Field Report: June

Updates for our Kauai seals and pups.

RK30 weaned her pup, PK1. This pup most likely nursed 49 to 50 days, making this a very big pup. On Monday, June 27th, she was tagged and vaccinated and is now, officially, RH38, (tags H38/ H39).

RO28 arrived from Oahu and pupped, PK3 on June 15. Both are doing well.

Vaccinating seals on Kauai.

The Kauai coordinators are in the process of vaccinating Kauai seals against Morbillivirus, a disease that causes measles in humans and distemper in dogs. To protect our rare Hawaiian monk seals, the first ever vaccination of wild seals has been initiated, as epidemics of this deadly virus have devastated other seal species populations around the world. So far, 13 Kauai seals have received their initial vaccination and some their second booster shot. We are now earnestly looking to booster several male seals, and volunteers can assist us by looking out for RF28 ( red tags, and transmitter on his back, on the north and east sides of Kauai), and N1AA (black tags on the south and west sides of the island). Also, RN30, R8HY subadult males found primarily on the east side often Ahukini cove.
Here is a video of how seals are vaccinated. We will put out a list as time goes on, to identify which seals we are looking for to booster in the 3-5 week window and would truly appreciate assistance in looking for them.

RF28 and RF30 released and doing well.

On May 27, RF28, a juvenile male seal, was found with an ingested hook that was successfully removed on Oahu by a veterinary team. He was soon released back on Kauai with a transmitter on June 2.

A week later, we were surprised to find another internally hooked seal, RF30, a juvenile female! She was located at the Poipu county beach park keiki pool where she was logging and acting strangely. A team was assembled for a water capture using fence panels and crowding boards. This challenging capture was successful due to our many fine volunteers that rallied on a very short notice. Without volunteers to find and assist with capturing these injured seals, none of these successes would be possible! We supremely need and appreciate all our volunteers! RF30 was also transported to Oahu by a US Coast Guard C-130. She was found to have some swelling in the throat where the hook was lodged and at the base of the tongue. It was successfully removed using an endoscope and specially designed tools. Four days later RF30 was flown back to Kauai and released on the east side of the island where she normally resides. Both seals are fitted with satellite tags that are solar powered.

Other marine species:
News from NOAA Fisheries Sea turtle program. If you see a honu or ‘ea on the beach or in the water, please remember:

  • View sea turtles from a distance of 10 feet (3 meters). In Hawai‘i, we view turtles respect- fully. Give turtles space and don’t feed, chase, or touch them.
    Hawaiian honu bask on the beach. This is normal behavior. Don’t try to
    push them back into the water.
  • “It’s OK to help!” Fishermen, check your gear often, use barbless circle hooks and adhere to state gillnet rules. If safe for both you and the turtle, release accidentally caught turtles by fol- lowing these steps:
  1. REEL-IN the turtle carefully
  2. HOLD by its shell or flippers
  3. CUT LINE as close to the hook as possible, and
  4. RELEASE with no (or as little) gear or line attached.
  • “No white light at night.” Use wildlife friendly lighting near the coast (yellow/amber and shielded lights). Don’t use flash photography, and keep lights and beach fires to a minimum from May to December, when turtles are nesting hatchlings are emerging.
  • Avoid beach driving. Off-road vehicles crush nests, create tire ruts that trap hatchlings, and degrade habitats. Driving on the beach is also illegal in most areas.
    Prevent debris and rubbish from entering the ocean. Participate in beach and reef cleanup activities.
  • Report all hawksbill sea turtle sightings, any nesting activity (turtle tracks or nest digging), and injured or dead turtles to NOAA’s Sea Turtle Stranding Hotline on Kaua‘i: (808) 274-3344.
  • Report illegal or suspicious activity that may result in turtle injury or death by calling the Division of Conservation and Resources Enforcement (DOCARE) at
    (808) 587-0077 or 643-DLNR.

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.

Field Report: Summer 2014

Banner pupping year on Kauai – 5 pups!

In addition to the previous pups reported (PK1, PK2 and PK3) two more pups were born on the north shore of Kauai. RH58, a well known and very successful mother gave birth to PK4 on June 28th. RK28, another proven mother gave birth to PK5 on July 16th.

Pups only spend around 40 days with their mothers, during which they gain massive amounts of weight from nursing. The typical pup is born at 35 pounds and gains between 100-150 pounds in a short 5-6 weeks! The mothers fast during this time and convert blubber into very rich milk (twice the calories of heavy whipping cream).

When the mother’s blubber is depleted they abruptly wean their pups by departing, usually at night, and do not return. The young pups are large, healthy and strong swimmers by this point and quickly learn to forage on their own. They are still very naïve, however, and can easily be taught to seek humans for food and company, so it’s crucial that we monitor these ‘weaners’ and make sure humans do not interfere with this critical developmental stage. Shortly after weaning, the pups are flipper tagged and given new permanent IDs, all of the pups born in 2014 were tagged as the ‘F’ cohort (i.e. RF22, the R identifies Main Hawaiian Island seals)

Meet the 2014 Kauai ‘F’ cohort:

Off-Leash Dogs: Tragically, PK5 was killed by stray dogs when he was only two weeks old. The incident occurred during the night and was therefore not witnessed by our diligent pup-sitters. Tracks, blood, and injuries to four other seals, including PK5’s mom, indicated that the mother seals did their best to protect their pups. PK4 (now tagged RF58) had over 60 bite marks on her body and developed major abscesses around her neck. She immediately received medical attention and disease screening by a NOAA veterinary team, and fortunately healed quickly. Currently she is doing well and learning how to be an independent juvenile seal. Permanent neck scars will help us identify her, but pose no risk to her survival.

This was the first known monk seal death caused by a dog and a warning to all of us that we must keep our dogs on leashes (it is State law on all beaches) and strongly encourage everyone else to do the same.
