The highlight of a trip to Ano Nuevo State Park is supposed to be the sight of hundreds of Elephant Seals. But when Carol and I visited the park today, what I enjoyed most was seeing Bank Swallows building nests in a bluff high above the beach. I watched through binoculars as the swallows whizzed around the bluff, and in and out of their nesting holes. Every once in a while, a small shower of sand would come out of one of the next holes, presumably because one of the birds was doing some excavation work inside the hole.
