I am hoping the brains trust out there will help us to answer this. A friend 
has been observing Eastern Spinebills in her garden in the lower Blue Mountains 
for many years. She posed these question about their nesting habits:
> My observations on eastern spinebills’ nest-feathering has prompted me to ask 
> more questions around “which came first :- the feather or the egg?”.  When we 
> first moved to the mountains in the early 1960’s, Sulphur-crested cockatoos 
> were not seen regularly, & certainly not in the large flocks of today. 
> the Spinebill nest in our front hedge a few summers ago was completely lined 
> with feathers, & more than 90 % of them were white.  so I wonder if 
> previously the Spinebills may have used other white birds’ feathers (like 
> chooks??), or used a different coloured feather for the main nest-lining & 
> side-walls.  I also wonder if the abundance of available white feathers these 
> days has stimulated successful nesting behaviour in Spinebills, & also of 
> course if in areas where large white feathers are not available, the 
> Spinebills breed at the same rate as the white-feather-nest-liners.  Or if 
> the whole white-feather-lining is just a localised behaviour, or just 
> happened in our front yard once... it would be very interesting to hear any 
> other observations, please.
