How owls developed stealth technology

How owls developed stealth technology

How owls developed stealth technologyThe Guardians of Ga’Hoole, Jareth the Goblin King, and Harry Potter’s

messenger owls have the power of creeping up on people. So do owls

in real life,

due to the design of their wings and feathers.

Owls are the bird of choice for the freaky supernatural beings.

They look cool.

They have the freaky-head-turn thing going for them. Mostly they

evoke the otherworldly because they can move silently through

the air; sneaking up

on their prey from out of the darkness . . . RIGHTNOW!

The owl’s wing is broad and rounded compared to that of other birds,

which makes for less flapping, and a quieter ride through the air.

That reduces some sound, but an owl is quiet even compared

to other birds

when they glide. It’s more than just a difference in wing


It’s the fact that owls are fully upholstered in order

to maintain silence.

How owls developed stealth technologyThe inside of

music studios, concert halls and movie theaters is covered with blocks

of fabric.

These muffle sound and prevent echoing. An owl’s hard surfaces,

specifically its legs and feet, are covered with soft feathered that

muffle noise.

It’s the wing feathers that are really counterintuitive, though.

Most people,

when designing something that makes little noise,

will make it as sleekand rounded as possible.That turns out

to be a mistake. A sleek, streamlined thing won’t have

any extra parts banging off

each other

or creaking in the wind. As we’ve seen before, though, it will have turbulence.Turbulence is moving air and moving air makes noise.

On the front of the owl’s wing are feathers shaped like combs.

The teethof the combs lined the leading edge of the wing,

and like the bumps ona whale’s flukes, break up the stream

of air moving over the wing.

At the other side of the wing, the feathering is uneven, creating

a fringe-like back edge. The combination takes the air that would

all splash off the wing at the same time, and instead lets it out in

isolated dribbles.

The result? Evolutionary advantage. Silent death. The ninjas of the

animal world. All kinds of ancient myths. Supernatural mystery.

And David Bowie. I don’t know how the last one fits in, either.
