Not to sure about the big feather part :)
Plume or Bloom, either way you spell it, its still the same. They are both considered on in the same. I am still new to this whole thing called cigar smoking myself.
Taken from a cigar site
Definition: Bloom - Also referred to as plume, this is a white film or spots caused by the oils in the tobacco rising to the surface of a cigar's wrapper. It is harmless, and usually indicated a strong tasting smoke.
