The structure of bird communities has been studied in different parts of the world butit has been less studied in the northeastern Thailand. We investigated thecomposition of bird communities using point count method in five habitats alonghuman pressure gradient from dry dipterocarp forest of Sakaerat Biosphere Reserve,agricultural landscape, rural area, urban cluster and urbanized habitat in NakhonRatchasima province, Thailand. We visited 125 point count stations during 6.00 amto 10.00 am and 4.00 pm to 6.30 pm for 20 days from November 2016 to April 2017. Altogether, we observed 9,694 individuals belonging to 131 species of 44 families.For waterbirds, we found only 230 individuals (2.4%) belonging to 6 species of 3families. Every habitats had 5 species except the dry dipterocarp forest had none.The urban cluster at Suranaree University of Technology had the highest abundance,followed by agricultural, rural and urban habitats, respectively. The most abundantbird was Egretta garzetta, followed by Vanellus indicus, Bubulcus ibis, Ardeolabacchus, Halcyon coromanda and Actitis hypoleucos, respectively. The last specieswas found only in rural habitat. All waterbirds we seen are common and have leastconcern status from IUCN Red List. Since out study areas are not close to largewater body, we find no significant difference among habitat types except the forestand among observed months at this point of our study.
