Species Described That Were Not Valid Species

A number of species described during this period have turned out not to be valid species. There are a number of reasons for this. The following is a list of these species:

  • Cox's Sandpiper, Calidris paramelanotos, in 1982, now known to be a stereotyped hybrid between males of the Pectoral Sandpiper and female Curlew Sandpipers.
  • Bulo Burti Boubou, Laniarius liberatus, from Somalia, in 1991
  • Kenyon's Shag or Amchitka Cormorant, Phalacrocorax kenyoni, in 1991, now considered to refer to small females of the Pelagic Cormorant.
  • Mascarene Shearwater, Puffinus atrodorsalis, in 1995, now considered indistinguishable from the Tropical Shearwater, Puffinus lherminieri bailloni (or P. bailloni bailloni)
  • Brigida's Woodcreeper, Hylexetastes brigidai, in 1997, now usually considered a subspecies of the Red-billed Woodcreeper pending thorough study.

Famous quotes containing the words species and/or valid:

    “Any reading not of a vicious species must be a good substitute for the amusements too apt to fill up the leisure of the labouring classes.”
    —James Madison (1751–1836)

    “Written poetry is worth reading once, and then should be destroyed. Let the dead poets make way for others. Then we might even come to see that it is our veneration for what has already been created, however beautiful and valid it may be, that petrifies us.”
    —Antonin Artaud (1896–1948)
