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.

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.

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.

 

Seals Heal in Amazing Ways!

Adult female, RK13 was found on April 26 with a large wound to her face, with tears to the skin around her nose, leaving her left nostril (nare) no longer visible. Close inspection revealed a series of triangular cuts, indicating a shark bite. Seal wounds close up and fill in by a process called tissue granulation. 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! Our NOAA veterinarian was kept informed of the wounds and healing progress to determine if intervention was indicated. Though wildlife wounds often look disturbing, wild animal medicine demonstrates how resilient wild animals are.

More new seals for Kauai.

On March 28 a juvenile male seal was first sighted on the North Shore. His only remarkable scar was a small cookie cutter shark bite on his left mid side. He quickly became a regular, so a team was put together to tag him with flipper tags 3CD and 3CE, making his official ID R3CD. He also received a morbillivirus vaccine.

A new adult female seal with a small pit scar on her right mid side also started to appear on the rocks at Brenneke’s beach, and continues to rest there regularly. She was bleach marked V76, and received her first morbillivirus vaccination.

RG22 dehooked.

On April 16, visitors snorkeling at Mahaulepu called the hotline to report that they had cut free a seal entangled on coral. They sent a video that identified it as juvenile male, RG22. The next day, he was sighted at Palamas, so a team was assembled to respond. Fortunately, even sporting the biggest hook we’ve ever come across, the team was able to cut and remove the hook that pierced the left corner of his mouth. The fishing gear was a slide bait rig used for ulua fishing and included the bait that looked like a Hawaiian white eel or Conger eel, known locally as Tohei.

RH92 returns to Lihi Canal.

RH92 (Dennis Fujimoto)

PC: Fujimoto

After wildlife biologists and veterinarians relocated 10-month-old RH92 on March 30th from the Lihi Canal in Kapa‘a to a beach on the island’s west side, we’d hoped she would stay away from the canal. Unfortunately, she returned to the canal along with an adult seal (RK13). Together they’ve been seen feeding on small fish in the manmade waterway along with discarded fish parts. The return of RH92 to Lihi is prompting stepped-up public awareness and outreach and potentially enforcement of littering laws for fishermen who dispose of fish parts in the water.

Seals of concern.

RN02, subadult male, has demonstrated increased curiosity of people, pursuing swimmers and following the public up the beach. He is also interacting with scuba divers, taking fish from skin divers at Koloa Landing. He then hauled out on the boat ramp, undisturbed by divers walking past him to enter and exit the water. RN02 was displaced from the ramp using crowding boards. RN02’s curiosity also proved dangerous with marine debris, found around his neck, which he later escaped on his own. We hope this is just a part of reaching sexual maturity, but we are considering ways to curb his behaviors.

Another incident of concern made the evening news (click here) in which a dog owner should have moved away from the seal, but instead engaged the seal, and endangered both his pet dog (on a leash) and the seal.

Kauai Vaccinations have begun for 2017.

This year we will include females (except those within two months of pupping) in our morbillivirus vaccination program. This includes 18 males and 26 females. Coordinators will be busy trying to find these seals to give initial vaccines and boosters 3-5 weeks later, so we appreciate all your sightings!

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

One. On tax day, April 15, 2015, we welcomed our first Kauai pup of the year when RK13 gave birth to a big, healthy female. Volunteer Gary Langley reported the pup nursed several times during her first morning of life, and while still a few hours old, she took her first swim. All during PK1’s first week of life, the pair was visited by several males RK05, RV18 and a new-to-us monk seal, Temp 310, who chased all others the away. RK13 is an older, productive female that has only pupped once on Kauai. She usually pups on Ni’ihau.

Two. On May 15, 2015, we welcomed PK2 to Kauai, born to RK22, making this her fifth pup in five years. She’s sure turned into a good mother after a rough start in which she abandoned two pups two years in a row. But she can be a little wary, and as with all mothers in the animal kingdom, can be quite protective of her offspring. A few wildlife viewing measures are always important to keep in mind when near RK22 (and any other monk seals): Give them plenty of space; stay out of their line of sight; position yourself downwind; and camouflage yourself by staying low to the ground in and amongst bushes when possible. The goal is to watch without disturbing.

Three. On May 26, 2015, we welcomed PK3 to Kauai, born to RO28 who arrived from Oahu only days before. This young mother was born on Kauai but likes to spend her adult days on Oahu–until it’s time to pup. Then, she returns to her natal beach. Like RK22, this mother is very protective and has been aggressive towards people approaching her on the beach or in the water, so we request people give her a wide berth. Amazingly, volunteer Julie Honnert was on the beach with her video camera running when the big event happened. Check out this amazing video!

So, three, so far. And we expect more. Stay tuned. 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: Spring 2013

It’s Hawaiian monk seal pupping season!

Pupping season on Kauai has arrived with the first pup born to R028!  This 7 year old female, who spends most of her time on Oahu, recently returned to Kauai and delivered a healthy male seal pup on May 11th.  Generally, Hawaiian monk seals are known to return to their natal beach to have their pups.  In this case, RO28 was born on Kauai to RK06 in 2006 and is now a first time mom.  We are predicting several more pups on Kauai and as of May 22nd, 11 pups have been born in the Main Hawaiian Islands in 2013.

With pupping season in full swing, we are in need of new volunteers to assist with pup-sitting in addition to our regular duties of responding to seal haul-outs and strandings.  If you are interested, or know of other people that may be able to assist as volunteers, please let us know!!  Please call us at the Kauai Monk Seal Hotline (808) 651-7668 or email us at kauaiseals@gmail.org.

Hooked seal reports have continued on Kauai, with 6 successful de-hookings already this year.  RK13 was recently hooked as seen in this photo.  Kauai Marine Mammal Response Network staff and volunteers were able to cut free 50 feet of heavy monofilament line that posed an entanglement risk leaving the non-lethal hook lodged in the corner of her mouth.  Meanwhile, an Oahu de-hooking team was making preparations for a trip to Kauai, however, fortuitously RK13 dislodged the ulua circle hook on her own.

If you see a seal on a beach, please look closely for fishing line in or around the mouth and of course for hooks.  As always, please use binoculars and do not disturb the seal.  Often the hook is inside the oral cavity and the only evidence is a small amount of monofilament fishing line trailing from the mouth.  If you suspect the presence of a hook or line, please take photos and email them to kauaiseals@gmail.com.

Recently, the New York Times Magazine ran a front-page feature article about Hawaiian monk seals, it’s a must read.  Here’s the link:

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.
