New:

• Subadult female R7AA was sighted with a medium sized circle hook in her left cheek. The Kauai team responded and were able to capture her on the beach and remove the hook without complications. A 2-foot heavy gauge monofilament leader and pigtail swivel was attached to the hook which presented a serious entanglement and drowning hazard. The seal was immediately released and has been sighted since with no signs of infection.
• An untagged adult female that has not been sighted on Kauai previously hauled out at Poipu and has since become a somewhat regular seal on the south shore. This seal was previously sighted on Niihau in 2017 with a pup and has an ID of R371. She has numerous scars and can be easily identified, even without flipper tags.
• Another untagged Niihau adult female was sighted for the first time on Kauai’s north shore. Her ID is R367.
• Another untagged likely Niihau seal molted at a remote east side beach. He is a new seal to Kauai and has a temp ID of Temp361.
• Yearling RL58 observed with a large fresh cookie cutter shark bite very close to the genital slit. The seal was closely monitored for possible infection, and the seal has quickly recovered.
• A volunteer observed a tourist attempt to pet the large adult female RK90 at a west side beach. The seal responded by leaving the beach. Outreach was conducted by the volunteer.

Updates:

• RH38, the seal rehabbed at KKO and released in July, continues to thrive on north shore. Her tracking tag remains attached, however the battery has died so no further data is being transmitted.
• All of the 6 pups born this year have been sighted recently and continue to thrive.
• Displacements: No displacements this month.
• Molting: Adult male RN02 spent 3 weeks at the busy Poipu Beach in pre-molt, molt, and post-molt which required extensive volunteer coverage. One other seal molted this month in less busy areas.
• Vaccinations: A booster morbillivirus vaccine was given to new juvenile seal R1NI.
• Bleach marking: none this month.

Research/Support of PIFSC
