The present study is the first preliminary checklist of Birds from National Botanical Research Institute (NBRI), Lucknow, Uttar Pradesh. It is a botanical garden located at 26.8563° N and 80.9499° E in Lucknow. The survey was carried out from January 2023 to April 2023. A total number of 45 bird species were observed and photographed. The identification was done using field guides, relevant literature, and online bird data depositories. Avifaunal Diversity is one of the most important ecological indicators to evaluate the status of habitats. Birds are the crucial animal group of an ecosystem which maintains a trophic level. Therefore, detail study on avifauna and their ecology is important to protect them. They are one of the biological control tools to control pests in gardens, on farms, and other places. They abet in the pollination of plants. Birds are also good seed dispersal. Surveys were carried out seasonally and observations were done using Line Transect Method with the aid of 10x50 binoculars and Camera(Canon EOS 100D, Super Zoom Lens 55X).NBRI Avifaunal Assessment which comprised of45 bird species was from 15 orders and 26 families. The order Passeriformes had maximum 21 bird species; Insectivorous birds (35%) were the most numerous, followed by Carnivores species (21%), Omnivores species (19%), Frugivores (15%), Granivores (10%).
