A mysterious [[pheasant]], the '''Double-banded Argus''', '''''Argusianus bipunctatus''''', is known only from the portion of a single primary [[flight feather]]. It was described in 1871 from this feather piece, found in a [[millinery]] shipment imported to [[London]]. |
|||
Its origin was hypothesized to be from [[Java (island)|Java]], [[Indonesia]] or [[Tioman Island]] of [[Malaysia]], because of the Great Argus' absence from these locations. Parkes (1992) vehemently rejected the "[[species]]" validity and argued that the Double-banded Argus almost certainly represents a [[mutant]] form of the [[Great Argus]]. The [[IUCN]], following the [[precautionary principle]], lists this [[taxon]] as [[extinct]]. |
|||
While the feather is indeed quite distinct, it represents a fairly simple divergence: The entirely asymmetrically-pattern vanes are instead near-symmetrical and both bear the darker brown shaftward area with innumerable whitish speckles. The shaft is thinner than usual and the feather would probably not have been useful for flight. |
|||
Nothing similar has come to notice ever since, and as the feather piece is not a composite of two feather halves glued together but a natural (albeit peculiar) specimen, a hoax or fake can be ruled out. Nonetheless all conjecture that has been built around the feather piece, all that can be said is that at some time around [[1870]] an argus pheasant was shot in an unknown location which bore at least one such feather. Even if this one known individual was the last remnant of a disappearing population, it is hard to believe that only a single feather would have been taken from an unusual specimen of a well-known, often-hunted, and conspicuous bird, and that this single feather would have been then transported elsewhere, to be bundled into a shipment of perfectly normal Great Argus feathers. |
|||
The feather is now housed in the [[British Natural History Museum]]. A photo of the specimen is in Fuller (2000:111). |
