Diving ducks play peek-a-boo – or maybe they’re just feeding?  Regardless, one second they are there and the next they are gone.

Pacific Loon – South Jetty, Newport, OR

But they are interesting to watch – how long they can stay under, how far they swim before coming back to the surface, do they have anything in their mouth when they surface, how they interact with other birds and animals nearby, etc

Common Merganser – male – Alsea River, Tidewater, Oregon

When the sun is right you can see a green tint to the male merganser’s head.  His red bill makes him a little Christmasy.  🙂
