When walking along the shore at Mukilteo, I will often see one or two Murrelets diving for food in the shallows along the edge of Puget Sound.  They are not rare but nor are they particularly abundant.  Consequently, I was rather surprised when at the new ferry terminal to see a large number of them swimming in the water around the new pier structures.  There was a constant stream of them diving down and surfacing again.

I can only assume that something is growing on the surface of the steel posts that support the new loading spans.  The birds would swim up to the posts, dive straight down for a while – presumably as they grabbed the food – and then surface at an oblique angle.  The result was a cycle of birds going down and back up again.  It looked really strange and seemed like something that would stop but there must be plenty to eat as they just kept going.  I figured video was the best way to show what was happening so below is a short clip of them feeding away!
