The first part of this survey focused on offshore The earliest reports on the avifauna of Andaman Islands are waters and islands in the Arabian Sea and was completed by Blyth (1845, 1846a, 1846b, 1863, 1866—the last with during October–November 2005 (Pande 2005).

Here we present Nicobar Islands from various other collections were recorded a report of the third and final part of the survey. by naturalists like Mouat (1863), Pelzeln, (1865, first report of Nicobar avifauna in Tikedar, 1984), Walden (1866, 1873), Study area Beavan (1867), Tytler (1867), Ball (1870, 1872), Hume (1874, The Andaman and Nicobar, or, Bay Islands, in the Bay of 1875, 1876), St. John (1898), Butler (1899, 1900), Cory (1902), Bengal (06º45’N–13º30’N 92º20’E–93º56’E), extend over 800 Richmond (1902) and Osmaston (1905,1906a, 1906b, 1908). km from north to south and have an approximate landmass Some prominent avifaunal collectors were Barbe, Capt.

Later studies on bio- ecology and migratory and other birds of the Bay Islands were by Wickham (1910), Whitehead (1912), Kloss (1927), Ferrar (1932), Bayley-de-Castro (1933), Stapylton (1933), Osmaston (1933) and, Vaurie (1959, 1965). There was a lull after World War II and immediately after Indian Independence, due to administrative problems, after which bird studies of the Bay Islands were resumed with reports by Abdulali (1964, 1965, 1967a, 1967b, 1971, 1976, 1981a, 1981b), Das (1971), Mukherjee & Dasgupta (1975), Dasgupta (1976), Mukherjee (1981), Saha & Dasgupta (1980), Tikader (1984), Whitaker (1985), Davidar et al.

These are just a few of the major references from a larger bibliography on the avifauna of the Bay Islands (see pp. 181–197, this issue). In 2005, ELA Foundation (Pune) and the Fig. 1.

The Bay Islands comprise 324 large and small islands endemic to the Bay Islands (Tikedar 1984). There are seven and are broadly divisible into three groups: national parks and 91 sanctuaries in the Andaman group and five national parks and one biosphere reserve in 1. Andaman group: comprising the islands of North Nicobars, comprising more than 16% of the total area of the Andaman, Middle Andaman, South Andaman, Andaman and Nicobar Islands (Pande et al. 1991; Kumar et Baratang, Rutland and other smaller islands and, al. 2005).

Avian taxonomy is currently are: giant evergreen (multi-tier climatic climax along river undergoing change and remains a bit unclear with a few banks), Andaman tropical evergreen, southern hill top endemic Bay Island sub-species being upgraded to species tropical evergreen, Andaman semi-evergreen, Andaman level by Rasmussen & Anderton (2005). moist deciduous and, littoral and mangrove forests. Some vegetation cover also comprises of cane and bamboo brakes (Tikedar 1984; Anon., undated). The faunal elements of these islands bear both Indo- Malayan and Indo-Chinese affinities due to the geographic proximity of those landmasses (Smith 1931; Stoliczka 1870 quoted in Tikedar 1984). The absence of large mammals and presence of endemic fauna and flora is an interesting aspect of their composition (Tikedar 1984) since rare species are under greater threat than others and conservation biology largely focuses on their conservation (Gatson 1994). 28 endemic bird species (excluding races) are reported from Andaman and Nicobar groups of which 20 are endemic to the Andaman and eight to the Nicobar group (Jathar & Rahamani 2007). 103–105 taxa (37–38.2%) out of 268–270 avian species and races recorded from these islands are endemic—illustrating a high degree of endemism (Sankaran Niranjan Sant & Vijayan, 1993; Vijayan et al.
