The bar gauge is often overlooked when buying a parrot cage. This is because most newbies have no clue what it even refers to. Generally speaking, the bar gauge is the actual thickness. This aspect might look irrelevant for small birds, yet it is more important for large parrots. Keep in mind that a strong large bird can easily bend thin bars, especially if it is placed in a cage designed for small birds. At the same time, learn from others’ past experience and determine what kind of expectations to have from one unit or another.
