While driving back to Tucson from Phoenix on Friday, I saw what I thought was black smoke in the sky. "Something's burning," I told Gaby. Then the "smoke" rapidly changed direction. "Wait, those are birds!" I shouted. This was a massive flock that seemed to go on forever. As we approached, they flew right over us and eventually paralleled us for a while. Gaby took some video on her point and shoot camera right after I first saw them. I exited the interstate and Gaby and I took these photos. It was truly amazing! These photos show only a fraction of the whole spectacle. There were 1,000's!
