Nepal is a country with one of the greatest altitude variations in the world. The lowest altitude is about 60 meters from sea level whereas the highest is the summit of Mount Everest, 8848m. The great variation of altitude has resulted in great climatic and biological diversity. We can find climatic conditions from very cold to tropical hot in a width of just 160 km. Nepal haws a wide range of flora and fauna and many species are the endemic from here. This is one of the best places for birding in the whole world. The whopping 900 species (10% of the world’s total bird’s species, more than Europe and North America combined) makes Nepal a paradise for birding. The concentration of birds is high in spite of the small territory because there are different kinds of dwelling places for birds here such as wetlands, lakes, tropical and subtropical forests, coniferous and Himalayan valleys.
