Ecology
The behaviour of the saffron siskin is similar to that of the hooded siskin but it usually occurs at lower elevations.[ It feeds mainly on plant material, such as seeds, leaves and buds, but also on insects, foraging among tall grasses and plants and on the ground.][ It breeds between January and May but little is known of its nesting habits.]
Status
This bird is generally uncommon and seldom seen. The total population is estimated to be under 10,000 individuals and is probably in decline because of the conversion of forest for agricultural uses. Despite the bird occurring in the Machalilla National Park
