Graduate student Drew Sauve recently returned from Cooper Island. He describes his collaboration with George in this guest post. The Black Guillemots on Cooper Island are one of many wild populations that are responding to climate change by changing when they lay their eggs. These Arctic seabirds want to lay their eggs as soon as...

Hatched! So far, so good for the 2018 chicks on Cooper Island
August 11, 2018: Field report Hatching is finally over with one very late egg hatching today after having been incubated for 34 days; 28 days is normal. The oldest nestling is 16 days old; the chick is gaining weight and doing well like all of the other 45 nestlings. While the main pack ice is...

First chicks of the 2018 season
August is the rainy month of our field season, and the first day of the month was tough for us. During our morning nest checks, it wasn’t easy to keep our hands warm in a steady soaking rain, coupled with a windchill of 27 degrees Fahrenheit. The fingerless gloves I wear daily in the summer...

2018 Census
In this week’s field report, George talks about specific birds as well as the overall report of his 2018 Black Guillemot census on Cooper Island. Nature, when observed or monitored for any extended period, typically provides a predictability that is reassuring in its consistency and sufficient surprises to keep one engaged. For over four decades,...

Arctic Worries: Climate change impacts communities and wildlife in the Arctic
Science writer Jenny Woodman of Proteus writes about Cooper Island research and the current field season. George Divoky frets–with good reason. In 2016, CNN Correspondent John D. Sutter called him the man who is watching the world melt. The description is as distressing as it is apt. George sends us regular dispatches from a small field camp...

Seabirds and Sea Ice
Over most of its range the Black Guillemot is a nearshore seabird, occupying coastal waters during both the breeding and nonbreeding seasons, as do other members of the genus Cepphus. Pelagic or open ocean waters can offer abundant prey resources, but these options are often distant, patchy and unpredictable. The nearshore typically offers seabirds a smaller but...

Fewer breeding pairs this season for Cooper Island guillemot colony
The Cooper Island Black Guillemot colony experiences a major decrease in breeding pairs as long-term decline accelerates. As of July 6, egg laying ended at the Cooper Island colony and the number of breeding pairs is the lowest it has been in four decades. Only 50 guillemot pairs have laid eggs, down from 85 pairs...

Work Worth Doing: Reflecting on 44 years in the Field
The Cooper Island Black Guillemot study was recently mentioned in an Associated Press story by Seth Borenstein about researchers who “accidentally” began studying climate change. A number of scientists measuring a biological phenomenon have encountered unanticipated effects from climate change and understood those effects were more important, both biologically and politically, than what originally motivated them to...

The First Egg!
The first egg of the 2018 breeding season was laid on June 24th by White-Black-Gray. She fledged from Cooper Island in 1995 and has lived through a period of major climate change in the Arctic. Hoping she, and the other 150 guillemots in the colony, have a successful breeding season! The somewhat bad news is...

The first field report of the 2018 season
Great to be back on Cooper island after two intense weeks of preparation in Seattle and Utqiaġvik. Arriving on the island begins an even more intense period as I need to turn the 8-by-12 foot cabin from the overwinter storage shed it has been for the past nine months into a place where I can...
