Until this most recent study, scientists drew their estimates by counting breeding pairs. However, this means previous counts missed non-breeding penguins.

“Non-breeding birds are harder to count because they are out foraging at sea, rather than nesting in colonies on land,” Louise Emmerson, a seabird ecologist with the Australian Antarctic Division, says in a press release.

Using a combination of aerial and ground surveys, as well as automated camera images, researchers were able to collect more accurate population counts over several breeding seasons and revise their estimated totals.
