Monk Seal Monday #30: Another (P)update »

Field Report: July Update

August 13, 2018 by Kim Steutermann Rogers

Monthly Update:
The Kauai team logged 35 individually identified seals on Kauai in July for a grand total of 414 seal sightings this month. This equates to over 13 monk seals sighted and reported per day.

June: 315
May: 332
April: 302
March: 299

New:

  • RH58 “Rocky” gave birth to male pup PK5 on 7/16/18.
  • A pup switch occurred for the first time on 7/20/18. RH58’s pup PK5 was forcefully taken by another mother RO28 who left her female pup PK4 alone on the beach. The Kauai team successfully reunited the correct moms with pups later that day. Another pup switch occurred on 8/2/18 when RH58’s pup PK5 was seen with another mother RK28 who had left her male pup PK3. Again, RH58 was alone but searching and calling for her pup. The Kauai team attempted to reunite the correct mothers to pups on 8/3/18. RK28 quickly took her pup PK3 back, however, RH58 rejected her pup and became aggressive toward him. The pup was left on the beach overnight in hopes that RH58 would reunite naturally. On 8/4/18, RH58’s pup PK5 was again found with RO28 at sunrise. RO28’s pup PK4 was nearby and began calling for her mother, who quickly left PK5 and rejoined PK4 without human interference. A final attempt at re-uniting PK5 with his mother RH58 occurred that morning of 8/4/18, however she continued to be aggressive toward the pup. The Kauai team captured PK5 (now permanent ID of RK58) and transported him to Lihue for USCG C130 transport to Ke Kai Ola for rehab mid-day on 8/4/18.
  • The first pup of the year, now weanling RK42, was de-hooked by the Kauai team on 7/28/18. A large j-hook with 5’ of 100 lb test monofilament leader with swivel attached was removed from the right side of the seal’s mouth.

Updates on previous reports:

  • RK28 gave birth to PK3 on June 26.
  • RO28 gave birth to PK4 on June 30.
  • Bleach markings: No bleaches were applied.
  • Morbillivirus vaccinations: No seals were vaccinated.

Research/Support of PIFSC

  • Sub-sampled placenta from RH58.
  • Sub-sampled scat, molt, and tissue plug samples accordingly.
  • Logged all seal sightings for Pacific Islands Fisheries Science Center (PIFSC) database. Organized photos and reported sightings, molt tallies, survival factors to send to PIFSC.

    […] In 2018, these same two moms also pupped on the same beach. Only this time, they were involved in an unusual series of “pup switches” that resulted in one pup being rejected and rehabilitated at Ke Kai Ola, the monk seal hospital on Hawaii Island. (For more information on that event, click here and here.) […]
