Now there’s a penguin that can molt and melt.
Penguin feathers have two parts to them. At the bottom they are soft and downy and at the top they are stiff. The downy layer is fluffy and provides an airy area to act like insulation which is shielded by the stiff ends. They can lose this a bit in the water since it presses the feathers to them. Out of the water though they have an advantage over seals from the wind chill with their shell of feathers, seals will retreat to the water when the air gets too cold. When a penguin gets too hot it will fluff up the outer feather layer to let air in.
Little Osbourne will return next week so have a great weekend and I’ll see you on Monday!
