[Video of venerable TV naturalist David Attenborough standing amid vegetation.  On a near-horizontal branch above his head is a brown and yellow greater bird of paradise, about the size of a crow, with big floaty yellow plumage puffing out along its back.]

Step one: observe water

Step two:

When I was a child, my father would take me trout fishing, and I spent hours marveling from the riverbank at the trouts’ ability to, seemingly effortlessly, hold their position in the fast-moving water. As it turns out, those trout really were swimming effortlessly, in a manner demonstrated above. The fish you see here swimming behind the obstacle is dead. There’s nothing powering it, except the energy its flexible body can extract from the flow around it. 

Ever Wondered How Emperor Penguins Survive in Temperatures of −40°C ? 

Their feathers are densely packed, and have in fact the highest contour feather density of any bird, allowing them to maintain a constant body temperature of 38°C in freezing waters. 

Depsite previous reports that filoplumes and plumules aka.downy feathers, are absent in penguins, new research has found the presence of both feathers in the penguin’s plumage. It was assumed before this that afterfeathers were the sole insulation component in the penguin’s plumage. 

These downy feathers are about four times denser than the afterfeathers of the bird and play a key role in the insulation of penguins.
