After deriding people for chasing after the eared quetzal for their birding lists, I went chasing after — the eared quetzal. This bird is a very rare visitor from the Sierra Madre mountains of Mexico. Every fifteen years or so it shows up in the madrean sky islands of southeastern Arizona. This year three of them have been spotted in the Chiricahua Mountains in Cochise County, and I saw two of them — a remarkable addition to my Big Week list.
