The diversity of bird species in Ternate island

A study has been conducted with the purpose of knowing the type diversity of birds in various habitats (research sites) and to identify which species of bird are dominant in a variety of selected habitat. This research lasted for 3 months from April to June 2015 located in the cluster are of Ternate Island. The sampling and collecting data are taken from five habitat types in the study site: Settlement, Plantation, River Basin, Secondary Forest and Primary Forest. 3 observation points taken randomly are made in each type of habitat, but the determination of the observation point is adjusted to the easily accessible field condition to make the observation so that the total number of points obtained 15 observation points. The data collection of the diversity of bird species is done using TSCs (Time Species Counts) method which is the calculation of bird species by time and free exploration. In this method, the data is recorded in six columns with a time interval of ten minutes with a one-hour count of each survey. To calculate the diversity of bird species by using Shannon-Wiener Diversity Index according to Bibby et al, (2000) with the formula H’ = - Σ Pi. ln.Pi where: H’: Shannon- Wiener Diversity Index; In: Basic logarithm; Pi: ni/N; ni: i number of species; N: Number of all species. From the research result, it is found that 64 bird species, among the bird species that have been found, are relative of paruh bengkok bird such as Kakatua putih (Cacatua alba), Kasturi Ternate (Lorius garrulus), Nuri kalung ungu (Eos squamata), Betet-kelapa paruh-besar (Tanygnathus megalorynchos) and Perkici dagu-merah (Charmosyna placentis). In which these birds occupy the height from the sea reaching to the 1000 m above sea level above the sea level and some are kept by the community during the research such as Kakatua putih (Cacatua alba), Kasturi Ternate (Lorius garrulus) and Nuri kalung ungu (Eos squamata).
