As previous population estimates did not take account of 16 of the 46 colonies (see Figure 3), and many previous counts were of poor quality and widely separated in time [11], [12], [23] these historical estimates can not be considered representative of the total breeding population of emperor penguins (previous counts are given for comparison in Table 1).

The paucity of data regarding population status of emperor penguins is largely due to the logistical difficulties of accessing potential emperor penguin breeding habitat in areas of Antarctica that are not in close proximity to research stations.

Two years ago the fecal stain method identified several large, hitherto unknown colonies and nearly doubled our estimate of the world's Emperor Penguins.1, 2 That didn't mean climate change had necessarily increased penguin numbers, but a larger more robust population meant Emperor Penguins were far more resilient to any form of change.

Also, many of the colonies where counts do exist were last counted several decades ago, while other counts rely on estimates from late in the breeding season...
