Now, he has photographed a Little Spiderhunter (A. longirostra) collecting nectar, also from banana flowers (above). NOTE: According to R Subaraj (see comment), the bird in the three images above is a Grey-breasted Spiderhunter (Arachnothera affinis).
The images on the left shows a Little Spiderhunter’s tongue extending beyond the tip of the bill. As with sunbirds, the tongue of a spiderhunter is also a closed tube along the major part of its length.
Spiderhunters feeding on nectar from various flowering plants is well known and extensively recorded. But feeding on spiders is not often documented. After all, these birds are called spiderhunters specifically because they are supposed to feed on spiders.
Much is not known of their animal foods and these need to be observed and documented.
