(Gasping) I'd say about five different wolves.

What?

What part of the track is telling you that?

Three silver ones, two black ones... What?

Where do you see that?

And one white one!

How in the world can you tell that from these tracks?

Well actually, you kind of have to look at the big picture.

Whoa!

Now, that's a wolf pack!

Well, who would've thunk it?

Maybe the best way to find wolves is just to be out in the wild talking about wolves.

Come in, Tortuga.

This is Little Boy Who Cried Wolf calling Tortuga.

Little Boy Who Cried Wolf telling you we found wolves.

Forget it, Martin.

Wolves on the move!

Okay, check that.

We're running with the wolves!

(Cawing) And we're not the only ones!

Ravens!

Ravens are following them too!

MARTIN: It helps to have wings to follow wolves because they have a fast pace, called a lope.

A wolf can lope along all day long, covering 100 miles with hardly a rest.

Now that's what I call a marathon.

Hey, what do you call it when they pick up the pace even faster?

More tiring?

A chase!

An all-out run.

Hoohoo!

They're after something.

(Growling) (Pack howling) (Panting) Where do they get that kick?

I know they can marathon all day and then sprint when they need to.

(Rhythmic thudding) Do you hear a horse?

Sounds bigger than a horse.

Sounds like it has antlers.

How can you tell that?

From that moose charging towards us!

(Screaming)
