White-bellied Sunbird Identification Guide

Key Field Marks

• Very small nectar-feeding bird, about 11-12 cm (4.3-4.7 in), with a thin, strongly downcurved bill adapted for probing flowers.
• Breeding male: iridescent green covering the head, throat, and upper breast, sometimes with a narrow dark maroon band, and a clean white belly - the white underparts are the key diagnostic feature.
• Female: plain gray-brown above and whitish to pale gray below, with an unremarkable face lacking strong markings.
• Dark, fairly short tail without elongated central feathers.

Separating It From Similar Species

• Marico Sunbird: Male has a broader dark maroon breast band and a black belly, clearly different from the White-bellied Sunbird's white belly.
• Dusky Sunbird: Male also shows a white belly but has a narrower black breast band and inhabits more arid regions farther west/south; range and breast-band width help distinguish the two.

Habitat, Range & Season

• Found in savanna woodland, thornveld, acacia scrub, and gardens across southern Africa.
• Range includes Angola, Zambia, Zimbabwe, Botswana, South Africa, and Mozambique.
• Resident year-round, though local movements may track flowering seasons.

Voice

• Gives high-pitched, sharp chirps and a lively, twittering song, typical of small sunbirds, often delivered from an exposed perch.

Behavior

• Feeds mainly on nectar from flowering trees and shrubs (including aloes), usually perching to feed rather than hovering for extended periods, though brief hovering does occur.
• Also takes small insects and spiders, especially when feeding young.
• Quick and active, frequently moving between flowering plants within its territory.
