New:

  • A second pup was born at a remote beach along Na Pali Coast. The ID of the mother is unknown, but likely the same Niihau female that has pupped on that beach the past two Septembers, R400. Tour boats and kayak companies are providing updates.

Updates:

  • Sub-adult female R7AA was seen with small lump under left jaw line on 8/31/19, possibly a small abscess. The seal has not been re-sighted since. The plan is to closely monitor.
  • RH58 (Rocky) successfully weaned her female pup, PK5. The pup was flipper-tagged and vaccinated and now has an ID of RL58.
  • RK30 successfully weaned her female pup, PK6. The pup was flipper-tagged, and the seal’s ID is now RL30.
  • RH38, the seal rehabbed at Ke Kai Ola and released in July, continues to thrive on the north shore.
  • The first three 2019 pups (RL08, RL52, and RL28) continue to be sighted in good condition at various north and east shore beaches.
  • Displacements: No seals were displaced this month.
  • Molting: Four seals were observed molting this month.
  • Vaccinations: PK4 and PK5 were vaccinated during pup tagging and received booster vaccinations three weeks later.
  • Bleach marking: One seal was bleach marked this month.

Research/Support of Pacific Islands Fisheries Science Center:

  • Sub-sampled scat, molt, and tissue plug samples accordingly.
  • Logged all seal sightings for PIFSC database. Organized photos and reported sightings, molt tallies, survival factors to send to PIFSC.

After a lengthy 53 (possibly 55) days, RK30 weaned her pup, and PK3 is now officially RL30. At tagging, she (yes, female) measured 126 centimeters from the tip of her nose to the tip of her tail and measured 104 centimeters at her plumpest just below her fore flippers.

This is RK30’s 11th known pup and her longest known nursing period. Conservatively, she nursed for 53 days; however, she may have nursed for as long as 55. The exact date isn’t quite exact, because RK30 pupped on a remote beach and daily reports aren’t always daily. Prior to this year, RK30’s longest known nursing duration was 51 days (RJ36) in 2017 and her shortest known nursing bout was 46 days (RL24) in 2012.

RK30 is something of a poster-seal illustrating the kinds of threats these animals face. Her story of perseverance can be read here.

If you’re keeping count, Kauai’s mamas produced a total of three females and two males this year. In 2019, three regulars birthed and raised pups on Kauai–RK30, RK28, and RH58. After previously pupping on Maui and Lanai, RB00 pupped for the first time on Kauai, her birth island. And after giving birth to a stillborn pup last year, RK52 produced a healthy pup this year.

Updates:

  • RH38, the seal rehabbed at KKO and released in July continues to thrive on north shore.
  • The first two 2019 pups, RL08 and RL52, continue to be sighted in good condition at various north and east shore beaches.
  • The last two North Shore pups weaned in August and were tagged. These pups are both female and born to RK28 and RH58 (Rocky), both common Oahu adult females. Extensive pup-watch monitoring took place in August with very few issues.
  • Sightings of the remote Napali pup of RK30 continue to come in from tourboat and kayak tours on the Na Pali Coast. The pup weaned in the last week of August.
  • Displacements: R7AA was displaced away from the road edge at Lawai Beach.
  • Molting: 3 seals were observed molting this month.
  • Vaccinations: PK4 and PK5 were vaccinated during pup tagging.

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.

On two consecutive days in July, two female Hawaiian monk seals hauled out onto the beach with heavy bellies and gave birth to pups. Since then, both pups have progressed as expected–nursing and gaining weight, losing their fetal folds; swimming in short bursts in shallow waters, then progressing to deeper water and longer swims. Now, pups are starting to molt their lanugo coats; as typical, most notably in their faces. There’s been no official confirmation of gender yet; however, typically, it takes longer to positively identify females. In the case of endangered Hawaiian monk seals, the more females, the better, so delays of this kind tend to bode well.

What follows are slide shows of PK4 and PK5. Both sets of photos were taken on August 12th. (FYI: Because PK3 was born  in a remote location, we do not have regular photo updates.)

Here’s RK28 and PK4, who was born on July 19th.

And here’s RH58 (Rocky) and PK5, who was born one day later on July 20th.

Field Report: July 2019

The Kauai team logged 239 seal sightings this month. This included 28 individually identified seals.

July: 239
June: 179
May: 262
April: 348
March: 350

Jan: 284

New:

  • RK30 gave birth to PK3 on July 10 at a remote site along Na Pali coast that is accessible only by water. Kayak Kauai took signs out to post in key areas nearby.
  • RK28 gave birth to PK4 on July 19 at another remote location. Pup is thriving. Two stray German Shepherds were captured running loose near the newborn pup, on the day of birth and while RH58 was in labor.
  • RH58 gave birth to PK5 on July 20 just down the coast from RK28. With permission from NOAA, the Kauai team had to intervene and cut the umbilical cord to remove the placenta, which was still attached more than nine hours after birth.

Updates:

  • RH38 was released on July 22 after transport from Ke Kai Ola aboard a USCG C-130. Since then, she’s ranged across the North Shore and the Na Pali coast in the weeks following release and has showed no signs of interest in people on the beach or in the water.
  • The first two 2019 pups, RL08 and RL52, continue to thrive and range farther from their natal sites.
  • Displacements: 2 displacements occurred this month. Both were to remove S/F R7AA from the road edge. She was displaced a third time on Aug 1 from the Lawai Beach road edge as well.
  • Molting: 3 seals were observed molting this month.
  • Vaccinations: None given this month.

Predicting delivery dates of babies is hard. Without the aid of physical examinations and sonograms, it’s even harder to predict the birth dates of Hawaiian monk seals. And yet NOAA has gotten pretty darn good at it.

RK28 was expected to give birth around July 13th. She pupped on July 19th. (Note the “milk nose.” That’s one of the indicators that a pup has figured out how to nurse.)

On the same day PK4 was born, two loose dogs were reported romping in the surf just down the beach from RK28 and pup. Thankfully, friendly people on the beach caught the dogs and prevented them from harming the seals. You may recall that RK28 lost a pup due to a dog(s) attack several years ago. You can read more about that tragedy here. So, this is a good opportunity to remind people not to let their dogs roam free.

One day later, RH58 gave birth to PK5.

RH58’s due date was predicted as August 1st, give or take. Instead, she pupped on July 20th. This was particularly challenging due date to estimate, since RH58, also known as Rocky, pre-weaned her pup last year after several pup-switches. You can read more about that here. But as these photos show, Rocky and pup are doing well and bonding nicely.
