BARROW, ALASKA — Well, it is midnight and even though I promised myself to go to bed earlier, I am not able to withstand the draw of the midnight sun. One more walk down to the pack ice to look for another group of Common Eiders, one more discussion about changing ocean salinity, one more...

Special delivery for the birds
During the salad days of the Cooper Island Black Guillemot colony, in the late 1980s, there were 200 wooden nest sites, which I had created in the late 1970s with wood left on the island by the Navy two decades earlier. All 200 nests were occupied by breeding pairs and the colony enjoyed high breeding...

Solitary scientist at the top of the world
COOPER ISLAND, ALASKA — The subtitle of Darcy Frey’s 2002 NY Times Magazine article on the early impacts of climate change seen on Cooper Island, referred to me as a “lonely scientist at the end of the earth”. This wording was likely the work of an editor, who wanted to portray the “forlorn” qualities inherent in the word...

Holiday greetings
COOPER ISLAND, ALASKA — Celebrating a solitary Independence Day on Cooper Island with a few hundred black guillemots. While many guillemots are still laying eggs, yesterday I saw the first successful fledge of the year — a barely flying snow bunting that was still being fed by a parent. Snow bunting nests can produce up to seven chicks and feeding...

George and the guillemots get used to their new homes
COOPER ISLAND, ALASKA — While the start of every field season is always an exciting (and frequently stressful) time, this year the start of the Cooper Island field season had more excitement than most. Preparations began earlier than normal as March and April involved acquiring, modifying and transporting 150 Nanuk plastic cases to replace the...
