The objective of this research was to analyse the diversity of wild birds in Mt. Tumpa Forest Park. The park is a conservation area in a protected forest in Manado, North Sulawesi. For this purpose, randomly selected line transects were established across four types of habitat: primary and secondary rain forests, shrub, meadow, and agricultural land. A total of 403 individuals of birds consisting of 33 species from 19 families were recorded. Among these, Passer montanus (Passeridae) and Scissirostrum dubium (Sturnidae) were the most abundant with the number of 100 individuals/km2, respectively. The value of Shannon-Wiener index 2.94 indicates that the diversity, the spread of number of individuals in each species, and community stability are moderate. The value of evenness below one (0.713) indicates that there is a dominant species in the community, and the distribution of the species is uneven. The species richness (Margalef index) was high based on its value 5.334. Deforestation and hunting of wild birds in this area are urgently needed to be controlled for the sake of better bird conservation, especially those of endemic and endangered species. © 2017 author (s).
