A hummingbird weighs less than a penny

The Bee Hummingbird is the smallest type of bird in the world, weighing in at under 2 grams. To put that into perspective, a penny weighs 3-4 grams, depending on what year it was minted in. Hummingbirds can reach up to 20 grams in weight, but the Bee Hummingbird sits at under 10 percent of that weight at 2 grams. While it weighs less than a penny, the Bee Hummingbird is still larger in size than its coin counterpart, with hollow bones and light feathers allowing it to weigh so little.
