Piones Blue headed, Paler basic information
The Paler Blue Headed Pionus is not sexually dimorphic and therefore will need either DNA or surgical sexing to distinguish males from females. They have a uniformly colored dark green plumage on their bodies and striking blue plumage that covers their necks and heads. They also have distinct pink feathers on the plumage the covers their necks. This color is more pronounced than that seen in the nominant form (P. m. menstruus). The nominant subspecies also has brighter blue coloring on its head and neck when compared to the Paler Blue Head. The Reichenow's Blue Headed Parrot lacks the pink plumage entirely and is easy to distinguish from the other two for this reason. Like other Pionus species, Paler Blue Headed Pionus have red feathers underneath their tails. They have dark grey legs and feet and red markings on their mandibles. Immatures may be distinguished by the fact that they have very little blue plumage on their heads. They will reach full coloring by 2 years, though after the first molt, they usually have a significant increase in blue color. Paler Blue Headed Parrots are medium sized, averaging 11 inches (27.5 centimeters) in length.
