Reproduction & Growth
Rheas are polygamous with males courting between two and 12 females. After mating, he builds a nest, in which each female lays her eggs. The male incubates from 10-60 eggs, each weighing about two pounds. Incubation lasts about 40 days, the chicks hatch within 36 hours of each other. The females, meanwhile, may move on and mate with other males.
While caring for the young, the males will charge at anyone - including humans and female rheas who approaches the chicks. Males defend their nest by lowering theirheads and hissing, often grasping each other's beaks. Males raise chicks independently of a female. Rheas are sexually mature at two years.
