HABITAT
Lowlands; variety of wooded habitats, including tropical forest and deciduous woodland, gallery forest in open country, tall scrubland, riverine secondary growth, mangroves, Pinus woodland, stands of Mauritia palms, remnant woodlots in cultivation, and suburban parks or gardens; in Amazon River basin prefers seasonally inundated forest.
BEHAVIOR
Sedentary, though some local movements with changing food supplies. Large flocks may congregate at nighttime roosts, but during the day small parties of up to 10 usually seen feeding in treetops; quiet while feeding but when disturbed, do not call until well away from tree; strong flier, flying quite high on long-distance flights to and from nighttime roosts; paired birds remain close together and readily discernible within flocks; associates with other parrots at clay-licks on exposed banks.
FEEDING ECOLOGY AND DIET
Feeds arboreally, taking seeds, nuts, fruits, berries, blossoms, and probably leaf buds; uses foot to hold fruit while extracting seeds with bill; fond of maize and cultivated fruits.
REPRODUCTIVE BIOLOGY
Monogamous. Breeding recorded mainly December–May. Nest in tree hollow, often in dead branch or decayed palm stump, also in hole excavated in arboreal termitarium; hollow prepared mostly by female for up to one month before egg-laying; clutch of two to four eggs incubated for 25–26 days by female, male remaining near nest entrance; sitting female fed by male; in captivity, young birds left nest two months after hatching.
CONSERVATION STATUS
Generally common, though locally scarce; yellow-headed subspecies (A. o. oratrix and A. o. belizensis) threatened by capture for live-bird trade and by deforestation; in 1990s population of endangered oratrix estimated at below 7,000. Listed on CITES Appendix II.
SIGNIFICANCE TO HUMANS
Reputation as excellent “talker,” so popular as pet in all parts of range; yellow-headed subspecies also in strong demand for international trade. Reported to cause damage to maize crops and in orchards.
