The grey-winged Inca finch is a species of bird in the family Thraupidae.
Region
Andes Mountains
Typical Environment
Occurs in arid and semiarid inter-Andean valleys, especially along the upper Marañón drainage in northern Peru. Prefers rocky slopes with sparse shrubs, cacti, and thorn scrub, as well as dry quebradas and field edges. It often forages near the ground or within low bushes, using cover to remain concealed. The species tolerates lightly modified habitats but avoids dense forest and urbanized areas. Local densities can be patchy, tied to intact dry scrub structure.
Altitude Range
1500–2800 m
Climate Zone
Arid
Ease of Keeping
Beginner friendly: 1/5
The Grey-winged Inca finch is a little-known tanager that has evolved a finch-like, heavy conical bill for cracking tough seeds. It is restricted to dry inter-Andean valleys of northern Peru, where it keeps close to thorny scrub and rocky slopes. Habitat loss from overgrazing and agriculture is its main threat, making local conservation of dry scrub crucial. Its subtle plumage blends perfectly with the stony terrain it inhabits.
Temperament
skulking and cautious
Flight Pattern
short rapid wingbeats with low, bounding dashes between shrubs
Social Behavior
Usually found in pairs or small family groups, maintaining territories within patches of scrub. Nests are placed low in dense shrubs or among rocks, where both parents attend the young. Outside the breeding season, it may join loose mixed groups but remains tied to suitable scrub.
Migratory Pattern
Resident
Song Description
A thin, high-pitched series of tinkling notes and short trills, delivered from within cover or a low perch. Calls include sharp chips used to keep contact while moving through scrub.
Plumage
Warm brown upperparts with contrasting slate-grey wings and tail; underparts pale buff to grayish with a cleaner throat. Subtle pale supercilium and fine facial markings; overall smooth, unbarred appearance.
Diet
Primarily eats seeds of grasses and shrubs, using its stout bill to husk and crush them. Supplements with small insects and other arthropods, especially during breeding when protein needs rise. Will take flower buds and occasional small fruits when available. Foraging is deliberate, often gleaning from the ground and low branches.
Preferred Environment
Feeds in open, stony scrub with scattered cacti and thorn bushes, along dry ravines and rocky slopes. Often forages at ecotones such as field edges and lightly grazed scrub where seed resources are concentrated.
