Within their natural range, the Blue-headed Mini-Macaws or Coulon’s Mini-Macaws (Primolius couloni) usually breed from October to April.
These parrots usually make their nests in the cavities of trees or bamboos.
A clutch consists of 2 – 4 eggs, which are incubated for about a month. Both parents protect and feed the nestlings. The chicks fledge when they are about 3 months old, but they will remain with their parents for some time after fledging.
These macaws are rare and, therefore, captive breeding has been seldom achieved. The blue-headed macaw is easily tamed and hardy, once properly acclimatized. They enjoy chewing fresh branches, which should be made available to them regularly.
They require a spacious aviary to allow them space to exercise for good health and to accommodate the nesting box, chewing and perching branches, and the usual food and water dishes. A good dimension for an aviary might be 9 x 4.5 x 6 ft (3 x 1.5 x 2 m) with an adjoining indoor section – heated if temperatures go below 64°F (18°C). A diagonal nest box is preferred: 9 x 16 x 12 ins (22 x 40 x 30 cm), with an entrance diameter of 3 inches (8 cm).
A clutch usually consists of 3 to 4 eggs that are incubated for 26 days. The young fledge 12 weeks after hatching. Up to 2 breedings a year are possible.
