Paula's very last blog post....

Aloha kakou!

I have had so much fun, and learned so much at Tern Island Field Station over the past three years.  I send sincere thanks to all the people who have worked to improve the station, the quality and effectiveness of our work there during this time -- as well as the hundreds of others who have done so in the past.  A particular special thanks to all the volunteers who have donated their time because of their passion for conservation and protecting our wildlife and refuges.

Mahalo nui loa!!!

As a parting message, I attach links to a couple of classic videos during my stay at Tern....

and finally, a salute to TeamWork:

The Original Team Tern: a Well Oiled Machine

Above and beyond all of our hard work and efforts, thank you to all of the wildlife -- birds, seals, turtles, people, fish, invertebrates, and habitats marine and terrestrial.  Without you, our life would have no joy.

New Crew on Tern

Welcome to our new crew on Tern!  The Kahana arrived on Monday with the new summer crew:  Summer Manager Meg Duhr Schultz, and volunteers Catherine Fox, Ryan Potter, and Megan Juran.  The new and old crew will work together over the next 10 days, passing the torch.  The winter crew will be leaving when the Kahana comes through on its return trip to Honolulu, and Meg will be taking over the blog.

Abram Fleishmman and Megan Juran stack milk in the food room.  All food must be labeled with date of arrival and stored in its proper place.  This food will last the crew -- plus folks from NOAA's seal and turtle crews this summer -- until October, when the next crew switch-out occurs.

Biologically, the honu (Hawaiian green sea turtles) are starting to show up in slightly higher numbers -- from 0-1 per day on Tern in mid-winter, to more than a dozen per day now.  (It will be more like 100/day on Tern later, and double that on East Island in peak season.)  We're seeing a few turtle 'rafts' or 'dog piles' -- a bunch of males vying for a female turtle's attention. 

Basking honu on Tern Island

'Old style' metal tag, #G692.  We were lucky to happen to see the first female turtle of the season digging high up on the beach, checking out good spots to nest later in the season.  She was last seen nesting in 1996 and 2002. 

 We also saw two red-footed boobies (ʻĀ wāwae) with signficant oiling in the past month.  One had about 15% of its body covered, and another had about 30%.  We've spotted a handful more with small (quarter-sized) spots.  The oil looked to be old, but we collected feather samples, just in case the oil needs to be analyzed. We'll be keeping a sharp eye out for additional oiling, and are starting to photograph the 'small spot' birds in order to assess how many birds have actually been affected.

Sarah Youngren finds a returned invasive -- sandbur -- under the clothesline.  It was probably accidentally reintroduced by people coming back from East Island, where the weed reappeared four years after 'eradication' -- perhaps due to old seed bank being exposed by record-breaking turtle nesting activity last summer.  Bird, seal and turtle crews will have to be particularly careful not to accidentally move these sticky seeds around more; right now we're hoping to keep re-eradicate the weed in the next several years.

The only bummer news for this week is that because Paula (the manager) has to go back to Honolulu to work in the office, and won't be staying or returning this summer, the benthic monitoring project we were planning to start this winter (but hadn't yet because we had no working boats) will not be carried out.  Of course Paula is very sad to miss out on all the summer actvities (particularly the benthic plate project, as well as helping out the turtle and seal crews), but Meg will be carrying the torch high and proud, and all the other activities will carry on under her guidance.

Dakshina Marlier (USFWS), Abram Fleishman (USFWS), and Morgan Gilmour (UCSC and USFWS) will also be sadly returning to Honolulu, but they have great plans after that!  Dakshina will be moving on to a summer biking position in Alaska, and Abram and Morgan have wildlife jobs in California.  Morgan may be entering graduate school, and if she gets the permits, returning to Tern next winter to continue tagging albatross and boobies, and working on her dissertation tagging great frigatebirds!

More good news is that Sarah and Dan will be staying on at Tern to work on Paula's data quality project, funded by the USFWS Inventory and Monitoring Project, so we can get some of the 30 years of bird monitoring data.  They'll also be able to complete their work on acoustics, plastics, burrowing seabird habitat, working alongside Meg, Megan, Catherine and Ryan.  Yeah!!!

Goliath, is also the heaviest of our chicks, and part of Dan Rapp's study looking at the effects of plastics on chick growth.  Photo by Sarah Youngren.

New Years on Tern Island

Hauʻoli Makahiki Hou!!!

An 'iwa (great frigatebird) welcomes you to Tern Island.

Theme for 2012?  Sesame Street has nothing on us -- There are plenty of birds to count here!

We have lots and lots of albatross breeding now: about 3,000 ka'upu (black-footed albatross) nests and about 1,000 mōlī nests (Laysan albatross).  Team Tern Awesome has been crazy busy counting these birds -- or more specifically, reading the auxillary bird bands ('aux bands') on albatross this past month. Every year in late December and early January, we read every aux band on about 10,000 albatross across the island. Then we do it again. Then again. Then yet again. We're in the midst of the 3rd sweep right now, and have already counted over  25,000 aux bands, and still have one more sweep to go!

An overachieving ka'upu.  This ambitious parent is brooding one egg, with two more in the nest.  Where did he/she get those, do you wonder? :-)  Photo by Paula L. Hartzell.

The point of all this counting is to determine what the breeding population of mōlī (Laysan albatross) and ka'ulu (black-footed albatross) is on Tern Island, as part of a mark-recapture study.  The number of breeding albatross here is very important for two reasons:  (1) because while Midway and Laysan Islands have much, much larger albatross populations than Tern, we are the ones who conduct most of the detailed biological monitoring.  (2) Tern is also a more protected environment than Midway or Laysan, so may serve as an important refugia for seabird species nesting here -- Just like when the tsunami wiped out large portions of Midway's and Laysan's breeding grounds last year, but did not affect Tern Island.  We also have the most dense population of nesting albatross in the Hawaiian Islands.  (I don't know how the Japanese populations compare.)

The 'a maka'ele (masked boobies) are staking out territories now, and getting their nests set up.  Right now we only have two nests on island, both with the customary 2 eggs.  'A maka'ele lay two eggs as 'insurance' when they lose one -- twins are rarely ever raised all the way to fledging.  In this picture, the female is on the bottom left, and the male on the top left -- You can tell by his brighter beak.  (That only works sometimes, though.)  These are one of the few seabird species you can identify the sex of individuals:  The males hiss and the females honk.  The females also defend their offspring more viciously. 

In December, we also participated in Audubon's annual Christmas bird count.  Right now there are about 13,000 birds on Tern -- Relatively few compared to a summer population of about 1/4 million birds, due largely to high numbers of sooty terns in the summer.  But that's still a whole lot of birds on an island about 930m x 120m.

We don't just count the birds, of course, although that's a really important part of our work here.  Morgan Gilmour is satellite and GPS tagging ka'upu, mōlī, and 'a maka 'ele to see where they forage during nesting time.  That will help us understand not only where they go to get their food, but how that is impacted by fishing, marine debris, climate, and other factors -- so we know whether we need to do more to help, or whether they're just doing fine on their own (which is best of course!). 

Dan Rapp is working on quantifying the amount of plastic that seabirds ingest, paying special attention to mōlī and Tristram's storm petrel chicks, since his previous work suggests that these are the hardest hit by plastics.  Sarah Youngren has set up acoustics monitoring equipment to see if we can use this method to reduce our impacts to the birds while monitoring, or even use this monitoring system for areas where humans can't stay!  We're also doing some very initial testing of night vision (trail) cameras for burrow monitoring.  Abram Fleishman is creating a new map of Tern Island, with natural, man-made, and science-important features -- which we really need badly because our maps are really out of date.  Dakshina Marlier is working on developing some training materials for future volunteers on Tern Island, to help them appreciate the value and story of Hawaiian culture and history here.  We're all working with several Hawaii classrooms, along with Barbara Mayer and NOAA's Wes Beyers, on special projects.  Paula Hartzell is summarizing our work, and providing some statistical analyses of 30 years of monitoring for this year's annual report -- It's really important that we publish what we're doing, so people can actually use this information! 

We're also working long hours trying to get our boats -- our newest engine is 9 years old -- running so we can do outer island surveys.  We finally replaced the fuel pump, cleaned the starter and carburetors, replaced the manifold (which had to be sawed off, the bolts were so rusted), prop, bearings, and all fluids and filters on our whaler, the Mōlī -- and now the lower unit is toast.  Mutiply that times a total of 5 outboards, the others of which are worse.... Aarg.....USFWS doesn't have funds to get us new engines, but you can only repair an engine with limited time and funds so many times.  If anyone wanted to give us some tiller-driven 50hp Honda engines so we could actually get to the outer islands, we wouldn't complain!

Manu o Kū (white terns) are nesting as well -- but they nest year-round, so that's not unusual.  Among the myriad of projects he's taken on, Dan Rapp is going to be tracking how many times individuals birds relay during the year.  Photo by Abram Fleishman.
