Ever wonder how penguins are able to survive in those bitterly cold Antarctic winters? As this time-lapse video demonstrates, it all comes down to their huddle patterns.

BIRDS
These Antarctic birds might look cute and huggable, but you might want to give them a wide berth after mealtime.
Humans aren’t the only animals that keep larders of food.
Lots of beach-goers find seagulls annoying, but usually the only harm they do is snatching away poorly-guarded snacks. On one particular beach, though, scientists have found that some gulls have a much more aggressive and grisly way of getting their meals
The birds keep their food-finding tools safe while they're eating or foraging.
The seagull—scourge of the beach-blanket snacker, parking-lot pest—is nobody's favorite. Birding guides will tell you that seagulls have no natural enemies, which is mostly true. But once in a while, somebody’s had enough.
