Back when I was a kid, I thought the word "Bimbo" was really funny (it was because of the movie "Student Body," an "Airplane!"-style riff on teen slasher flicks). I thought it meant something akin to "dumb prostitute." So these Bimbo birds were named... and for some reason, the sound they make is "Ed-Na." My friends Senen, Joanne and Stella are probably the only ones who were aware of this stupid fact.
