A hummer's metabolic rate, the rate at which it uses energy, is the highest of any warm-blooded vertebrate except the shrew. Hummingbirds consume half their weight in sugars each day. In migration, they fly 500 miles across the Gulf of Mexico twice each year. The bird's sparkling beauty, amazing antics at sugar-water feeders and tolerance of human activities certainly makes it one of Oklahoma's favorite "Watchable Wildlife" species.
