I think this is a northern harrier, but that is just my best guess using my ipad bird app
These were taken at Coyote Hills regional park on the eastern shore of the San Francisco Bay. He or she was crusing over the marsh looking for supper I think. I am still trying to get the hang of the right settings with this camera both for shooting and post as you can really tell from the noise in the 3rd shot. Some of that is pollen floating in the air too however. The bottom line is that I'm having fun though, and that's what matters!
