The ivory-billed woodpecker (Campephilus principalis), long suspected to be extinct, has been rediscovered in the Big Woods region of eastern Arkansas. Visual encounters during 2004 and 2005, and analysis of a video clip from April 2004, confirm the existence of at least one male. Acoustic signatures consistent with Campephilus display drums also have been heard from the region. Extensive efforts to find birds away from the primary encounter site remain unsuccessful, but potential habitat for a thinly distributed source population is vast (over 220,000 hectares).

Greenway (1958) mentioned only 11 museums worldwide, excluding La Châtre, housing specimens of this species. "

    • "For example, the central rock-rat, Zyzomys pedunculatus, was rediscovered several times after assumed periods of extinction [61]. The greater akialoa, Hemignathus ellisianus, and the mythical ivory-billed woodpecker, Campephilus principalis, were rediscovered in 1969 [62] and 2004 [63], respectively, but neither has been observed since. Scheffers et al. [12] concluded that many of the 351 rediscovered species discussed in their study are likely to go extinct without significant conservation efforts. "

    ABSTRACT: Many scientists argue that our planet is undergoing a mass extinction event that is largely due to human influences. In this context, rediscoveries of species presumed to be extinct are encouraging and of great potential interest. During a 2003 expedition to New Caledonia, Bocourt's terrific skink, Phoboscincus bocourti, was unexpectedly rediscovered on a small islet by one of us. This skink species had been described from a single specimen collected around 1872 in New Caledonia. Since that time, however, no data on the species' biology, trophic interactions, or role in the ecosystem have been collected, making it difficult to follow the established conservation plan. In this study, we used a multidisciplinary approach involving natural history, anatomy, morphology, genetics, and stable isotopes to elucidate the ecology of Bocourt's terrific skink. Over the course of three different expeditions to the islet (total of 55 days across 2005 and 2012), we captured 4 individuals and observed another 4 individuals. The species' dentition and trophic ecology suggest that it is a top predator in its ecosystem and a major consumer of small terrestrial reptiles. Its high degree of genetic relatedness to another New Caledonian skink, which has a broad distribution, suggests that P. bocourti underwent genetic isolation at a geographical remote location, where dispersal or colonization was highly improbable. Moreover, the lack of genetic variation among the four individuals we captured may imply that a unique lineage, characterized by few inter-island exchanges, exists on the islet. Bocourt's terrific skink may be the largest terrestrial squamate predator alive in New Caledonia today. As a result, it is likely vulnerable to habitat modifications and especially the invasive rodents found on this islet. Further information is necessary to assess the conservation plans and practices in place as no concrete changes have been made since the species' rediscovery almost 10 years ago.

    • "In 2004, sightings were reported of Ivory-billed Woodpeckers (Campephilus principalis Linnaeus), a species thought to have been extinct since 1944, from the Big Woods region of eastern Arkansas, USA (Fitzpatrick et al. 2005). In response to these reports, and despite criticisms about their validity (Jackson 2006, Sibley et al. 2006), more than US$20 million were spent on a massive recovery effort that involved intensive searches, replanting of more than 20 000 ha in bottomland hardwoods, and protection of 4800 ha in the Big Woods of Arkansas (TNC 2010).

    ABSTRACT: Rare species carry a connotation of uniqueness, of being especially valuable, and of heightened extinction risk. We review the literature regarding rare species and link rarity and risk concepts to jurisdictional rarity and how to allocate conservation efforts to rare species gone long undetected. Conservation actions for rare species should be prioritized based on best available information of population trends and thresholds of minimum viable population or geographic range size. For species rare in some geopolitical jurisdictions but common elsewhere, we recommend prioritizing conservation action by assessing beyond jurisdictional boundaries to assess stewardship responsibility relative to the global distribution and at-risk status of the species in question. For making the thorny decision about when to stop managing or monitoring a long-undetected rare species, it may be optimal to continue conservation efforts for a long time, especially if the species has considerable social, economic or ecological value. Recent advances based on theories of optimality provide a replicable and transparent process upon which these decisions can be based.
