Aptenodytes forsteri G.R.Gray, 1844

The emperor penguin is the tallest and heaviest of all living penguin species and lives exclusively in Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg. Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches.

"Emperor penguins are the largest sea birds in the Antarctic, standing 101 to 132 cm tall." Range-only; value is the midpoint. ADW's own length field carries the same 101-132 cm, so the standing-height wording is ADW's; Antarctic agency pages (AAD, BAS) checked and state weight but no height.
