Avian Diversity in the Himalayas

The Indian Himalayan mountain region is globally renowned for biologicaldiversity. The Himalayan mountain system contributes 10% of the worldbird’s species and about 8% of the world’s bird species breed in this region.However, bird species are not evenly distributed from East to West Himalayanregion; various factors are responsible for bird’s diversity gradient seen inthis mountain chain. The present article is briefing on the bird’s speciesdiversity patterns in the Indian Himalayan region and is largely based onthe work carried out under Wildlife Institute of India and University ofChicago collaborative research work titled ‘Study of bird species numbersand densities in east and west Himalayas’ and has already been published inmany research papers.
