As I climbed the sandy hills at Fort Funston in San Francisco this past May 23, I heard the gurgling croak of a Common Raven. I found it first, hiding up in a pine bough, then followed it when flew off to an open branch.
I was surprised to see quite a few Ravens there and on the beach.
The pair above, shot from the beach looking back up at the sandy cliff, appear to be putting together a nest, but the materials are very strange. Normally, Common Ravens make their nest from branches, so perhaps this is something else, but as can be seen in the bottom image, they definitely were gathering items at this spot.
Later, I came upon a small flock of Ravens rooting around in the sand. This one in particular didn't seem to mind having its picture taken.
An interesting behavior I noticed was their tendency to hop. A bird this large typically walks, and they did do that most of the time, but every once in a while they would move about with a couple quick hoops. It didn't seem quite right. :-)
