Quiz of the Day
  
  
ANSWER: True
     

The hummingbird’s metabolism is so rapid that consumed sugars are used immediately to fuel the body.

Periods of torpor (rest with a low metabolic rate) ease the threat of starvation, but overall, they have to keep eating all day long to survive.

To survive long distance migrations (18-20 hour flight over the Gulf of Mexico), they bulk up their body fat ahead of time.
