'Checking
Wikipedia for just how long that trek is:
Quote:
"In late summer to early fall they fatten up for migration. This is important because, as part of their migration, they must fly across the Gulf of Mexico. This feat is impressive, as a 500-mile, non-stop flight over water would seemingly require a caloric energy that far exceeds an adult hummingbird's body weight of 3 grams. However, researchers discovered the tiny birds can increase their body mass up to double with lean mass in preparation for their Gulf crossing. The additional mass, stored as fat, provides enough energy for the birds to achieve the flight."

A hummingbird is three grams in weight? How many aspirin tablets is that?!
But what's the big deal, anyway?
I can do 500 miles sitting down!
