We saw those birds in Venezuela, on a stream off the Apure River. (That would be the Orinoco basin.) I’m not sure they have teeth, but our guide told us the young have claws on their wings. They are called something like guacharaca de agua in Venezuelan Spanish and something like huatsin in English. They are clumsy fliers, and would let us get our canoe right under them. But if we stopped to take a picture, the whole treeful of them would take off.

A quick trip to Bing said they are also called stinky birds in English. Our guide said that they survive in spite of their clumsy flight because they give off an odor most predators find repellent.

Also isn’t there a bird species alive today that has claws on its wings and teeth – a Mexican one perhaps? Can’t quite recall the name of it though.
