The Dawn Chorus: Level 1 Reading Comprehension Questions

Before the sun is fully up, many birds begin to sing. If you wake early, you can hear them: one call, then another, then many at once. People call this the dawn chorus. But why do birds sing so much at dawn?

In the early morning, the air is often still and cool. Sound travels farther when the air is calm, so a bird's song can reach much farther than it would at noon. It is also too dark to hunt for food, so the birds use the time to call instead. A male bird sings to say two things: this is my space, and I am strong and healthy. Females listen and choose.

By the time the sun is high, the singing slows down. The birds go quiet and get to work finding food.
