smart animals

From the BBC, my favorite source for critter news, two 21st-century entries in the venerable "sagacious animals" genre**:

1. "Wild" Australian dolphins develop "tail-walking culture"!
It seems weird to call a dolphin that lived close enough to humans to get trapped in a marina lock, rescued into a dolphinarium, then subsequently released to be closely observed by a team of scientists "wild." We humans sure have strange cognitive needs, don't we?

I never got around to seeing Happy Feet, but I can see this story being captured by Hollywood and genetically modified into a break-dancing cetacean flick. Or an even more anthropocentric version of Ratatouille, in which animals don't just want to become human, but aspire to be the funhouse version of themselves that humans want them to be.

2. Magpies can recognize mirror reflections of themselves!
And apparently they don't mind having random stickers stuck on their bodies as long as they can't see them.

** I'm using the term "sagacious animal" pretty loosely here, to refer to the kind of sometimes scientific, sometimes sentimental, sometimes a bit of both stories about smart animals and their funny ways that you'd find in the news and other popular sources. Harriet Ritvo, author of the wonderfully learned Animal Estate: The English and Other Creatures in Victorian England, gives a much more rigorous account of the concept of "animal sagacity" in the history of science:

... well into the last part of the nineteenth century "sagacity" was the standard term for intelligence demonstrated by animals. An individual animal or species might be described as "intelligent," but the term "intelligence" itself was generally reserved for strictly human capacities. (Conversely, if "sagacity" was attributed to human beings, it often had an ironic or less than flattering connotation.) The phrase "animal sagacity" in the title of a book or article often signaled an abstract discussion of instinct or intellect, the kind of discussion that might conclude by appreciating the intelligence of apes. But in the more common usage of naturalists, sagacity indicated not the ability to manipulate mechanical contraptions or solve logical problems, but a more diffuse kind of mental power: the ability to adapt to human surroundings and to please people. A somewhat circular calculation made the most sagacious animals the best servants. So dogs might not only rival apes in the mental competition, but surpass them - closest to their masters in mind as well as in domicile.

"The ability to adapt to human surroundings and to please people" - that may not be the official measure of animal cognitive capacities in 21st-century science, but it certainly still seems to be a potent force in the popular/pop-scientific imagination.
