Red Side made an illustrated comparison of how fast various birds can move, on foot or flying. They start with the slowest birds which are overtaken by faster ones, one by one. I felt sorry for the penguin, who leads things off as the slowest walker, but never gets to show us how fast he can swim. The information is interesting, and you have to appreciate the research that went into this. But the animation itself is way more fascinating. Where are all these birds going? Why are they all going as fast as they can? Is something chasing them? Some are rather awkward even as they are speeding by other species. I found myself waiting for the roadrunner to show up, wondering if a coyote would be watching. The running birds seem to have no knees, and the ostrich has hips hidden way up in its backbone, which makes this frantic chase seem all the more hilarious. Oh yeah, the epic music will have you wondering if there's some kind of reward at the end of this race. -via Nag on the Lake
