This research investigates on the habitat quality, population dynamics, and behavioral ecology of the Cenderawasih bird in Papua, Indonesia. The study uses stratified random sampling, acoustic monitoring, and behavioral observations to demonstrate considerable differences in bird abundance and species richness across different habitat types. Primary forests had the best habitat quality, with dense canopy cover, towering trees, and abundant fruit-bearing flora, which supported the highest bird numbers and species diversity. Secondary and disturbed regions, by comparison, had much lower bird numbers and biodiversity. Regression and correlation studies revealed that canopy cover and tree height are important predictors of bird density, emphasizing the relevance of these habitat factors. Behavioral investigations indicated regular courting displays, eating, and nesting activity in primary woods, indicating ideal circumstances for the Cenderawasih bird's ecological requirements. The findings underscore the importance of primary forests in preserving bird biodiversity, as well as the necessity for focused conservation activities such as habitat protection, restoration, and community participation. This research provides a solid scientific foundation for creating effective conservation policies to preserve the long-term survival of the Cenderawasih bird in Papua.
