Moths

Apparently, Moths can use some sort of ingrained sense not only to navigate, but to detect and take advantage of wind currents. According to this article from NPR, not only can these tiny little marvels navigate using some kind of internal compass, but they can also detect wind speed and direction and use that information to select the altitude with the most favorable winds.

Amazingly sophisticated, for such a small animal. Makes me feel a little sad that the cats will occasionally eat one of these little silken marvels.
