Afrikaans name: Swartsuikerbekkie
Nectarinia amethystina / Chalcomitra amethystina
I think that the old name of Black Sunbird is better suited to this species as males are predominantly black with only a small patch of amethyst colour on their throat.
The male Amethyst Sunbird is as I have described above. The female is far more drab with a brown back and blotches and streaks of black on her underparts.
They are found in many countries in Africa. In South Africa they occur in a band from the Western Cape through KwaZulu-Natal to North West Province.
The Amethyst Sunbird mainly feeds off nectar but does also eat spiders and it catches flying insects.
The female makes the nest which is an enclosed structure hanging from a twig. Up to 3 eggs are laid.
