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 breeding is important this summer as birds may be able to have their young fledge before the major loss of sea ice predicted for August.
