The New Holland Honeyeaters have raised one family of two chicks so far this season and another pair are in the process of building a nest. We leave some wool (fleece) out that they use in the construction process. Soft Crimson Rosella feathers lined the first nest and I think were also used to cover the eggs, when the adult was away.
I was reminded of the need to think about where nests are built when I accidentally wiped out a small nest while whipper snipping. Luckily the nest had no eggs. Wrens seem to like to nest close to the ground in a clump of grass, bracken or small shrubs.
