Loke Peng Fai’s image shows an Olive-backed Sunbird (Cinnyris jugularis) hovering in front of a flower of the Firecracker Plant (Russelia equisetiformis) (above). It has its bill deep inside the flower. Its tongue, like in all members of the family Nectariniidae except the Ruby-cheeked Sunbird, is tubular. This allows nectar to be taken by capillary action (Cheke & Mann, 2008).
Subaraj Rajathurai has confirmed that the Olive-backed Sunbird is an eclipse male, as shown by the presence of black streaks down its throat and breast (above).
The normal method of foraging for nectar is by moving through the branches of the plant to get at the flowers, as shown in this video.
Hovering provides an additional method of feeding, especially where there are no convenient perches around the flowers. Hovering also comes into play when searching for insects
Earlier posts show hovering by Olive-backed Sunbird, Crimson Sunbird (Aethopyga siparaja) and the New World hummingbirds.
