Who doesn't love the visual of a waddling penguin? Melissa Brennan, in her early 20's captured this great footage of a well-beaten path in the snow and set up a camera there to record the comings and goings of penguins. It turns out they have an orderly traffic system.
Road conditions are icy in Antarctica, but webbed feet still patter away in this video of a busy penguin highway.  Seems penguins sometimes stop to look left and right before proceeding, either avoiding collisions or making a difficult decision about which way to go next.
