F/5,6, 1/400, ISO 125.
Walking around Secaucus, NJ I came across a domestic argument between two Tree Swallows. They were chirping so loud at each other, that I thought feathers were going to fly. But in this case, argument came to an end and the tree Swallows went back in to their respected homes. ( My guess the argument was about the color of the house. 🙂 haha )
Interesting Fact: The Tree Swallow—which is most often seen in open, treeless areas—gets its name from its habit of nesting in tree cavities. They also take readily to nest boxes. ( http://www.allaboutbirds.org/guide/tree_swallow/lifehistory )
