i'm a robin ninja now

so today on the way into my building (on campus), i heard a robin tweety-tweeting, and looked up. sure enough, there were about eight of them in a tree nearby. i'm guessing it's the same group (we were about three blocks away from where i saw yesterday's flock), but who knows. a couple of hours later, when leaving the building, i heard a robin way up in a tree across the street. i'm crazy-alert for robin chirps right now; it's hilarious.
