Why do male Andean cock-of-the-rock birds gather in leks?
A To defend their territory
B To perform courtship displays
C To migrate together
Fact: During mating season, male Andean cocks-of-the-rock gather in leks—communal display arenas—where competition is fierce. They often break into pairs, facing off in ‘confrontation displays,’ bowing, flapping their wings, jumping, and even snapping their bills while grunting. As a female approaches, the energy escalates into a chaotic mix of color and sound. The flashiest performer wins her attention, but after mating, his role ends. She builds a cup-shaped mud nest on a rocky surface, lays two eggs, and raises the chicks alone.
Correct Answer: To perform courtship displays
