wood and metal toxicity, organic food, and cage-top playpen
Is linden wood toxic (tilia) for parrots ? (it is not on Dr Vanden's list)
Is nickel plated metal parts of toys toxic for birds ?
(I know that zinc is)
Is it worth buying organic food for parots ?
Do playpens on top of cages cause territorial behaviour ? If so, does it depend on the height of the bird compared to us ?
