Hummingbirds are the Sharks of the Sky 

Quoted from youtuber Captainsparklez also known as Jordan Maron. This quote suggested that as sharks have to keep swimming as to not sink, hummingbirds can't stop flying because they can't land. Of course, hummingbirds can land and Jardon was wrong.

"It just flies forever, it's stuck there like the Sharks of the Sky because most sharks can't stop swimming either. That's probably the first time anyone's ever said that Hummingbirds are the Sharks of the Sky, and I'm going to own up to that."
