This study investigates the impact of land‐use changes on avian diversity in an agricultural landscape ecosystem in the Usambara Mountains, northeastern Tanzania. The East Usambara Mountains have lost a significant part of their original natural forests. On its southern part, the main forest block is found in Amani Nature Forest Reserve, while the rest of the landscape is fragmented into agricultural mosaics. The study, conducted from 2020 to 2023 using point count observations, documents the avian diversity in different habitats within agricultural landscapes, considering rainy seasons' effects. A total of 4107 individual birds representing 121 species from 39 families were recorded, with notable variations in species diversity across different habitats. Agroforestry systems demonstrated higher avian diversity than forest remnants, agriculture, tea plantations and shrubland. Proximity to forest positively influenced bird diversity, with a significant proportion of true forest species highlighting the importance of intact forest ecosystems. Seasonal variations were evident, with the short rainy season exhibiting higher species richness in certain habitats. The findings of this study underscore the need for conservation strategies that prioritise forest protection and restoration while promoting sustainable agroforestry practices.
