Snapple Cap Bird Messages

We get free Snapple at work. On the caps, they have their Snapple Cap Facts. Here's some bird-related ones I've seen:

• The only bird that can swim and not fly is a penguin (What about the Flightless Cormorant?)
• The hummingbird is the only bird that can fly backwards
• Pigeons have been trained by the U.S. Coast Guard to spot people lost at sea
• A hummingbird's heart beats 1,400 times a minute
• Penguins have an organ above their eyes that converts seawater to fresh water

I've also seen one that says, "Half of these Snapple facts are false."
