Great Blue Heron

A Great Blue Heron convention on 3 March 2020 at Woodard Bay near Olympia. We count about 30 birds in the photo, but we estimated 50 altogether. The birds are on an abandoned logging pier, which is no longer connected to the mainland. The pier is controversial. On one hand, birds, like these herons, use the pier to roost. More amazing, in the spring, hundreds of bats roost under the pier and make nightly migrations to Capitol Lake to feed on insects. On the other hand, the pier is an unnatural structure. Worse yet, it is heavily treated with creosote, an oil distilled from coal tar, which is a source of pollution. I think there is talk of treating the pier with some kind of creosote blocking agent.
