puffinuria

Petrels are the most aerial and oceanic of birds, yet in the quiet Sounds of Tierra del Fuego, the puffinuria berardi, in its general habits, in its astonishing power of diving, its manner of swimming, and of flying when unwillingly it takes flight, would be mistaken by any one for an auk or grebe; nevertheless, it is essentially a petrel, but with many parts of its organisation profoundly modified.
