Fledging Albatross, Baby Seals, and Immersion Suits

"I'm flying!!!"  Well, almost.  The kaʻupu chicks have started to fledge this week -- We've seen several taking off from Tern and Trig Islands.  They'll continue fledging over the next month.  The mōlī (Laysan albatross) will start fledging in the next couple weeks as well.  These birds will spend the next several years at sea, not returning to land until they are ready to start learning how to be parents.  Most of these birds will return directly to Tern.  Its been very exciting watching them grow up!  Photo by Paula L. Hartzell.

Team Tern on East:  From left to right, Dan Rapp, Sarah Youngren, Kristina Dickson and James Macaulay banding black-footed albatross (ka'ula) chicks on East Island.  We are excited about banding on the outer islands of the atoll, because this information will help us better understand how these birds adapt to changes in island geomorphology, storm events and tsunamis.



An ʻilio o ke kai mom and pup move up on land to sleep for the night.  A healthy mom will stay with her pup throughout the nursing season, never leaving the pup to feed.  A fat mom is a good mom, because she births fatter pups and nurses them longer.  Attentive moms are also more successful at protecting their pups from sharks.  Photo, with La Perouse Pinnacle in the background, by NMFS crew Mark Sullivan.
View of Gin Island from Little Gin Island.  The NMFS crew has been camping on Gin for two weeks straight, in an attempt to monitor and protect pups on that island. Can you imagine staying on such a small low island overnight by yourself?!?  Photo by Paula Hartzell.
Lindsey Kramer and James Macaulay cheerfully pump gas into -- and back out of -- the Spam.  Sometimes you think you're going somewhere, sometimes not.... But they kept a smile on their faces regardless.  You never know what the conditions or challenges will be, so you have to be willing to roll with the punches...
Safety Training!!! The team practices with immersion suits... Kinda funny on a tropical island!!!  We need to know how to use the suits, though, if we have to evacuate via boat for long periods of time, or at night, when hypothermia is a real possibility.  Still, it was pretty funny to see the honu swimming up to check out the bright orange people....  Here the team practices making a raft with their bodies, for an ʻinjuredʻ person to rest on top, out of the water.  Practice makes perfect -- especially when you need to be able to rescue yourself, even when the situation is scary.  It is very important to be knowledgeable and practiced at emergency procedure when youʻre this far out at sea.

Sarah demonstrates relaxing in an immersion suit...a tricky proposition at best.  :-)  
Beauty and the Beast:  Fratricide in the MABO world.  Masked boobies, ʻA makaʻele, have two eggs as insurance in case they lose one.  If both eggs hatch, either the parent or the other chick will most often kick the weak one out of the nest to die (and hence why twins are rare).  Mark Sullivan caught this event on camera -- Nature is often incredibly beautify, and horribly harsh at the same time.

Aloha kakahiaka!

This has been a great seal week -- Some of the seals had a romantic Valentines Day (really!), and we are seeing lots of nice, fat females.  Nice fat females means nice fat babies, and enough fat for the moms to feed them throughout weaning. (The moms don't eat from the time they give birth, until after they wean, so lots of body fat is essential.)  Go fat seals!
This nice fat momma seal is 18 years old, and has had 7 pups so far.  Go Momma!
   It has been rain, rain, rain for quite a while now -- so we race out for a quick snorkel whenever possible.
Little toby guards his junk.

We also had some water-based training with the Miller board.  This type of safety practice is very useful in figuring out what we can and cannot do - and so we all feel more comfortable handling this equipment when we actually need to evacuate a hurt or unconscious person in the water.

Oops!  Kinda got that one backwards.... Now her head is down...  Important lesson that we won't forget next time!


A successful rescue!!  Kristina (in wetsuit) demonstrates the proper way to lift, while the others demonstrate improper lifting technique.  Way to go, Team!  :-)

And last but not least... the Photo of the Week:
