Abstract
Raptor or bird of prey is a top predator in the food chain. The important role of raptor as a counterweight and indicator of ecosystem health in forest areas. Bromo Tengger Semeru National Park (TNBTS) is habitat for several types of raptor. The aim of this study to identify the raptor species which is found in RPTN Jabung and RPTN Coban Trisula TNBTS. This research was conducted in September - November 2019. Identifying raptor species and individuals was carried out using the cooperative point count method. Data analysis was performed by calculating population densities and abundance values based on encounters with raptor species. The results of identification raptor in RPTN Jabung is showed 8 types of raptors with 94 individuals and in RPTN Coban Trisula is showed 8 types of raptors with 20 individuals. The highest value of raptor population density in RPTN Jabung is Tachyspiza soloensis species with density values 43.18 individual/Ha. Species that often appear is Nisaetus bartelsi with an abundance of category 3 (often appear). The highest population density value in RPTN Coban Trisula is Ictinaetus malayensis and Spilornis cheela with density values 2.85 individual / Ha. The species that often arises is Ictinaetus malayensis with an abundance of category 2 (uncommon).
