Jerdon's Courser

Jerdon's Courser (Rhinoptilus bitorquatus) is a nocturnal, ground-dwelling bird of the family Glareolidae, endemic to a narrow belt of undisturbed scrub jungle in the Eastern Ghats of Andhra Pradesh, India. The species was first described by the British surgeon-naturalist Thomas C. Jerdon in 1848 from specimens collected in the hilly tracts near the Penna and Godavari river valleys. After a handful of nineteenth-century sightings—the last credible record dating to 1900 near Anantapur—the bird vanished from the scientific record for more than eight decades and was widely presumed extinct. It is protected under Schedule I of the Wildlife (Protection) Act, 1972, which confers the highest level of legal protection available under Indian domestic law, and it is listed as Critically Endangered on the IUCN Red List and on Appendix I of the Convention on Migratory Species (CMS).

The bird's modern conservation story begins with its dramatic rediscovery in January 1986 by the ornithologist Bharat Bhushan of the Bombay Natural History Society (BNHS), who located it in the Lankamalleswara scrub forest near Cuddapah (Kadapa). The rediscovery relied on traditional trapping knowledge: local Yanadi trappers, who knew the bird as a quarry caught in horsehair noose traps, helped confirm a living population. This event transformed Jerdon's Courser into a flagship case study for the rediscovery of a "Lazarus species" and prompted the creation of dedicated protected habitat. In 1988 the Government of Andhra Pradesh notified the Sri Lankamalleswara Wildlife Sanctuary, covering roughly 464 square kilometres, specifically to safeguard the courser's last known range.

Surveying the species presents acute methodological challenges because it is strictly nocturnal, secretive, and occurs at very low densities. Conventional daylight transect counts fail entirely. Researchers developed a tracking-strip method, smoothing patches of fine soil to record the bird's distinctive footprints, and later deployed camera traps and call-playback techniques. The BNHS, in partnership with the Royal Society for the Protection of Birds (RSPB) and BirdLife International, refined a footprint-identification protocol that distinguished the courser's tracks from those of sympatric species. The last widely accepted photographic confirmation came from camera traps in 2008–2009; subsequent surveys have failed to produce confirmed records, raising fears that the population has declined further or that detection methods remain inadequate.

The principal contemporary threat episode involved the proposed Telugu Ganga Canal project and associated irrigation infrastructure, whose alignment threatened to cut through known courser habitat in the Lankamalleswara–Veligonda tract. Conservation litigation and BNHS advocacy in the mid-2000s sought rerouting of the canal to spare core habitat, making the species a landmark example of the tension between infrastructure development and endemic-species protection in India. Quarrying, illegal grazing, conversion of scrub to agriculture and orchards, firewood collection, and the spread of invasive woody growth that alters the open-undergrowth structure the bird requires have all degraded its habitat across the Kadapa district landscape.

Jerdon's Courser must be distinguished from the broader family of coursers and pratincoles to which it belongs. Unlike the diurnal Indian Courser (Cursorius coromandelicus), a common open-country bird, Jerdon's Courser is nocturnal and habitat-restricted, which explains both its rarity and its survey difficulty. It is also frequently confused in examination contexts with the Great Indian Bustard (Ardeotis nigriceps), another Critically Endangered Indian bird associated with arid scrub and grassland; the two are unrelated and the bustard's conservation centres on Rajasthan's Desert National Park and Maharashtra rather than the Eastern Ghats. The courser is likewise distinct from genuinely extinct Indian taxa such as the Pink-headed Duck, with which it shares the rhetorical category of "lost" species.

A persistent controversy concerns whether the species still survives at all. The absence of confirmed sightings since approximately 2009, combined with continuing habitat loss, has prompted some observers to fear functional extinction, while conservation bodies maintain that the bird's cryptic nocturnal habits make absence of evidence inconclusive. BirdLife International continues to classify it as Critically Endangered rather than Extinct, and periodic survey efforts using improved camera-trap arrays and habitat-suitability modelling are ongoing. The episode also fed into broader Indian policy debates on environmental clearance procedures, the strength of Schedule I protections in practice, and the obligations India carries as a CMS Appendix I party to act against deliberate taking and habitat destruction of listed migratory species.

For the working practitioner—particularly the UPSC General Studies Paper III aspirant, environmental desk officer, or conservation policy analyst—Jerdon's Courser functions as a compact case study touching multiple syllabus themes: endemism, the legal architecture of the Wildlife (Protection) Act, the role of the BNHS and international partners, and the development-versus-conservation dilemma embodied by the Telugu Ganga Canal. It illustrates how a single narrowly distributed species can shape sanctuary notification, infrastructure routing, and litigation, and why nocturnal, low-density taxa demand survey methods unlike those used for charismatic megafauna. The species remains a recurring examination reference precisely because its story integrates legal, scientific, and policy dimensions in one geographically concentrated example.
