I just happened to look out towards Discovery Bay this morning and in my view was a hummingbird on it's way straight up and then plunging down. ?I had no binoculars handy and saw him do this twice. ?The only hummers at the feeder right now are the Anna's, so should I assume this was an Anna's doing this? ?I've only observed the Rufus doing this in the past.
