Great Blue Heron?

Today Mom, Rachel and I were meeting Dad for lunch and took a wrong turn. We pulled into an apartment's parking lot to try and figure out where to go, and saw what I believe to be a great blue heron:

He or she (apparently males and females look the same) was just hanging out there. I wasn't close enough, so I had to take this picture with the digital zoom, but you get the idea. I had no idea these guys live in San Antonio, but sure enough, we're well within their range.
