Big Eggs


Testing the strength of my relationship and putting my friends and family on hold for six months, I came to this isolated runway far from home to see one thing…albatross. The boobies, frigatebirds, and even shearwaters are interesting to say the least, but the albatross demand respect and admiration. Three thousand strong and increasing in attendance each day, two of the three North Pacific species now dominate the landscape. Their presence on the island provides validation for my decision to invest half a year of my life to Tern. Long seven foot wingspans seize the wind like the sheets of a schooner, harnessing this resource for flight with only the slightest investment of energy. Walking down the runway I can hear the buzz of primary feathers vibrating past my ears as a Laysan tacks in a figure eight (known as dynamic soaring), dipping so low only centimeters remain between the hard packed ground and its wingtips. Just as a plane lowers its flaps to spill air from the wings, the bird pivots its broad wings vertical to the ground, stopping all forward motion and dropping it from the sky; possibly the first time this bird has touched land in over a year. Research suggests that albatross remain loyal both to their partners and their natal islands. Most pairs will return to the same patch of ground every other year to build a rudimentary nest suitable for an egg. Black-footed Albatross (BFAL) are the first to lay, followed by the Laysans a few weeks later. As of yesterday, I counted eleven BFAL eggs in four rectangular plots throughout the island; part of a weekly check to sample the breeding success of these birds from egg laying to chick fledging. These eggs will take nearly two months of incubation effort from the parents before chicks begin to hatch just around the time of my birthday in mid January. Now the waiting game begins.

  2. Second that, however I so admire your drive and passion in marine science work.
