After not entering my backyard for almost a month, I discovered a nest which was built right outside my kitchen window. It belonged to a female sunbird. Its hard to tell which sunbird it is because female sunbirds look almost identical. However I suspect that its an Olive-backed because they're quite common in Malaysia.
The process of between laying eggs, eggs hatching and the chicks leaving the nest took around 3-4 weeks. Equipment used are a Nikon 300, off-shoe SB-800, Nikon 105mm f/2.8 AFS-VR macro lens and a 1.7x teleconverter(for some shots).
