Breeding Hyacinth Macaws in captivity can be moderately challenging. They usually lay 2-3 eggs per clutch, with an incubation period of about 28-30 days. Chicks fledge at around 3 months. In the wild, they typically nest in tall trees with natural cavities. During breeding, they are very sensitive to environmental changes, so providing a quiet, stable environment is essential. Nest boxes should be large and deep, lined with soft materials to mimic natural tree cavities.
