We performed a comparative study of birds in Teknaf Wildlife Sanctuary (TWS), Inani Reserve Forest (IRF) and the Chittagong University Campus (CUC) in 2015.  A total of 249 species belonging to 50 families were recorded: 210 species from 46 families in TWS, 187 species from 45 families in IRF, and 182 species from 45 families in CUC.  Of these, 181 species (73%) were resident, 57 (23%) winter visitors, three (1.20%) summer visitors, two (0.80%) passage migrants and five (2%) vagrants.  According to their frequency of occurrence, 73 species (29.32%) were very common, 66 (26.5%) common, 62 (25%) uncommon and 48 (19%) rare. 120 species (48%) were passerines (97 in TWS, 95 in IRF and 97 in CUC) and 129 (52%) non-passerines (113 in TWS, 92 in IRF and 85 in CUC). Among the three areas, TWS had the greatest diversity in terms of total species, (210˃187˃182), residents (161˃148˃134), non-residents (49˃48˃39), forest indicator birds (47˃44˃31) and wading birds (48˃34˃24).
