Conspiracy of ravens, that is!
Birkiland sells elegant Raven clothes hangers by Ingibjorg Hanna Bjarnadottir. These are laser-cut plywood, come in with steel chains from which they can be suspended from the ceiling (good for the currently-popular clothing-as-wall-art application) or with traditional hook or two clips for hanging a skirt in the closet. They also, mysteriously, come in white. The clever concept would of course work equally well with a convocation of eagles, a parliament of owls, a murder of crows or a charm of magpies, though the bold, graphic effect perhaps works best with a monochromatic birds. Also, I suspect that a a pitying of doves would be more elegant than a flamboyance of flamingos and more practical than a trembling of finches. I have also seen wire hangers bent so that they are shaped like bird silhouettes, but sadly, I do not recall where I saw this.

Terms of venery are readily found with varying degrees of veracity on the internet. The book An Exaltation of Larks by James Lipton is delightful.
