Answer:
Humming birds are one of the most interesting animals in the world. Some of them are so small that they are often mistaken for bumblebees. They're known to dive underwater and quickly dive right out while flying, and they eat more than they weigh to prepare their travel across an entire ocean non-stop. On top of all of this, they can be pretty rare depending on where you live, and they're really fun to watch.
Hope this helps you out :)
