Mild temperatures and good eats keep Pacific brant at Izembek Lagoon in the winter. Most brant have historically flown south to the Pacific coast and Baja for the winter, but eelgrass beds to graze on attract them to the lagoon on Izembek National Wildlife Refuge. Winter surveys by our biologists/pilots have been done annually since 1980, when the number of Pacific brant overwintering at Izembek began to increase. Since that time, the number of Pacific brant staying the winter in Izembek Lagoon and surrounding areas has steadily increased. Between 2011 and 2017, there has been an average of more than 45,000 birds (30% of the population) counted during the mid-winter surveys.
