This beautiful piece of work is a production of the new Disney Nature documentary label, which marks a revival of the Walt Disney Company's historical commitment to large-scale factual filmmaking about the world in which we live. Who knew it was so hazardous to be a flamingo? The film focuses upon the flamingo community that lives on the salted waters of Lake Natron in northern Tanzania, and gains its pink plumage from minerals in the algae on the lake's surface. Through the year, the flamingos make mass migrations to optimum spots for feeding and breeding that are no less hazardous than the trips undertaken by their polar cousins in March of the Penguins. For one thing, there are the predatory Marabou storks stationed along the way to pick off little flamingos that don't move fast enough, or can't, because the salt from the lake water has hardened into cumbersome bracelets at their ankles. The Crimson Wing is as baffling, addictive and fantastical as any in-depth analysis of nature's ways, and considerably more gorgeously-crafted than most.
