Red-fronted macaws form monogamous pair-bonds that are maintained year-round. Even outside of the breeding season, copulation and preening occur exclusively between pairs presumably to maintain their bond. Pairs also exhibit caressing behaviors defined by nibbling face feathers or grasping beaks. Since both the male and female are similar in color and size, sexual dimorphism is not the basis of mate selection.
Mating System: monogamous
Red-fronted macaws breed once a year between October and March. They nest in cavities on angled cliff sides of narrow, rocky gorges. Nests are comprised mainly of sandstone. They lay 1 to 3 eggs per season and incubation is around 26 days.
Breeding interval: Red-fronted Macaws breed once yearly.
Breeding season: Red-fronted Macaws breed from October to March.
Range eggs per season: 1 to 3.
Average time to hatching: 26 days.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous
Observations have shown that both parents tend the nest, but time spent in the nest varies in each pair. After young hatch, parents spend most of their time in the nest. Post-fledging, juveniles join a flock with their parents. Many social activities occur within the flock, but the majority of interactions occur within members of the same 'family' (parent-parent, parent-juvenile, juvenile-juvenile).
Parental Investment: altricial ; male parental care ; female parental care ; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Male, Female, Protecting: Male, Female); pre-weaning/fledging (Provisioning: Male, Female, Protecting: Male, Female); pre-independence (Provisioning, Protecting); post-independence association with parents
