National Geographic: Brilliant Beasts: Pigeon Genius

Here's something you might enjoy if you've missed it. On YouTube, they've uploaded the full hour in four parts. You can always download using something like YouTubeDownloader if you want as well. (I presume those of you outside the U.S. have no problems getting on to YouTube. I know there are some challenges with other sites.)
