Cool. Never imagined hummingbirds sleeping upside down. Thanks for sharing.

Hummingbirds go into torpor to save energy, protect themselves from dehydration, lack of food, or to rest after long migratory flights. It appears that they are dead but they are not. Heart rate, normally 500+ beats per minute, slows to 50 or so; breath rate also. It is a state between deep sleep and hibernation. Don't disturb them, or assume they are dead, just leave them alone and they will naturally wake up and move on when they are ready.

They sleep upside down it slows their heart down.

I had the pleasure of watching one of my hummers taking a nap last week it was great

must be so hard to resist not to touch that fluffiness :D

so rad seeing them in torpor!

Fantastic! Beautiful bird!

Absolutely Incredible️! U r indeed fortunate to be so Upclose to this Tiny Beautiful Bird & film it in its most Relaxed Sleeping Flexible Posture, Just Brilliant & Thank U for sharing️

They usually go "vmmmmmm." This one's going "zzzzzzzzzzzz." :D

So this is something you don’t see every day! Thanks for sharing. I didn’t know they can sleep upside down, now I know. :-)

The hummingbird needs to wear a sign “Do Not Disturb” on him!

Little Hummingbirds from Transylvania.
