Introduction Despite the fact that the appearance of natural structures change, reality will always remains (Honour & Fleming, 2005). In order to create pure reality, it is imperative to reduce natural forms to constant elements of form. Birds, when properly taken care of, will seldom be attacked with any disease. A good practice, therefore, is to ensure that the birds are punctually fed, kept in a healthy and clean environment, and placed in safe, comfortable cages. Ordinarily, if a bird gets sick, it is by neglect of the above simple precautions. This paper provides a discussion about the bird cage. Most cage birds shed their feathers yearly, in the month of September and October, and lasting, with a healthy bird, from two to four weeks (Willett, 2006). Although the process of cage birds shedding feathers is a natural one, it is generally accompanied with disease. They must at this time, be particularly taken care of. With bare feathers, they are more liable to be affected by cold. They should, therefore, be kept in a rather warmer place than usual. Above all, they should be protected from a draught of air (Perry, 2007). A good deal of room to fly about, for example, allows them to drop their feathers more easily. A great trouble to birds in confinement, are insects such as small reddish lice which often cause the death of cage birds. They are generally produced by uncleanness, and will, particularly in wooden cage, increase very fast. The insects hide themselves during the day in crevices and creep out at night, crawl up to the birds, and torment them mercilessly. They suck blood out of them and prevent them from getting rest the whole night. The bird thus tormented, appears dull and heavy during the day, ceases singing, and if relief is not given to them, the unfortunate end result is death. It is for this reason and many others that bird owners must pay attention to the kind of cage to be used by their birds. Environmental Considerations One of the most important owner influences on a bird’s health is its environment. An environment that promotes psychological well being leads to a happy, healthy, and reproductively active bird. For small cage birds, a large cage or aviary will allow for flight and space needed to reduce territorial stress that is often associated with common species maintained in captivity (Murillo, 2011). Overcrowding leads to injury and stress. Aviary design is often based on an individual’s imagination and monetary investment. Aviaries can be small areas within a house or large outdoors flights. Large free flight aviaries require plants for hiding, perception of safety, and building of nests. Maintenance is often required with free flight aviaries because small birds have a habit of pulling the leaves off the plants and trees within the enclosure. As with the aviaries, rodent, and vermin control is very important. Rodents and insects are drawn to the food debris produced by pet birds. Bird food not stored properly is also a magnet for rodents and insects. In the southeastern United States, fire ants, drawn to an aviary by spilled food, are potential deadly pests to young chicks.
