[serene music playing]

MAN: Hummingbirds flap their wings

around 50 times a second, allowing them to feed in place.

It's like treading water, but in mid-air and at high speed.

It takes a lot of energy.

If they don't consume double their body weight in calories

every day, they won't survive.

this hummer doesn't stop.

Most birds take cover in rain, but hummers do the. opposite.

The cooler temperatures increase their metabolic rate,

and every drop of nectar is a matter of life or death.

As the storm clears, another male horns in on his territory.

He defends it with all he's got.

Success.

A good flower is worth fighting for.

Not just for food, but for love.

Nectar is a girl's best friend.

The gift of a flower will make him

very popular with the ladies.
