What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do common nighthawks nest on city rooftops?

The Big Idea

Some birds lay their eggs on flat city rooftops! Meet the common nighthawk. It hunts insects at dusk.

Insect Hunters

Step one: Insect Hunters. Common nighthawks are birds that catch flying insects at dusk. They swoop through the evening sky.

Gravel Roofs

Step two: Gravel Roofs. They used to nest on bare ground in open areas, and flat gravel roofs are similar. A mother lays her camouflaged eggs right on the gravel.

Booming Dives

Step three: Booming Dives. You may hear the booming sound of males diving through the air in summer evenings. Nighthawks are listed as a species at risk in Canada.

A Closer Look

Let's take a closer look! They hunt at dusk. Eggs blend with gravel. Males boom in dives. They need protection.

Quick Facts

Quick facts! The booming sound comes from air rushing through their wings during a dive. Eggs blend with gravel. They eat lots of insects. At risk in Canada.

Think Like a Scientist

Now, think like a scientist! Go outside with a grown-up at dusk in summer. Listen for the nighthawk's nasal call. Look for birds swooping after insects. Draw what you think it looks like. Check a bird book to compare.

Outro

Common nighthawks nest on flat gravel rooftops because they are like the bare ground the birds once used. Mothers lay camouflaged eggs on the gravel, and males make booming dives. Science is amazing!
