An old friend returns for a new picture

This past summer the Cooper Island field camp was thankful to have a return visit from photographer Joe McNally. Joe has been taking photos longer than I have been studying Cooper Island Black Guillemots and his website shows both the quality and scope of his work. His visit in 2001 took place before we had...

Birds on Nests During Incubation

By George Divoky The Black Guillemots on Cooper Island continued to show signs of a turnaround from the poor breeding season of 2018 as egg laying and incubations has occurred in over 75 nests this year, compared to only 25 last year.  The breeding population saw the recruitment of 20 birds that had fledged from the island...

A visit from a long-term friend of Cooper Island

Field Season Update: 75 active nest sites

Polar bears caused me to get a cabin on Cooper Island in 2003.

The first week of the 2019 field season found...
