Birds play a variety of ecological roles as bioindicators of ecosystem health, where their reproductive success and nesting behavior are influenced by the diversity of habitat vegetation. Although some areas implement green development concepts, fragmentation due to urbanization in these areas could alter microhabitat structure and affect the presence and reproductive success of local birds. This study aims to inventory and identify the characteristics of bird nests on the Bangka Belitung University (UBB) campus as baseline data to guide management in mitigating the impacts of development on fauna sustainability. This study was in March 2020. Data collection was conducted using the transect method, with a total transect length of 9 km. The presence of bird nests was determined by visual observation. From the observations, 20 bird nests were found, 16 of which were active nests. Based on their characteristics, the nest found can be grouped into four nest types. Five types of plants were identified as used as nesting sites, including kedebik, saga, ketapang kencana, cempedak, and seru. Kedebik (Melastoma malabathricum L.) and Ketapang kencana (Terminalia mantaly H.Perrier) are the most common nest tree in our study area. The nests found are cup-shaped with a basal attachment type, typical nests of birds belong to Order Passeriformes. The nests are composed of natural materials, such as grass, ferns, dry leaves, twigs, and feathers. It is hoped that the reported findings can be used as consideration in the future development of the UBB campus
