We went to Chichen Itza to look at the famous pyramid, and the other Mayan ruins. I was also interested in taking pictures of birds in the area, so I had the bird lens and a wide-angle for the architecture. BUT... I wasn't allowed in with my big "professional lens." Even if my Tamron 150-600 was a professional lens (it isn't), it made no sense to me. It still makes no sense to me... Oh well. While going back to the car to put my bird-lens away, I saw this Masked Tityra in a tree.
