Another waterbird of note that has traditionally nested at Lost Lake is the Black Tern, a Category 2 candidate for listing under the Endangered Species Act, and a bird-at-risk on the Washington Gap Analysis list. According to the Seattle Audubon Society (2008), Black Tern numbers have “decreased since the 1960s due in part to the destruction or degradation of much of their breeding…habitat.”
You may see these black and silver birds swooping to pluck food from the surface of Lost Lake or foraging in flight as they seize flying insects from the air. In order to nest, the Black Tern needs habitat with extensive cover vegetation as well as open water. Like the loon, the small and graceful tern nests on floating debris or near the water, making the Lost Lake non-combustible motor rule a key factor for successful nesting for both species.
