olive-backed sunbird female

The garden sunbird (Cinnyris jugularis)

olive-backed sunbird

 It is widely common across southern China to the Malay Peninsula, Sumatra, Borneo, Philippines, Java and Australia. 

It is  described as a very common in suburban and urban habitats, but this bird is rarely seen at my backyard, compare with Brown-throated sunbird that regularly feed on Bird of Paradise Flower.(Heliconia psittacorum Nickeriensis) 

I have seen  the olive-backed sunbird feeds  on nectar extracted from the base of blooms hibiscus
