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! For comparison, a U.S. These diminutive birds weigh only about 4 grams-or. ![]()
