Blue-headed macaw
Primolius couloni
The blue-headed macaw is one of the least-known macaw species in South America. Its distinctive blue head contrasts strikingly with the predominantly green plumage of its body, giving it a truly unmistakable appearance among the Amazon’s parrots.
Unlike more conspicuous and vocal macaws, such as the blue-and-yellow macaw or the scarlet macaw, this species is generally shy and cautious. As a result, it is notoriously difficult to observe in the wild, even within its natural range.

Blue-headed macaw facts
Primolius couloni is a medium-sized macaw, reaching approximately 41 cm in length and weighing between 207 and 294 g. Its plumage is predominantly green, while the head displays distinctive blue tones, the feature from which the species takes its common name.
The flight feathers are also blue, whereas the tail begins with muted reddish tones that gradually transition to blue at the tip. The undersides of both the wings and tail are yellow.
Its bill is black with greyish tones and is specially adapted for handling seeds and fruits of varying hardness. Like other macaws, it has zygodactyl feet, enabling it to grasp food securely and move with ease through the forest canopy.
Diet
Very little is known about the diet of this species in the wild. It feeds on fruits and seeds at both mature and developing stages, adapting its diet according to seasonal resource availability.
It has also been observed feeding on tree bark, a behaviour reported in several parrot species. In addition, blue-headed macaws gather at collpas to consume clay, which provides essential minerals that are not readily available through their regular diet.
Lifestyle
The blue-headed macaw is a diurnal species, most often seen in small groups of two to five individuals. Juveniles are frequently observed accompanying adults at feeding sites. In some areas, the species may exhibit nomadic movements in response to climatic conditions and seasonal food availability.
Its vocalisations are pleasant and highly varied, distinguishing it from the calls of larger macaw species. When visiting clay licks, known locally as collpas, it tends to avoid the large gatherings of other parrots, instead forming small groups in the lower sections of the clay banks, either with members of its own species or alongside small groups of other parrots.
Reproduction
Little is known about the breeding behaviour of the blue-headed macaw. However, it is known to nest in natural tree cavities. The incubation period lasts between 25 and 26 days, with clutches typically consisting of two to four eggs. This information has been obtained from birds under human care.
One notable characteristic of this species is its ability to reach sexual maturity at a relatively young age, with some individuals breeding before the age of five when conditions are favourable.
Under human care, the blue-headed macaw remains an uncommon species, and only a limited number of specialised zoological institutions have successfully established stable breeding programmes.
Geographical distribution and habitat
The blue-headed macaw occurs primarily in Bolivia and Peru, with occasional records from Brazil. It inhabits humid lowland tropical forests, particularly areas close to rivers, forest edges and natural clearings surrounded by vegetation, allowing it to move through the landscape while remaining under tree cover.
It has been recorded at elevations of up to 1,550 metres, although most observations have been made below 500 metres. While it relies on well-preserved forest habitats, it has occasionally been recorded near human settlements and on the outskirts of urban areas.
Threats to the population
- IUCN Red List status: Vulnerable (VU)
- Population trend: Decreasing

Interesting facts about the blue-headed macaw
A macaw that is difficult to spot
Its secretive behaviour and tendency to remain concealed within dense vegetation make it particularly difficult to observe in the wild. It can also be distinguished from other macaw species in the region by its darker facial skin.
Early breeding
When environmental conditions are favourable, this species can reach sexual maturity before five years of age.
A name in honour of a naturalist
The species name Couloni honours the naturalist Paul Louis Auguste Coulon.
