Size
Egg size tends to be proportional to the size of the adult bird, from the half gram egg of the Bee Hummingbird to the 1.5kg egg of the Ostrich. Kiwis have disproportionately large eggs, upto 20% of the females body weight. This evolutionary trait results in kiwi chicks that can emerge from the nest days after hatching, ready to start foraging for food.
