"Tiny Beauty", Southern Double-collared Sunbird Is A Star Of The Forest (8 Photos)
Where the Americas have hummingbirds, the Old World has sunbirds; brightly coloured jewels that flash in the light. The males often wear showy colours which makes identification straightforward while females tend towards the dull and difficult (my non-birding, proof-reading wife has just suggested that I change that last sentence, but you know what I mean).
I was able to re-attach the nest about 1m from its original position. The adults continued to feed the chicks, none the worse for wear and they eventually fledged.
