Nowadays whenever we purchase a new vehicle, we want to know its fuel efficiency. While current models are amazingly more efficient than they were 20 to 30 years ago, they do not even come close to being as fuel- efficient as the ruby-throated hummingbird.
Those ruby-throated hummingbirds that are returning to the United States this spring have to fly anywhere from 500-600 miles across the open waters of the Gulf of Mexico. Remarkably, these tiny birds can make this journey using but 3/40th of an ounce of fuel (fat). To put this in perspective, if a 170-pound man or woman could fly like a hummingbird, it would require storing 85 pounds of fat! Now that is fuel efficiency!
