Below is another horrible story about the impending extinction of a species.  Extinctions are all bad, but this one has a personal touch, as I had the opportunity to see it in deepest Patagonia.  Santiago Imberti, an ornithologist, friend, and excellent guide, took a small group of us to find many of Patagonia's more obscure bird species, including the Austral Rail, which was presumed extinct but rediscovered by Santiago.  This is another tale of unintended consequences due to the introduction of trout and mink into the lakes of southern Patagonia.  Santiago appears in the well-filmed and produced video.  He's the consummate conservationist and educator and his efforts may yet save this species and others like the Red Knot, a shorebird that spends its winters in Argentina.

The video is 30 minutes long but worth viewing.  You'll see other Patagonian species like guanacos (native camels that were most likely the ancestors of llamas and perhaps alpacas as well), Chilean flamingo, local ducks and fox species, and others.  It's in English :).
