Another pup has graduated to “weaner-hood” and received her (yes, female) official flipper tags. Meet RL58. Her mom, the renowned RH58 (Rocky), nursed PK5 for 45 days.

At tagging, RL58 measured 118 cm long and 96 cm around (girth). She’s reportedly doing well, even holding her own with RN44 (male) who has been spotted wrestling and swimming with her. A feisty female is good;-)

Here are some photos of her post-tagging.

Every month, anywhere from 30 to 38 individual Hawaiian monk seals are reported to the Kauai Hawaiian Monk Seal Conservation Hui. But just who are these regulars? Here’s a look at the top ten most reported Hawaiian monk seal sightings on Kauai this year to date.

Keep in mind, many things affect this list. Monk seals often have favorite haul out locations. If a monk seal favors a location that happens to be easily accessible by humans, bingo, that seal will be reported more often to the hotline.

Then, of course, monk seal moms and their pups rack up a high number of reported sightings, because they stick to the same beach for weeks on end. As this list will also reveal, young monk seals–especially sub-adult males–are often sighted and reported, too.

  1. With 83 sightings, adult R7GM tops the list of most reported monk seal sightings on Kauai this year.  A female, it appears R7GM may be pregnant for the first time. If she pups on Kauai, her chances skyrocket for remaining at the top of this list for 2019.
  2. With 81 sightings, R3CX ranks second for the most reported monk seal sightings on Kauai. R3CX is a five-year-old male commonly seen roughhousing with other young males on Poipu Beach.
  3. With 65 sightings, RG58 ranks third for the most reported monk seal sightings on Kauai. RG58 is a four-year-old male who also prefers the busy beaches of Poipu. His mother is the renown RH58, also known as Rocky.
  4. With 56 sightings, RB00 ranks fourth for the most reported monk seal sightings on Kauai. The year’s first report of RB00 came two days before she gave birth. She nursed for 54 days and immediately left Kauai after weaning her pup. Recently, RB00 was sighted on Maui. RB00 also counts Rocky as her mother.
  5. With 53 sightings, RK52, yet another offspring of the prolific Rocky, ranks fifth on our list. She provided us with Kauai’s second pup of the year. She nursed for 36 days.
  6. With 53 sightings, RN44 ranks sixth for the most reported monk seal sightings on Kauai this year. He is a healthy six-year-old male, frequently sighted on his natal beach on the North Shore of the island. His mother is also Rocky.
  7. With 52 sightings, RL08 is the grandson of Rocky. He was born to RB00 earlier this year and nursed for a whopping 54 days.
  8. With 50 sightings, RK58 ranks eighth for the most reported monk seal sightings on Kauai this year. Another pup of Rocky’s, RK58 was abandoned by his mother in 2018 and spent several months in rehab at Ke Kai Ola before being released back on Kauai.
  9. With 41 sightings, RK30 ranks ninth for the most reported monk seal sightings on Kauai this year. RK30 is pushing 20 years of age. She’s also one of the most storied monk seals around, having survived many threats to her life. Read more about RK30 here.
  10. With 40 sightings, RG22 ranks tenth for the most reported monk seal sightings on Kauai this year. RG22 is another four-year-old male who loves to roughhouse with the boys at Poipu.

(P)update #41

It’s been a little over two weeks since RH92 was tagged. She has been busy exploring up and down the coastline near where she was born, and she’s been making a few friends, too–there’s Temp325, RN44, RN30, 3CU, RK05, RV18 and even recently de-hooked RF28 sporting a tracking device on his back. We have not witnessed her eat any sea cucumbers, as many weaners inevitably do, but she has tried seaweed. Basically, she’s just being a wild monk seal and doing a good job of it, at that.

Here are a few photos of her escapades.

RK22 and PK2 had a couple swims today that totaled over four hours and were interrupted for three feedings and a variety of company. In one photo below, you can see a turtle, RN44, RV18, mom and pup. 3CU was also in the area.

By now, PK2’s teeth have started to erupt through her gums. Monk seals have two pair of eight teeth each for a total of 32, just like humans.

Here’s PK3. No confirmed gender yet. Still learning how the body works!

Here’s a side by side look at the size comparison of PK22/mom and pup/PK2. Give pup another week or so, and her girth will be comparable to mom’s.

Today, three-year-old male RN44 hauled out near mom and pup. RN44 was born along this same stretch of beach to one of our more productive females–RH58, also known as Rocky.

2015 Recap

2015 Total Numbers for Kauai Marine Mammal Response Network

We tallied the efforts of our 100+ member volunteer network over the past year and are excited to share the numbers with all of you. The gradual increase in seal sightings and numbers clearly show that monk seals are doing well in the Main Hawaiian Islands. We want to emphasize that it is the efforts of our volunteers that make this possible!

 Grand sightings total: 3,321 (9.1/day) monk seal sightings on Kauai in 2015 (up from 2,516 in 2014 or 6.9 seals/day)!

  •   Kauai population: 53 unique individual seals sighted in 2015 (47 in 2014)
  •   Births: 4 seal pups born on Kauai. Two pregnant females likely pupped on Ni’ihau (RK14 and RK28 departed pregnant, returned thin)
  •  Mortalities: RF22 – died from propeller strike
  •   Ni’ihau Seals: sighted 14 new seals in 2015 likely from Ni’ihau
  •   Kauai team flipper tagged 5 of these new unknown juveniles
  •   Bleach marking effort: 22 bleach marks were applied

Stranding: 6 monk seal responses.

  •  R6AP – dewormed and examined, SAT tag showed seal moved to Ni’ihau
  •  RN44 – circle hook removed from cheek at Larsens Beach. Full recovery.
  •  RF22 – found dead, cause of death was propeller strike.
  •  RF28 – ingested a circle hook. Transported to Oahu for surgical removal, released at Waipake after successful hook removal.
  •  RF28 – follow-up capture/exam due to flipper lameness. Minor laceration discovered, seal fully recovered from hooking.
  •  N1AA – J hook removed on the beach at PMRF. Full recovery.

RN44 De-Hooked!

A two year old male, RN44, was discovered at Waipake on April 3 with a large ulua hook in his left cheek. A heavy monofilament leader with swivel was attached to the hook and extended 18″ outside RN44’s body. Unfortunately, RN44 was resting on a large lava bench where he could not be safely captured, so we had to wait until he hauled up in a safe location.

RN44 was re-sighted on April 8. He attempted to haul-out several times along Waipake Beach, however the leader kept getting caught under his body and pulling on the hook, creating obvious discomfort. This action prevented him from hauling-out.

He was more successful on the morning of April 10, where RN44 was found sleeping several feet above the wave wash at the south end of Lepeuli Beach. A visual examination revealed the hook’s barb had pierced his cheek. A team assembled, safely caught him, and using a bolt cutters, successfully removed the hook and leader.
