At first I thought I was imagining things. Hummingbirds in the middle of Mexico City? Then I looked again. It was definitely a hummingbird feeder hanging in the window. I kept staring, hoping they would come back. A person appeared behind the curtain, surely wondering why I was staring at their window. I gave a quick wave and a smile to signal, I'm harmless - loco or tourist. Then one of the hummingbirds returned. The first part of the video was filmed in a different part of the city, but I thought the two scenes complemented each other nicely.
