Black Tern on fence post

I was so happy when I came across a couple of Black Terns perched on fence posts. Usually, they are flying at top speed in every direction possible, including dive-bombing! I was sitting in the "safety" of my car : ) Taken along one of the backroads SW of the city, on 12 June 2014.

The Black Tern is a small, dark, graceful Tern, found in freshwater marshes. It eats insects as well as fish. In breeding plumage it has a dark head and chest and gray wings.
