Collared Sunbird is quite normal and easy to find in sub-Saharan Africa, excluding the area of south-west Africa. Two or three eggs are laid in a suspended nest in a tree. It is a seasonal migrant within its range. It only 9-10 cm long. They have short thin down-curved bills and brush-tipped tubular tongues, both adaptations to nectar feeding. The adult male has glossy green upperparts and head with a yellow belly and narrow purple breast band. The female is a duller green above and entirely yellow below.
