I've been so lucky to see oystercatchers lately.
They're some of my favorite birds. They're about the size of a seagull, with black bodies, Silly Putty colored feet, and bright red tube-shaped beaks.
They can be incredibly difficult to see against the dark rocks where they feed. Fortunately, they often cry out just before they take flight. By following the sound, I can often spot them just before they leave their current rock for a different one.
A few days ago, I had the pleasure of seeing them fly over to the sandy beach near the Sutro Baths, where they stood out clearly against the light sand.
I could watch them for hours.
