Four Months on Tern Island
This has been quite an odyssey! I've been thinking for several days how I could sum up these last 4 months and here is that effort. I worked very hard to get myself and the house and my responsibilities at home in order before I came, but a lot happened while I was gone that was beyond my control. Who can prepare for the death of your Mom while you're away. Another death in the extended family who had been a friend and mentor for 40 years added to that sense of loss. Then to cap it all off our home was burglarized in broad daylight and Jan had to deal with those feelings of fear and violation without me there. I wonder if any other 4 month period in my life had quite this many such events come together at one time. Then to have it all happen while I was living off the edge of the planet was difficult some days. I am lucky to be part of a family that dealt with it all and told me to stay where I was and complete my duties.
It is hard to think of Tern Island without the previous events being first in my mind but my time here has been the experience of a lifetime. So many events come to mind that it is hard to single out ones that were special, but here are a few that stand out. Living on a small island in the mid North Pacific Ocean. Sharing that Island with a handful of people and 200,000 seabirds. Traveling by small boat across the atoll with no land in view except La Perouse Pinnacle. Swimming and snorkeling at La Perouse felt like you were swimming in mid Pacific with nothing but the horizon in view. Watching many sunsets that showed the green flash as the sun dipped below the horizon. Dozens and dozens of colorful new fish to be observed. Common jobs, like at home, such as raking, shoveling, sweeping, or washing but with dozens of curious albatross chicks looking on. Banding 100 plus albatross chicks in a day. Catching and holding more than a hundred albatross chicks the next day while your partner banded. Seeing a Bristle-thighed Curlew. Watching turtle hatchlings emerge from the sand. Eating my breakfast every morning sitting on a bucket on the front porch in the midst of thousands of seabirds. Having Sooty Terns perch on my head almost every day I worked in the colonies. Monitoring, and banding, 6 different species of seabirds. Watching highly endangered Hawaiian Monk Seals out my bedroom window. Never being away from the sound of the surf or the sounds of 200,000 seabirds.
The whole experience will take months to process in my own mind. There will be lots of organizing of pictures and talking to Jan and other family members to help put it all in perspective. It has been the experience of a lifetime and one of which dreams are made.

Thursday on Tern Island
Today was a mixed bag of work. I began the day banding Masked Booby chicks. The chicks are larger than a Mallard duck and are nearly ready to fledge. They are fish eaters and have sharp serrated beaks so some care is required catching and restraining them for banding. While we were banding the MABO chicks a Red-footed Booby landed on my head and sat there for several minutes. I have Sooty Terns roost on my head every day that I work in the colonies but this is the first time a Red-footed Booby has ever roosted on my head. The simple pleasures continue here on Tern. One of the turtle techs has left for home and the other one, Tammy, is banding hatchling turtles. The hatchlings are smaller in diameter than a tennis ball and only about ¾ of an inch thick. The bands are tiny and clip on the right front flipper. It was interesting to watch the process. We will see many more as the program hopes for 400 banded hatchlings. The rest of the day was spent working on maintenance projects and doing 3 loads of house laundry. Just like home.

Life on Tern Island
Our Internet use has been so restricted it is hard to keep up this blog. I will continue with small posts but I still can't use pictures. The biology is slowing down with most of the nesting activity finished. I still see new nests occasionally in my Red-footed Booby and Red-tailed Tropicbird plots but they are rare. I still monitor these plots every other day but the numbers of birds are way down. The biggest job left for me is banding about 130 Red-footed Booby chicks that will fledge within the next 3 weeks. We continue to have rainy days every few days so our water storage looks good. I have enjoyed my time here immensely but I can see the end coming.

Turtle Barriers
Green Sea Turtles are strong persistent animals and can get themselves into dangerous situations around the buildings and runway on Tern Island. They crawl up on the beaches, usually during the nighttime hours, to dig their nests and lay eggs. If they leave their nest and crawl into a situation where they are trapped and exposed to the daytime heat they will die. To prevent this, turtle barriers have been built over the years to stop the turtles from getting themselves into dangerous situations. The barriers have been built where turtles are known to escape the beaches and get entrapped. They take many forms and the pictures in this post show most of the types. The turtles move lots of sand so we need to shovel the sand away from the barriers regularly or the turtles will crawl up the ramps of sand they have piled up and crawl over the barriers. ---Notice the height of the sand piles beyond the albatross chick and the wood barrier.---

The Boat Hoist
This sequence shows taking a boat out of the water. This process happens almost every day and usually several times per day. The boat is lifted straight up and then is swung around onto the concrete apron and lowered onto its trailer so it can be rolled out of the way for other boats to be launched or retrieved.
The Biologist and the Birder
After spending 3 months on Tern Island working as a Field Biology Technician, I'm beginning to see differences between a biologist and a birder. I've spent 30 years as a birder and most of what I've done as a birder in those 30 years, involved observing and thinking about individual birds. The albinos in the previous post are a good example. That kind of variation is fascinating to me. Steve, the biologist that I'm working for, had a passing interest when we showed him the 2 albino chicks but he didn't even take pictures. His interest, as a field biologist, is the population. One pure white, pink eyed, Brown Noddy chick, that probably won't survive, has very little biological meaning. It is a genetic mistake that occurs rarely, but consistently, and is interesting only for it's rarity. It has very little meaning to the total population of Brown Noddys.

Albino and Partial Albino
In the past 2 days we have discovered 2 color variant birds. One is a Sooty Tern chick which is a partial albino that is mostly white but has some color in the eyes and bare skin parts and a dark wash on it's feathers. The bottom picture, which shows the partial albino Sooty Tern chick has a normal colored chick in the bottom right to give a good color comparison. The black and white bird in the upper left in the same photo, is an adult Sooty Tern. The true albino is a Brown Noddy chick and the picture shows it with the adult Brown Noddy.

Birthdays
I have been blessed with many interesting and memorable birthdays. There have been at least 5 birthdays on backpacking trips. The first back country birthday I remember was near Bench Lake in Kings Canyon N.P. about 1966. Jack brought in lots of goodies for us to eat. There were at least 2 up the Deer Cove Trail in Kings Canyon with Jan, Hannah, Jens, and again Jack. There were 2 in Big Whitney Meadow just south of Mount Whitney. There was one in Voss, Norway with a newly met cousin on my Moms side of the family. There was even one in Buffalo. Now here is another memorable birthday on Tern Island in the mid Pacific. Monica baked this cake for our 4th of July barbecue and before the cake was cut one candle was placed and lit, and they all sang for me.

A Good Story of Marine Debris
Reef Debris
One of the jobs that we occasionally get involved with is collecting derelict fishing gear from the reefs. The seal researchers spend more time in the boats so they perform this task more often than the FWS volunteers. When I went out with the Monk Seal researchers we found this wad of line and other fishing gear, cut it loose from the reef and loaded it onto our boat. This kind of gear goes right on trapping fish, birds, and reef organisms long after it is lost so it is good to remove it whenever it's found. Derek is on the left and I'm on the right. The picture was taken by Mark Sullivan
East Island Turtle Camp
Last Wednesday we changed the turtle techs again and I was finally in a spot where I could watch and take pictures instead of working. We put out a stern anchor, drift in close to the beach, and one person holds the bow line while the rest wade back and forth carrying water and supplies. Most days there are fewer people involved but this was an outing that involved everyone on Tern going to see the Tiger Sharks that congregate when the albatross fledge. One picture shows the camp from offshore a ways and the rest show the movement of gear back and forth to the beach. The pole is left from the Coast Guard days and has a web cam that is monitored over the internet.

18 Year old Albatross
One of my tasks recently has been to find dead albatross chicks and remove the bands that we just installed. The paper trail behind the newly installed bands will be more useful if the dead bands are shown. On Saturday I took a band off a dead adult Black-footed Albatross (BFAL) that I found during this task. This afternoon I was completing the paperwork and discovered that the dead BFAL I found had been banded here at Tern Island on June 5, 1990. The bird was 18 years old and a couple of months. That is far from a record age but it is still pretty amazing! These birds travel many thousands of miles searching for food each time they raise a chick, so that band may have traveled 300,000 or 400,000 miles across the north Pacific on the leg of an albatross! These are not exaggerated numbers. It could have traveled considerably farther. (The picture is not the same bird I found dead. It shows an adult BFAL and its chick just to illustrate the kind of bird I'm talking about.)
Alpha Codes
Black-footed Albatross-BFAL Red-tailed Tropicbird-RTTR Sooty Tern-SOTE White Tern-WHTE You do begin to see patterns in how they are produced but some of the uncommon ones I still have to look up. The common ones, that I have memorized well, help to shorten the time that I spend on some of my data entry paperwork.
