Out My Backdoor: 4 Parts Water, 1 Part Sugar—a Special Fuel
By Terry W. Johnson
The bird that controls the air space over our yards throughout spring and summer is the ruby-throated hummingbird. Although it is so small that 10 can be mailed for the price of a first-class stamp, no other bird can threaten its aerial superiority. As is the case with supersonic aircraft that coarse the skies of the world, this feathered dynamo operates on a high-energy fuel. In the hummingbird’s case, the fuel is sugar.
