This is the first of a new generation of nature documentaries from Disney and they picked a VERY difficult topic to cover. Instead of the usual locations like jungles or plains, this one is filmed in the most hellish place in Tanzania--near the Kenyan border in a region made toxic to most life by volcanic ash. However, surprisingly, 2.5 million flamingos return to Lake Natron each year- -despite it having a pH of 10.5 and being made up of a mixture of ash and salt. The film follows the flamingos for a year--as the return to do their courtship rituals, lay and hatch eggs and then grow into adulthood. It's all quite lovely with nice cinematography yet Disney chose not to release this to theaters--though it would have been lovely to see on the giant screen.
My only reservations are that kids might be a bit shook up because nature is pitiless and you see a lot of flamingos die. Also, biologists might dislike how the narration often becomes much too prosaic and not exactly scientific. Still, the overall effect is breathtaking and if you see it, try to see it on as large a TV as possible.
