Southern Double-collared Sunbird

Overview

The Southern Double-collared Sunbird is a common species of fynbos, coastal scrub, and gardens in South Africa and neighboring areas. It is one of several closely related 'double-collared' sunbirds distinguished by subtle differences in breast band width and range.

Adult males show an iridescent green head and back, a narrow scarlet breast band bordered above by a thin blue-black band, and grayish underparts. Females are much plainer, olive-gray above and pale gray below, lacking the male's iridescent and banded pattern.

Feather Identification

• Body feathers: Males iridescent green on the head and back, with grayish underparts below the breast band
• Breast feathers: Narrow scarlet band bordered above by a thin, glossy blue-black band, forming the 'double collar'
• Female feathers: Olive-gray above, pale gray below, lacking bright coloring or banding
• Shaft color: Dark in the male's iridescent and banded feathers, pale in the female's plain plumage
• Size: Small and slender, typical of the genus
• Similar species: Very similar to other double-collared sunbirds in southern and eastern Africa; best distinguished by the relative width of the red breast band and range, as the bands can be narrower or wider among closely related species

Plumage Details

Adult males show an iridescent green head and back, a narrow scarlet breast band edged above by a thin blue-black band, and gray underparts. Females are olive-gray above and pale gray below, without iridescence or banding. Juveniles resemble females. There is no pronounced seasonal plumage change, with males retaining their banded pattern year-round.

Habitat & Range

This species is found in fynbos, coastal scrub, gardens, and forest edge habitats across South Africa and adjacent parts of southern Africa. It is largely resident and non-migratory, closely tied to the flowering shrubs characteristic of its native fynbos and scrub habitats.

Behavior & Field Notes

Southern Double-collared Sunbirds feed on nectar from fynbos plants such as ericas and proteas, and also take small insects, particularly when feeding young. Males defend flowering territories, chasing off rival sunbirds. Nests are small, domed structures with a side entrance, built in shrubs. Calls include sharp chips and a rapid, jumbled song, often delivered from an exposed perch within its shrubland habitat.
