Lake Hennessey - Napa County

Today my regular Sunday bike ride took me to Lake Hennessey as the list-serves had said that tundra swans were present. I rode out the north shore trail past the railcar bridge and there was a lot to see. There was quite a bit of waterfowl and I'm sure a few birds that could have gone on my Napa county list, but I had no optics to confirm my guesses. There were no swans but I saw what were probably Bonaparte's Gulls, a Barn Owl, Ring-necked ducks and what was definitely an adult Bald Eagle.
