While certainly an important and well-made film, I found it to be such a downer. Almost in the first frame it has people picking up dead birds that had flown into windows. You won't ever see as many dead songbirds as you do in this movie. It is an important message and birds are a real indicator group to show the shortfalls of modern society, but instead of just showing us the massacre, show us how magnificent birds are so that we are compelled to want to save them. Birds are magnificent and it's easy to show. What this film does do well is to show us the working biologist/ornithologist. For anyone considering working in the field, this is a must-see.
