Purple-naped Sunbird – immature

The flowers of Poikilospermum suaveolens are a particular favourite of Purple-naped Sunbirds (Hypogramma hypogrammicum nuchale) and they are territorial about them. I observed a number of Purple-naped Sunbirds coming to feed on the flowers of a Poikilospermum suaveolens and they chased away other birds, especially the Plain Sunbirds (Anthreptes simplex).

I have presumed that they eat the flowers, like many bird species, to get to the nectar; insects visiting the flowers are not eaten. They seem to choose flowers carefully and only eat some in any inflorescence. The flower is plucked and then they tilt the head backwards to swallow it.

Two of the Purple-naped Sunbirds were immatures. One was male with metallic plumage at nape and tail developing but still retaining a gape. These birds were self-feeding. Two images of the immature male.
