The last report on bird identification on the UNS was in 2015 with the results of 50 bird species, while the development and reforestation processes proceeded rapidly after that. Avifauna is a collection of birds that inhabit a certain location, the wealth and abundance of which is the basis for further studies. Birds are one of the animals that are closely related to human life and the process of changing habitats. Birds can be used as indicators of the condition of an environment. In addition, as an ecological function, birds can be seed dispersal agents and natural pollinators. Birds are also used by humans as pets and food, and play a role in various cultures of society. This study aims to identify birds based on dominant species, cosmopolitanism, endemicity, and then make a comparison with the results of previous studies to see the shift in species that inhabit the UNS. Collecting data using Line transect and point count methods for identification, followed by comparing newly obtained data with previous study. The results showed that 55 species were found, with the dynamics of adding new bird species and disappearing birds from old data. Birds are identified in various statuses with habitat adjustments that are currently developing.
