This bird's nest is in a small suburban yard. It escaped notice all summer, hidden by the leaves of this "coral bark" Japanese maple. But with the wind and rain and natural course of the seasons, the leaves dropped, and now one's eye naturally tracks to the pretty bark of the tree,
and then to the nest. It's about 7 feet up, and is about 4 inches in diameter. My guess is it belonged to a White-crowned Sparrow.
