This entry covers records of the nominate subspecies P. o. obscura in southern Paraguay. The paper reports reddish irises in an observed male and brown irises in an observed female.
In observations from southern Paraguay, the male had a reddish iris and the female a brown iris. The paper uses these photographed birds to discuss sex identification in that local record.
Dusky-legged Guans eat fruit from many plant species in southern South American forests. A University of Barcelona field-video account documents a bird near Intervales State Park, Brazil.
A Serra do Japi study compared an area with human food supply and an area without it. Provisioned birds were seen more often but moved less and dispersed fewer native plant species in their droppings.
Food locations can influence movements and plant–bird interactions. Understanding these relationships supports conservation of forest food resources and ecological functions.
An extinction-risk assessment has not been added yet.
Research documents changes in movement and native-seed dispersal associated with human food supply. Conserving natural food plants and forest habitat supports the bird’s ecological relationships.
