Abstract

Birds of prey are one of environmental changes indicators because of their position as top predator. Many of them are migratory species that migrate from northern hemisphere to southern hemisphere, and use Rupat Island (in Riau Province) as stopover habitat. One of them is Oriental Honey Buzzard (Pernis ptilorhynchus) whose satellite tracking information (from 2006-2009) are available. This study aimed at identifying distribution characteristics of stopover habitats of Oriental Honey-buzzard in Rupat Island based on satellite tracking data using geographic information system (GIS). Several environmental variables (i.e. slope, elevation, land cover) were processed into distance to the nearest map and analyzed using logistic regression analysis. The result showed that distribution of stopover habitats covered 1 276.67 km2 (87%) of totally Rupat Island (1 461.95 km2). This distribution was mostly influenced by food availability and thermal wind. Identification of these habitat characteristics provides a baseline data for managing their stopover habitats and ecologically-based development of Rupat Island. Keywords: Logistic Regretion, Pernis ptilorhynchus, Rupat Island, Sattelite-tracking, Stopover habitat characteristic

Abstract

Mudflat in Bagan Percut plays important role for many activities of waterbirds, i.e. feeding ground, shelter and many activities social. The aim of this research was to know waterbirds diversity. This research was found 33 species (5 families) of waterbirds that use mudflat in Bagan Percut. The highest number of species (26 species) was found in October. The highest diversity (H’ = 2.59) was found in February and lowest (H’ = 1.50) in March. The value of evenness (Shannon index) was higher (0.84) in February and lowest (0.60) in March and October. Charadrius leschenaultia, C. mongolus were dominant species. This identification showed that two species Mycteria cinerea and Leptoptilos javanicus were International protected species according to Vulnerable and two species Numenius arquata and Limnodromus semipalmatus Near Threatened IUCN. Fifth teen species of them were protected in Indonesia.  Keyword: bird, bird diversity, Bagan Percut, aquatic birds, waterbirds

Abstract

The study of birds using mist nets in Indonesia is still small, but this method is good enough to see how the structure of a type of bird. A study of Eurasian Sparrow (Passer montanus) in IPB Darmaga Campus expected to provide information updates on community structure and see this type of variation in body weight in the different seasons. The study was conducted at the end of the rainy season and the beginning of the rainy season in 2012 with the installation of a total of 4514 net hours. During the study 125 individuals caught Eurasian Sparrow (71 individual at the beginning of the rainy season, 56 individuals at the end of the rainy season) and 12 individuals of which the individual retrap. No difference of body weight between the beginning of the rainy season and the end of the rainy season, but there are daily variations in body weight at the end of the rainy season between morning, afternoon and evening (df = 2 , Fvalue = 5.06 , P < 0.01). Individuals in different age classes juvenile are very real in the second season (χ2 = 7.80 ,df = 1 , P < 0.01). In the adult age class, the number of individuals in the second season was not significantly different (χ2 = 0.62 , df = 1 , P > 0.05). Keyword: body weight, structure of age, beginning of the rainy season, end of the rainy season

Abstract

The Komodo dragon (Varanus komodoensis) of East Nusa Tenggara, Indonesia, is an endemic species protected by Indonesian law, mostly due to its population size and limited distribution. The natural distribution of the Komodo dragon is limited to Komodo National Park and several areas on the island of Flores and its surroundings. However, increasing population and tourism in its natural habitat might increase the conflict between the Komodo dragon and humans. To study the impact of human activities on the behavior of the Komodo dragon, we constructed an ethogram to catalog the behavioral inventories of the Komodo to enable future quantitative comparison. The Komodo dragon ethogram was obtained from observations in Loh Buaya and Loh Baru Resorts, Rinca Island, Komodo National Park. Observations were made on 10 adult males, 13 adult females, 12 juveniles, and 3 hatchlings Komodo dragons. Data were collected during July-September 2019, February-March 2020, and June-September 2020. Based on observations, observed behavior was grouped into 9 categories based on their function. Among them are sexual behavior, parental behavior, antagonistic behavior, ingestion/egestion, maintenance, movement, resting, and investigative.

Abstract

Flores hawk-eagle (Nisaetus floris) was a Critically Endangered endemic raptor species in Lesser Sunda Region, especially in East Nusa Tenggara. The lack of information and difficulties in reaching the Flores hawk-eagle's distribution area have caused difficulties in conservation efforts for this species. One of the efforts that could be made was by spatial modeling distribution of Flores hawk-eagle habitat in East Nusa Tenggara based on GIS. Using habitat distribution spatial modeling could predict the potential place where a species can live. Logistic regression was one of the methods applied in animal distribution spatial modeling, where this method was considered to have better accuracy. Through the analysis, it was found that the potential habitat for Flores hawk-eagle was 6390.48 km2 (22%), and the non-potential habitat was 22,459.59 km 2 (78%). The habitat factors that determine the distribution of the Flores hawk-eagle include slope, altitude, rice fields, plantation, forests, and shrubs. The availability of nesting trees and food for Flores Hawk-eagles may influence the distribution of existing habitats. The results of the distribution mapping of the Flores Hawk-eagle can be used as a reference in efforts to manage the habitat of the Flores hawk-eagle in East Nusa Tenggara.
