I think I've figured out the birds living in the tree in front of my car. I think their conversations go something like this:

Bird #1: Okay, Mona's on her way home from the car wash.
Bird #2: Are you thinking what I'm thinking?
Bird #1: No one take a crap until her car's in front of us.
Bird #2: I can hold it. Can you?
Bird #1: (indecipherable chirping)
