Dwindling status of rarest bird Jerdon‟s courser (Rhinoptilus bitorquatus) of Andhra Pradesh and its conservation. In: New Horizons in Biotechnology. (Eds. Viswanath B and Indravathi G) Paramount Publishing House, India, pp. 308-311. Jerdon’s Courser (Rhinoptilus bitorquatus) is a nocturnal cursorial bird found only in the State of Andhra Pradesh, India. It is one of the world’s rarest bird species and is classified as Critically Endangered (CR) by the International Union for Conservation of Nature (IUCN). The species was believed to be extinct until it was rediscovered in 1986 near Reddipalli village, Cuddapah District of Andhra Pradesh, India. The site where it was rediscovered was designated as the Sri Lankamaleswara Wildlife Sanctuary. Since 2000, research on the Jerdon’s Courser and its habitat has been conducted by Bombay Natural History Society (BNHS) along with Royal Society for the Protection of Birds (RSPB) and the Universities of Reading and Cambridge, supported by the Darwin Initiative and the Andhra Pradesh Forest Department (APFD). There has been considerable progress in developing the standard survey techniques to detect their presence and describe the broad habitat requirements. However, there is a clear need for more research to procure baseline information on the species mainly through radio telemetry studies that is vital to its survival. In addition, the species is under great pressure from unsustainable development and management practices. This combination of a lack of information on the Jerdon’s Courser, coupled with increasing pressure on its habitat, has prompted stakeholders to devise a Species Recovery Plan (SRP). The main purpose of the SRP is to secure the long-term survival of the Jerdon’s Courser. The SRP advocates a multi-pronged approach that includes elements of research, monitoring, advocacy, conservation education, habitat management & training and funding. It clearly outlines responsibilities and timeframes to facilitate regular monitoring and evaluation. This paper focuses on the participation of inputs from a wide range of stakeholders including the government, NGOs, national and international scientists and civil society. It is therefore a very inclusive and realistic document. This SRP will serve as a reference for conservation managers, policy-makers, researchers, decision-makers and form the basis of future conservation actions.

It belongs to the family Glareolidae and later on by work of Baker (2); Jerdon‟s Courser. Rhinoptilus further classified into Subfamily Cursoriinae (7). bitorquatus is a nocturnal cursorial bird and one of the world‟s rarest birds found only in Andhra Pradesh, India. Jerdon‟s Courser was believed to be extinct because none was recorded after 1900 until the species was rediscovered in 1986 near Reddipalli village, Cuddapah District of Andhra Pradesh, India (3). The site where it was rediscovered was designated as the Sri Lankamaleswara Wildlife Sanctuary. Indian Courser has been described as one of the attractive birds of India. The species has been also mentioned in the cultural notes because of its behavior (4). Pande et al., (2003) has given description of behavior of the species as if the species is pursued it runs, stops and surveys. Mostly it is found in arid and semiarid areas (5). This species mostly found in India, Pakistan, Bangladesh, Nepal and Sri Lanka. It is one of the world‟s rarest bird species and is classified as Critically Endangered (CR) by the International Union for Conservation of Nature (6). This poorly known species qualifies as Critically Endangered as a result of its single, small, declining population, which is threatened by the exploitation of scrub- The subfamily Cursoriinae consists of birds of two distinct forest, livestock grazing, disturbance and quarrying. types: genus Pluvianus and true coursers. Eight species of true coursers are present around the world in three genera: genus 308 New Horizons in Biotechnology Cursorius, genus Smutsornis and genus Rhinoptilus. In India, (mainly Acacia, Ziziphus and Carissa) and non-thorny scrub two species of Cursorius courser occur, the Cream-coloured (mainly Cassia, Hardwickia, Dalbergia, Butea and courser Cursorius cursor and Indian Courser C. Anogeissus) jungle . This scrub was generally 2–4 m tall with coromandelicus; and a single species of Rhinoptilus courser, Hardwickia around and above 5 m tall .
