Abstract
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).
Highlights
Though comparative study is very important to justify the habitat quality of birds, but in Bangladesh only one comparative study on the birds of five protected areas (Lawachara, Satchori, Rema-Kalenga, Chunati and Teknaf) was done by Khan & Aziz (2014 )
Teknaf Wildlife Sanctuary (TWS) is a peninsular landmass protected as a sanctuary since 2010 by an amendment under the provision of Bangladesh Wildlife (Preservation) (Amendment) Act, 1974, it was previously classed as a Game Reserve
Most of the Uncommon birds were recorded from TWS (51 of 62 species), with 42 in Inani Reserve Forest (IRF) and 32 in Chittagong University Campus (CUC)
Summary
Diversity of avifauna is one of the most important ecological indicators for evaluating the quality of habitats (Johnston & Odum 1956; Morrison 1986; Welsh 1987; Koskimies 1989; Temple & Weins 1989; Browder et al 2002), since flying birds react rapidly to habitat changes (Hilden 1965; Morrison 1986; Fuller et al 1995; Louette et al 1995). Teknaf Wildlife Sanctuary, Inani Reserve Forest and Chittagong University Campus are quite different habitats for birds. 1,3) is located in Ukhiya subdistrict of Cox’s Bazar (21009’–21017’N & 92002’–92011’E) is surrounded by Himchari National Park in the north, TWS in the south, a suburban area in the east and the Bay of Bengal in the west.
