I spent time this afternoon watching Caspian terns fishing off the beach next to the Coupeville-Port Townsend ferry. This guy was successful.
Later, when I was wandering the backwater nearby, I apparently got too close to the terns’ nesting area. The sent out the call, and five hovered around squawking while one repeatedly dive-bombed me. Never got close enough to poke my eyes out, but I got the message and left.
