The birds of paradise (family Paradisaeidae ) represent a quintessential example of extreme phenotypic elaboration driven by sexual selection. While the plumage and display behaviors of male birds of paradise are well-documented, the precise evolutionary trajectories that allow for such divergence without catastrophic fitness costs remain a subject of debate. This paper presents a novel computational model designed to simulate the evolutionary pressure of female choice on male trait elaboration. By integrating agent-based modeling with quantitative genetic parameters, we simulate the "runaway" process proposed by Fisher and the "handicap principle" proposed by Zahavi. Our results suggest that the extravagant traits observed in Paradisebirds models are sustainable only under specific ecological conditions where predation pressure is decoupled from display environments. This study provides a framework for understanding the constraints and catalysts of extreme ornamentation in isolated ecosystems.
