A Western Bluebird in the picnic area.
At Heron Lake was a pair of Wood Ducks.
A little further up the trail, a pair of White-tailed Kites were building a nest somewhere nearby.
It's nice to see Acorn Woodpeckers on a tree rather than a power pole.
A lot of wetness in the wetlands, looking southwest of Napa.
When I got home, there was a pair of Red-shouldered Hawks in the tree across the street. It seems to be one of their favorite perches, as I have seen them there off and on for several months.
I put up my hummingbird feeder about 3 weeks ago. This is "Flea", a male Anna's Hummingbird. I saw Flea perch on the feeder for 21 minutes straight a few days ago. He has been driving off at least one other male hummer to protect his feeder. Something I learned in the marvelous book "Birdology" is that the bright red/purple color is caused by air in the males head and throat feathers, which causes a prismatic affect when sunlight hits at the right angle. The color is not part of the feathers.
