Nepal is home to a diverse range of bird species, thanks to its varied ecosystems that span from lowland tropical forests to high-altitude alpine meadows. While the exact number of bird species in Nepal can vary slightly due to taxonomy changes and new discoveries, as of my last knowledge update in September 2021, there are approximately 900 to 1000 bird species recorded in Nepal. These species belong to various families and can be broadly categorized into different groups based on their habitat preferences and characteristics.
