Behavior

Movement

The red-faced guan is thought to be largely sedentary, but some altitudinal movement has been reported in Argentina.

Feeding

The red-faced guan usually forages in pairs but larger groups have been reported. It mostly forages in trees but also feeds on the ground. Its diet is mostly fruits and it also eats leaves and

Breeding

The red-faced guan's breeding season has not been fully defined, but displaying and calling pairs have been documented between September and December. It builds a platform nest of twigs and stems lined with leaves and sited in a tree. The clutch size is three eggs.

Vocal and non-vocal sounds

The red-faced guan makes a wing-whirring display at dawn. Its song is "random-sounding gruff notes, given in level series". Its alarm call is "a loud, throaty and repeated 'kroa, kroa...' interspersed by whistled notes 'luuuii'."

Status

originally assessed the red-faced guan in 1988 as Threatened but since 2004 has rated it as being of Least Concern. Though it has a restricted range, it occurs in several protected areas and its generally remote and inaccessible habitat make for less hunting pressure than most other guans receive.
