Masked Crimson Tanager

Identification

The masked crimson tanager is a compact bird measuring 18 to 19 cm in length, belonging to a genus of nine brightly coloured tanagers. The adult male is unmistakable: it displays a striking pattern of jet-black plumage on the face, wings, mantle, belly and tail, contrasted dramatically with brilliant red colouration elsewhere on the body. The bill has a distinctive silver sheen. Females are more subdued, resembling the male in pattern but with duller overall plumage and a brownish belly, while juveniles are duller still. The species bears some resemblance to the vermilion tanager, though that species inhabits higher altitudes, making confusion unlikely in the field.

Range & Habitat

The masked crimson tanager is found across Amazonia in Bolivia, Brazil, Colombia, Ecuador, Peru, and Venezuela, where it is abundant. The species shows a strong preference for wetland and riparian environments, dwelling near bodies of water such as lakes, swamps and rivers, and favouring subtropical or tropical moist shrubland. It generally remains below altitudes of 600 metres, with a particular affinity for oxbow lakes—a characteristic geographical feature of the Amazon basin.

Behaviour & Diet

These social birds move about in troops of 10 to 12 individuals and frequently form mixed-species flocks with the silver-beaked tanager, a behaviour that correlates with the extent of broad-leafed canopy in their habitat. The masked crimson tanager is primarily frugivorous, supplementing its fruit diet with small insects, particularly flying termites during the breeding season when these insects are nutrient-rich. The species also feeds opportunistically on flower nectar, and in doing so contacts the anthers with its head, making it an effective pollinator of plants such as Erythrina fusca. They produce a distinctive high-pitched single note transcribed as "tchlink" or "tink," and sing a simple melody particularly at dawn.

Best Time & Places to See It

The masked crimson tanager breeds between the dry and wet seasons in the seasonal tropics it occupies, making these transition periods potentially productive for observation. As an abundant species that prefers wetland margins and riparian zones throughout Amazonia, it can be encountered year-round across its range, particularly around oxbow lakes and river systems in lowland forest areas below 600 metres elevation.

Photography Tips

The male's striking contrast of brilliant red and jet-black plumage is highly photogenic and renders it relatively easy to identify and frame against typical rainforest vegetation. Look for birds near water margins and oxbow lakes in early morning, when dawn singing is most active. Photography is best conducted near bodies of water where the species congregates. The silver-sheened bill is a subtle but attractive detail worth capturing in good light.
