The 19 million acre Yukon Delta National Wildlife Refuge and surrounding region provide one of the most important breeding areas for birds in Alaska.  An estimated 1,000,000+ ducks and shorebirds, 500,000 geese, 100,000 Swans, and 10,000’s of grebes, loons, and cranes call this region their home during the summer.  These birds include most of the Alaska breeding population of Black Brant, Emperor Geese, the threatened Spectacled Eider, Cackling Geese, and Bar-tailed Godwits.  Bar-tailed Godwits return to this region after wintering mostly in New Zealand and after completely one of the longest non-stop migrations in the world of some 7,500 miles in about 11 days.  Dr. Mark Lindberg will discuss the birds of this region based on his 10 years of experience on the Delta dating back to 1990 and 4 years of photos he compiled between 2018-2022. He recently donated these photos to the US Fish and Wildlife Service public domain for education and conservation. He will emphasize bird ecology and conservation in his presentation with some ID tips as well.
