WATCH: Hummingbirds snore too! And this is what they sound like...
With their ability to hover like a helicopter and dart about the air like a tiny missile, hummingbirds are some of nature's most agile and superb flying creatures.
But a day of zipping about the air while beating their wings at an insane rate takes its toll on those tiny little frames and it certainly shows in their sleep.
While they're miniscule compared to humans, hummingbirds have one thing in common with us - they snore.
The phenomenon was discovered by scientists in Peru and captured on camera by BBC One for a television programme called Super Cute Animals.
Here's what it sounds like:
Even though it sounds like the whistling made by a falling bomb or mortar shell, there's no doubt that the snore adds to the cuteness of the hummingbird.
It definitely beats the sound of my snoring!
