 The
Northeast is endowed with very rich heritage of flora and
fauna. The region is home to a large variety of birds. In
addition, many migratory birds visit the region every year
during the winter months.
The total number of bird species known
to science as inhabiting the earth to-day has been estimated
as about 8600. If subspecies or geographical races are taken
into account, the figure would rise to nearly 30,000. It is
estimated that the Indian subcontinent is the home for about
2100 forms of which over 300 are winter visitors, chiefly
from the Palaearctic Region to the north. A large proportion
of these birds can be seen in the Dooars,
Sikkim and Darjeeling
region.
 The
Indian subcontinent is divided in five geographical primary
subdivisions in order to understand the bird habitat better.
Interestingly, this region is the confluence of three of the
five subdivisions, namely the Indo-Gangetic Plain, The Himalayas
and Assam. This has resulted in sighting of a large variety
of avifauna in the region.
The birds that are commonly visible in the
area include water birds like Pelican, Cormorant, Heron, Egret,
Stark, Ibis, different types of Ducks and Goose. The other
common bird species include different types of Myna, Stint,
Snipe, River Turn, Pigeon, Swift, Hoopoe, Woodpecker, Swallow,
Martin, Shrike and many other bird varieties. |
