The female is a duller green above and entirely yellow below.

Behavior
Sunbird flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time.
Habitat
Collared Sunbird is a common breeder across most of sub-Saharan Africa. Two or three eggs are laid in a suspended nest in a tree. It is a seasonal migrant within its range. This species is found in forests near water.References:
