When hummingbirds are arriving in the north, they are sometimes confronted with unusually cold weather and will enter into a hypothermic torpor to survive. They consume 10 times per gram of muscle tissue than the most elite among human athletes, marathoners and cross-country skiers. They burn all additional weight when crossing the Gulf of Mexico. Cornell University scientists report that in preparation for such flights, they double their body weight with nectar and insects. Some fly nonstop across the Gulf of Mexico in spring and autumn. When the wind blows in the direction in which they are flying, they can travel up to 50 mph. Many of these birds make round-trip migration flights of more than 1,600 kilometers (995 miles)!

They are among the smallest birds, too, with most species measuring 3 to 5 inches long. However, when it’s time to migrate, hummers pack on the grams for the long trip-sometimes doubling their weight. The egg of a hummingbird weighs just 0.4 gram to 2.4 grams. 141 ounce! That’s tiny!
