|The Purple-naped Sunbird is known to feed on insects.
I have previously posted observations of frugivorous behaviour (a poorly recognised behaviour).
There are no reported observations of nectar feeding. Wells (2007) states “I know of no definite area record of nectarivory ....”.
I was able to document a male Purple-naped Sunbird feeding on the nectar of the same tiny flowers as Plain Sunbird Anthreptes simplex posted previously. A number of feeding episodes were seen.
Taking images of the actual feeding episodes for both the Purple-naped and Plain Sunbirds was challenging due the rapid nature of the feeding.
This forest tree varies between 5-8 metres high, has “feathery” green leaves with tiny flowers that are produced on the underside of the slender long branches. I measured the flower at 3mm in length by 2x2 mm at mouth. The tree produces tiny purple berries favoured by leafbirds and bulbuls.
