I won’t take long with this. In just over a week, the female Sunbird has constructed a nest. Her and the male had been checking the spot out for a few weeks before. They threw a few strands of old grass and web over the wire, then disappeared for a day or 2. Then, last Friday (the 1st I think), the female came back and started to work in earnest. The photos below were taken between Wednesday the 6th, and Saturday the 9th of May. Mrs Sunbird has been very industrious. She has made the oval opening, and is getting inside and stretching her wings to spread the nest space. She has also been raiding some of the soft bedding feathers from the older nest on the other side of the porch/kitchen area to line the new one.
In this last image, the Sunbird is inside the nest, ruffling her feathers and stretching her wings out to make the nest space larger.
