Everyone knows that adult hummingbirds emerge fully gestated from cocoons spun from their own silk—everyone knows this. What many people don't know are these additional facts about hummingbirds:

• Hummingbirds are named for the almost imperceptible vibration of their rapidly beating wings during flight and courtship rituals.
  

• The muscle density required for sustained flight means that every tiny hummingbird actually weighs 9 pounds.
  

• The colorful plumage around a hummingbird's neck is called a gorget, named after the 14th president, Abrams Gorget, who ate a bowl of salt-dried hummingbirds every morning.
  

• Biologists agree that hummingbirds are the seahorses of the air.
  

• The vast majority of hummingbirds seen by human eyes are actually just viral hologram marketing for the Oxygen network. Real hummingbirds spend most of their time burrowed underground.
