Records from Santo Tomé

Conservation status according to BirdLife International: Least Concern

Synonyms: Cuculus guira.


Description: A distinctive, medium-sized bird with an elongated body and a somewhat scruffy look, featuring plumage in cream, cinnamon and black tones arranged in an irregular pattern. Its long, pointed crest feathers give it a disheveled appearance. The bill is strong and orange, and the long tail shows bold dark barring. The wings are short and broad, producing a clumsy, low and generally brief flight; the species usually moves through low perches or short hops rather than sustained aerial travel.

Geographic distribution: Widely distributed across eastern South America, from southern Amazonia to northern Argentina, Uruguay, Paraguay and large portions of central-eastern Brazil. It thrives in open and semi-open habitats and readily persists in modified landscapes.

Habitat: Prefers warm, open or semi-open environments such as savannas, grasslands, shrublands, forest edges, small farms and suburban areas with scattered trees. It adapts efficiently to human-altered habitats as long as some shrub cover and elevated perches are available.

Diet: Primarily omnivorous with a strong insectivorous tendency. It searches for prey among low branches, open ground and grasslands, taking large insects, small vertebrates, lizards, frogs and occasionally eggs or nestlings of other birds. It supplements its diet with fruits, especially when animal prey is less abundant.

Behavior: Highly gregarious, commonly seen in groups of variable size that maintain constant contact through loud, raspy calls. It spends much of the day moving through low vegetation, climbing among branches and shrubs. Its flight is short and noisy, and it often prefers running or hopping rather than taking long flights. Its curious nature and exploratory behavior make it a conspicuous and easily observed species.

Breeding: Exhibits a cooperative breeding system, with several individuals collaborating in nest building, incubation and chick rearing. It constructs a bulky, loosely arranged stick nest, usually placed at mid-height in trees or shrubs. Multiple females may lay eggs in the same communal nest, resulting in large combined clutches. Incubation is shared, and chicks are fed by several adults from the group.

Conservation status: Classified as Least Concern (LC). Its wide distribution, high local abundance and strong adaptability to diverse and human-modified environments support stable populations across most of its range.
