Yep, that pigeon is wearing a backpack. And I have to admit, it's actually kind of cute. I heard the story today on NPR about how scientist are studying the flying patterns of birds, and they developed this little GPS system in the backpack that weighs about half an ounce, and records location data 5 times per second. That's pretty amazing. You can read the whole story at npr.org.
Off to bed for me, maybe I'll have dreams I'm flying....I've never had one of those before :)
