This Curlew was stalking the shallows at the Mission River Preserve. Recently, the newspaper had an article about chickens (and indeed all birds) being descended from dinosaur stock. I thought about how patient, persistent and even ruthless they can be in pursuit of food. The determination of these tiny and beautiful creatures is quite admirable in a perverse sort of way. However, when I imagine what they would be like if they were every bit as ruthless but the size of an SUV, I have to admit that I'm quite relieved that dinosaurs are extinct.
