On Tuesday, I spotted a heron roosting in a tree, on my way to work. A closer look revealed several more, for a total of four of them, and that they're black-crowned night herons. I can find two in this picture, I think it took another angle to spot the others.

I meant to bring a camera with a bit more lens, today, and forgot, but the herons were still there (I counted five). This is between the BU boathouse and the rotary, on Memorial Drive.
