The Ivory-billed Woodpecker... has company:
In their annual year-end review BirdLife International notes that several bird species were re-discovered in 2005 following decades of of absence:
"A number of birds were seen after decades without confirmed sightings, including the distinctive endemic Peruvian race of the endangered Southern Helmeted Curassow Crax unicornis koepckeae, not recorded since 1969. In Angola, the Orange-breasted Bush-shrike Laniarius brauni and White-headed Robin-chat Cossypha heinrichi (last seen in 1957), and the Black-tailed Cisticola Cisticola melanurus (last seen in 1972), were refound."
An interesting MSNBC report on the story (entitled, "Extinct Birds Are Making a Comeback") starts off as follows:
"Scientists beware: Don't count your extinct bird species, because one of them may hatch. Several supposedly extinct birds have recently been "rediscovered," raising hopes that others not seen for ages may still be taking to the skies. "The real message of rediscoveries is that we didn't look hard enough in the first place," said Nigel Collar of the British-based conservation group BirdLife International. "We think we've explored the planet when we haven't. We have this assumption that we know it all, but we don't."
....Amen
