Alternative names: Oleaginous Tanager; Ochraceous Hemispingus; Merida Hemispingus
- Hemispingus frontalis
Identification
14cm. A dull hemispingus with a relatively slender bill.
- Long, narrow and weakly indicated yellowish supercilium, more pronounced in northern subspecies
- Dull dirty olive crown, upperparts and tail
- Dingy olive-yellow underparts, more olive on sides
- Dusky grey, relatively slender bill
Sexes similar. Juveniles lacks supercilium.
Distribution
South America: found in the Andes of Colombia, Venezuela, Ecuador and Peru.
Fairly common in its range.
Taxonomy
Subspecies[1]
Five subspecies are recognized:
- H. f. frontalis:
- H. f. ignobilis (Ochraceous or Merida Hemispingus - suggested that it might merit elevation to species rank):
- Andes of western Venezuela (southern Lara, Trujillo, Mérida and Táchira)
- H. f. flavidorsalis:
- H. f. hanieli:
- Coastal mountains of northern Venezuela (Aragua to Miranda)
- H. f. iteratus:
- Coastal mountains of north-eastern Venezuela (Monagas to Sucre)
The closest relative seems to be Black-eared Hemispingus. Both species are now placed in the genus Sphenopsis by Clements.
Habitat
Moist montanes.
Occurs at 1,400 to 2,900m.
Behaviour
Feeds on arthropods.
Usually seen in pairs, family parties or small groups in understorey mixed-species flocks. A dead-leaf specialist, works trough undergrowth, flying a few metres and hopping up branches while flicking its tail.
Birds in breeding condition from June to November in Venezuela, juvenile in April in Peru. Eggs white. No other information about breeding.
A resident species.
