Many times when I venture into the bush I realise how little I understand about the natural world.
I was intrigued recently to see a pair of Red-browed Firetails nest-building in a Hedge Wattle at Rotunda Park. If conditions are suitable Red-browed Firetails will breed in spring and autumn, but watching this behaviour made me wonder if they may be making a roosting nest. The nest itself was in the early stages of construction – the base was well advanced but only the beginnings of the roof could be seen
Diamond Firetails, another local finch, also make elaborate dome-shaped nests that they breed in and then use for night-time roosting during the cooler months. I’m not aware if Red-browed Firetails (which belong to a different genus) also employ this strategy.
PS: Another big tick for the revegetation works at Rotunda Park – Hedge Wattle is fantastic breeding habitat for small birds such as finches, thornbills, wrens and honeyeaters.
