A 2024 U.S. Fish and Wildlife Service notice describes the Sira Curassow as endemic to central Peru, resident in cloud forest at 1,100–1,500 m, and known only from the Cerros del Sira.
The notice describes both curassow species as 83–94 cm long and about 3.6 kg, with bright red bills and pale blue casques.
Sira Curassows have red bills and blue casques and inhabit Peru’s Sira mountains. Ground cameras have documented their movements away from human observers.
On19 June2015, a juvenile followed an adult. Its blue casque was not conspicuous. The survey also recorded a rare brown-barred plumage morph.
During March–September2015,19 bird-monitoring cameras produced19 independent detections at1,150–1,500m. These observations documented appearance and habitat occurrence.
An extinction-risk assessment has not been added yet.
Hunting and habitat destruction threaten its restricted Sira forest range. The2017 study documented human activity within elevations used by the birds, helping identify overlap relevant to conservation.
