Bird Zzzzzongs

What do birds and people have in common? Dreaming, scientists say. People often dream of events that happened during the day. Scientists say birds dream about singing.

Scientists attached a special device to the head of a bird called a zebra finch. Scientists watched how the bird's brain acted while it was singing. Then they watched how the bird's brain behaved while it slept. The bird's brain acted the same way!

Scientists say zebra finches probably dream about singing in order to remember their songs.
