ISABELLA: Sylvie, Lucas and I
are visiting the wildlife sanctuary with Fran.
We are going to be talking about birds' nests,
and I brought a couple of birds' nests to show you.
So what do you see in this one?
ISABELLA: There is, like, grass and straw and mud and leaves.
The other nest had string, plastic ribbon and grass.
It's mostly made of junk--
like stuff that people throw away.
I want you to pretend that you're a bird this size.
What kind of stuff would you use to build your nest with?
ISABELLA: Lucas is using grass
and forming it into a round shape
to make his nest.
LUCAS: This is where the bird will sit.
I just found this-- it's man-made.
I'm going to put it in my nest.
Milkweed!
ISABELLA: This is milkweed, and it feels like silk,
and we think it would be really good.
I am forming grass into a nest shape.
It is made of milkweed fluff and dead grass.
I'm layering the bottom with sticks
and I am using dried grass.
ISABELLA: Sylvie is putting in milkweed fluff, too.
SYLVIE: Ah, that will look good.
My nest is comfortable.
It is very comfortable.
ISABELLA: Look around for things
that would make a good bird's nest.
Then try to build your own.
