Ze Frank manages to keep focused on nothing but scientific facts about pigeons for the first two minutes of this video, which are about how pigeons keep their vision steady, with information on how we do it ourselves. After that, it gets into their mating rituals, and it's not quite as wholesome as his surprising last video about bees posted here, but it's also not nearly as juvenile as his earlier episodes of True Facts. He goes on about how surprisingly smart pigeons are, considering their tiny bird brains. Those little brains are more densely packed with neurons than human brains! A pigeon's behavior is not all that sophisticated to us, but within their world, they have super powers that take advantage of opportunities that ensure their survival. At least the pigeons we have today outlasted the passenger pigeon, which went extinct in 1914. This video has a one-minute skippable ad at 3:48.
