thanks for the heads up, but ive unfortunately already found out tiels will, and budgies try, to tear up anything wood or otherwise, when in nesting mode. tiels even tore off chunks of plastic, bars and perches of finch cages, though the very minimal damage of budgies was neat, as unknown sex albino, would keep digesting and chewing down wood to paste and spit and spread etc in nest box and before that corner of cage, as other, who was the mounter and cere sexed as male, would just dance around other and nest and hardly chew, except to get other's attention, but he was never allowed by other in nest box, and would just spit the wood paste glue into the other's mouth (nerdgasm for those scientific types who dont have weak stomachs). so will be keeping at least one pair or destructive tiels separate if they dont stay calm, like presently are with new nest box (funny all expensive old wood boxes would do for nests for them, but they immediately took up in two hanging planters put together and hung in huge old cage, with access hole on bottom of top one and drainage plastic bottom liner with shallow terracotta pot with some hay, but male chewed apart the thick wood one), but probly be aviary just for finches, diamond doves (when find a pair or two. anyone know how easy it might be to raise or foster chicks to finches out of shipped eggs?), and "button" quail. odd, budgies do still play alot with toys and alot of antics, even though pair up sometimes so much albino gets saddle sore on back and head, and other times lately that letting free fly, they just act friendly, but when cage for some reason rarely now, they go right to acting extremely bonded and starting to nest even again.
