City Noise and Lights Affect Birds' Sleep, Songs: Study

Birds, like people, need good sleep.

Scientists found that city lights and noise bother birds' sleep, making them sing less and rest more the next day.

Birds use songs to find mates and protect their homes.

When they don't sleep well, their songs change, which might cause trouble for them.

This is a problem because many birds live in cities where there's always noise and light at night.

To help, cities could make less noise, dim lights, and create safe, quiet spaces for birds to sleep.
