Wild Kratts
Dynamics of Purple Martin Flight
Clip | 2m 51sVideo has Closed Captions
While the purple martin flies, the Wild Kratts analyze the dynamics of flight.
As the Wild Kratts watch the purple martin fly, they break down the science of the bird's flight. But when the bird lands, they notice he is no longer black. Aviva explains that's because of light refraction and with the use of a prism, explains the concept.

Give me some more observations.
KOKI: Wings are for lift.
JIMMY Z: Tail moves like a rudder.
CHRIS: Quick wings flaps to gain speed.
MARTIN: Tuck wings for rocket speed.
KOKI: Spread wings... JIMMY Z: And tail... CHRIS: To slow down... MARTIN: And land...
BOTH: Right in front of us!
Bros, that'’’s not the purple martin.
It'’’s not?
No, it'’’s not purple, it'’’s black.
But every other feature is screaming purple martin.
The face, the wings, the beak, the tail feathers.
That'’’s it!
The feathers.
I can explain this one... with this.
With a triangle?
Yeah, Jimmy, it'’’s a prism.
Watch, sunlight is made up of different colors.
We can'’’t see them, but when you shine a light through the prism, it'’’s refracted, meaning it splits and you can see the colors, like a rainbow.
Some bird feathers can do the same thing.
When little or no light is reflected, it looks black.
But if you move or more light hits the feathers, it'’’s refracted and produces color!
ALL: Whoa!
JIMMY Z: That'’’s pretty purplish.
Hmm, I'’’m seeing a lot of blue in that purple.
Well, if it'’’s called a purple martin, the suit has to be purple.
Sorry, no blue or green today.
BOTH: Huh?
Is she serious?
Or just kidding?
(Chuckling) Listo!
Aw, who cares?
Let'’’s just...
BOTH: Activate purple martin powers!
♪ Woo-hoo!
Whoa, check out these wings!
Yeah, this is one slick suit.
And... jet black.
Where'’’s the color?
You'’’re standing in the shade.
Get in the sun.
Yeah, let'’’s refract some light on this martin power suit.
Oh yeah!
I'’’m green!
A green martin.
Wait a minute, I'’’m green.
And so I'’’m still Chris...
I think.
I'’’m blue!
I don'’’t believe it!
This is even better than a purple martin.
I'’’m a blue martin!
Uh, I'’’m a green martin?
Okay, wait a second, I like the green part, but I'’’m not so sure about the martin part.
(Laughing) Funny, bro!
Any color martin'’’s are awesome.
Okay, being a martin, this is going to be one confusing creature adventure.
(Chirping) Purple martins on the move!
Wait up, bro!
