ELI5: Why do birds never shut up?

There's an enormous tree outside my window where the birds are making noise day and night.  It never stops.  Doesn't it take a lot of energy?  Doesn't it reveal their location to predators?

Birds are often brightly colored and noisy.  They don't avoid predators by hiding - they avoid them by simply being able to *fly away* at a moment's notice.  The noise is helpful actually, as birds warn each other if there are predators nearby.  

Those birds tryin' to get laid, man.  They squawk so females come to them.
