Snowy egrets, which stalk but also hunt by shuffling their yellow feet to disturb prey, seem to me to prefer upstream pools. The great egret more often stalks the broader tidal reaches downstream. Is this impression correct? Is aquatic vegetation important in protecting small fish from these and other predators, such as kingfishers?

This small spider, hidden under leaves, is named for its color. This and others ID'd by the wonderful Eddie Dunbar (www.bugpeople.org) on a bug hunt. It would be great to get a real catalog here!
Unidentified large blue dragonfly, resting on cow parsnip stem near willows, S. bank Cerrito Creek near Pierce St. It would be great to catalog the wonderful variety of dragonflies along the creek, and watch their behavior!
Patrolling sunny creek bank above ford, pausing on aquatic vegetation. ID uncertain -- several dragonfly species look similar.
These are common; date is date of photo.
