SPIX'S MACAW 

 

Cyanopsitta  spixii  (Wagler 1832)

 

German: Spixara

 

Description: general plumage dull blue; breast and abdomen with faint greenish tinge; back and tail upperside deeper blue; bare lores and cheeks dark grey; ear-coverts and forehead pale grey-bluish; under side of tail and wing-coverts dark grey; bill blackish; iris pale yellowish; feet grey.

 

Immatures with shorter tail; upper mandible horn-coloured with blackish sides; iris brown.

 

Length: 56 cm (22 ins).

 

Distribution: northeast Brazil, formerly in southern Piauí and northwest Bahia; possibly also most southerly area of Maranhão, northeast Goiás and Pernambuco.

 

Habitat: flat country with caatinga-type thorn-bush vegetation and tall trees along water courses; possibly also open country with palms and isolated groups of trees.

 

Status: extremely endangered; wild population probably extinct; attempts are being made to reintroduce captive birds to rebuild population; was never common; causes for collapse of wild population trapping, hunting and possibly also introduced African bees taking over nesting sites.

 

CITES: classified CITES I on 07/01/1975

 

Habits: usually singly, in pairs or small family groups; were regularly observed along rivers; there conspicuous as they perched on top branches of bare trees; shy and unapproachable; occasionally observed with Illiger's Macaw (Primolius maracana); Spix's Macaw however dominant; drove Illiger's Macaw from preferred perches; flight with slow, deep wing-beats and reminiscent of large macaws; flight high over vegetation accompanied by continuous kraa-ark calls; roosting trees not used all year; occasionally macaws roosted in tall cactus or disappeared for several weeks from an area; apart from this day fairly routine; same flight path used to and from feeding places; long distances often covered.

 

Natural diet: mainly seeds of faveleira (Cnidoscolus phyllacanthus) and pinhao tree (Jatropha pohliana); in addition fruits and seeds of other types of vegetation e.g juazeiro (Ziziphus joazeiro) or bom-nome (Maytenus rigida); fruits of facheiro cactus (Cereus sp.).

 

Breeding behaviour: breeding season between November and March; nested in hollows of old craibeira trees (Tabebuia caraiba); same nest-holes tended to be used every year; eggs and young failed often because African bees killed brooding female or occupied nest-holes; also young taken from nest; clutch usually 2 to 3 eggs; nests also generally held two or three young; these appeared to need feeding more often as they had smaller crop than other macaws; egg measures 41.3 x 30.6 mm (1.63 x 1.20 ins).

 

Aviculture: lively and sometimes noisy bird; wild-caught initially shy and nervous, but mostly soon become accustomed to keeper; can be aggressive even outside breeding season; inquisitive and playful; if threatened lies on ground; provide regular supply of fresh branches and tree stumps as hard chewers; acclimatised birds hardy; can also be kept in groups outside breeding season; much enjoys bathing.

 

Accommodation: ideally very large aviary with adjoining shelter 3 x 2 x 2 m ( 9 x 6 x 6 ft); metal structure with very strong mesh essential; should be in quiet location as Spix's Macaws distracted and easily disturbed especially during breeding season; minimum temperature 20°C (68°F); inside area should have plenty of perches; tree stump 35 cm (14 ins) in diameter and 70 cm (28 ins) high with entrance hole 10 cm (4 ins) wide.

 

Diet: various fruit and vegetables (especially rose-hip, rowanberries, apple, plum, banana, cucumber, half-ripe maize and carrot): seed mix of safflower, hemp, sunflower, wheat, oats, canary grass seed and various millets; also sprouted in summer; soaked pigeon food; small quantities of pine-nuts; greenfood (chickweed, dandelion etc.); regular vitamin (especially D and B complex) and mineral supplements; small quantities of cooked beef; eggfood, porridge and rusk for rearing.

 

Breeding in aviculture: achieved several times; breeding begins in August; no courtship display; signalled by mutual feeding, longer periods of treading (often 5 to 10 minutes) and increasing aggressiveness towards keeper; clutch 2 to 4 eggs; not all eggs fertile; laid at two day intervals; incubation 26 days; fledging period 2 months; young fed by parents for up to 3 months after leaving nest; position nesting stump to allow inspection from outside aviary; adults sensitive to disturbance during breeding.
