Distribution
Endemic to interior of northeast Brazil from south Maranhão east across Piauí, Ceará, Paraíba and Pernambuco, south to Alagoas, Bahia and northeast Minas Gerais.
A vulnerable species with probably fewer than 10,000 birds split in three subpopulations.
Taxonomy
This is a monotypic species[1].
Habitat
Found in dry parts of semi-deciduous forest and taller caatinga, sometimes also in campo rupestre. Can persist in selectively logged and degraded areas.
Occurs in lowlands below 1000 m.
Behaviour
Diet
Recorded to feed on seeds and fruit (eg of Ziziphus joazeiro).
Often forages on ground for fallen fruits, seeds and some insects. Also visits water to dring, especially during dry season or in years with low rainfall.
Usually in small groups of up to seven birds, more in feeding areas.
Breeding
Not much known. Juveniles recorded in mid August. The nest is made of sticks and lined with dry leaves. It's placed in trees or palms. Lays 2 to 3 white eggs.
Movements
Presumably a sedentary species with short-range movements according to food and water availability.
