 2016

First Kaua‘i Pup of 2016

On April 26, a video showed a seal at Salt Ponds County Beach Park being harassed by a man. The seal was reported as RK30, a 17-year-old female and pregnant at the time. The video went viral, and a 19-year-old man was arrested within a few days by Hawai‘i State DLNR officers and NOAA Law Enforcement. Story here and video here.

The good news is that less than a week later, RK30 gave birth to her seventh pup. Story here.

We expect more to be born on Kauai, so be on the look out for any small black pups! Here is our schedule of expected births:

  • RK13 Due possibly any day, though her pregnancy is unsure.
  • RK22 Due at the end of May
  • RO28 Due June 10
  • RH58 Due July 28
  • RK14 Pupped early July 2015, usually pups on Ni’ihau
  • R313 Not sure when she pupped 2015, usually pups on Ni’ihau
  • RK28 Likely pupped June 2015 on Ni’ihau

2012 Year in Review: 2,556 individual seal sightings were reported in 2012 (many of the same animals on different days of course), or an average of 7 seals per day!  This was only possible due to the incredible efforts of the volunteer network.  The Kauai Monk Seal Conservation Hui identified 45 different seals on the beaches of Kauai during 2012, including 4 pups that were born on the beaches of Kauai in 2012.


Pupping Predictions for 2013!  Here are the predictions for 2013 provided by the Pacific Islands Fisheries Science Center staff.  There were several regular ‘moms’ that skipped 2012 (R015, R305, RY30, RS00, R006) so they can pup anytime and likely will pup earlier in the year rather than later. We could also be seeing some first time moms this year.

Pacific Island Fisheries Science Center (PIFSC) Research on Kauai:

instrumented-sealThe Pacific Island Fisheries Science Center (PIFSC) joined the Kauai crew in January for field work that included flipper tagging TempV19 (juvenile male) who is now tagged 8HY on the left rear flipper and 8HZ on right flipper.  His official ID is now R8HY.  Also, RW02 (adult male) was instrumented with a National Geographic Critter Cam which recorded 5 days of foraging and diving behavior (see photo below).  Click on this link to learn more about this program.

Stranding Responses to Hooked Seals:

As some of you may have heard, two seals were hooked with Ulua circle hooks in Hawaiian waters during February, one was a juvenile male RT12 here on Kauai.

RT12 was successfully de-hooked twice and released back in the wild.  Here is how it played out.  Thanks to an early report from one of our lead volunteers, we found RT12 hauled out with a circle hook in his mouth and 8 feet of fishing line trailing from it.  A team was immediately dispatched and RT12 was captured and hook removal attempted, however the hook went through the bottom side of the tongue with the barb imbedded in it.  This made either sedation or surgery necessary, therefore we loaded RT12 into a transport cage, brought him to Lihue where he spent the night at the baseyard until a veterinary team arrived from Oahu the next morning.  After sedating RT12, we found that the hook had now gone all the way through the tongue and into the left cheek.  The hook was cut in half, and easily backed out of the tongue and cheek.  The damaged tissue was swollen and slightly infected, but in good condition. It appeared that the hook was in his tongue for 24 to 36 hours, we were very fortunate to catch it so soon.

A satellite tracking tag was attached to track his dive behavior and movement.  RT12 was also given an antibiotic injection and then released.  Another lead volunteer sighted him sleeping comfortably on the rocks just south of the release location later that day.

hooked-t12To our great surprise, one week later, RT12 was discovered with another hook in his mouth!   A volunteer reported seeing 4-5’ of fine monofilament line coming from the mouth of RT12 again! Can you find the fishing line??

With the excellent assistance of many volunteers, the coordinators were authorized to mobilize an assessment team and equipment to capture, restrain, dehook and potentially transport the seal. Once we caught RT12, we found and removed one ”J” hook from his left front flipper. Unfortunately when we examined his mouth we discovered the additional line coming from his mouth with the hook out of sight, requiring sedation and surgical intervention to remove it.

Once more, RT12 was loaded into the transport cage to be watched overnight at the DLNR baseyard by the coordinators.  On the morning of Feb. 13, Dr. Michelle Barbieri arrived from Oahu and helped us transport RT12 to a local Veterinary Clinic on Kauai.  Under general anesthesia, radiographs revealed another one inch “J” hook in the esophagus.  With an endoscope, special instruments, and the expertise of two veterinarians, the hook was removed and RT12 was given antibiotics and his right rear flipper tagged T43 (he lost his T13 last year).  An hour later, RT12 was released again.

We are all very happy that this seal was discovered early and his ingested hook was removed, may he never again swallow another hook!  It is with much appreciation, that we thank all who work so hard to monitor and care for each of these endangered Hawaiian monk seals when they rest on our beaches.  It takes all of us working together for a bright future that we can share together.

hooked-seal-xrayThe other hooking had a less fortunate ending.  A juvenile male, RK68, from the Big Island died from ingesting a circle hook.  The links below provide the details:

Annual Seal Molting:  Winter is the season that most male Hawaiian monk seal’s molt.  At this time their testosterone levels are low and mature males undergo their annual molt. Both the hair and the epidermis are sloughed and replaced in this “catastrophic molt” that is similar to elephant seals, but unlike all other seals.  In the Hawaiian monk seal the actual observed molting period is about 10 days when the seal is seen ashore before and after the hair-skin sloughing period. The actual physiological process is probably much longer, and is a metabolically demanding time requiring the seal to rest long periods on shore and fast, that is why it is important to allow monk seals to rest peacefully while molting.  Also, documenting the timing and duration of molt is a good indicator for a seal’s health.

In the last two months, mature male seals R018 and RK31 molted primarily on the south shore, and for several days together at Poipu Beach Park, requiring extensive volunteer efforts to monitor and protect these seals.  Much outreach and education happened as well, while many visitors standing downwind of the seal noticed the strong “stinky” smell, due to the molt!  We so appreciate all the many essential volunteers that assisted to adjust the seal protection zones (SPZ’s) as the seals moved from the vegetation early in the morning down to the wave wash to thermoregulate in the day’s heat and back up to the vegetation line to spend the night!

RK31 90% molted (Molt  is estimated by % of molted skin remaining. Molt starts from the face and belly where it is rubbed off first).  Notice also circular pink wound from a fresh cookie cutter shark bite over the left hip.

Many people notice that the Hawaiian monk seals are different colors.  Freshly molted seals are a silvery gray with a lighter gray ventrally.  Some seals may be stained red by red dirt, more often seen in young juveniles that haul out to rest and hide on dirt and rock beaches. With time pelage ages to darker brown and hues of green appear around the face and flippers due to algae growth!  See in the photo below three males of various ages that are different colors due to when they molted.  RV18 is an adult that molted March 2012, RW02 is a subadult that molted Sept. 2012, and R8HY is a juvenile that just molted Jan.2013.

Field Report: Summer 2012

All four of our 2012 pups are successfully weaned, tagged, exploring, and mingling with other seals!

Credit: Langley

In early July, RL10, the oldest of the four, was relocated from her birth site at Aliomanu Road to the more remote sands of Waipake Beach on the northeast shore. Conveniently, her new site was near the birth sites of the other three pups! The relocation was done for RL10’s safety; Aliomanu was a hazardous location for several reasons, the main ones being proximity to the road and high human use. Mahalo nui loa to our veterinarian for flying over from Oahu to assist with this effort; to our Kupuna for her prayers, chants and elbow grease; to our volunteers for helping to execute the relocation; to vacation renters and property managers for granting us access through their properties; and to assorted members of the public for their spontaneous help. It takes a village to move a seal!

RL10’s mom, RK13, continues to be of concern. We are glad to report that she successfully molted at Mahaulepu Beach and has put on quite a few pounds since weaning RL10, but she is still thin. Now that the stressful process of molting is behind her, we’re hoping that she will start to gain more weight.

RL14’s mom, RK22, has been spotted several times on Kauai since weaning him. Her weight looks very good, she is 100% molted, and she was recently attended by adult male RK36 (of hook-swallowing fame, and still sporting his cell and satellite tracking tags) in the Anahola area.

RH58’s female pup was weaned on June 26, after 38 days of nursing; and was flipper tagged L17/L16, making her permanent ID number RL17. RH58 (a.k.a. “Rocky”) has traveled back to Oahu, her usual stomping grounds.

RK30’s male pup was weaned on July 10, after 45 days of nursing; and was flipper tagged L24/L25; giving him the permanent ID number RL24. Mom RK30 is in excellent condition and looks like she will begin her molt very soon. She was most recently observed at Salt Pond Beach Park, and was recently attended by Oahu adult male RO20 (a.k.a. “Kermit”.)

All four pups have still been observed in the Lepeuli/Waipake area, but the oldest three (RL10, RL14, and RL17) have occasionally left the area to explore new beaches to the north and south.

Juvenile female RK52 (“Rocky”’s 2011 pup) has spent most of the past year on the north shore between Ke’e and Tunnels, but has returned to her birthplace (Waipake) for her first molt. As of this writing, she is about 30% molted.

Juvenile male R6FQ began his molt several months ago, but has not completed it. Usually, monk seals only take about a week to lose their outer layer of fur and skin in their yearly “catastrophic” molt, but it’s not unheard of for a young animal to have a patchy molt like this. We are keeping a close eye on R6FQ (flipper tags 6FQ/6FO) to be sure his uneven molt is not a sign of a health concern.

It’s with sorrow that we report both the appearance and disappearance of a new seal to our island. Yearling male Temp V17 was first seen this summer on the east shore of Kauai, and given the bleach number “V17” by our DLNR specialist on June 15. On July 30, Temp V17 was found dead in the Wailua area. Local fishermen reported the carcass and graciously led us through blessings and prayers for the seal on the beach before we removed the carcass. Necropsy did not reveal a clear cause of death, but no evidence of human interaction was observed.

It’s PUP SEASON!  Kauai is now home to four new seals!

On April 23, RK13 surprised us by giving birth near Aliomanu Road in Anahola.  You may remember RK13 from previous reports of her canal-resting behavior last December and January.   She has previously given birth on the island of Ni’ihau (in 2008), but has never pupped on Kauai.  RK13’s pup is a healthy baby girl, who nursed for 31 days and now wears flipper tags L10/L11.  Her permanent ID number is RL10.

Later that week, on April 27, RK22 gave birth on the northeast shore to a healthy boy.  RK22 has been an unsuccessful mother in the past, abandoning at least two pups, but last year she did a great job with her male pup RK54, and this year she was a good mom again with new pup RL14.  He nursed for 34 days, and is sporting flipper tags L14/L15.

Regular Kauai mom RH58, nicknamed “Rocky” and usually dwelling on Oahu, gave birth to a healthy girl on May 19.  As of this writing, she is still with her pup, after five weeks of nursing.

Less than a week later, regular Miloli’i mom RK30(identified by her extensive scarring around her neck and left side) gave birth to a little boy on Kauai’s northeast shore on May 25.  RK30 is still with her pup, and they have been swimming around together.

It saddens us to report the death of three-year-old male seal RA16 on April 22.  He was nicknamed “Noho” for his tendency to stay close to “home,” first near his birth site and later in Kapaa town, where he was frequently observed at Kaiakea Cove.  RA16’s necropsy revealed another suspicious death, which is still under investigation.  Noho was cremated, and his ashes will be returned to the ocean near his “home.”

On May 8, adult male seal RK36 was observed resting in shallow water with fishing gear protruding from his mouth.  On May 9, our Kauai staff and volunteers were joined by a veterinary/science/management team from Oahu to respond.  RK36 was carefully corralled onto the beach and into a transport carrier.  He was driven to Lihue Airport, where a U.S. Coast Guard C-130 plane carried him to Oahu.  He spent a day resting at Waikiki Aquarium before being transported to Honolulu zoo for removal of the hook, which he had swallowed.  RK36 was in the best possible hands, with two internationally recognized veterinarians on his team.  X-rays showed the veterinary team the exact location and orientation of the hook, and they were able to remove it without surgery.   RK36 had an infection in the area of the hook (the left side of his throat), as well as pneumonia.  He spent 10 more days in recovery at the Waikiki Aquarium, where he eventually perked up and even ate some fish in his pool.  On May 21, he traveled back to Kauai and was released at Salt Ponds Beach Park, wearing two tracking tags (one that transmits a LOT of data to cell phone towers, and one that transmits less data to a satellite even when RK36 is out of “cell phone” range).  His tags showed us that he was travelling around the south and east shores of Kauai, and diving deep enough to show us that his lungs were fully functional.  He has been observed by volunteers and staff at Poipu Beach Park and Palama Beach since his release.  This was a true team effort!  RK36 wouldn’t have made it without the help of the public (who reported the sighting), volunteers (who helped transport him on the Kauai end and helped care for him on the Oahu end), veterinarians, NOAA/DLNR staff, and the fantastic U.S. Coast Guard!

RK54 (juvenile male, flipper tag K54) showed continued facial swelling at the beginning of February, and DLNR staff was able to give him antibiotics on 2/11. He was not observed at all for some time after his injection, but has now been observed several times.  The swelling is still apparent, but much reduced. Photos are still critical to further health assessment, so please keep them coming!

RB24 (young adult female, flipper tags B24/B25) was 100% molted as of 2/24.

RK22 (RK54’s mom, flipper tags 6FD/6FH) has recently reappeared on Kauai in the Larsen’s area!  Perhaps she has returned to grace us with another pup in a few months!

RK30 (adult female with prominent entanglement scars) was observed “logging” (resting at the surface of the water) all day near the rocks at Ahukini Landing on 2/17.  This is somewhat unusual behavior, but RK30 has since been sighted several times, looking healthy and likely pregnant!

I am sorry to report that juvenile male seal RK56 (born to RK30 at Miloli’I, 5/12/11) was found dead at Maha’uelpu Beach on 3/5, amidst stormy, flash-flood conditions.  RK56 was recovered by DoCARE and NOAA staff, and shipped to Oahu that night for necropsy the next morning.

RK56 spent a lot of time during the past 3 months at Kalapaki Bay, near a local hangout called Pine Trees.  The uncles that picnic, drink and eat there every day took quite a liking to RK56, and became endearingly protective of him.   RK56 is also the little guy who was getting too curious around humans on the north shore in November 2011. We posted flyers about him, and filled out special observation logs to monitor his behavior.  I gave a presentation about him to the Hanalei to Haena Community Association.  Our north and east shore volunteers spent a LOT of hours intensively monitoring this seal.  On behalf of RK56, we thank the whole island of Kauai for the special care you showed to this little seal.  RK56 will be cremated, and his ashes returned to the ocean.

Adult male seals RV18 and RK31 are both freshly molted!

RT12 (juvenile male) was deliberately disturbed recently at Glass Beach by a man who pulled on his rear flippers. Thanks to the volunteer on-scene for the detailed incident report, which has been passed on to law enforcement.
