Collared Sunbird

The Collared Sunbird is a diminutive, brightly plumaged bird found in forest and woodland habitats across much of sub-Saharan Africa. It is one of the most widespread and familiar sunbirds in gardens and forest-edge vegetation throughout its range.

Appearance

The male has glossy metallic green upperparts, a yellow belly, and a narrow, iridescent violet-blue band crossing the upper breast like a collar, which gives the species its name. The bill is notably short and only slightly curved compared with other sunbirds. Females lack the collar, appearing simply olive-green above and pale yellow below.

Key field marks

• Very small size and a short, only slightly decurved bill (shorter than most sunbirds)
• Male: bright green upperparts, yellow underparts, and a thin purple breast collar
• Female: plain olive-green above, pale yellow below, no collar
• Frequently forages within leafy cover rather than out on exposed flowers

Similar species

The short, straighter bill separates this species from most other sunbirds, which have longer, more strongly decurved bills. The male's narrow purple collar on a clean yellow breast is diagnostic and not shared by similarly sized species like the Variable Sunbird, which shows a broader, more blotched breast pattern. Females can be confused with female white-eyes or other small green sunbirds, but the short bill and habit of hovering near foliage help confirm identity.

Habitat

This species favors forest edges, secondary growth, thickets, riverine woodland, and well-vegetated gardens, generally staying within or near cover rather than open savanna.

Range

It is broadly distributed across sub-Saharan Africa, from West Africa through the Congo Basin and East Africa south to parts of southern Africa, wherever suitable wooded habitat exists.

Migration

Collared Sunbirds are largely sedentary, though some populations shift locally in response to flowering cycles.

Behavior

Unlike many sunbirds that perch prominently on open flowering branches, the Collared Sunbird often forages actively within leafy cover, gleaning insects from foliage almost like a warbler, and frequently hovers briefly to pick prey or nectar from awkward positions.

Voice

The song is a rapid, high, twittering warble; calls include sharp, thin "tsip" or "tsee" notes given while foraging.

Feeding

It takes nectar from a wide variety of small flowers and gleans insects and spiders from leaves and bark crevices, making it more insectivorous in habits than some larger sunbirds.

Nesting

The nest is a small, oval, hanging structure woven from plant fibers, moss, and spider web, usually suspended from a slender twig or vine within dense cover. The female incubates the eggs, typically one to two per clutch.
