Penguins

Adélie penguins in Antarctica nest in large colonies, and these groupings leave behind massive poop stains on the icy landscape — marks that are so large they can be tracked by satellites.

The March for Science was not only for people; penguins marched, too.

There are 3.6 million more penguins in Antarctica than previously estimated.

There may be other explanations for 150,000 missing Adélie penguins presumed dead in Antarctica.

The Galápagos are more than a life raft in Pacific currents — they actually alter the Pacific currents, and in so doing, help feed the islands' residents.

Can perky penguins survive as the oceans grow crowded?

Gentoo penguins seem to gather in colonies, and their large piles of poop help melt the snow and provide "nurseries" for their young.
