I was watching another bird and just absent-mindedly snapped a few pics of this bird b/c it was calling. Can't remember the call. I thought it was one of the many red-winged blackbirds around, but it's not. What the heck is it? Some other kind of blackbird? The setting sun may make it appear redder than it was. The stick looks to be about the right color though.

I was on the boardwalk over a reedy marsh - probably brackish water. It was close to the ship channel.
