Temminck’s sunbird, Aethopyga temminckii (Müller, 1843) of Sarawak / Borneo around 600m ASL.

Aethopyga temminckii (Müller, 1843) is a species of sunbird (family Nectariniidae) found in Sundaland and recorded in Borneo in evergreen broadleaf forests, forest edges and secondary vegetation. The genus name Aethopyga is derived from ancient Greek and refers to ‘fire/burning’ (aithos) and ‘torso’ (pugē), while the species epithet temminckii honours Coenraad Jacob Temminck (1778–1858). In Borneo, the species is mentioned in Kinabalu Park, among other places. Its diet consists mainly of nectar (including from mistletoe of the Loranthaceae family) and small arthropods; nectar is taken from flowers, larger flowers (e.g. Hibiscus) can also be used by piercing the corolla tube, and short flights (‘flycatching’) have also been described in order to obtain nectar from tubular flowers. In terms of behaviour, it is mainly described as foraging alone or in pairs, occasionally joining mixed foraging groups at nectar sources; during the breeding season, territorial behaviour has been documented, with males defending their territories by singing from elevated perches and reacting aggressively to intruders.
