Primolius is a genus of macaws comprising three species, which are native to South America. They are mainly green parrots with complex colouring including blues, reds and yellows. They have long tails, a large curved beak, and bare facial skin typical of macaws in general. They are less than 50 cm long, much smaller than the macaws of the Ara genus.

Physical charateristics

Primarily green, Yellow-collared Macaws have a bare white facial patch, a blackish green forehead and nape, a narrow yellow collar which reaches to the sides of its breast, blue on the primaries and primary coverts and a red and blue tail

These parrots can be found in gallery woodland in Pantanal, deciduous Chaco woodland, agricultural plots and ranchland and humid tropical forest. Occurs in variety of habitats such as forest, forest edge, woodland and savanna; moist upper tropical and subtropical forest in Argentina, dry forest in Bolivia, chaco in Paraguay and pantanal, open cerrado and gallery forest in Brazil. Up to 600m (1968 ft), in some areas 1700m (5576 ft).

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat
Golden-collared Macaw status Least Concern


Resident. Flocking behavior has been observed in Yellow-collared Macaws outside of their breeding season, fueling the suggestion that these birds undergo local seasonal movements.
