This week, Dave and I attended the second movie in The Future of Nature Film Series sponsored by The Nature Conservancy. The Messenger was presented with support from Harvest Capital, Orr & Reno and Eastern Bank and held at the Red River Theatres in Concord, New Hampshire. The Future of Nature Film Series is a great opportunity to delve deeper into an environmental topic by watching a film, and then engaging in a Q & A session with a panel of experts.

The movie touches upon a host of topics related to birds across the globe including migratory patterns, hunting traditions in France, songbirds role in the origins of music in Germany, and threats to their existence. Songbirds have shown a drastic decline over the past 50 years, almost 50 percent in North America, according to monitoring studies. Among the reasons for songbirds decline presented in the movie are mortality from building strikes, light pollution, pesticides, habitat destruction and predation by cats. I learned that songbirds migrate at night, so that excessive lighting in urban areas can disrupt their migration patterns. I also learned that neonicotinoids, a pesticide known to adversely effect bees, have been detected in surface water near farm fields that have previously grown plants that were derived from neonicotinoid treated seeds. It is suspected that this pesticide may be killing aquatic born insects, a major food source for many birds.
