The Humboldt Bay Wildlife Refuge is located on the coast of Northern California about ten miles south of the city of Eureka and just off Highway 101.
This was shot with my Olympus E3, Zuiko 70-300mm lens.
Young Swallows sit on a fence rail and try to get the mother bird to feed them even though they have fledged from the nest. They would exhibit this behavior for a couple of seconds and then just sit there. I noticed that they did this every time a certain bird flew over the marsh water headed toward them. After a while, I realized that the mother bird was flying low over the water trying to teach the young birds how to catch insects. I watched for over an hour and she never did feed them. I was able to get this shot after about twenty tries.
