Observation: Swinomish Indian Tribal Community had a special guest at the Administration building. This bald eagle Haliaeetus leucocephalus was spotted by a tribal employee Tino Villaluz, the Hunting and Gathering Program Manager. The eagle was just sitting in a tree in front of the Admin building. It looks to be a leucistic bald eagle based on the light coloration of it's feathers.
LEO Says: Leucism is defined as a partial or total lack of eumelanin and phaeomelanin in the feathers as a result of inherited disorder of the deposition of these pigments in the feathers. (Grouw, 2006) There is documentation of a resident leucistic eagle in Klamath Basin NWR, Oregon, for several years that eagle has nested locally. (Liedtke, 2017)
