raptor of some kind?

we went bike riding on the sf bay trail today, as per usual weekend plans, this time doing the san mateo => san carlos portion of the trail. we saw lots of marsh birds, shore birds, raptors, and sea birds. this is some kind of hawk or raptor that was hunting the marsh flats and spooking jackrabbits. plz ignore the graininess of all of these as i still continue to leave my ISO set super high and not check it until halfway thru shooting when I wonder why my shutter speed is running into HI again. :(((
