World Penguin Day

PenguinDay_01

Did you know their collective noun is ‘a huddle of penguins’?
Most penguins like to keep their distance, but if you are an Emperor penguin enduring the coldest winters, you choose to huddle together to keep warm. Keeping cosy also means keeping their feet warm, so they rock backwards on their heels, supporting themselves with their tail feathers, which have no blood flow and so lose no heat.
