Hooray! The Audubon Society of Seattle is awesome! Rachel emailed me this information about the mystery bird after I sent her the photos posted on October 25, 2008.
"The silhouette is that of a heron, and the bill, leg length, wing shape, and general proportions point to a Green Heron...(they are) mostly birds of freshwater habitats, and are uncommon summer residents of Western Washington...they are rather shy and secretive, and aren't birds you see every day, so you were lucky to have one fly over your yard."

I also sent her the picture below, which sealed the deal on the bird id.
The picture is fuzzy because I saw this funny little bird perched, ran like crazy to grab my camera, and snapped a shot mid-stride, just a second before the heron took off. One second there, the next, gone. So the question that sprung to mind was...
Was that the Green Heron or Green Hornet? And that got me to thinking about Halloween costumes and Halloween being just around the corner...and so it goes...that I plan a creepy, crawly garden post for that spooky day...
