Long-term Data Collection Serves Many: Cooper Island study aids graduate students studying climate change

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...

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,...

The nearshore typically offers seabirds a smaller but...

Hoping she, and the other 150 guillemots in the colony, have a successful breeding season! The somewhat bad news is...

Earliest breeding season in 42 years

The record setting snowmelt in Barrow this spring has resulted in the earliest breeding season for the Black Guillemots on Cooper Island in the 42 years the colony has been studied. Median date of egg laying (when 50 percent of the nests have eggs) was June 16th. Three days earlier than the previous record – set in 2015. Early...
