Penguins generally only lay one brood; the exception is the little penguin, which can raise two or three broods in a season. [ 64 ] Penguin eggs are smaller than any other bird species when compared proportionally to the weight of the parent birds; at 52 g (2 oz), the little penguin egg is 4.7% of its mothers' weight, and the 450 g (1 lb ...

Diving birds, however, do not have this constraint because open water can accommodate harder landings.

[10] Also thought to provide ballast is the swallowing of small stones by penguins. Although heavy ...

Even though they live in large colonies, emperor penguins are the least common Antarctic penguins. Scientists estimate anywhere from 265,000 to 278,000 breeding pairs are left in the wild.

Adult emperor penguins are 110–120 cm (43–47 in) in length, averaging 115 cm (45 in) according to Stonehouse (1975). Due to the method of bird measurement that measures length between bill to tail, sometimes body length and standing height are confused, and some reported height even reaching 1.5 m (4 ft 11 in) tall.

Penguins evolved their wing structure to become more efficient underwater at the cost of their efficiency in the air. [ 28 ] The only known species of flightless bird in which wings completely disappeared was the gigantic, herbivorous moa of New Zealand , hunted to extinction by humans by the 15th century.
