"nudist little bird"

Actress Drew Barrymore likens herself to a “nudist little bird” here (WARNING: Mature Content - language may be offensive to some) not because of the lark-like quality of her voice or the feathered clothing that she (doesn’t) wear, but perhaps more likely because of another trait that she apparently (along with many other individuals of the human race) shares with some species of the avian world—sexual promiscuity or, at best (and much more commonly), serial polygamy.

Oh yeah, I almost forgot, "bird" is also a British slang term for a human female (usually young and attractive), the American equivalent being "chick". Both terms may, under some circumstances, be considered offensive or sexist, depending on their usage and the perception of the person(s) to who(m) they are directed. Just so there is no misunderstanding, I am not using either term in that context here.
