I took another weekend trip to Lake Artemesia and it was well worth it. The Trumpeter Swan has been there in the past, and apparently just returned.
The usual ducks were in attendance, and a few passerines showed up as well.

Cornell: “Trumpeter Swans demand superlatives: they’re our biggest native waterfowl, stretching to 6 feet in length and weighing more than 25 pounds—almost twice as massive as a Tundra Swan. Getting airborne requires a lumbering takeoff along a 100-yard runway. Despite their size, this once-endangered, now recovering species is as elegant as any swan, with a graceful neck and snowy-white plumage. They breed on wetlands in remote Alaska, Canada, and the northwestern U.S., and winter on ice-free coastal and inland waters.”
