A great movie guide for the PBS documentary. I use it to introduce Costa Rica and the parrot smuggling issues (and impacts in the U.S.) before reading Robo en la noche in my Spanish classes. This guide, however, is in English, and can be used in a biology/zoology class, as well as in the Spanish classroom. There is no answer key, however, a list of the bird descriptions is provided. Also makes for a great sub plan!
