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.

Field Report: January 2012

A juvenile male seal (2-3 years old, about 200 pounds) was found dead on the northeast shore of Kauai on the evening of January 3, 2012. The seal was untagged, and believed to be a seal that volunteers have observed before. NOAA, DLNR/DAR and DoCARE responded on the scene.  NOAA’s Office of Law Enforcement was also engaged immediately, and is investigating this case.  The necropsy was conducted on the morning of January 4, and revealed that this was a suspicious death.  We cannot rule out foul play in this case.  Disclosing any additional information about this case could compromise the investigation.  Anyone having information related to any of the recent monk seal deaths should call 1-855-DLNR-TIP.  See our “News” section for details on the reward for more information.

RK13 (adult female, skin lesions since 2008, blind left eye, recent shark bites and canal-resting behavior) is doing really well; she is healed up and moving normally!

RK54 (juvenile male, born at Larsen’s in 2011 to RK22) hauled out in the Aliomanu area on 1/11 with a large ulua hook in the left side of his mouth, with a trailing leader and fish head attached.  We had a successful de-hooking, and a great training/learning experience for staff and volunteers.   RK54 was observed on 1/21 with blood on his nose/muzzle.   Possibilities include that (1) he was hooked again on the nose and removed the hook himself, (2) he had an infection or illness causing him to bleed from the nose, or (3) some other injury occurred to the area.  He has since been observed by volunteers and DLNR staff; his appearance and behavior have returned to normal, but we are still monitoring him closely.  What a month for this little guy!

RK56 (juvenile male, too curious about humans last Fall) has been frequently seen over the past few weeks at Kalapaki Bay.  Observers note that he has not sought out any human interaction, and it has been endearing to see how the local folks who regularly picnic in the area have taken to protecting him.

On 1/20, a memorial for male seal TT40 was led by one of Kauai’s kupuna at Maha’ulepu Beach, one of the seal’s regular haul-out locations.  It was a beautiful day.  The event was attended by several volunteers, NOAA staff, and a television film crew.   Kupuna  opened with a chant to clear the path for TT40, then the attendees spent some time individually remembering the interesting and enchanting seal that he was.  Kupuna shared another chant celebrating TT40’s long life, and all those

present had the opportunity to return some of his ashes to the ocean. The members of the film crew, from ABC’s “Born to Explore”, were very respectful and grateful to be able to share part of TT40’s story with the world.  This segment was one of many; the show will also highlight research and response efforts to conserve the Hawaiian monk seal.

Field Report: November/ December 2011

We have had several reports of seals swimming up into canals on the east shore over the past few weeks.  In particular, RK13 has been observed “logging” 
(resting at the surface of the water) in a canal near the Kapa’a Library.  Both 
freshwater activity (and the health hazards presented therein) and logging 
are behaviors of concern for Hawaiian monk seals.  Please be sure to report 
both immediately, so that our staff can respond and observe the behavior(s) 
in person.

RK13 is of special concern, and we are monitoring her very closely.  She 
has two new injuries (first observed 12/7), consistent with shark bites.  One is near her left 
foreflipper, which she did not appear to be using for the first couple of weeks.  The other is on the underside of her 
right side.   Neither wound is life-threatening, they are not very deep, 
and both are showing quite a bit of healing progress.   She began hauling out on sand again in Kapaa town on 
12/11, but has also continued to visit canals.  She rests peacefully in the Kapaa Library canal, but had a rough day in the canal near the Bull Shed 
restaurant on 12/13.  The canal was a couple of feet deep when she entered 
it early in the day, but by afternoon it was down to a few inches of water. 
RK13 galumphed all the way up the canal behind the Safeway shopping center, 
and struggled to get out of the sludgy mud.  It was awful to watch, but 
handling her would have been more stressful and likely less successful than 
letting her work her way through.  She did figure it out, and worked her way slowly (lots of rest breaks!) back to the ocean.  Since then, she has 
hauled out on sand in Kapaa, Anahola and Moloaa, and also spent a few 
more days in the Kapaa Library Canal.  She is using her left foreflipper normally 
again, starting on Christmas Eve!  Thanks for that holiday gift, RK13!

RK30 (adult female, entanglement scar around neck and large scar on side), 
interestingly enough, was observed in two different Kapaa canals on 
12/29.  Careful 
not to get these two ladies confused!

Another two seals who have flipped the switch on us are RK56 (weaner male, exhibiting curiosity toward humans in November) and RK52 (weaner female, 
born at Larsen’s, April 2011)!  RK56 was most recently seen today at Nukoli’i on the east shore, and RK52 has been observed twice in 
Hanalei.  Careful not to assume identity on these little seals – they’re on the move!  RK52 
has been hauling up very high and looking for trouble; last week she hauled out under a plastic chair, and the next day under a wire fence!  Thankfully, 
she was not entangled.

RB24 (subadult female who lost weight earlier this year) continues to look improved!  Her body condition is back to normal.

R313 (adult female, formerly Temp V23) received a new “V23” bleach mark 
while PIFSC’s Mark Sullivan was on island visiting.  Thanks, Mark!   R313 has been observed from Larsen’s to Ke’e.

At sunset on Christmas Eve, we received a report of a seal entangled in a net in the rocks behind the Beach House restaurant in Lawai.   The entanglement
turned out to be a false alarm; the juvenile tagged seal was just investigating the lay-gillnet in the water.   DoCARE reports that any net is illegal if it is either (1) left unattended, or (2) still set after sunset.  This net was both, so law enforcement is working to identify the net and remove it.

On 12/28, at sunset again, we had another report of a lay-gillnet set about 50 yards down the beach from a hauled-out seal, this time at Ke’e 
Beach.  One of our volunteers was present and spoke with the fishers, but they left the net in place.  Luckily, R313 (adult female bleached V23) did not get entangled. 
We saw her hauled out nearby the next day.

RA20 (juvenile female born at Larsen’s in 2009, a.k.a. “Momona”, rarely 
seen) has been observed on the south and east shores recently!  She is 
clearly not accustomed to being near humans; she is very sensitive, and was disturbed off of the Courtyard Marriott beach twice yesterday by beachgoers walking past her too closely.

A Hui Hou TT40

It saddens us to report that our oldest seal, TT40, passed away sometime between the evening of 11/10 and 0500 on 11/12.  TT40 was at least 27 years old, and provided amazing learning experiences for veterinarians, researchers, response staff and volunteers alike throughout his life. It’s likely that we have him to thank for quite a few of the younger generation of seals around here, too.  TT40 originated from Laysan island in the NWHI, and has been on Kauai since the mid-1990s.  In 2004, he swallowed a large hook and was transported to Oahu for successful surgery to remove the hook.  He lived through four sets of flipper tags!  He was a favorite of many.  TT40 has been showing his age for quite some time – you may recall that his molt started but never finished at the beginning of this year.    He was spotted by a fisher in the wee hours of the morning.

TT40

Special thanks to all of the volunteers and members of the public who helped to carry TT40 from the beach.  Thanks to our whole necropsy team too – our veterinarian, PIFSC scientist, PIRO response coordinators, and volunteers!  Finally, thanks to everyone who helped take care of TT40 throughout his long life.

We have not determined TT40′s cause of death, but it appeared to be a result of his age.  We may learn more from the pathology results.   He will be cremated and returned to the ocean.

RK54, the male weaned seal born at North Larsen’s in April of this year, had a plastic ring around his muzzle on October 11, preventing him from eating normally.   Our team was able to remove the ring and check the muzzle for injuries.  Thanks to our volunteers and members of the public who helped with this important response – go team!!

We have had several sightings of T21M, an adult male seal from

Laysan in the Northwestern Hawaiian Islands.  He was relocated to the main Hawaiian islands in 1994, and was recently flipper tagged 7GY/7GZ and fitted with a cell phone tag on Oahu.  He was most recently seen at Lawai Kai in the National Tropical Botanical Gardens!

RB14 (four-year-old female) and RA16 (two-year-old male) had a molting party on the east side again this year!  RA16 has now successfully molted.

RK56 (weaner male, born at Miloli’i in May 2011 to RK30) has been very curious with humans in shallow water for the past week at Ke’e Beach, at the end of the road on the north shore.  He has been observed following snorkelers, and checking out children face-to-face in the very shallow water.  This is dangerous behavior for RK56 and for the people near him.  As a newly weaned seal, he is curious and nonaggressive.  However, if humans reinforce this behavior (with food or play), he will begin to expect and demand the reinforcement, and could become aggressive to those who don’t behave the way he expects them to.  Also, as he grows, he will become larger and stronger; and hormonal changes will cause him to exhibit new behaviors that will certainly be dangerous to his human playmates. We would like to monitor RK56 very closely. If you see him please report it to our Kauai Monk Seal Sighting Hotline at 808-651-7668, keep your distance, and encourage others to do the same.

RK13 (flipper tags 5AA/5AB) is an adult female with a chronic lesion on her rump.  RK13 has had a “lump” since 2008, but it has recently swelled, likely become infected, burst, and begun to slough. We are prepared to send a team to sample and medicate her, but presently the lesion seems to be subsiding on its own.  This, combined with the possibility that she is pregnant, warrant the need to evaluate very carefully before handling her.   For now, we are closely monitoring the progress of the lesion.  If you see her, please report her to the hotline, photograph her full body and the lesion, and email photos the same day to 
kauaiseals@gmail.com.

UPDATE to Field Report: August/September 2011

Juvenile male seal RT12was seen on August 30 with a small hook in the skin of his belly, between his umbilicus and his

penile opening.  At that time, the hook had a red transparent lure and about 3 feet of fine monofilament attached.  He was observed a few days later with only a few inches of line remaining. He has now been seen several times with no hook or line!

Four-year-old female RB24 is showing marked improvement!  She was given an antibiotic injection on August 4, and her gradual weight-gain was almost immediately apparent.  It is unclear whether the de-worming, the antibiotics, or a natural recovery from her sudden decline is to credit for her improvement; but regardless, it’s a relief to see it!

Weaned seal RK56 (born in May to mom RK30) has been regularly seen between Ke’e and Ha’ena Beach Parks.  He finally made the trek from his natal beach, Miloli’i on the Napali Coast!  The two weaned seals born in April have also left their birthplace to explore nearby Aliomanu and Anahola.

Two of our 2011 mother seals, RK22 and RK30, successfully molted in August.  Hawaiian monk seals go through a “catastrophic molt” once per year, losing their entire outer layer of fur and skin.  This is a physically stressful time for the seals, and they often stay on the beach for up to a week during their molt.   Female seals molt as part of their reproductive cycle.  After weaning a pup, they “super-forage” to fatten back up, and then molt before mating and carrying the next year’s pup.

Field Report: July 2011

Sub-adult female RB24 continues to be of concern.  Her condition has neither visibly improved nor worsened.  On July 13, PIFSC scientists returned to Kauai to get a full suite of biomedical samples from her, and to change out her larger cell phone tag for a smaller satellite tag.  She was also given a de-worming medication to help maximize her nutrition intake by lessening her parasite load.  Great work by our east-side volunteer team, who collected a fecal sample from her the following week – this will allow us to see if the medication is working!

The same day, three-year old male RW02received a cell phone tag, so

that we can track his movements and dive behavior to better understand his habitat use.

Adult female R315 (formerly known as Temp 365, mother of RA16) has been seen at least twice recently, looking very pregnant!  Since she did not pup last year, her due date is anyone’s guess.  She has been spotted on the northeast shore, and previously pupped at Larsen’s, so we may very well be looking forward to another pup event there!

A new unknown subadult female seal was spotted in the Anahola area earlier this week with a mysterious mark on her belly.  We would very much like to lay eyes on this seal again, in person, to determine whether this is a natural mark, an injury, or a foreign body.  If you see her, please photograph and report her to our hotline (808-651-7668) right away, so that we can come to the site to observe her.
