there are birds of the Mimidae class that actually mimic crying babies and even cars eingine sounds. it's true! do your research folks.

omg, is that somebody crying!?
these aren't real
i head a car beep.....

P.S. This isn't a rainforest..it's definitely the midwest someplace..there are robin redbreasts in the background, along with starlings and bluejays..sounds like someone's Macaw thrown in there, too!
