Bird Perches
One of the more interesting forms of customization that stems from the investment in a pet bird is the bird perches. With the perches you get to customize a rather generic cage, which may or may not be on a stand, with the furniture equivalent for the bird. Birds do not need a whole lot of things to be happy, the cage provides them a volume of free space which is useful in giving them more freedoms that a ball and chain, but less than the open air.
Bird perches can be used to link different portions of the cage together. This can be done on either vertical, horizontal, diagonal axis to create different surfaces and various angles for your bird to enjoy. All in all the generic uses for the bird perches, be them natural and chewable, hard immobile plastic, or bendable adjustable rubber, are used to customize the atmosphere of the bird in question. The different levels of adjustment make the cage one of the most customizable portions of the entire bird pet package, with the exception of the initial purchase of the bird.
