Contrast that beastly big bird with a Ruby-throated Hummingbird, which tapes out at 3.75 inches, has a wingspan of 4.5 inches, and weighs all of 3.2 grams. It would require nearly 8.5 hummingbirds, arranged from bill to tail, to equal the body length of the eagle. Whoop-de-do. That's not a staggering factoid. The line of hummers would have to be expanded to 18 birds to bridge the eagle's wingspan - a bit more impressive but still somewhat of a yawner comparofactoid.
But wait - what about weight? This is where comparisons between these two birds get mind-boggling. You would need a pile of 2,128 Ruby-throated Hummingbirds to equalize the scales, if this Bald Eagle was the counterbalance. That is a LOT of hummingbirds! Considering that Ohio's total breeding population of hummingbirds is probably about 50,000 birds, we only have enough hummingbirds in this state to make 23.5 Bald Eagles.
That skyscraper above is the James A. Rhodes State Office Tower, the tallest building in my hometown of Columbus, Ohio. Our string of hummingbirds, if dangled from a helicopter, would have to be held at a height 36 feet HIGHER than the 629 foot tall Rhodes Tower before the last bird would touch the ground.
Wee though they may be, we'd all be in mortal peril if these hummingbirds were the size of eagles. The little nectar-sippers are tough as nails and absolutely fearless. I have no doubt whatsoever that if a Bald Eagle rudely impinged on a hummingbird's turf, the hummer would terrorize the comparatively elephantine and sluggish raptor. And in the world of avian aeronautics, nothing holds a candle to hummingbirds in the stunt-flying department - certainly not an eagle.
