The blue-headed macaw or Coulon's macaw (Primolius couloni) is a macaw native to eastern Peru, northwestern Bolivia (mainly in Pando), and far western Brazil (in Acre). It has a total length of about 41 cm (16 in),[3] making it a member of the group of smaller macaws sometimes known as the mini-macaws, which includes any species of macaw with a total length of 50 cm (20 in) or less. As in all macaws, its tail is long and pointed and the bill is large and heavy.

The

specific epithet couloni is in honor of Swiss naturalist Paul Louis Coulon (1804-1894).[4]

Description

The blue-headed macaw is 41 cm (16 in) long. It has mainly green plumage (often tinged olive, esp. below) with the head,

flight feathers and primary coverts blue. The uppertail has a maroon base, a narrow green center and a blue tip. The undertail and underwing are greenish-yellow similar to that of several other small macaws (e.g. red-bellied and golden-collared macaw). The medium-sized bill is pale greyish-horn with a black base (extent varies, but upper mandible in adults typically appears mainly pale). The iris is whitish with a narrow, often barely visible, maroon eye-ring. Unlike most other macaws, the facial skin and lores are dark greyish. The legs are dull pinkish. Juveniles
resemble adults, but with the entire bill black, greyer legs, darker iris and the facial skin and lores white.

Taxonomy

In recent years it has often been placed in the

Ara
, which, at present, is only used for some of the larger macaws.

Habitat

It is found in the south-west

clay-licks
.

Behavior

Little is known about its reproductive behavior in the wild, but a possible nest has been recorded in a bamboo cavity and another in a tree cavity. In captivity, the reproductive cycle appears to be roughly annual with a clutch size of 2-4 being the norm. In the wild it is typically seen in groups of 2-4 individuals, with occasional records of groups up to c. 60 individuals. Its call is higher-pitched and softer than that of most other macaws.

Status

Until recently it was considered fairly common, but a review in 2006 by

endangered in the 2007 IUCN Red List.[1] Parts of the range of this species remain poorly known, but Tobias & Brightsmith (2007) has suggested that previous estimates were too low, with actual number of 9200-46000 mature individuals more likely. It has therefore been suggested that vulnerable
might be a more appropriate category for this species.

Much of the forest within its range remains intact, but habitat loss could be a threat, at least locally. It occurs in several protected areas, e.g.

Manu
.

The capture of individuals for the wild bird trade potentially presents a serious problem. It is rare in captivity and consequently prices are high (US$12,500 but the past few years have declined as low as $4,000 - 5,000 US in some EU countries). International trade in this species was virtually unknown in 1993, where

International Species Information System listed only 26 individuals in zoos outside its native countries, and Loro Parque (not included on ISIS) has 35+ individuals. CITES reported that approx. 50 illegally held blue-headed macaws were seized throughout the World in 1993–2000, and an investigation in Germany
in 2001 resulted in approx. 30 individuals being seized.
