Seen to fly off nest and return in a few minutes. Settled down in nest very quickly.
觀察細節
Following up on Sheryl's tip from yesterday that there might be nesting ravens near the trestle. There were two nests on adjacent girders seen from the Wallingford side of the creek and the north side of the trestle. After 15 minutes of watching the nests a raven flew off, perched briefly on the trestle and flew away. It returned after just a few minutes. I saw no sign of food or anything to suggest it was feeding nestlings. It seemed to settle down into incubation pretty quickly.
