The western hemispingus is a species of bird in the family of Thraupidae. It is found in Ecuador and Colombia. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest.
Region
Northern Andes
Typical Environment
Occurs on the western and central Andes of Colombia south into northwestern Ecuador. It inhabits subtropical and tropical moist montane forests, especially along forest edges, gaps, and second-growth thickets. The species frequently uses bamboo (Chusquea) tangles, mossy understory, and epiphyte-laden midstory to glean arthropods. It can persist in heavily degraded former forest provided sufficient dense cover remains.
Altitude Range
1400–3200 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
The western hemispingus is a small Andean tanager that forages actively in the midstory and understory, often joining mixed-species flocks. It was formerly placed in the genus Hemispingus and is now commonly treated in Sphenopsis. Its subtle plumage makes it easy to overlook, but its sharp contact notes often reveal its presence. It tolerates lightly disturbed habitat and secondary growth near humid montane forest.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically forages in pairs or small groups and is a regular participant in mixed-species flocks moving along forest edges and midstory. Nests are cup-shaped and placed low to mid-level in dense vegetation. Both sexes likely share parental duties, and territories are maintained mainly during the breeding season.
Migratory Pattern
Resident
Song Description
The voice is a series of thin, high-pitched chips and short trills delivered from cover. Calls are sharp and sibilant, often used to keep contact while moving with mixed flocks.
