In November, the Kauai team logged 239 seal sightings. This included 35 individually identified seals. Here’s a look at how the 239 number compares to other months.

November: 239
October: 225
September: 354
August: 236
July: 335

As a reminder, there are numerous reasons that can effect the number of reported seal sightings. Two big ones are the availability of our steadfast volunteers taking their daily beach walks, and the presence of moms with pups and the subsequent “pup sitting” we do. Of course, the seals themselves play a factor in this, too. Maybe there’s some seasonality in foraging that takes them to remote areas of the island where we don’t see them. That’s the thing with animals that spend the majority of their lives at sea–we don’t quite know.

Other November news to note:

  • Seal activity continues around Poipu Beach Park with seals swimming among swimmers, snorkelers and the water aerobics class and hauling out on the beach amidst beach-goers. Our advice continues to be for everyone involved to give the animal its space and never approach, touch, harass, disturb it. Remember: Monk seals are wild animals; let’s keep them that way.
  • One additional monk seal received its morbillivirus vaccination in November. This virus, similar to distemper in dogs, has not infected the monk seal species. But in a proactive effort to combat an outbreak, the Hawaiian Monk Seal Science Program started vaccinating seals last year. To learn more about the threat of morbillivirus, read this Smithsonian article.
  • Two seals “bleach-marked” this month–RG22 as V22 and R340 as V77. To learn more about using Clairol to help identify individuals seals, read this previous #MonkSealMonday report.
  • Four seals completed their molts in November, including: RH38, RG58, RK14, RH80. To learn more about molting in Hawaiian monk seals, read this previous #MonkSealMonday report.

RH38 is back and looking fit!

After 84 days in rehab at Ke Kai Ola (also known as the “Monk Seal Hospital”) on Hawai‘i Island, the yearling monk seal gained nearly 100 pounds. That’s more than a pound a day.

Here’s a video of RH38 exiting her carrier upon her return to Kaua‘i.

And here she is entering the ocean.

When we think of threats to Hawaiian monk seals, we often think of entanglements with marine debris. We think of monk seals ingesting fishhooks. These are the more obvious threats. That is, the ones we can easily see. But there are other threats that require the aid of microscopes to see, and that’s exactly what RH38 was fighting.

Gastrointestinal parasites (tapeworms) are not uncommon in monk seals; however, RH38 was carrying such a heavy load, it had a negative effect on her health.

RH38 was born to RK30 in the spring of 2016 at a remote beach along Napali Coast. At weaning, she was reported to be one of the largest pups of the 2016 season across the state. However, in the ensuing months, as you can see from the photos above, she lost quite a bit of weight. At her release from Ke Kai Ola last week, she topped out at a healthy 185 pounds. What’s more, she’d been de-wormed. She’s now in the perfect condition to go through her first annual molt, which, by the looks of all the green algae growing on her, is likely to happen soon.

When monk seals molt, they do so all at one time, over the course of 10 days to two weeks, spending much of that time conserving energy on the beach.

Since RH38’s about to experience her first molt, she was not outfitted with a telemetry tag that would tell us her whereabouts, because it would simply fall off as soon as the patch of hair and skin holding it in place does.

Ke Kai Ola was recently recognized by NOAA with a “Species in the Spotlight Hero Award” during the “Year of the Monk Seal” for their conservation efforts in helping recover the endangered Hawaiian monk seal. Since the hospital opened three years ago, Ke Kai Ola has rehabilitated and released 20 monk seals back into the wild. We are very grateful for their assistance in helping RH38 return to tip-top shape.

As well, we couldn’t move ailing monk seals quickly from Kaua‘i to Hawai‘i Island without the help of the U.S. Coast Guard who, once again, provided a lift for RH38. That’s two airplane flights for this one-and-a-half-year-old monk seal.

Last week, on a sunny day, our second pup of the year graduated to “weaner” status and was tagged RJ36. After about six weeks of dedicated nursing, RJ36’s mother, RK30, weaned him and headed back to the nourishing depths of the ocean to replenish the approximate one-third body weight she lost during the nearly six weeks she nursed RJ36 to a healthy weaner weight in the neighborhood of 175 pounds.

While the procedure to tag monk seal weaners only takes about five minutes, the effort to tag this pup took much longer–all due to the remote location of where RK30 chose to birth.

For years now, the Kauai Hawaiian Monk Seal Hui has been aided when accessing remote beaches by marine biologist Captain Tara Leota, sole owner-operator of Kauai Sea Rider Adventures. Captain Tara leads small groups of ecologically-minded guests on snorkeling adventures around Kauai. Captain Tara, her crew, and her guests welcomed our tagging team aboard her 25-foot rigid inflatable boat for the adventurous journey to find RJ36.

Currently, the way we track matriarchal lineage of monk seals is by visual observations of mothers and pups. As such, our goal is always to tag pups within days of their weaning. Once weaners start exploring other parts of the island and mixing with other monk seals, we cannot be sure of their lineage. Thus, Captain Tara has likely helped us know with surety the matriarchal lines of six or eight monk seals over the years. That’s a great effort.

It’s a pup!

Kauai’s first pup of the year was born one week ago today to RK22, who surprised us by pupping earlier than we anticipated. What’s more, she pupped on the same day as last year. Her pup goes by “PK1” until it will be banded after mom weans it in a few weeks.

PK1 has spent the last week learning how to nurse and swim–but sticking close to mom. Those two activities along with sleeping make up the little pup’s days.

RH92 (formerly known as PK2) has been busy. She now has a bleach mark of V92 that will make identifying her from a distance much easier. She’s also beginning to travel up and down the coast, going several miles one direction and equally far in the other direction. This makes her much harder for our volunteers to find! She’s been observed flipping rocks and checking things out just like a wild seal should. She’s also been observed with sea cucumber slime on her face. Not something that likely will continue as she discovers more deletable tidbits from the sea!

On day two of PK2’s life, the busy young seal was observed galumphing around its mother and nursing seven times throughout the day. Two males cruised by the pupping site but did not disturb mother (RK22) and pup.

We are proud to announce that we have another pup. Fifteen-year-old RH58 arrived from Oahu on Sunday, July 12th. In the midst of stormy weather, on Monday morning, she was found concealed in naupaka bushes with a nice healthy pup–that has since been confirmed male. This is RH58’s ninth pup born on Kauai since 2006. While she has spent her adult life foraging the waters around and hauling out on the beaches of Oahu, like many monk seals, RH58 returns to her own natal beach to birth, as well.

Our third pup born to RO28 has weaned, and his mother returned to Oahu a few days later, accompanied by an untagged male seal, Temp 319. This third weaned pup is tagged G28/G29 and goes by the ID name of RG28. When hauled out, he likes to hang out in rocks. These weaned pups seek rocks and objects to nestle against, possibly missing mom, and are vulnerable to people and loose dogs. They are very naive and curious, as all young are when they are learning about their environment and how to feed and socialize. Unfortunately their “cuteness” gets them in trouble when people approach them, try to pet or swim with them, and–most dangerous for taming a wild animal–try to feed them.
