then do they have to slow their metabolism at night in order to sleep and still wake up in the morning without having starved to death? i just spent a little while watching about 6 of the little suckers fighting over my feeder (too funny) and gosh they use so much energy up on that!!!
it's a random question i know, but i think it would be interesting to know the answer. :)

to the guy who said they don't sleep - i thought every living organism had to sleep to recharge... you seriously think it's like the girl in weird science who never stopped moving around??? lol

Because of their high metabolic rate and the cost of their active flight, hummingbirds spend on average 70% of their time perched (often preening). They are very curious and will investigate brightly colored objects as potential food sources. They are diurnal and forage throughout the day, with peak activity at dawn and dusk.
In order to save energy during cold nights, hummingbirds will go into torpor. During torpor their body temperature decreases 20 to 30 degrees, their heartbeat can go below 50 beats per minute and their breathing becomes irregular. Most bird species are too large to use torpor to save energy since it would take too long and use too much energy to warm back up. It can take hummingbirds as long as an hour to come out of torpor, and if they are disturbed they cannot immediately resume normal activity.

Since hummingbirds will fly across the Gulf of Mexico in their migration (a feat that takes between 18 and 24 hours) I believe your information about them having to eat every 15 minutes is inaccurate.

A humming bird's metabolism is so high because of how fast he has to flap his wings to stay aloft all day.It takes lots of calories to maintain that kind of motion.So my best guess is that because they don't have to flap (if you can call it flapping) their wings when they sleep they don't burn all those calories at night,and their metabolism slows down during that period.
