Monk Seal Monday #116: Top Ten

Below you’ll find the top ten “reported” Hawaiian monk seals on Kauai for 2020. By reported, we mean those monk seals that were called in—and identified—to the Hawaiian Monk Seal Conservation Hui hotline. (See a monk seal on the beach? Report it to 808-651-7668.)

Keep in mind, many things affect this list. Monk seals often have favorite locations where they haul out. 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. 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. Molting monk seals, too. As this list will also reveal, young monk seals are often sighted and reported, too, because they tend to make themselves noticed;-)

To make this list a little more interesting, we’ve included only those tagged seals, meaning pups are not included until they are weaned and flipper-tagged.

You might find it interesting to compare this year to last year. You’ll see a few regulars appearing in both years, as well as, some newcomers to the list. However, keep in mind, because of COVID-19 and the greatly abbreviated volunteer program, this year’s reporting numbers are, as expected, quite lower. What’s interesting is that the many years of work by the Kauai Hawaiian Monk Seal Conservation Hui has educated the public so well that the hotline is still ringing. Concerned citizens are calling and reporting seals. This is in great part due to the diligent outreach efforts of the volunteer team.

So, here goes:

  1. With 90 reported sightings, one-year-old female RL58 tops the list. She was born to the famous RH58, also known as Rocky, in July of 2019. She remains close to her natal beach and has a preference for hauling out in rocky areas rather than sand, and doesn’t socialize with other seals much.
  2. With 66 reported sightings, the 20 plus year-old-female RK13 ranks second. She is the most well-known seal on Kauai’s east side, easily identifiable by her blind white left eye, many body scars, and worn red flipper tags that read 5AA and 5AB. She has given birth at least three times that we know of, including in 2012, 2015, 2018. Hopefully she will continue that pattern and pup again in 2021.
  3. With 61 reported sightings, seven-year-old RN30 ranks third. He tends to range far and wide with reported sightings of him from many different beaches on Kauai and Oahu.
  4. With 52 reported sightings, the seven-year-old R353 ranks fourth. She first showed up on Kauai in 2016 and is likely a Niihau girl. The past couple of years we watched her gradually get very large and pregnant, disappear for a couple of months and then return after losing about half her body weight. We suspect her pups were born on Niihau.
  5. With 45 reported sightings, one-year-old male RL08 ranks fifth. He was infamously fat as a pup, nursing two full weeks longer than the average nursing period of 40 days. It appears that 54 days of fatty milk gave him a head start as he now looks more like a 3-year-old seal, rather than the yearling he is.
  6. With 44 reported sightings, R3CD and RN44 are tied for sixth. These 6 and 7-year-old males, respectively, are difficult to tell apart. They are the same size, have very few scars, and often challenge each other for the right to rest near certain females. However, RN44 has recently become a regular seal sighted on Oahu, so R3CD may have less competition in 2021.
  7. With 43 reported sightings, two-year-old female RKA2 comes in at a very close seventh. She’s the offspring of the late, great, RK30, and has become a very faithful east side seal, although originally from Milolii Beach on the Na Pali Coast.
  8. And finally tied for eighth, with 41 reported sightings, are the four-year-old R1NS and nine-year-old RK90. These healthy large females are both most likely from Niihau, but tagged on Kauai as yearlings. R1NS is currently looking rather large, and we suspect she is pregnant for her first time. The question is, where will she go to pup?

Let’s continue last week’s post about male hierarchical displays and posturing among Hawaiian monk seals. Because they’re at it again. But this time, they’re vying for the attention of a female. Not just any female. A pregnant one. A very pregnant one.

Last Thursday, when a very pregnant RH58 (yes, that RH58, also known as Rocky the Celebrity Seal) showed up after making the oceanic crossing from Oahu, another seal, seven-year-old RN30 appeared, too. (RN30 was born to in 2013 to first-time mom RO28, who died of toxoplasmosis earlier this year.) RN30 approached RH58, getting close enough for her to display in a manner that indicated she wanted him to back off. That is, she lifted her head, opened her mouth, and vocalized at him.

By the next morning, another male had arrived. This one, R3CD. He was estimated to be six when he was tagged in 2017. RN30 positioned himself between the RH58 and R3CD. The dynamics got really interesting when RH58 hauled her heavy body into the water for a gravity-free swim. The boys followed, of course, and RN30 worked hard to keep his position in between the two. While RH58 floated about languidly in the shallows, RN30 darted over to R3CD. They’d splash a bit. Then, he’d zip back to check on RH58. Rinse. Repeat.

But the antics were just getting started. Things got more interesting when another pregnant female showed up–RK28. Her appearance kept the boys busy while at the other end of the beach, RH58 quietly gave birth to PK2.

By day’s end on Friday, RN30 was still annoying RK28 while R3CD quietly watched over PK2 and RH58.

Sunday morning broke to reveal RK28 had given birth to PK3.

Now, the boys are still hanging around but not quite as attentive. Typically, once a pup arrives, the males’ interest wanes, leaving moms to snuggle (bond) and feed (nurse) their young.

And with that bit of background, meet PK2.

And PK3.

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.

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!
