Pulau Rambut is a small island in Jakarta Bay that has been used as a breeding and roosting habitat for various waterbird species. The study aimed to estimate waterbird’s abundance, comparing waterbirds species and abundance data with previous studies in 1990 and 2001, and mapping the distribution of nesting trees. The study was conducted in January-February 2020. Birds were counted using the census method, while the coordinates of nesting trees were taken to map their distribution. There were 13 species of waterbirds (5 egret species, 2 day-heron species, 2 Cormorant species, 1 night-heron species, 1 darter species, 1 stork species, 1 Ibis species). Two species, the Black-headed Ibis and the Little pied cormorant were not found anymore compared to previous studies. The abundance of waterbirds was 4,950 individuals dominated by cormorant species (32%), egret species (28%), and Black-crowned night heron (23%). The number of waterbirds decreased sharply compared to previous studies. Nesting trees were distributed mostly in the east of the island, consisted of 3 sub-colony.
Aketajawe Lolobata National Park has a variety of habitat types and diverse bird species. North Maluku is one of the EBA areas (Endemic Bird Area) because it has many endemic bird species. This research aims to describe the type of habitat, identify the species of Psittacidae bird, and utilize vegetation in bird habitat, especially in the Lolobata block area. The research was carried out on August 20-28, 2018. The bird species calculation is carried out by the species list method MacKinnon table and the point count method. There were nine types of Psittacidae found at Tukur -Tukur site and Beringin Lamo site. The species of bird that dominates is Chattering lory (Lorius garrulous). Species nondominant is White cockatoo (Cacatua alba) and Violet-necked lory (Eos squamata). The habitat in both observed locations showed a variety of habitat types, namely lowland forests and riparian. Human activities around the habitat have a considerable influence on the distribution and population size of existing species groups. Based on the Minister of Environment and Forestry Regulation No. 20 of 2018, all bird species are protected.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
