Olive-backed Sunbird: Removal of faecal sac

on 2nd July 2009

It is always exciting to witness an adult Olive-backed Sunbird (Cinnyris jugularis) arriving at the nest where the chick, with its head sticking out of the entrance, bill gaping wide, begged loudly to be fed. Photographers have always documented such intimate moments, not to mention when the adult inserted its long bill deep in the throat of the chick, as if to place the food morsel right inside the crop.

However, the removal of faecal matter immediately after the feeding has not been always photographed. This time, after the chick was fed and it turned around and offered its posterior end to the adult, Mark G. a.k.a. strobby was ready. When a whitish faecal sac emerged from its vent and the adult gingerly picked it, he documented the moment (left).

The adult flew off to dispose the sac elsewhere so that the wastes do not collect below the nest and attract the attention of potential predators by the smell.

This post is a cooperative effort between NaturePixels.org and BESG to bring the study of bird behaviour through photography to a wider audience.
