bluebird of happiness in my own backyard! Actually, three of them. Actually, they might have been the Brewer's blackbird, as seen here. They were small, dark blue, shiny, and feeding along the ground. Two were at either end of a shared dandelion stem, like Lady and the Tramp in Lady and the Tramp, having spaghetti. Then the third arrived, and, just as I got my husband to join me at the window, they flew away. Sometimes, that's life.
Or perhaps it was this guy. By Edward Lear.
