Birds<br />

The Isl<strong>and</strong>s are comparatively rich in avifauna. According to Abdulali (1964),<br />

avifauna affinities <strong>of</strong> the isl<strong>and</strong>s appear to be similar to India than to Burma or Malay, except<br />

for <strong>Nicobar</strong> Pigeon <strong>and</strong> Megapode which are having Australian affinities. Some species <strong>of</strong><br />

resident birds <strong>of</strong> the isl<strong>and</strong>s display distinct morphological differences from isl<strong>and</strong> to isl<strong>and</strong><br />

in size, colour <strong>and</strong> pattern forming different subspecies during course <strong>of</strong> time due to<br />

isolation. About 242 species <strong>and</strong> subspecies including 95 endemic birds have been reported<br />

by Tikader <strong>and</strong> Das (1985). Sankaran <strong>and</strong> Vijayan (1993) recorded 270 birds <strong>of</strong> which 105<br />

species <strong>and</strong> subspecies are endemic, many <strong>of</strong> them are highly restricted in range. The high<br />

proportion <strong>of</strong> endemics, however, is due to presence <strong>of</strong> large number <strong>of</strong> endemic<br />

subspecies. Of the 105 endemic species <strong>and</strong> subspecies, only 14 full species <strong>and</strong> the rest <strong>of</strong><br />

the 82 birds are (Sankaran, 1995) subspecies <strong>of</strong> species found on neighboring mainl<strong>and</strong>s.<br />

The figures <strong>of</strong> species, subspecies <strong>and</strong> endemics to the isl<strong>and</strong>s are varying due to taxonomic<br />

uncertainty <strong>of</strong> some species <strong>and</strong> subspecies. The Dept. <strong>of</strong> Environment <strong>and</strong> Forests, A <strong>and</strong> N<br />

Administration listed a total 268 species <strong>and</strong> subspecies <strong>of</strong> birds from A <strong>and</strong> N Isl<strong>and</strong>s <strong>of</strong><br />

which 98 species <strong>and</strong> subspecies are endemics. Dasgupta et al. (2002) listed about 50 full<br />

endemic species from India, <strong>of</strong> which 15 are from A <strong>and</strong> N Isl<strong>and</strong>s (7 sp. <strong>Andaman</strong> Group, 5<br />

species <strong>Nicobar</strong> Group <strong>and</strong> 3 species common in both A <strong>and</strong> N Id.) but no mention about the<br />
