How tall is the average emperor penguin?

The adult Emperor Penguin stands up to 122 cm (48 in) tall. The weight ranges from 22 to 45 kg (49 to 99 lb) and varies by sex, with males weighing more than females. The weight also varies by season, as both male and female penguins lose substantial mass while raising hatchlings and incubating eggs. A male Emperor penguin must withstand the Antarctic cold for more than two months to protect his eggs from extreme cold. During this entire time he doesn't eat a thing. Most male penguins will lose about 12 kg (26 lb) while they wait for their babies to hatch. The mean weight of males at the start of the breeding season is 38 kg (84 lb) and that of females is 29.5 kg (65 lb). After the breeding season this drops to 23 kg (51 lb) for both sexes.
