Two red-tailed hawks were circling together over Constitution Avenue and landed on top of the Labor Department. Later I saw the two circling together again, and later still, I saw one perched in a tall willow oak on the grounds of the Capitol. Could we have a pair downtown? This will bear watching.
The Indian Museum wetlands had the usual flock of mallards. I saw that an unusual-looking duck had joined the flock again. My guess is that this bird is a mallard X black duck hybrid. It looks mostly like a black duck, but it has a green crescent running along the top and back of each side of its head.
