Structure • Salient features of Indian avifauna • History of ornithology • Significance of birds • Birds as a ecotourism resource • Conservation issues • Monitoring birds • Birds as indicators
Total species richness Threatened species richness Endemic species richness Ormeet al. 2005
Indian Avifauna: Diversity 1303 (of 10448) species in the country (IOC, 2011) Includes ca.100 more added by Rasmussen and Anderton (2005) in the subcontinent ~ 13% of world’s avifaunal diversity 27 orders (of 40) and 110 families (of 228) 976 breeding birds South-Eastern Himalayas having 570 breeding birds in 250X250 km grid
Indian Avifauna: Endemism In India, there are only 78 species, i.e. 6% Indian subcontinent also has a markedly low number of endemic genera (12), out of which only two are confined to India (viz., Heteroglaux & Ophrysia). Major families having significant representation in Indian Sub-continent Tree-creepers (71%) Accentors (62%) Laughing Thrushes (55%) Ioras (50%) Barbets (37%) Drongos (38%)
Indian avifauna: influences Influenced by Palearctic, Ethiopian and Oriental regions Oriental region has maximum influence Indo-Malayan South China

Why such a diversity Diverse habitats Himalayan snows to tropical oceans Tropical deserts to Wet evergreen forests Trans-Himalayan wetlands to largest mangrove systems of the world 10 bio-geographic zones Rodgers and Panwar (1988)
Diverse habitats Trans Himalayas High mountains, deep valleys, flat and arid plains Wetlands (often brackish): Breeding of birds like Black-necked Crane, Great crested Grebe, Bar-headed Goose, Ruddy Shelduck Palearctic infuence Mainly in Ladakh and Lahul-spiti
Diverse habitats Himalayan region Immigration Very low speciation within (in situ) the Himalayas Speciation events attributed to vicariance between Himalayas and China/Southeast Asia (Orient)

Early history of bird study in India • Vedic times - 250 Sanskrit bird names • Brood-parasitism in the Koelmentioned in Rig Veda • Latitudinal migration of Oriental White Storks in Tamil Sangam literature • Mughal naturalist traditions - paintings, hunting, falconry and documentation • Moguls paintings and memoirs esp. of Babur and Jehangir often contained fine details on behaviour of garden birds. • 1834 AdolpheDelessert ‘Souveniers d'un Voyage dansL'Indes’ • 1752 J. Gideon Loten became Governor of Ceylon • 1781 John Latham ‘General Synopsis of Birds’ • 1790 ‘India Ornithologicus’, 1821-28 Based on Sir N B Kinnear, JBNHS 51(1): 104-110

Indian ornithology in 20th century – 2nd half • Sidney D. Ripley (1913-2001) • Smithsonian Institution, US • Bird systematist credited with the first major revision of the taxonomy of the Subcontinent’s birds since the publication of FBI series • Conducted extensive field-surveys esp. in the north-eastern India • His ‘Synopsis’ of distribution and taxonomy of Indian birds formed the basis for the 10-volume ‘Handbook’, co-authored with Salim Ali • Author of highly acclaimed monographs on waterfowl and rails & crakes
Indian ornithology in 20th century – 2nd half • Sálim Ali (1896-1987) • Arguably, the most charismatic ornithologist in the Subcontinent (‘Birdman of India’) • Long association with BNHS • Student of German ornithologist E. Stresemann; a close associate of Hugh Whistler and S.D. Ripley • Ornithological surveys of Central Provinces, Travancore & Cochin, Mysore, Hyderabad, Jodhpur, Saurashtra, Gangotri-Mansarovar, and Sikkim • Authored the 10-volume ‘Handbook’ along with S.D. Ripley; several regional field-guides • Involved with research projects including bird migration, economic ornithology, mitigation of birds, bird-hits of aircraft, & ecology of endangered birds • One of the leading figures of conservation movement in Independent India • Received Padma Vibhushan & J. Paul Getty Award
Modern Indian ornithology – Extensions & infrastructure • Institutions • Bombay Natural History Society, Mumbai • Centre for Wildlife & Ornithology, AMU, Aligarh • Salim Ali Centre for Ornithology & Natural History (SACON, Coimbatore) • Wildlife Institute of India, Dehradun • Organizations • Several regional bird clubs and organizations (Oriental Bird Club, Bird Conservation Nepal, Ceylon Bird Club & Field Ornithology Group of Sri Lanka, MNS, BSAP, etc.) • Recent initiatives to form a Federation of Indian Ornithologists (to be modelled as Indian Ornithologists Union) based in Bangalore • Programmes • Asian Mid-winter Waterbird Census (Jan 15-20, every year) • IBA (Important Bird Areas) Programme • ‘Migrant Watch’ Programme
The growth of bird study in India Based on data from Aasheesh Pittie (2001) A bibliographic index to the birds of the Indian Subcontinent. 10 fold growth every 50 years Life-history, behavioural and ecological studies are few. Most publications are about species distribution or occurrence. Already there is a space shortage for this kind of information.

Threatened birds of India |Their conservation requirements By Asad R Rahmani 2012 860 page book. Describes 15 CR, 15 Endangered, 52 Vulnerable, 66 Near threatened and 2 data deficient birds of India based on IUCN redlist 2011
Endemic Bird Area AnalysisBirdlife International 1997 A Restricted- range bird species is a land-bird which is judged to have had a breeding range of less than 50,000 km² throughout historical times ( since 1800). Extinct birds which qualify on the range size are included.
Endemic Bird Area An Endemic Bird Area ( EBA) is defined as an area which encompasses the overlapping breeding ranges of restricted range bird species, such that the complete ranges of two or more restricted-range species are entirely included within the boundary of the EBA.
- 27% (2623) birds are RR Sp. Indonesia highest no. India 14th ranked. - 218 EBA's identified Indonesia highest no with 24 India 13th ranked with 6
Indian EBA’s .Western Ghats 16 RR Sp.: 12 near threatened & 4 least concern .Andaman Islands 13 RR Sp. : 3 Vulnerable & 10 near threatened .Nicobar Island 9 RR Sp: 2 Vulnerable & 7 near threatened
Indian EBA’s (contd.) .Western Himalayas 11 RR Sp.: 1 critical, 3 Vulnerable, 3 near threatened & 4 least concern .Eastern Himalayas 22 RR Sp.: 11 Vu, 1DD, 5 nt, 5 l.c. .Assam Plains 3 RR Sp.: 3 Vu
