What could this odd couple have in common Bee hummingbird Measures about the size of a bumblebee
Giraffe Stands tall enough to look into a second floor window
They both hum Hummingbirds are so well known for their hum it's how they got their name Their fast beating wings produce the sound you hear In fact the bee hummingbird flaps its wings up to 80 times every second when it flies Besides making that distinctive hum those super speedy wings also help hummingbirds do something no other bird can do fly backward
mmmmm Hummmmmm Giraffes are also hummers They can be heard humming away very quietly throughout the night But scientists aren't sure why Some think it may be a way for giraffes to communicate with the rest of their herd Or the humming could simply be a sound that's made as they sleep similar to how some humans snore
