Smallest Bird in Existence: Which is it: the Bee or the Bumble Bee Hummingbirds?
Depending on the source, either the Cuban Bee Hummingbirds or the Mexican Bumble Bee Hummingbirds are listed as the Smallest Bird Species in Existence.
- The smallest and lightest known living bird ever recorded is the Cuban Bee Hummingbird.
- This tiny, brightly colored bird weighs less than a Canadian or US penny and because of that they are often referred to as "Penny Hummingbirds" or "Penny Birds."
