This post is a question for whoever might be able to help me out. I was walking along Alameda Creek and I saw various sets of these devices along the levee banks at different locations. I was curious as to what they could be. They looked like they would float so I wondered whether they are designed to start at the bottom of the track and then float up as the water levels rises. Perhaps this then reports back to some control location so everyone knows the level of the creek? However, that is just a guess. Does anyone know the real story?
While I was down by San Francisco Bay, a bird came flying towards me and I took some shots purely for panning practice. I thought it was a gull or a tern so I was only bothered by trying to get steady shots. However, when I look at it, the bird has the beak of a raptor. I have no idea what it is. Does anyone out there know?
