Check out some wonderful work from National Geographic photographer Anand Varma. Interesting details:

A 2013 University of Toronto study concluded that if hummingbirds were the size of an average human, they’d need to drink more than one 12-ounce can of soda for every minute they’re hovering, because they burn sugar so fast.

Kottke adds,

some hummingbirds can beat their wings 100 times in a second and can sip nectar 15 times per second. I also like the locals’ name for the Cuban bee hummingbird, the world’s smallest bird: zunzuncito (little buzz buzz).
