I have seen and bought different sized wooden boxes from different places. Some call them gouldian boxes, others say budgie boxes.

These ones are all the same but I do have a couple on the other wall that are narrower.
Gouldians, fire finches, emblema and BF and RT parrot finches have used these. This is the type I have most of. The parrot finches tend to make a really thick lined nest in these boxes and they like feathers as do the fire finches. Some gouldians are rubbish nest builders so I usually start some nest boxes off with the coconut fibre and swamp grass, others I put just a bit in and others I leave empty.
I also have the woven wicker type nests, large and small. The orange breasted waxbills prefer the smaller ones, emblema have made nests in the larger ones before, emblema dont seem to be fussy, they will build anywhere. See this topic
