Avian Diversity in the Himalayas


  • Dhananjai Mohan Wildlife Institute of India, Dehradun, Uttarakhand, India




Diversity, bird species, indian himalayan region, distribution


The Indian Himalayan mountain region is globally renowned for biological
diversity. The Himalayan mountain system contributes 10% of the world
bird’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 Himalayan
region; various factors are responsible for bird’s diversity gradient seen in
this mountain chain. The present article is briefing on the bird’s species
diversity patterns in the Indian Himalayan region and is largely based on
the work carried out under Wildlife Institute of India and University of
Chicago collaborative research work titled ‘Study of bird species numbers
and densities in east and west Himalayas’ and has already been published in
many research papers.

Author Biography

Dhananjai Mohan, Wildlife Institute of India, Dehradun, Uttarakhand, India

Dhananjai Mohan received his graduation degree in Electrical Engineering
from Indian Institute of Technology (IIT), Kanpur in the year 1986. Later he
joined the 1988 batch of Indian Forest Service and was allocated to the state
of Uttar Pradesh and later on its split to the Himalayan state of Uttarakhand.
He served as manager and management planner of protected areas in the
Himalayan and terai regions of erstwhile Uttar Pradesh. He served as an
Associate Professor in the Indira Gandhi National Forest Academy, Dehradun
from 1998 to 2004 dealing with the subject of wildlife conservation and as
a Professor in the Wildlife Institute of India, Dehradun from 2006 to 2013
where he led avifaunal research and collaborated with University of Chicago
to conduct research on Himalayan bird diversity gradient. He did his Post-
Graduate Diploma in Wildlife Management in the year 1992. He was awarded
a Ph.D. degree on ‘Habitat selection of birds in New Forest, Dehradun,
India’ by the Forest Research Institute Deemed University, Dehradun. He
also served in the wildlife headquarters of Uttarakhand Forest department for
over five years. Before taking over as Director Wildlife Institute of India,
Dehradun in January 2020, he served as Principal Chief Conservator of
Forests, Planning and Financial Management and Chairman State Biodiver-
sity Board, in the state of Uttarakhand. He has written a book and contributed
a book chapter and has many publications particularly on avifauna, his pri-
mary interest. Some of these were published in topmost international journals like Nature, Nature communication, American naturalist, Biology letters and
Journal of Ornithology. Dr Mohan has been a passionate birdwatcher and
naturalist for nearly four decades and has spanned the length and breadth of
the country in pursuit of it.
Dr. Dhananjai is a fellow of Leadership for Environment and Develop-
ment (LEAD), a programme initiated by the Rockefeller foundation. He has
been a recipient of Dr Salim Ali fellowship of Ministry of Environment
and Forests, Govt. of India in 2005. He served as a consultant to TERI and
supervised a doctoral research and 10 M.Sc. dissertations in wildlife science
and forestry.
