Cousin of the Trumpeter, the Harper swan has a much harder time getting into funk bands.

I love Wiki entries that leave some of a mystery intact.  I don’t consider it so much a lack of solid scientific information being included in the entry (…okay, maybe I do…) but a deference to a more poetic interpretation.  This would certainly be appropriate for the entry for “swan song”, after the reading of which I’m not only left asking, “so do they sing when the die or don’t they?” but also, “ohmygod, do they really pull out a harp and accompany their own dying aria with a harp solo plucked out with their own swan lips??”  There’s a “put it on my bill” joke in there somewhere…
