Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What are "lights out" programs for migrating birds?

The Big Idea

Every spring and fall, billions of birds fly over cities at night. Bright towers can confuse them. So some cities turn the lights out!

Night Flyers

Step one: Night Flyers. During spring and fall, billions of birds migrate at night. Bright, lit-up towers can confuse them and cause them to collide with glass.

FLAP

Step two: FLAP. In Toronto, a group called FLAP asks building owners to switch off unneeded lights from midnight until dawn during migration. Volunteers also help rescue birds.

Win-Win

Step three: Win-Win. Birds find their way better, and the buildings save energy too. Many cities have joined.

A Closer Look

Let's take a closer look! Switch off lights. Mark windows. Keep it dark at night. Protect migrating birds.

Quick Facts

Quick facts! Most migrating songbirds travel at night. Dots or stickers on glass help birds see windows. Dark towers save energy. Spring and fall are busiest.

Think Like a Scientist

Now, think like a scientist! Make a poster asking a building to turn its lights off at night during bird migration. Draw a lit tower. Draw a dark tower. Show a bird flying safely past the dark one. Add a catchy slogan.

Outro

Lights out programs ask buildings to switch off unneeded lights at night during migration, so birds that fly at night don't get confused or hit glass. It saves energy too. Science is amazing!
