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:
“An unjust law is itself a species of violence. Arrest for its breach is more so.”
—Mohandas K. Gandhi (1869–1948)
“It is not enough that France should be regarded as a country which enjoys the remains of a freedom acquired long ago. If she is still to count in the world—and if she does not intend to, she may as well perish—she must be seen by her own citizens and by all men as an ever-flowing source of liberty. There must not be a single genuine lover of freedom in the whole world who can have a valid reason for hating France.”
—Simone Weil (1909–1943)
