Birdie trash talk

These little birds hang out by our side door all day. There's a third one (maybe more) sitting inside the tray at the inside top of the eave. They chirp all day, talking to these birds next door:

Again there are three or four of them at this house. They chirp back and forth, fluttering from roof to railing to bricks. They never fly from one house to the other.

This morning as I watched and listened to them, I could almost hear them trash-talking each other. "Yeah? You think you're sooo great because your house has bricks? Well, we've got a dog with a bell. Boo-yah!"
