The smallest bird in the world is a Bee Hummingbird, weighing 1.8 grams and standing 5 centimeters tall. This miniature bird lives in Cuba, and unlike many of its interesting animal brethren, isn’t endangered, but its population is dwindling; which could potentially pose a problem for many species of flowers that depend upon the Bee Hummingbird for pollination.
The Bee Hummingbird eats up to half of its own weight in food and drinks 8 times its weight in water per day; energy needed to fuel wings that beat 80 times per second. Their tiny eggs are about the size of Tic Tacs and are laid, usually two at a time into nests suspended by spider silk. On an interesting side note, they have very few feathers; about 1000, as compared to other species of birds that can have up to 25000 feathers.
