Eastern India is home to more than 850 species of birds and is considered as being the richest birding area in the country. The abrupt juxtaposition of many different biotopes or life zones – ranging from almost plains level to over 6000m, and from tropical heat to arctic cold, has given to the Eastern Himalayas a flora and fauna that for richness and variety is perhaps unequalled in the world. Sheltered in the rain-shadow lie dry practically rainless valleys adds to the ecological complexities of the jumbled habitats and make the area rich in birds, plant and insect life.
