Where Khangchendzonga - the third highest peak dominates
the horizon, within such a small size and land area of
7096 sq. kms, bio-diversity in Sikkim can undoubtedly be
one of immense interest to ecologist and
environmentalists, earth scientist and nature lovers,
botanist and biologists in equal measures. Sikkim
epitomises the pithy saying: Small is Beautiful.
There
is a great variety and numerical abundance of the
resident birdlife with an overall 550 species which
would account as much as 30% of the aggregate bird
species found in India, Nepal, Bhutan, Pakistan,
Bangladesh and Sri Lanka.
From pheasants and tragopans, thrushes and magpies, to
hawk-eagles and kingfishers, the variety and richness is
breathtaking.
Of
the 1400 species of butterfly fauna found in the Indian
Subcontinent as many as 700 species occur in Sikkim. Of
the diversified butterfly fauna, Sir Joseph Dalton
Hooker, thus said: " by far the most striking feature
consisted in the amazing quantity of superb butterflies,
large tropical sallowtails, black with scarlet or yellow
eyes on their wings. They were seen everywhere
majestically through the still hot air, or fluttering
from one scorching rock to another and especially loving
to settle on the damp sand of the river edge, where they
sat by thousands with erect wings, balancing themselves
with a rocking motion as their heavy sails inclined them
to one side or the other, resembling a crowded fleet of
yachts on a calm day. Such an entomological display
cannot be surpassed."
The forest stands are very diverse, and non-forested
areas-such as cliffs, high alpine meadows, cascading
streams and places all provide places birds to feed,
rest and raise their young. A wide variety of
residential and non-residential birds can be seen along
the trail at different elevations and in different
seasons.
About
180 big and small lakes spread over Sikkim's folds and
faults are the habitat of an umpteen number of resident
and migratory waterfowl and for Brahminy ducks
principally, they are the permanent breeding habitats.
Recent study results of about 47 species of waterfowl
ranging from Blacknecked Grebe and Large Coromorant to
Egret and Brownheaded Gull. Also found to occur are the
Herons, Lapwing, Crake, Moorhen and Snipes.
